How much can and should be said about the beginning of Wittgenstein's Philosophical Investigations (PI) on the basis of its very first section alone? Is the only thing worth mentioning that it is designed to introduce the topic for the rest of the book - may this be a "pre-philosophical", "pre-theoretical", "Augustinian" picture of Ianguage (Baker/Hacker, Kenny, Katz, Canfield et al.) or a mentalistic picture of the use of language (Savigny)? These ways of interpreting leave too many aspects of the text untouched. Some of these are: Why does Wittgenstein quote just from the Confessions if his only interest was to get a picture of language? How about Wittgenstein's different ways of dealing with the quotation from Augustine? Trying to answer these questions means to develop a new, more complicated picture o f the beginning of the PI.

An account of predicate reference is presented which attempts to steer a middle course between reductionism, which construes the notion in terms of speakers' inclinations, and {transcendent) realism, which construes the notion in terms of properties. It is first introduced in the context of a discussion of the accounts of length (distance) advanced by Hans Reichenbach, Adolf Grünbaum and Hilary Putnam. A general account of predicate reference is then developed that explains the notion in terms of speakers' inclinations, while rejecting the idea that this explanation should take the form of a reduction. The view is presented as a vindication of extreme nominalism, as it explains predicate reference solely in terms of the notion of qualia introduced by C.I. Lewis and developed by Nelson Goodman, which, it is argued, is definable in terms of speakers' classificatory propensities. Some connections are explored between the position that is presented and the views of Michael Dummett, John McDowell, Mark Johnston and Hilary Putnam, among others.

Wittgenstein uses the word "philosophy" in the Tractatus in three different senses: philosophy as experience (Erlebnis) aiming at solving the problem of the meaning of life and world, philosophy as elucidation (Erläuterung) aiming at determining the nature o f philosophy, clearly demarcating what can be said from what cannot, and philosophy as profession. The latter only consists in the work of analyzing the propositions brought about by philosophy as experience - which cannot be pursued professionally as well as philosophy as elucidation - and in pointing out the nonsensicalness of these propositions.

Meinong's realist theory of measurement is brought up against the presently dominating positivist and operationalist view. His criticism of 19th century positivist analysis of measurement (J. v. Kries) turns out to be pertinent to modern model-theoretic analysis (Suppes and Zinnes). Meinong's ontology of quantities as well as his view of associative and derived measurement is confronted with the operational analysis. The positivist cannot make sense of measurement error and tries to push it aside. In Meinong's view it is pivotal. This view harmonises with the practice of measurement where error is used as a means of gaining knowledge. Starting from Meinong and his pupil Mally a more adequate theory of measurement could be developed.

Donald Davidson has argued against a thesis that is widely shared in the philosophy of language, e.g., by Wittgenstein, Dummett and Kripke: the thesis that successful communication requires that speaker and hearer share a common language. Davidson's arguments, however, are not convincing. Moreover, Davidson's own positive account of communication poses a serious problem: it cannot offer criteria for the correct use of a language, especially in the case of a language that only one speaker speaks. Even though Davidson's own position is not convincing he shows us that the opposite position is weaker than one might assume (compare, e.g., the wittgensteinian idea that a common social praxis of rule-following can supply us with criteria of correctness). Furthermore, the whole discussion shows us that the issue is not settled yet.

Distinguishing sense and referent in true belief that is not knowledge and true belief that is knowledge implies scepticism as regards facts. That is because it falsely reduces knowledge to mere true belief To remove the scepticism, it might be held that sense and referent are the same in both. But this over-correction makes the opposite mistake of reducing mere true belief to knowledge. It also implies either assimilating false belief to true belief or saying, counterintuitively, that the sense of a belief varies with the truth-value of the belief The way out is to take the middle path of distinguishing sense and referent in true belief that is not knowledge and identifying sense and referent in true belief that is knowledge.

