Aristotle, on the contrary, held that all of our knowledge begins with "the singular," that is, with the particular and the relative, and is derived from sensation and experience. The "sensible object," taken as it is without any sifting and probing, is the basis of science, and reason is simply the architect constructing science according to certain "forms" or laws inherent in mind. The object, then, of metaphysical science is to investigate those "universal notions" under which the mind conceives of and represents to itself external objects, and speculates concerning them. Aristotle, therefore, agrees with Plato in teaching "that science can only be a science of universals,"691and "that sensation alone can not furnish us with scientific knowledge."692How, then, does he propose to attain the knowledge of universal principles? How will he perform that feat which he calls "passing from the known to the unknown?" The answer is, bycomparative abstraction. The universal being constituted by a relation of the object to the thinking subject, that is, by a property recognized by the intelligence alone, in virtue of which it can be retained as an object of thought, and compared with other objects, he proposes tocompare, analyze, define,andclassifythe primary cognitions, and thus evoke into energy, and clearly present those principles or forms of the intelligence which he denominate "universals." As yet, however, he has only attained to "general notions," which are purely subjective, that is, to logical definitions, and these logical definitions are subsequently elevated to the dignity of "universal principles and causes" by a species of philosophic legerdemain. Philosophy is thus stripped of its metaphysical character, and assumes a strictlylogicalaspect. The key of the Aristotelian method is therefore the

ARISTOTELIAN LOGIC.
Pure Logic is the science of the formal laws of thought. Its office is to ascertain the rules or conditions under which the mind, by its own constitution, reasons and discourses. Theoffice of Applied Logic--of logic as an art--is "to form and judge of conclusions, and, through conclusions, to establish proof. The conclusions, however, arise from propositions, and the propositions from conceptions." It is chiefly under the latter aspect that logic is treated by Aristotle. According to this natural point of view he has divided the contents of the logical and dialectic teaching in the different treatises of theOrganon.
The first treatise is the "Categories" or "Predicaments"--a work which treats of the universal determinations of Being. It is a classification of all our mental conceptions. As a matter of fact, the mind forms notions or conceptions about those natures and essences of things which present an outward image to the senses, or those, equally real, which utter themselves to the mind. These may be defined and classified; there may be general conceptions to which all particular conceptions are referable. This classification has been attempted by Aristotle, and as the result we have the ten "Categories" ofSubstance, Quantity, Quality, Relation, Time, Place, Position, Possession, Action, Passion. He does not pretend that this classification is complete, but he held these "Predicaments" to be the most universal expressions for the various relations of things, under some one of which every thing might be reduced.
The second treatise, "On Interpretation," investigates language as the expression of thought; and inasmuch as a true or false thought must be expressed by the union or separation of a subject and a predicate, he deems it necessary to discuss the parts of speech--the general term and the verb--and the modes of affirmation and denial. In this treatise he develops the nature and limitations of propositions, the meaning of contraries and contradictions, and the force of affirmations and denials inpossible, contingent, andnecessarymatter.
The third are the "Analytics," which show how conclusions are to be referred back to their principles, and arranged in the order of their precedence.
The First or Prior Analytic presents the universal doctrineof the Syllogism, its principles and forms, and teaches how must reason, if we would not violate the laws of our own mind. The theory of reasoning, generally, with a view to accurate demonstration, depends upon the construction of a perfect syllogism, which is defined as "a discourse in which, certain things being laid down, something else different from the premises necessarily results, in consequence of their existence."693Conclusions are, according to their own contents and end, eitherApodeictic, which deal with necessary and demonstrable matter, orDialectic, which deal with probable matter, orSophistical, which are imperfect in matter or form, and announced, deceptively, as correct conclusions, when they are not. The doctrine of Apodeictic conclusions is given in the "Posterior Analytic," that of Dialectic conclusions in the "Topics," and that of the Sophistical in the "Sophistical Elenchi."
Now, if Logic is of any value as an instrument for the discovery of truth, the attainment of certitude, it must teach us not only how to deduce conclusions from premises, but it must certify to us the validity of the principles from whence we reason and this is attempted by Aristotle in the Posterior Analytic. This treatise opens with the following statement: All doctrine, and all intellectual discipline, arises from a prior or pre-existent knowledge. This is evident, if we survey them all; for both mathematical sciences, and also each of the arts, are obtained in this manner. The same holds true in the case of reasonings, whether through [deductive]Syllogismor throughInduction, for both accomplish the instruction they afford from information previously known--the former (syllogistic reasoning) receiving it, as it were, from the traditions of the intelligent, the latter (inductive reasoning) manifesting the universal through the light of the singular.694Induction and Syllogism are thus the grand instruments of logic.695

