The world of sense perception therefore, of changing particulars, is not the truly real, but a dim shadowy image, participation of it, only half real, the realm of opinion and not truth.

AristotAristotlele

Aristotle took the word “metaphysics” in several different senses: A first meaning was that metaphysics simply was the science of the suprasensible. However, since, he derived the knowledge of the supra-sensible from the knowledge of sense objects, he arrived at a second meaning of metaphysics: it is the science of the causes of all things, material, formal, efficient and final.

Third conception: science of beingbeing as beingsbeings. Thus the object of metaphysics is all reality visible and invisible: whatever exists. It investigates all realities insofar as they are beings, it tries to dis-cover what belongs to them in their quality of beings.

St. Thomas Aquinas St. Thomas Aquinas

Metaphysics has threefold object: beings as beings, the first principles of beings, and suprasensible beings, especially GOD as cause of all beings.

The immediate object of metaphysics is beings as beings. However, every science must investigate the causes of its object. In the case of beings as beings, these causes may be the extrinsic or intrinsic causes of each particular being: existence and essence, form and matter, EFFICIENT and FINAL causes.

This conception of metaphysics was held by all Scholastic philosophers.

Page 8: History of Metaphysics (Class)

Aristotle’s metaphysics – the study of the real requires the study their causes.4 Causes – Formal – that in a being that makes it to be such, this kind of being; Material – that in a being out of which it is made; Efficient – that which by its action makes a being to be; Final – that for the sake of which something is made or done.

Neo-Platonic Theory of Participation –Where many beings are found to be – intrinsically similar in that they share some one perfection common to all yet are diverse (dissimilar), (1) this common perfection of similarity cannot find its adequate sufficient reason in these many participants precisely as many and diverse.(2) The only adequate sufficient reason for this common sharing must be some one unitary source from which this common perfection derives.(3) What all beings share in common is the act of existence itself. Hence, all beings necessarily point back to one single ultimate source of existence itself.

Page 10: History of Metaphysics (Class)

Thomistic Synthesis: Aristotle’s concern with change, Aquinas transformed into the question of existence: God is both efficient and final cause of all beings. Relation between beings and Being is conceptualized in terms of the Neo-Platonic theory of Participation.

Aquinas existentialized both Aristotle and Plato to show that all beings not only come from God as their First Cause but also return to Him as to their perfect-ion as the Final Cause.

Christian Wolff:

Equated metaphysics with theoretical philosophy, thus considerably widening its object. He distinguished further between general metaphysics and special meta-physics. The former, also called ONTOLOGYONTOLOGY, is the basic philosophical discipline, which investigates being as such (traditional conception of metaphysics).

However, he held that the real task of metaphysics is to deduce, from clearly defined concepts and axioms, the statements which apply to every possible object of thought. In this way, metaphysics no longer is a real study of being, but a mere formal doctrine of axioms or principles. It is no longer rooted in being.

And soAnd so . . . . . .Wolff transformed the very notion of metaphysics. Wolff transformed the very notion of metaphysics.

KANT proceeded beyond both rationalism and empiricism.

Against rationalism, he maintained that universal and necessary principles cannot be merely analytic, that they must be synthetic, if they are to increase our knowledge; in other words, they must not merely explain what we know already, they must add something to our knowledge.But synthetic judgments, which must be universally and necessarily true, cannot derive from sense experience, cannot be, in the sense of empiricism, synthetic judgments a posteriori. Sense experience refers only to the singular and to the contingent.

Kant solved this problem by stating that there must exist judgments which are synthetic a priori, previous to experience, yet yielding really new knowledge.

IMMANUEL IMMANUEL KANTKANT

Thus the problem of the possibility of metaphysics be-comes the problem of the possibility of judgments that are synthetic a priori.

Thus we must turn our attention away from the object to our knowledge of it, or, as Kant put it, “to our way of knowing objects, insofar as this should be possible a priori.”

RECALL:

The problem about the possibility of metaphysics involved the problem of whether or not there exists SYNTHETIC A SYNTHETIC A PRIORIPRIORI (prior to experience yet yielding really new) knowledge.

IMMANUEL IMMANUEL KANTKANT

Thus we must turn our attention away from the object to our knowledge of it, or, as Kant put it, “to our way of knowing objects, insofar as this should be possible a priori.”

Page 15: History of Metaphysics (Class)

This is the turn to the TRANSCENDEN-TAL METHOD. For Kant it meant a pass-age from the conditioned to the condi-tion, from the object of experience to pure reason which determines this object. Thus metaphysics turns into transcen-dental philosophy. It is “pure knowl-edge of reason from mere concepts.” “Metaphysics is a logic of the pure in-tellect.” “It comprises the a priori con-cepts and principles which bring toge-ther the multiplicity of empirical repre-sentations so as to make them into empirical knowledge, into experience.”

Insists that the whole of Western metaphysics has always been interested in beings, not in the being of beings, in the relation of truth of our minds to these beings, truth conceived as conformity of our minds with what these beings are. But it has forgotten something deeper, underlying and rendering possible all such conformity: the very Being of beings, i.e., the ontological shining forth of beings to this consciousness of man, the process of aletheia or passage from concealment to unconcealment, upon which any subsequent relation of conformity must depend as its ground.

Metaphysics, he says, is an ONTIC, not an ONTOLOGICAL, way of thinking because it pays no attention to the ontological difference between beings and being.

A real difference between beings is an ONTIC difference. ONTIC difference refers to the difference between two beings.ONTOLOGICAL: This is the fundamental difference or distinction between beings and Being itself, i.e., Being is not reducible to any of the particular beings in which it is immanent; it transcends each one in its immanent omnipresence.

Heidegger’s summary judgment of Western philosophy may be unfair to some of the greatest thinkers within this tradition, he nevertheless points to real problems and tasks which the methodical reconstruction of metaphysics, on the basis of past experience, cannot afford to ignore. Since the time of Aristotle, classic metaphysics has considered as its object “beings as beings.” This formula mentions only the beings, not the being of beings. But to consider being as beings means to consider in them that which is common to all of them, which makes them into beings, namely, being. The fact that the classic definition mentions only the beings, not their being, as the object of metaphysics, intimates that being as such is never given to us as an object, that it reveals itself to us only in the beings whose ground it is.

No thinker of the past has been more clearly aware of the ontological difference than Thomas Aquinas, nobody has more clearly distinguished between beings (ens) and being (esse), or interpreted beings more consistently in the light of being.
