This paper examines a number of river images which have been attributed to Heraclitus, the ways they are used by Plato and Wittgenstein, and the connection between these uses of imagery and the metaphilosophical issues about the nature and limits of philosophy which they lead to. After indicating some of the connections between Heraclitus’, Plato’s and Wittgenstein’s use of river images, I give a preliminary reading of three crucial fragments from the Heraclitean corpus, associating each with a different river image. Each of these images implies an overall conception of the nature of change and continuity and of the relationship between language and world. I then turn to the use of these images by Plato and Wittgenstein, and explore the relationship between their uses of river imagery and their conceptions of philosophy. To put it slightly differently, this paper is about Plato’s and Wittgenstein’s use of certain Heraclitean ideas.

The model of memory as a store, from which records can be retrieved, is taken for granted by many contemporary researchers. On this view, memories are stored by memory traces, which represent the original event and provide a causal link between that episode and one's ability to remember it. I argue that this seemingly plausible model leads to an unacceptable conception of the relationship between mind and brain, and that a non‐representational, connectionist, model offers a promising alternative. I also offer a new reading of Wittgenstein's paradoxical remarks about thought and brain processes: as a critique of the cognitivist thesis that information stored in the brain has a linguistic structure and a particular location. On this reading, Wittgenstein's criticism foreshadows some of the most promising contemporary work on connectionist models of neural functioning.

Wittgenstein's middle period work has been brought into the current debate on rule following and representation by Kripke and the Hintikkas. In my dissertation, I argue that approaches which aim at a consistent reconstruction of Wittgenstein's argument, while valuable in their own right, fail to do justice to his focus on the conflicting intuitions that lie behind philosophical theory building. For this hidden and ambiguous side to his thought is the turning point in his philosophical development. ;One can summarise my findings as follows: In 1929, Wittgenstein recognised that the analysis of colour propositions forced him to give up the Tractarian doctrine that analysis must end in logically independent elementary propositions. From this point, his work branched out in two main directions. On the one hand, he worked on 'philosophical grammar': analyses of the rules we follow in talking about such matters as colour, visual experience, intention, time, memory and the philosophical subject. Here, the picture theory provided the basis for an account of how the mind represents the world. On the other hand, he also thought of language as a 'secondary' system, to be contrasted with direct apprehension of the 'primary' phenomena. This view, which is set out most fully in several chapters of an unpublished typescript , led to a seemingly inexpressible solipsism on which 'all is in flux.' The attempt to reconcile the two conceptions of the pictorial analogy--language as a system of representational conventions and experience as a direct presentation of the phenomena--ultimately led him to see the dangers in that analogy and thus to his later notion of a 'philosophical picture.'.

Ludwig Wittgenstein's treatment of private language has received more attention than any other aspect of his philosophy. Yet, for more than fifty years, a remarkably self-contained exegetical tradition has defined the terms of debate and the principal positions that are discussed. Orthodox interpreters hold that the proof that a private language is impossible turns on showing it is ruled out by some set of systematic philosophical commitments about logic, meaning, and knowledge. Leading candidates for this ground on which the argument depends have included the analysis of concepts, the grammar of our everyday language, the logic of criteria, or the nature of our rule-following, practical activity, or form of life. This article introduces an alternative interpretive tradition, which not only rejects the orthodox methodology, but also rejects the presupposition that Wittgenstein's principal aim is to provide a deductive proof that the idea of a private language leads to contradiction. Finally, it examines some of the leading readings of Philosophical Investigations §258, the passage most frequently discussed by orthodox interpreters.