We experience evidence, but experienced evidence does not entail objective validity of the evident content. There are different kinds of intuitive evidence: logical and analytical evidence, the presuppositions of realism etc.; there is intuitive evidence in the cognitive field as well as in the practical realm. Intuitive evidence is linked with the basic framework of the respective field. Intuition may be replaced by deeper intuition on the basis of new views that evoke a reconstruction of the framework. Value intuition is characterized as an established opinion which seems undubitable. All persons, all groups and all institutions have actually some practical convictions on which they found their practical evaluation.

It is known that Wittgenstein enjoyed reading Plato; but the significance the philosopher had for him is quite underrated, and has never been properly understood. Utilizing insights by Ortega and E. Havelock, the paper argues that while the background of Plato's philosophy was the emergence of literacy, the genesis and the direction of Wittgenstein's later philosophy, by contrast, is not independent of the emergence of post-literacy (or "secondery orality", to use Walter J. Ong's term). A post-literal phenomenon clearly having specifc impact on Wittgenstein was the film: it is striking that he regularly used the film metaphor to illustrate philosophical points. Analyzing these metaphors the paper reaches the conclusion that according to Wittgenstein the carrier of uncorrupted meaning is, actually, spoken language; if we leave the rein to written language, philosophical problems will arise.

Do all methods of moral justification resemble the method of reflective equilibrium in presupposing that moral judgment's being justified depends at least in part on its being appropriately related to our actual substantial moral views? Can a moral judgment be justified without such a presupposition? I shall distinguish three versions of the no-option argument According to any version of the no-option argument, there is certain fact which characterizes moral theories, and that fact implies that there is no option other than to justify moral judgments by presupposing that their justification depends at least in part on their being appropriately related to our actual substantial moral views. Versions of the no-option argument differ in their specification of the characterizing fact that proves that in ethics there is only one option. I shall argue that the most common versions of the no-option argument are indefensible, while the defensibility of a more sophisticated version depends on the meaning of a notion of moral argument in philosophical ethics.

Bernard Bolzano's most fruitful invention was his method of variation. He used it in defining such fundamental logical concepts as logical consequence, analyticity and probability. The following three puzzles concerning this method of variation seem particularly worth considering, (i) How can we define the range of variation of an idea or the categorial conformity of two ideas without already using the concept of variation? This question was raised by Mark Siebel in his M. A. thesis, (ii) Why must we define analyticity by means of (simultaneous or successive) variation of several ideas rather than by means of replacing a single idea? This problem is suggested by an example due to W.V.O. Quine, John R. Myhill and Benson Mates, (iii) Must every 'there is ...' sentence be synthetic for Bolzano, as his pupil Franz Příhonský claims in his booklet Neuer Anti-Kant, or can a 'there is...' sentence be logically analytic?

In Bolzano's view, a proposition is necessarily true iff it is derivable from true propositions that include no intuition (Anschauung). This analysis is historically important because it displays close similarities to Quine's and Kripke's ideas. Its systematic significance, however, is reduced by the fact that derivability is defined with recourse to the method of variation, which we are allowed to apply even to propositions containing none of the respective variables. This liberality leads to the result that, according to Bolzano's analysis, every truth is necessarily true. Even by introducing his condition of relevance (shared variables), Bolzano cannot avoid that some propositions come out as necessarily true which are merely contingently true.

Bolzano's Sätze an sich and Frege's Gedanken are obviously close relatives. The paper underlines both similarities and dissimilarities between the psychological and semantical roles assigned to structured truth-evaluable contents in Bolzano's and Frege's theories. In particular, their different accounts of propositional identity are compared, and it is argued that Dummett's recent criticism of Frege's account is grist to Bolzano's mill.