Footnote 695:(return)"We believe all things through syllogism, or from induction."--"Prior Analytic," bk. ii. ch. xxiii.
Both these processes are based upon ananteriorknowledge. Demonstrative science must be from things true, first, immediate, more known than, prior to, and the causes of, the conclusion, for thus there will be the appropriate first principles of whatever is demonstrated.696The first principles of demonstration, the material of thought, must, consequently, be supplied by some power or faculty of the mind other than that which is engaged in generalization and deductive reasoning. Whence, then, is this "anterior knowledge" derived, and what tests or criteria have we of its validity?
1. In regard to deductive or syllogistic reasoning, the views of Aristotle are very distinctly expressed.
Syllogistic reasoning "proceeds from generals to particulars."697The general must therefore be supplied as the foundation of the deductive reasoning. Whence, then, is this knowledge of "the general" derived? The answer of Aristotle is that the universal major proposition, out of which the conclusion of the syllogism is drawn,is itself necessarily the conclusion of a previous induction, and mediately or immediately an inference--a collection from individual objects of sensation or of self-consciousness. "Now," says he, "demonstration is from universals, but induction from particulars. It is impossible, however, to investigate universals except through induction, since things which are said to be from abstraction will be known only by induction."698It is thus clear that Aristotle makesdeduction necessarily dependent upon induction. He maintains that the highest or most universal principles which constitute the primary and immediate propositions of the former are furnished by the latter.

2. General principles being thus furnished by induction, we may now inquire whence, according to Aristotle, are the materials for induction derived? What is the character of that "anterior knowledge" which is the basis of the inductive process?
Induction, says Aristotle, is "the progression from singulars to universals."699It is an illation of the universal from the singular as legitimated by the laws of thought. All knowledge, therefore, begins with singulars--that is, with individual objects. And inasmuch as all knowledge begins with "individual objects," and as the individual is constantly regarded by Aristotle as the "object of sense," it is claimed that his doctrine is that all knowledge is derived fromsensation, and that science and art result to man (solely) by means ofexperience.He is thus placed at the head of the empirical school of philosophy, as Plato is placed at the head of the ideal school.
Footnote 699:(return)"Post. Analytic," bk. i. ch. xviii.
This classification, however, is based upon a very superficial acquaintance with the philosophy of Aristotle as a whole. The practice, so commonly resorted to, of determining the character of the Aristotelian philosophy by the light of one or two passages quoted from his "Metaphysics," is unjust both to Aristotle and to the history of philosophic thought. We can not expect to attain a correct understanding of the views of Aristotle concerning the sources and grounds of all knowledge without some attention to his psychology. A careful study of his writings will show that the terms "sensation" (αὶσθησις) and "experience" (ἐµπειρία) are employed in a much more comprehensive sense than is usual in modern philosophic writings.
"Sensation," in its lowest form, is defined by Aristotle as "an excitation of the soul through the body,"700and, in its higher form, as the excitation of the soul by any object of knowledge. In this latter form it is used by him as synonymous with "intuition," and embraces all immediate intuitive perceptions, whether of sense, consciousness, or reason. "The universe is derived from particulars, therefore we ought to have a sensible perception (αὶσθησις) of these; and this is intellect (νοῦς)."701Intelligence proper, the faculty of first principles, is, in certain respects, a sense, because it is the source of a class of truths which, like the perceptions of the senses, are immediatelyrevealed as facts to be received upon their own evidence. It thus answers to the "sensus communis" of Cicero, and the "Common Sense" of the Scottish school. Under this aspect, "Sense is equal to or has the force of Science."702The term "Experience" is also used to denote, not merely the perception and remembrance of the impressions which external objects make upon the mind, but as co-extensive with the whole contents of consciousness--all that the minddoesof its own native energy, as well as all that itsuffersfrom without. It is evidently used in the Posterior Analytic (bk. ii. ch. xix.) to describe the whole process by which the knowledge of universals is obtained. "From experience, or from every universal remaining in the soul, the principles of art and science arise." The office of experience is "to furnish the principles of every science"703--that is, to evoke them into energy in the mind. 'Experience thus seems to be a thing almost similar to science and art.704In the most general sense, "sensation" would thus appear to be the immediate perception or intuition of facts and principles, and "experience" the operation of the mind upon these facts and principles, elaborating them into scientific form according to its own inherent laws. The "experience" of Aristotle is analogous to the "reflection" of Locke.

