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)
Here are crucial data for any theory of the self, self-consciousness or the structure of experience. We discuss the fundamental structure of both indexical reference, especially first-term reference, and quasi-indexical reference, used in attributing first-person reference to others. Chisholm's ingenious account of direct awareness of self is tested against the two sets of data. It satisfies neither. Chisholm's definitions raise serious questions both about philosophical methodology and about the underlying ontology of individuation, identity, and predication. Chisholm's adverbial account of non-physical (...) contents of consciousness is also examined; several questions are raised about the possible success of the linguistic technique of ontological reduction by hyphenation and creation of grammatical devices.

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)
This is a multifaceted semantico-ontological investigation of different types of families of concepts and properties. One major result is that contrast between: (a) the ontologically egalitarian or democratic, but epistemologically hierarchical family of colors, and (b) the ontologically hierarchical or pyramidal familiy of negations. The different negations (of propositions, imperatives, properties, predication) are studied, and the unity of the whole family under a genus reveals the pyramidal structure of the family. The negation or properties has a powerful bearing on Russell’s (...) paradox -- which shows different strands in negation. The connections between existence and negation provides an introduction to Guise Theory and reveals some limitations in Bertrand Russell’s analysis of definite descriptions. (shrink)
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.
