We have now provided an overall simple theoretical account of the structure of perceptual experience proto-philosophically examined in Part I. The next task is to find the proper logical machinery to formulatte those accounts rigorously.
This is an investigation into the fundamental connections between the referential use of language and our rich human experience. All types of experience — perceptual, practical, scientific, literary, esthetic, ludic, ... — are tightly unified into one total experience by the structure of reference to real or possible items. Singular reference is essential for locating ourselves in our own corner of the world. General reference, by means of quantifiers, is our main tool in ascertaining the accessible patterns of the world. (...) Both are primitive and mutually irreducible. (Often this has been denied.) The unity of total experience is constructed through the biographical unity of a person, and the sociological unity of the communications across a community. This unity of experience is wrought out by an underlying unitary system of reference. We need, therefore, a comprehensive theory of individuation, existence, predication, and truth. One such a theory is Guise Theory. (shrink)
I am pleased to have been able to vindicate Plato from the oft-rehearsed charge of not having distinguished relations from qualities. Not only does Phaedo 102B7-C4 show quite clearly that he did make the proper distinction, but the theory of relations he adumbrated there is logically sound and ontologically viable. Furthermore, it is refreshing to think of relations not as Forms or universals, but as chains of ontologically tied universals.Naturally, now that we have a clear understanding of Plato's Phaedo theory (...) of relations and relational facts there is plenty of work to do. We must examine the other dialogues for alterations or even preservation of that theory. Moreover, there are those arguments of Aristotle that purport to reduce Plato's Theory of Forms to absurdity on account of relations. But of this I shall say more at some other time. (shrink)
For quite a long time now I have argued against the view, widely held, and forcefully expounded by John Burnet, that at Phaedo 102b2-d2 Plato is formulating the notion of essential attribute and contrasting essence with accident. I have claimed that the essence-accident contrast is absent from that passage. This is a view that others have also held. But I have since 1950 found in that passage a formidable theory of relations. Recently, Professor David Gallop has taken me to task (...) for my heterodoxy. His reaction is overwhelming:I confess that I do not see how such a theory, [A] even if the text were to embody it, [B] could be held to provide an adequate account of relational statements in general. Gallop's paper is very tantalizing. Although he establishes neither A nor B, he does offer a series of very extraordinary arguments, whose examination reveals the depth of Plato's thinking on relations. (shrink)
The problems of referential opacity in psychological contexts require a solution, of which three types are indicated, that contains a profound theory of predication, identity, and individuation. a radical theory, not in the spirit of the current fashions, is outlined. it is called the guise-consubstantiation, conflation, and consociation theory. this theory was first expounded in "thinking and the structure of the world," "philosophia" (1974) and "critica" (1972). the present paper is an introduction to this essay, motivated by two criticisms of (...) romane clark in "not every object of thought has being," "nous" (1978). it is shown that clark's arguments rest on equivocations, one involving the data and the theory, and the other within the theory itself. thus, a discussion of philosophical method turns out to be crucial, and an analysis of expression 'true of' is offered.

I have shown (to my satisfaction) that Leibniz's final attempt at a generalized syllogistico-propositional calculus in the Generales Inquisitiones was pretty successful. The calculus includes the truth-table semantics for the propositional calculus. It contains an unorthodox view of conjunction. It offers a plethora of very important logical principles. These deserve to be called a set of fundamentals of logical form. Aside from some imprecisions and redundancies the system is a good systematization of propositional logic, its semantics, and a correct account (...) of general syllogistics. For 1686 it was quite an accomplishment. It is a pity that Leibniz himself did not fully appreciate what he had achieved. It does seem to me that this was due in part, as the Kneales urge (Note 4), to his having kept the focus of his attention on traditional syllogistics. It is a great pity that he did not polish GI 195–200 for publication. The publication of GI 195, 198, and 200 would have most likely promoted further research.