So much being premised, we proceed to remark that there is a distinction perpetually recurring in the writings of Aristotle between the elements or first principles of knowledge which are "clearest in their own nature" and those which "are clearest to our perception."705The causes or principles of knowledge "arepriorandmore knownto us in two ways, for what is prior in nature is not the same as that which is prior to us, nor that which is more known (simply in itself) the same as that which is more known to us. Now I call things prior and more known to us, those which arenearer to sense; and thingsprior and more known simply in themselves, those which areremote from sense; and those things are most remote which are especiallyuniversal, and those nearest which aresingular; and these are mutually opposed."706Here we have a distribution of the first or prior elements of knowledge into two fundamentally opposite classes.
(i.)The immediate or intuitive perceptions of sense,
(ii.)The immediate or intuitive apperceptions of pure reason,

Footnote 706:(return)"Post. Analytic," bk. i. ch. ii.
The objects of sense-perception are external, individual, "nearest to sense," and occasionally or contingently present to sense. The objects of the intellect are inward, universal, and the essential property of the soul. They are "remote from sense," "prior by nature;" they are "forms" essentially inherent in the soul previous to experience; and it is the office of experience to bring them forward into the light of consciousness, or, in the language of Aristotle, "to evoke them from potentiality into actuality." And further, from the "prior" and immediate intuitions of sense and intellect, all our secondary, our scientific and practical knowledge is drawn by logical processes.
The Aristotelian distribution of the intellectual faculties corresponds fully to this division of the objects of knowledge. The human intellect is divided by Aristotle into,
1. The Passive or Receptive Intellect (νοῦς παφητικός).--Its office is the reception of sensible impressions or images (Φαντάσµατα) and their retention in the mind (µνήµη). These sensible forms or images are essentially immaterial. "Each sensoriurn (αἰσθητήρων) is receptive of the sensible qualitywithout the matter, and hence when the sensibles themselves are absent, sensations and φαντασίκός remain."707
Footnote 707:(return)"De Anima," bk. iii. ch. ii.
2. The Active or Creative Intellect (νοῦς ποιητικός).--This is the power or faculty which, by its own inherent power, impresses "form" upon the material of thought supplied by sense-perception, exactly as the First Cause combines it, in the universe, with the recipient matter.
"It is necessary," says Aristotle, "that these two modes should be opposed to each other, as matter is opposed to form, and to all that gives form. The receptive reason, which is as matter, becomes all things by receiving their forms. The creative reason gives existence to all things, as light calls color into being. The creative reason transcends the body, being capable of separation from it, and from all things; it is an everlasting existence, incapable of being mingled with matter, or affected by it; prior, and subsequent to the individual mind. The receptive reason is necessary to individual thought, but it is perishable, and by its decay all memory, and therefore individuality, is lost to the higher and immortal reason."708
This "Active or Creative Intellect" is again further subdivided, by Aristotle--
1. TheScientific(έπιστηµονικον) part--the "virtue," faculty, or "habit of principles." He also designates it as the "place of principles," and further defines it as the power "which apprehends those existences whose principles can not be otherwise than they are"--that is, self-evident, immutable, and necessary truths709--theintuitive reason.
2. TheReasoning(λογιστικόν) part--the power by which we draw conclusions from premises, and "contemplate contingent matter"710--thediscursive reason.
The correlativesnoeticanddianoetic, says Hamilton, would afford the best philosophic designation of these two faculties; the knowledge attained by the former is an "intuitive principle"--a truth at first hand; that obtained by the latter is a "demonstrative proposition"--a truth at second hand.
The preceding notices of the psychology of Aristotle will aid us materially in interpreting his remarks "Upon the Method and Habits necessary to the ascertainment of Principles."711

"That it is impossible to have scientific knowledge through demonstration without a knowledge of first immediate principles, has been elucidated before." This being established, heproceeds to explain how that "knowledge of first, immediate principles" is developed in the mind.
1. The knowledge of first principles is attained by theintuition of sense--the immediate perception of external objects, as theexcitingoroccasional causeof their development in the mind.
"Now there appears inherent in all animals an innate power calledsensible perception(αἴσθησις); but sense being inherent, in some animals a permanency of the sensible object is engendered, but in others it is not engendered. Those, therefore, wherein the sensible object does not remain have no knowledge without sensible perception, but others, when they perceive, retain one certain thing in the soul,... with some,reasonis produced from the permanency (of the sensible impression), [as in man], but in others it is not [as in the brute]. From sense, therefore, as we say, memory is produced, and from the repeated remembrance of the same thing we get experience.... From experience, orfrom every universal remaining in the soul--the one besides the many which in all of them isoneand thesame--the principles of art and science arise. If experience is conversant with generation, the principles of art; if with being, the principles of science.... Let us again explain: When one thing without difference abides, there is then the first universal (notion) [developed] in the soul; for the singular indeed is perceived by sense,but sense is [also] of the universal"--that is, the universal is immanent in the sensible object as a property giving it "form." "It is manifest, then, that primary things become necessarily known by induction, for thus sensible perception produces [develops or evokes] theuniversal." 2. The knowledge of first principles is attained by theintuition of pure intellect(νοῦς)--that is, "intellect itself is the principle of science" or, in other words, intellect is theefficient, essential causeof the knowledge of first principles.
"Of those habits which are about intellect by which we ascertain truth,some712are always true, but others713admit the false,as opinion and reasoning. But science and (pure) intellect are always true, and no other kind of knowledge, except intellect [intellectual intuition], is more accurate than science. And since the principles of demonstration are more known, and all science is connected with reason, there could not be a science of principles. But since nothing can be more true than science, except intellect, intellect will belong to principles. From these [considerations] it is evident that, as demonstration is not the principle of demonstration, so neither is science the principle of science. If, then, we have no other true genus (of habit) besides science,intellect will be the principle of science; it will also be the principle (or cause of the knowledge) of the principle."

