The following relation between operations F and G is called an adjoint situation or adjunction, and such a relation occurs almost everywhere in logic and mathematics; F(C)→B ⇔ C→G(B). The relation between A∧ and A⊃ which are primitive connectives in logic is a well-known example. So to understand the primitiveness of these connectives, it is necessary to clarify the essence of adjointness. For this purpose the author thinks tentatively that two operations G and F in an adjunction ultimately correspond to two mental functions (i.e. projection and reflexion) which are always found in a primitive state of our consciousness.

This paper is an examination of Jerry Fodor's internalist position in his controversy with externalists. His internalism is not to be taken as the contention that the whole of mental content is independent of the surrounding world. Rather his point is that the scientific explanation of behavior requires that the relevant mental content should be causally efficacious and therefore supervene on brain states. If we have to give the content of a propositional attitude a semantic value, we can interpret "narrow contents" as functions from both their contexts and mental states to "wide contents".

The aim of this paper is to propound a view that philosophical epistemology has failed to comprehend the essence of experimental natural science ever since the late seven-teenth century. The first indication of the failure is given in Edward Stillingfleet's misunderstanding of John Locke. In his Essay concerning Human Understanding, Locke tries to establish the distinction between the particular matters of fact and the universal theories of nature. Stillingfleet mistakenly counts him, however, among cartesians and regards his distinction as that of the objects in the mind and those in the external world. This misreading of Locke, which is common to later historians of philosophy, entails total misunderstanding of the essential trait of experimental science. The Lockean way of ideas is, if correctly un-derstood, a successful vindication of the experiments based on sense perception and has nothing to do with the cartesian skepticism towards the senses.

Scientific methodologies in 17-18th centuries are very important when we think of the relation of philosophy and science in this period. Particularly interesting among them is that of Leibniz's philosophy. His method of finding laws of natural sciences was a so-called hypotheticodeductive method. What is quite remarkable in his methodology is that he not only shows empirically valid criteria for finding laws, in spite of his extreme rationalistic tendencies on one hand, but also delves into the grounds for the hypothetico-deductive method in terms of God's perfection. In this latter point, we can recognize one of the proper roles of philosophy, very clearly distinguished from but united very organistically with those of science.

I attempt in this paper to survey the classical features which lie in the concept and methodology of the Newtonian science. To this end I summarize the concept of science in the Aristotelian philosophy, and utilize several recent results in the Newtonian scholarship.

In this paper I show an aporia which both a subjectivist view and a functionalist view of qualia have in common, and try to change the view of qualia in order to solve the aporia. The aporia of the qualia problem is this: as long as we take a subjectivist view or a functionalist view, qualia must shift either into something other than qualia, or just into nothing. A solution of the aporia which I try to present is: qualia is neither something nor nothing, but an uncom-pleted absence.

Cybernetics first introduced by Norbert Wiener in 1940's has been inter- or meta-disciplinary science and this has been one of the most attractive and fruitful aspects of the cybernetics community. In this kind of community many new ideas have been emerged. Here two major conceptual developments of cybernetics would be pointed and discussed. One is the line from self-regulation to self-organization, autopoiesis, and self-reference, and the other is the line from first-order cybernetics to second-order cybernetics. Finally the potentiality of cybernetics to open the door to the new era in the area of medicine and psychotherapy would be discussed with a few brief examples.

Lukasiewicz-type completeness proof of classical propositional logic is presented coupled with the axiomatic rejection for the logic. This is to the effect of much simplifying the completeness proof. On the basis of the consistency of the logic the cut-elimination theorem in the sense of Gentzen is also demonstrated of the logic making use of the axiomatic rejection.

Axiomatic rejection for Aristotle's syllogistic is not fully arranged as a formal system because one of its rejection rules contains a meta-concept. In this paper, we restrict our discussion to the classical propositional logic and reconstruct the rejection system as a formal system with assumptions. Furthermore, we give the axiomatization of satisfiability through a similar way of the reconstruction of the rejection system.

In this note I examine the criticism of Quine's "Two Dogmas" given by Crispin Wright in his "Inventing Logical Necessity". Wright claims, in opposition to Quine, that certain metalogical statements are indeed immune to revision. Without committing myself to Quine's position, I show that Wright's argument is flawed since (1) he overlooks the indispensable role of intuitive reasoning in metalogic, and (2) even if the acceptance of a metalogical statement is presupposed in the test of a certain theory, it does not follow that the very same metalogical statement must be presupposed whenever we put a theory into empirical test.

This paper proposes to provide a general view of Duhem's epistemological thought, which is now well-known perhaps only for so called Duhem-Quine thesis.This holistic idea on the 'structure' of the scientific activities is, in Duhem's real work, accompanied by the representationistic idea on the 'aim' of the same activities, and forms with it a total rejection of two dogmatisms, that is, physical realism and empiricism. But although destructive with regard to these dogmatisms, neither holism nor representationism succumbs to skeptic relinquishment. It is the cogency of the scientific history that saves them from stranding in skeptic despair, as well as reinvigorating themselves in dogmatic ambition.

Duhem-Quine thesis that a single theory can never be tested and decisively refuted by experience is well known among philosophers of science. But Duhem himself did not argue for that thesis. His argument was restricted within physical theories.Duhem has been interpreted as an instrumentalist or conventionalist. But he did not deny the existence of a reality behind the theory. Duhem's realism is very different from contemporary scientific realism. To understand his philosophy of science, it is important to note that he was a Pascalian and argued for intuition as well as logic. His philospophy of science is similar to that of M. Polanyi.

The science of chaos, as a new breed of science, has many features which are not common among modern studies in science. Its subject, chaos, has no clear definition, but its mathematical 'paradigms', i.e. some nonlinear equations, whose solutions share unique intricate patterns, seem to be in many ways revealing hitherto unexpected aspects both of the world and of many researches into it. It is examined in this paper what constitutes the ontological status of mathematical models which would be necessary for the unconditional acceptance of these aspects as genuine ones. The likely physical meaning of nonlinearity, and what it might enable one to explain are also envisaged.

The philosophical implications of "chaos" cannot be grasped without clear understanding of such concepts as "determinism", "non-linearity", and "predictability". Beginning with Laplace's classical statement of determinism and predictability, I will sketch Maxwell's and Poincaré's modifications of the statement and their awareness of the significance of nonlinearity. Then I will briefly touch upon what may be suggested by the study of chaos for clarification of the notion of complexity; and, finally, contend that the computation for the study of chaos can be regarded as a kind of inductive basis, which provides the affinity of mathematics and natural sciences, on the one hand, and the continuity of traditional sciences and studies on chaotic systems, on the other.