Russell, in his History of Western Philosophy, wrote that modern analytical philosophy had its origins in the construction of modern functional analysis by Weierstrass and others. As it turns out, Bolzano, in the first four decades of the nineteenth century, had already made important contributions'to the creation of "Weierstrassian" analysis, some of which were well known to Weierstrass and his circle. In addition, his mathematical research was guided by a methodology which articulated many of the central principles of modern philosophical analysis. That Russell was able to discover philosophical content within mathematical analysis was thus not surprising, for it had been carefully put there in the first place. Bolzano can and should, accordingly, be viewed as a founder of modern analytical philosophy, and not necessarily as an uninfluential one. This paper considers his work in mathematical and philosophical analysis against some of the relevant historical background.

Bernard Bolzano (1781-1848) was an original and independent thinker, who left a lasting legacy in several areas of philosophy. Four such areas are singled for special attention: political philosophy, ethics and theology, logics and semantics, and mathematics. In all these areas he was far ahead of his time. He had pioneering ideas in political philosophy and in ethics and philosophy of religion, and he argued for them in a brilliantly clear way. In logic and semantics he anticipated Frege, Carnap and Quine on important points, and he had intriguing, yet to be explored, ideas on intuition and other fundamental philosophical notions. In the foundations of mathematical analysis and the theory of infinite sets he anticipated Weierstrass and Cantor.

In his Wissenschaftslehre Bernard Bolzano tried to lay down a logically satisfactory foundation of mathematics and theory of probability. Thereby he became aware of the distinction between the actual thoughts and judgments of human beings, their linguistic expressions and the abstract propositions {Sätze an sich) and their components (Vorstellungen an sich). This ontological distinction is fundamental in Bolzano's thinking paired with a universal world view in the sense that philosophy, mathematics, physics and metaphysics should be build upon the same logical foundations. Bolzano's enterprise is sketched in the light of examples from his logical semantics, proof theory, number theory, theory of truth and his variation logic.

The notion of testifying (or testimony) is the central notion of Bolzano's theory of communication. In his Wissenschaftslehre (Theory of Science) Bolzano gives an analysis of this notion. It shows surprising parallels to Paul Grice's attempt to define "A meantNN something by x". I will begin with an explanation of some parts of the analysis and continue with an investigation of the relationship between Bolzano's analysis and that of Grice. In conclusion I would like to present some evidence supporting the hypothesis that several of the virtues of Grice's theory had already been developed by Bolzano, whose approach even has the advantage of a better definition than Grice's, as Bolzano's analysis provides a better basis for defining a notion of successful communication of information.

Bolzano holds that every sentence can be paraphrased into a sentence of the form "A has b". Bolzano's arguments for this claim are reconstructed and discussed. Since they crucially rely on Bolzano's notion of paraphrase, this notion is investigated in detail. Bolzano has usually been taken to require that in a correct paraphrase the sentence to be paraphrased and the paraphrasing sentence express the same proposition. In view of Bolzano's texts and systematical considerations this interpretation is rejected: Bolzano only holds that the sentence to be paraphrased and the paraphrasing sentence must be equipollent ("gleichgeltend"). It is shown that even this modest view of paraphrase does not help Bolzano in sustaining his claim that all sentences have the form "A has b".

Analytical philosophy begins with the first mathematical and philosophical works of Bolzano published between 1804 and 1817. There, Bolzano set out a project for the global reform of mathematics by means of the axiomatic method. Having completed the Wissenschaftslehre, Bolzano wrote a summary of his logic for the Größenlehre, which he sent to Exner in 1833. The correspondence between Bolzano and Exner covered some of the main subjects treated by analytical philosophy: the status of abstract objects (propositions and objective ideas), intuitions, objectless ideas, the concept of object and many others. While Bolzano argued in favor of abstract entities independent of mind and of language, Exner considered them as abstractions obtained from the subjective judgments and representations. During the XlXth century, Bolzano's philosophy spread over Bohemia and Austria through manuscripts and through the first edition of Zimmermann's textbook of philosophy. The most important Brentanians, Kerry, Twardowski, Meinong and Husserl, discussed his doctrines which may also have influenced Wittgenstein and the Polish school.