Footnote 713:(return)The "dianætic."
The doctrine of Aristotle regarding "first principles" may perhaps be summed up as follows: All demonstrative science is based uponuniversals"prior in nature"--that is, uponà priori, self-evident, necessary, and immutable principles. Our knowledge of these "first and immediate principles" is dependent primarily onintellect(νοῦς) or intuitive reason, and secondarily on sense, experience, and induction. Prior to experience, the intellect contains these principles in itself potentially, as "forms," "laws," "habitudes," or "predicaments" of thought; but they can not be "evoked into energy," can not be revealed in consciousness, except on condition of experience, and they can only be scientifically developed by logical abstraction and definition. The ultimate ground of all truth and certainty is thus a mode of our own mind, a subjective necessity of thinking, and truth is not in things, but in our own minds.714"Ultimate knowledge, as well as primary knowledge, the most perfect knowledge which the philosopher can attain, as well as the point from which he starts, is still a proposition. All knowledge seems to be included under two forms--knowledgethatit is so; knowledgewhyit is so. Neither of these can, of course, include the knowledge at which Plato is aiming--knowledge which is correlated with Being--a knowledge, notaboutthings or persons, butofthem."715

ARISTOTELIAN THEOLOGY
Theoretical philosophy, "the science which has truth for its end," is divided by Aristotle into Physics, Mathematics, and Theology, or the First Philosophy, now commonly known as "Metaphysics," because it is beyond or above physics, and is concerned with the primitive ground and cause of all things.716
In the former two we have now no immediate interest, but with Theology, as "the science of the Divine,"717theFirst Moving Cause, which is the source of all other causes, and the original ground of all other things, we are specially concerned, inasmuch as our object is to determine, if possible, whether Greek philosophy exerted any influence upon Christian thought, and has bequeathed any valuable results to the Theology of modern times.
"The Metaphysics" of Aristotle opens by an enumeration of "the principles or causes"718into which all existences can be resolved by philosophical analysis. This enumeration is at present to be regarded as provisional, and in part hypothetical--a verbal generalization of the different principles which seem to be demanded to explain the existence of a thing, or constitute it what it is. These he sets down as--
Footnote 716:(return)"Physics are concerned with things which have a principle of motion in themselves; mathematics speculate on permanent, but not transcendental and self-existent things; and there is another science separate from these two, which treats of that which is immutable and transcendental, if indeed there exists such a substance, as we shall endeavor to show that there does. This transcendental and permanent substance, if it exist at all, must surely be the sphere of thedivine--it must be the first and highest principle. Hence it follows that there are three kinds of speculative science--Physics, Mathematics, and Theology."--"Metaphysics," bk. x. ch. vii.
Footnote 717:(return)"Metaphysics," bk. i. ch. ii.
Footnote 718:(return)Αἴτιον--cause--is here used by Aristotle in the sense of "account of" or "reason why."
1. The Material Cause (τὴν ὕλην καὶ τὸ ὑποκείµενον)--the matter and subject--thatout ofwhich a given thing has been originated. "From the analogy which this principle has to wood or stone, or any actual matter out of which a work of natureor of art is produced, the name 'material' is assigned to this class." It does not always necessarily mean "matter" in the now common use of the term, but "antecedents--that is, principles whose inherence and priority is implied in any existing thing, as, for example, the premises of a syllogism, which are the material cause of the conclusion."719With Aristotle there is, therefore, "matter as an object of sense," and "matter as an object of thought."
2. The Formal Cause (τὴν οὐσίαν καὶ τό τι εἶναι)--the being or abstract essence of a thing--that primary nature on which all its properties depend. To this Aristotle gave the name of εἶδος--the form or exemplaraccording towhich a thing is produced.
3. The Moving or Efficient Cause (ὃθεν ἦ ἆρχη τῆς κινήσεως)--the origin and principle of motion--thatby whicha thing is produced.
