Abstract

Ever since Aristotle, ontology has been assumed to have a single meaning. Classic ontology branched into three directions established by Kant--the three chief manifestations of reality: cosmology, psychology, and theology--and in its quality of pure ontology became the study exclusively of being. On the other hand, the three dialectical branches have been losing their validity and are being replaced by regional ontologies which take explicit account of their several objects. Four territories today present themselves for intensive speculative cultivation; quantity, matter, life, and spirit. Theology has returned to its classic position at the side of pure ontology. The ideas of object and of concept are radically opposite, but nevertheless are closely related in the context of knowledge; an object is the source of a concept. A concept is formed by one or several objective instances, but does not include all of them; there are more or less determinate objects, some of which have undergone conceptual modification while others remain quite obscure, all of which indicates that the world of reality is not so evident or firm as it appears to common sense. The ideas of being and of objects bring us again to the consideration of the metaphysical theme of the individual. Neither being nor object is the concrete individual; the problem of the individual remains involved in the whole problem of substance as it was discussed in classic metaphysics, because it was completely grounded in this metaphysics and is best discussed and appreciated as the problem of the incommunicable and subsistent. Regional ontology, in fixing its attention entirely on the object, thereby limits itself and makes clear its methodological orientation. Regional ontology by no means is to be considered as a theory of science; any theory, concrete or general is subject to a synthetic process in which facts and proofs immediately given incorporate the theory into the patrimony and positive achievements of intelligence. A theory is a scientific synthesis, and although its fundamental role is logical, its origin implies experimental functions. Regional ontology can be considered as a theory of objects, but its validation does not come from science itself; rather, it is the validation of scientific facts. Ontology might be called a theory a priori, but in that case the terms "theory" and "a priori" would be contradictory since the former requires experience and the latter renounces all experimental data. Ontology operates by means of general essences which objects of the same denomination have in common; thus we speak of the realm of quantity, the realm of matter, the realm of life, and the realm of spirit. The mathematical as well as the natural, biological, and spiritual sciences clearly have different objective planes which correspond to different ontological categories, which are foreign to the experiencing subject because it knows them only concretely as phenomena. The metaphysical basis of mathematics is quantity, a real accident of matter. Quantity examined according to the ontology of mathematics arises from matter, finding its origin in matter as the quality related to form. The ontology of the physicochemical sciences is concerned with the contents of quantity, with the internal object by which quantity is numbered and given its nature. Matter presents a problem to philosophy no less important than the problem it presents to the sciences whose data are mere approximations to matter. Natural sciences which seem very intelligible resolve themselves into a morass of questions when one tries to reduce them to science strictly so-called. In present-day philosophy we say that the nature and structure of objects and beings, both inorganic and organic, are in practice external to human action, taking "human" in the sense of spiritual being. The instability of living being, in contrast to the internal equilibrium of inanimate being, makes it appear less intelligible. On the plane of ontology of life, man is the central problem, even though he is one of the most definite and individualized of beings. Man's life culminates in freedom, which makes man a responsible being, in this respect resembling God. Though less unknown than mathematical, material, and biological objects, mental objects are more difficult and involve subtle and risky problems. The first great phenomenon offered to the philosophy which penetrates the field of the ontology of the social sciences is the identity between the object and the subject, since the subject, who as far as possible refers systematically to the pure object, continually treads the boundary of reality and arrives at himself; that is, the inquiring subject becomes simultaneously the object investigated--a kind of cognitive identity possible in reflection. The second problem of this field of philosophy is the consideration of "I" as absolutely empty of objectivity. For contemporary philosophy, spirit is the world of values, and it is not so important to determine the pure reality of spirit as to understand its life, its activity, and its specific manifestation which is the world of culture. The social sciences deal with man as a spiritual being, and with the facts of culture. The values produced by culture constitute a hierarchy which goes from the most humble to the most elevated, from plain economic interest to an intense desire for God. Culture is produced by the objectification of values; spirit becomes fixed in certain entities which are cultural objects: a theory, a machine, a concert. Man acts as the creator of a culture, but the culture in turn spiritually actuates and nourishes him. The sciences of spirit go from signs to their meaning, from the expression to the living. The point of departure in historical knowledge is our own vital experience, the very life which flows within us. Only life understands life. Here we find the reason why culture indicates the maximum expression of life; in culture, man contemplates himself, and in himself he contemplates all the beings of creation.
