The general aim of this project is to fundamentally re-think the design of teaching materials in view of what is now known about cognitive deficits and about what Howard Gardner has termed ‘multiple intelligences’. The applicant has implemented this strategy in two distinct areas, the first involving the writing of an English language programme for Chinese speakers, the second involving the construction of specialized equipment for teaching elementary logic to blind students. The next phase (for which funding is sought) is to test the effectiveness of the logic device, because in theory – the one to be tested – materials the design of which is informed by the above rationale will provide a richer learning experience for non-impaired users.

It is uncontroversial that, on any run through a Sorites series, a subject, at some point, switches from an ‘F’ verdict on one exhibit to a non-‘F’ verdict on the next. (Where this ‘cut-off’ point occurs tend to differ from trial to trial.) It is a fallacy to infer that there must be a cut-off point simpliciter between F items and non-F items. The transition is from firm ground to swamp. In the Sorites reasoning, some conditionals of the form ‘If Item n is F, then Item n + 1 is F’ are not false but nonsensical. This solution respects boundarylessness

Romane Clark has complained of the dissimilarity between Sellars’s treatment of conceptual thought and his treatment of sense impressions. For sense impressions are intrinsic to perceptions and, on Sellars’s view, both conceptual thought and perception are species of judgment. In the first section of this paper I want to raise a converse sort of complaint: Sellars offers an ‘adverbial’ theory of sense impressions and a similar account of conceptual thought. But this similarity of treatment is not justified by what Sellars says in its defence. If the adverbial theory of conceptual thought is true, as I believe it is, then a number of consequences, important for the philosophy of action, follow. Sellars traces some of these in his paper “Metaphysics and the Concept of a Person.” It would be desirable, therefore, if the adverbial theory of conceptual thought could be made secure. This is attempted in the second section and, in conclusion, the power of the theory is exhibited by directing it briefly at a long-standing problem in the philosophy of logic.

The author recommends an involved study of logical fallacies in order to provide a database of testable hypotheses for error reasoning. The purpose of the study is to make the study of logical fallacies accessible to a wider audience. Following a recent study conducted by Ludwig Schlecht, the author presents a diagnostic method to illustrate how an argument can be fallacious from the breach of particular rational principles. The diagnosis method also serves as investigation into other forms of argumentative fallacies and the author suggests it could later be the basis for training programs for undergraduate students in logic courses.