4. The Final Cause (τὸ οὗ ἕνεκεν καὶ τὸ ἀγαθόν)--the good end answered by the existence of any thing--that for the sake of which any thing is produced--the ἕνεκα τοῦ, or reason for it.720Thus, for instance, in a house, the wood out of which it is produced is the matter (ὕλη), the idea or conception according to which it is produced isthe form(εἶδος῏῏µορφή), the builder who erects the house is theefficientcause, and the reason for its production, or the end of its existence is thefinalcause.
Footnote 719:(return)Encyclopædia Britannica, article "Aristotle;" "Post. Analytic," bk. ii. ch. xi.
Footnote 720:(return)"Metaphysics," bk. i. ch. iii.
Causes are, therefore, the elements into which the mind resolves its first rough conception of an object. That object is what it is, by reason of the matter out of which it sprang, the moving cause which gave it birth, the idea or form which it realizes, and the end or object which it attains. The knowledge of a thing implies knowing it from these four points of view--that is, knowing its four causes or principles.
These four determinations of being are, on a further and closer analysis, resolved into the fundamental antithesis of MATTER and FORM.
"All things that are produced," says Aristotle,721"are produced from something (that is, frommatter), by something (that is,form), and become something (the totality--τὸ σύνολον);" as, for example, a statue, a plant, a man. To every subject there belongs, therefore, first,matter(ὕλη); secondly,form(µορφή). The synthesis of these two produces and constitutessubstance, or οὐσία. Matter and form are thus the two grand causes or principles whence proceed all things. The formative cause is, at the same time, the moving cause and the final cause; for it is evidently the element of determination which impresses movement upon matter whilst determining it; and it is also the end of being, since being only really exists when it has passed from an indeterminate to a determinate state.
Footnote 721:(return)"Metaphysics," bk. vi. ch. vii.
In proof that the εἶδος or form is anefficientprinciple operating in every object, which makes it, to our conception, what it is, Aristotle brings forward the subject of generation or production.722There are three modes of production--natural, artificial, and automatic. In natural production we discern at once a matter; indeed Nature, in the largest sense, may be defined as "that out of which things are produced." Now the result formed out of this matter or nature is a given substance--a vegetable, a beast, or a man. But what is theproducingcause in each case? Clearly something akin to the result. A man generates a man, a plant produces another plant like to itself. There is, therefore, implied in the resulting thing aproductive forcedistinct from matter, upon which it works. And this is the εἶδος, or form. Let us now consider artificial production. Here again the form is the producing power. And this is in the soul. The art of the physician is the εἶδος, which produces actual health; the plan of the architect is the conception, which produces an actual house. Here, however, a distinction arises. In these artificial productions there is supposed a νόησις and a ποίησις. The νόησις is the previous conception which the architect forms in his own mind; the ποίησις is the actual creation of the house out of the given matter. In this case the conceptionis the moving cause of the production. The form of the statue in the mind of the artist is the motive or cause of the movement by which the statue is produced; and health must be in the thought of the physician before it can become the moving cause of the healing art. Moreover, that which is true of artificial production or change is also true of spontaneous production. For example, a cure may take place by the application of warmth, and this result is accomplished by means of friction. This warmth in the body is either itself a portion of health, or something is consequent upon it which is like itself, which is a portion of health. Evidently this implies the previous presence either of nature or of an artificer. It is also clearly evident that this kind of generating influence (the automatic) should combine with another. There must be a productive power, and there must be something out of which it is produced. In this case, then, there will be a ὕλη and an εἶδος.723

Footnote 723:(return)Maurice's "Ancient Philosophy," pp. 205, 206.
From the above it appears that theefficientcause is regarded by Aristotle as identical with theformalcause. So also thefinalcause--the end for the sake of which any thing exists--can hardly be separated from the perfection of that thing, that is, from its conception or form. The desire for the end gives the first impulse of motion; thus the final cause of any thing becomes identical with the good of that thing. "The moving cause of the house is the builder, but the moving cause of the builder is the end to be attained--that is, the house." From such examples as these it would seem that the determinations of form and end are considered by Aristotle as one, in so far as both are merged in the conception ofactuality; for he regarded the end of every thing to be its completed being--the perfect realization of its idea or form. The only fundamental determinations, therefore, which can not be wholly resolved into each other arematter and form.724
Footnote 724:(return)Schwegler's "History of Philosophy," pp. 120, 123.
The opposition of matter and form, with Aristotle, correspondsto the opposition between the element ofgeneralityand the element ofparticularity. Matter is indeterminate; form is determinate. Matter, abstracted from form, in thought, is entirely without predicate and distinction; form is that which enters into the definition of every subject, and without which it could not be defined. Matter is capable of the widest diversity of forms, but is itself without form. Pure form is, in fact, that which is without matter, or, in other words, it is the pure conception of being. Matter is the necessary condition of the existence of a thing; form is the essence of each thing, that in virtue of which substance is possible, and without which it is inconceivable. On the one side is passivity, possibility of existence, capacity of action; on the other side is activity, actuality, thought. The unity of these two in the realm of determined being constitutes every individual substance. The relation of matter and form, logically apprehended, is thus the relation of POTENTIALITY and ACTUALITY.
This is a further and indeed a most important step in the Aristotelian theology. Matter, as we have seen, after all, amounts to merely capacity for action, and if we can not discover some productive power to develop potentiality into actuality, we look in vain for some explanation of the phenomena around us. The discovery, however, of energy (ἐνέργεια), as a principle of this description, is precisely what we wanted, and a momentary glance at the actual phenomena will show its perfect identity with the εἶδος, or form.725"For instance, what is a calm? It is evenness in the surface of the sea. Here the sea is the subject, that is, the matter incapacity, but the evenness is theenergyor actuality;... energy is thus as form."726The form (or idea) is thus an energy or actuality (ἐνέργεια); the
matter is a capacity or potentiality (δύναµις), requiring the co-operation of the energy to produce a result.These terms, which are first employed by Aristotle in their philosophical signification, are characteristic of his whole system. It is, therefore, important we should grasp their precise philosophical import; and this can only be done by considering them in the strictest relation to each other. It is in this relation they are defined by Aristotle. "Now ἐνέργεια is the existence of a thing not in the sense of its potentially existing. The termpotentiallywe use, for instance, of the statue in the block, and of the half in the whole (since it may be subtracted), and of a person knowing a thing, even when he is not thinking of it, but might be so; whereas ἐνέργεια is the opposite. By applying the various instances our meaning will be plain, and one must not seek a definition in each case, but rather grasp the conception of the analogy as a whole,--that it is as that which builds to that which has a capacity for building; as the waking to the sleeping; as that which sees to that which has sight, but whose eyes are closed; as the definite form to the shapeless matter; as the complete to the unaccomplished. In this contrast, let the ἐνέργεια be set off as forming the one side, and on the other let the potential stand. Things are said to be in ἐνέργεια not always in like manner (except so far as there is an analogy, that as this thing is in this, and related to this, so is that in that, or related to that); for sometimes it impliesmotionas opposed to thecapacity of motion, and sometimescomplete existenceopposed toundeveloped matter".727As the term δύναµις has the double meaning of "possibility of existence" as well as "capacity of action" so there is the double contrast of "action" as opposed to the capacity of action; and "actual existence" opposed to possible existence or potentiality. To express accurately this latter antithesis, Aristotle introduced the term ἐντελέχεια728--entelechy, of which the most natural account is that it is a compound of ἐν τέλει ἔχειν--"being in a state ofperfection."729This term, however, rarely occurs in the "Metaphysics," whilst ἐνέργεια is everywhere employed, not only to express activity as opposed to passivity, but complete existence as opposed to undeveloped matter.
Footnote 725:(return)"That which Aristotle calls 'form' is not to be confounded with what we may perhaps call shape [or figure]; a hand severed from the arm, for instance, has still the outward shape of a hand, but, according to Aristotelian apprehension, it is only a hand now as to matter, and not as to form; an actual hand, a hand as to form, is only that which can do the proper work of a hand."--Schwegler's "History of Philosophy," p. 122.

"In Physics δύναµις answers to the necessary conditions for the existence of any thing before that thing exists. It thus corresponds to ὕλη, both to the πρώτη ὕλη--the first matter, or matter devoid of all qualities, which is capable of becoming any definite substance, as, for example, marble; and also to the ἐσχάτη ὕλη--or matter capable of receiving form, as marble the form of the statue." Marble then exists potentially in the simple elements before it is marble. The statue exists potentially in the marble before it is carved. All objects of thought exist, either purely in potentiality, or purely in actuality, or both in potentiality and in actuality. This division makes an entire chain of all existence. At the one end is matter, the πρώτη ὕλη which has a merely potential existence, which is necessary as a condition, but which having no form and no qualities, is totally incapable of being realized by the mind. At the other end of the chain is pure form, which is not at all matter, the absolute and the unconditioned, the eternal substance and energy without matter (οὐσία ἀίδιος καὶ ἐνέργεια ἄνευ δυνάµεως), who can not be thought as non-existing--the self-existent God. Between these two extremes is the whole row of creatures, which out of potentiality evermore spring into actual being.730

The relation of actuality to potentiality is the subject of an extended and elaborate discussion in book viii., the general results of which may be summed up in the following propositions:
1.The relation of Actuality to Potentiality is as the Perfect to the Imperfect.--The progress from potentiality to actuality is motion or production (κίνησις or γένεσις). But this motion is transitional, and in itself imperfect--it tends towards an end, but does not include the end in itself. But actuality, if it impliesmotion, has an end in itself and for itself; it is a motion desirable for its own sake.731The relation of the potential to the actual Aristotle exhibits by the relation of the unfinished to the finished work, of the unemployed builder to the one at work upon his building, of the seed-corn to the tree, of the man who has the capacity to think, to the man actually engaged in thought.732Potentially the seed-corn is the tree, but the grown-up tree is the actuality; the potential philosopher is he who is not at this moment in a philosophic condition; indeed, every thing is potential which possesses a principle of development, or of change. Actuality or entelechy, on the other hand, indicates theperfect act, the end gained, the completed actual; that activity in which the act and the completeness of the act fall together--as, for example, to see, to think, where the acting and the completed act are one and the same.
2.The Relation of Actuality to Potentiality is a causal Relation.--A thing which is endued with a simple capacity of being may nevertheless not actually exist, and a thing may have a capacity of being and really exist. Since this is the case, there must ensue between non-being and real being some such principle asenergy, in order to account for the transition or change.733Energy has here some analogy to motion, though it must not be confounded with motion. Now you can not predicate either motion or energy of things which are not. The moment energy is added to them they are. This transition from potentiality to actuality must be through the medium of such principles as propension orfree will, because propension or free will possess in themselves the power of originating motion in other things.734

Footnote 734:(return)Ibid., bk. viii. ch. v.
3.The Relation of Actuality and Potentiality is a Relation of Priority.--Actuality, says Aristotle, is prior to potentiality in the order of reason, in the order of substance, and also (though not invariably) in the order of time. The first of all capacities is a capacity of energizing or assuming a state of activity; for example, a man who has the capacity of building is one who isskilled in building, and thus able to use his energy in the art of building.735The primary energizing power must precede that which receives the impression of it, Form being older than Matter. But if you take the case of any particular person or thing, we say that its capacity of being that particular person or thing precedes its being so actually. Yet, though this is the case in each particular thing, there is always a foregone energy presumed in some other thing (as a prior seed, plant, man) to which it owes its existence. One pregnant thought presents itself in the course of the discussion which has a direct bearing upon our subject. Δὑναµιϛ has been previously defined as "a principle of motion or change in another thing in so far forth as it is another thing"736--that is, it is fitted by nature to have motion imparted to it, and to communicate motion to something else. But this motion wants a resting-place. There can be no infinite regression of causes. There is some primary δύναµιϛ presupposed in all others, which is the beginning of change. This is Φύσις, or nature. But the first and original cause of all motion and change still precedes and surpasses nature. The final cause of all potentiality is energy oractuality. The one proposed is prior to the means through which the end is accomplished. A process of actualization, a tendency towards completeness or perfection (τέλοϛ) presupposes an absolute actuality which is at once its beginning and end. "One energy is invariably antecedent to another in time, up to that which is primarily and eternally the Moving Cause."737

And now having laid down these fundamental principles of metaphysical science, as preparatory to Theology, Aristotle proceeds to establish the conception of the Absolute or Divine Spiritas the eternal, immutable Substance, the immaterial Energy, the unchangeable Form of Forms, the first moving Cause.
I.The Ontological Form of Proof.--It is necessary to conceive an eternal and immutable substance--an actuality which is absolute and prior, both logically and chronologically, to allpotentiality; for that which is potential is simply contingent, it may just as easily not be as be; that which exists only in capacity is temporal and corruptible, and may cease to be. Matter we know subsists merely in capacity and passivity, and without the operation of Energy, (ἐνέργεια), or the formative cause, would be to us as non-entity. The phenomena of the world exhibits to us the presence of Energy, and energy presupposes the existence of an eternal substance. Furthermore, matter and potentiality are convertible terms, therefore the primal Energy or Actuality must beimmaterial.738
2.The Cosmological Form of Proof.--It is impossible that there should bemotion, genesis, or a chain of causes, except on the assumption of a first Moving Cause, since that which exists only in capacity can not, of itself energize, and consequently without a principle of motion which is essentially active, we have only a principle of immobility. The principle "ex nihilo nihil" forbids us to assume that motion can arise out of immobility, being out of non-being. "How can matter be put in motion if nothing that subsists in energy exist, and is its cause?" All becoming, therefore, necessarily supposes that which has not become, that which is eternally self-active as the principle and cause of all motion. There is no refuge from the notion that all things are "born of night and nothingness" except in this belief.739

Footnote 739:(return)Ibid., bk. xi. ch. vii., viii.
The existence of an eternal principle subsisting in energy is also demanded to explain theorderof the world. "For how, let me ask, will there prevailorderon the supposition that there is no subsistence of that which is eternal, and which involves a separable existence, and is permanent."740"All things in nature are constituted in the best possible manner."741All things strive after "the good." "The appearance of ends and means in nature is a proof of design."742Now an end or final cause presupposes intelligence,--implies amindto seeand desire it. That which is "fair," "beautiful," "good," an "object of desire," can only be perceived by Mind. The "final cause" must therefore subsist in that which is prior and immovable and eternal; andMindis "that substance which subsists absolutely, and according to energy."743"The First Mover of all things, moves all things without being moved, being an eternal substance and energy; and he moves all things as the object of reason and of desire, or love."744

3.The Moral Form of Proof.--So far as the relation of potentiality and actuality is identical with the relation of matter and form, the argument for the existence of God may be thus presented: The conception of an absolute matter without form, involves the supposition of an absolute form without matter. And since the conception of form resolves itself intomotion,conception,purposeorend, so the Eternal One is the absolute principle of motion (the πρῶτον κινοῦν), the absolute conception or pure intelligence (the pure τί ἦν εἶναι), and the absolute ground, reason, or end of all being. All the other predicates of the First Cause follow from the above principles with logical necessity.
(i.)He is, of course, pure intellect, because he is absolutely immaterial and free from nature. He is active intelligence, because his essence is pure actuality. He is self-contemplating and self-conscious intelligence, because the divine thought can not attain its actuality in any thing extrinsic; it would depend on something else than self--some potential existence for its actualization. Hence the famous definition of the absolute as "the thought of thought" (νόησις νοήσεως).745"And therefore the first and actual perception by mind of Mind itself, doth subsist in this way throughout all eternity."746

Footnote 746:(return)"Metaphysics," bk. xi. ch. ix.
(ii.)He is also essential life. "The principle of life is inherent in the Deity, for the energy or active exercise of mind constitutes life, and God constitutes this energy; and essentialenergy belongs to God as his best and everlasting life. Now our statement is this--that the Deity is a living being that is everlasting and most excellent in nature, so that with the Deity life and duration are uninterrupted and eternal; for this constitutes the essence of God."747
(iii.)Unity belongs to him, since multiplicity implies matter; and the highest idea or form of the world must be absolutely immaterial.748The Divine nature is "devoid of parts and indivisible, for magnitude can not in any way involve this Divine nature; for God imparts motion through infinite duration, and nothing finite--as magnitude is--can be possessed of an infinite capacity."749
(iv.)He is immovable and ever abideth the same; since otherwise he could not be the absolute mover, and the cause of all becoming, if he were subject to change.750God is impassive and unalterable (ἀπαθὴϛ καὶ ὰναλλοίωτον); for all such notions as are involved in passion or alteration are outside the sphere of the Divine existence.751

(v.)He is the ever-blessed God.--"The life of God is of a kind with those highest moods which, with us, last a brief space, it being impossible they should be permanent; whereas, with Him they are permanent, since His ever-present consciousness is pleasure itself. And it is because they are vivid states of consciousness, that waking, and perception, and thought, are the sweetest of all things. Now essential perception is the perception of that which is most excellent,... and the mind perceives itself by participating of its own object of perception; but it is a sort of coalescence of both that, in the Divine Mind, creates a regular identity between the two, so that with God both (the thinker and the thought, the subject and object) are the same. In possession of this prerogative, He subsists in the exercise of energy; and the contemplation of his own perfections is what, to God, must be most agreeable and excellent. This condition of existence, after so excellent a manner, is whatis "so astonishing to us when we examine God's nature, and the more we do so the more wonderful that nature appears to us. The mood of the Divine existence is essential energy, and, as such, it is a life that is most excellent, blessed, and everlasting.752

The theology of Aristotle may be summed up in the following sentences selected from book xi. of his "Metaphysics:"
"This motionless cause of motion is a necessary being; and, by virtue of such necessity, is the all-perfect being. This all-pervading principle penetrates heaven and all nature. It eternally possesses perfect happiness; and its happiness is in action. This primal mover is immaterial; for its essence is in energy. It is pure thought--thought thinking itself--the thought of thought. The activity of pure intelligence--such is the perfect, eternal life of God. This primal cause of change, this absolute perfection, moves the world by the universal desire for the absolute good, by the attraction exercised upon it by the Eternal Mind--the serene energy of Divine Intelligence."
