Nelson Goodman and, following him, Catherine Z. Elgin and Keith Lehrer have claimed that sometimes a sample is a symbol that stands for the property it is a sample of. The relation between the sample and the property it stands for is called 'exemplification' (Goodman, Elgin) or 'exemplarisation' (Lehrer). Goodman and Lehrer argue that the notion of exemplification sheds light on central problems in aesthetics and the philosophy of mind. However, while there seems to be a phenomenon to be captured, Goodman's account of exemplification has several flaws. In this paper I will offer an alternative account of exemplification that is inspired by Grice's idea that one can communicate something by providing one's audience with intention-independent evidence and letting them draw the obvious conclusion for themselves. This explication of exemplification will solve the problems that arose for Goodman's theory in the spirit of his approach.1.

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".

Frege’s writings contain arguments for the thesis (i) that a thought expressed by a sentence S is a structured object whose composition pictures the composition of S, and for the thesis (ii) that a thought is an unstructured object. I will argue that Frege’s reasons for both (i) and (ii) are strong. Frege’s explanation of the difference in sense between logically equivalent sentences rests on assumption (i), while Frege’s claim that the same thought can be decomposed differently makes (ii) plausible. Thoughts are supposed to do work that requires that they be structured and work that requires that they be unstructured. But this cannot be! While the standard response to this problem is to reject either (i) or (ii), I propose a charitable repair in the spirit of Frege’s theory that accepts both. The key idea can be found in Frege’s Basic Laws of Arithmetic(BL, GGA). Frege argues that the thought expressed by a sentence is determined by the truth-conditions that can be derived from the semantic axioms for the sentence constituents. The fact that the same axiomatic truth-condition can be derived in different ways from different semantic axioms suggests a Fregean solution of the dilemma: A thought is a type that is instantiated by all sequences of senses (decomposed thoughts) that have the same axiomatic truth-conditions. This allows for multiple decomposability of the same thought (for different decomposed thoughts can have the same axiomatic truth-conditions) and for a notion of containment (the decomposed thought contains those senses whose semantic axioms are needed in the derivation of the truth-conditions). My proposal combines the virtues of (i) and (ii) without inheriting their vices.

In his Foundations of Arithmetic, Frege aims to extend our a priori arithmetical knowledge by answering the question what a natural number is. He rejects conceptual analysis as a method to acquire a priori knowledge . Later he unsuccessfully tried to solve the problems that beset conceptual analysis . If these problems remain unsolved, which rational method can he use to extend our a priori knowledge about numbers? I will argue that his fundamental arithmetical insight that numbers belong to concepts is based on the recognition that different sentences express the same thought. In Frege's philosophy of arithmetic, propositional analysis does the main work. How it can do this work will be discussed in sections 3, 4 and 5. Sections 6 and 7 explore this approach further

Arguments for and against the existence of demonstrative concepts of shades and shapes turn on the assumption that demonstrative concepts must be recognitional capacities. The standard argument for this assumption is based on the widely held view that concepts are those constituents of propositional attitudes that account for an attitude's inferential potential. Only if demonstrative concepts of shades are recognitional capacities, the standard argument goes, can they account for the inferential potential of demonstrative judgements about shades. Shades are conceived as colour universals. Shade a is different from shade b iff it is possible to distinguish a from b visually. In this paper I will argue that the standard argument is based on a mistaken view of inference. We can correctly draw inferences from a demonstrative judgement about something x , even if we are not able to recognise or re-identify the previously demonstrated x during our reasoning. We are prima facie entitled to rely on our preservative memory as retaining our initial demonstrative apprehension of x . The fact that preservative memory entitles us to assume sameness of referent over time is linguistically manifest in the use of anaphoric pronouns: if we can no longer recognise and demonstrate our original demonstratum, we can use anaphoric expressions to pick it up, thereby ensuring sameness of reference. ('That is a nice bird. Now it has vanished. So there is a nice bird that has just vanished.') Since preservation of the initial episode of apprehending x grounds our reasoning from demonstrative judgements, there is no longer a reason to require demonstrative concepts to be recognitional capacities. The standard argument does not get off the ground. 1.

Consider a perceptual activity such as seeing a colour, hearing a tone, tasting a flavour. How are these activities related to one’s awareness of them? I will use Brentano’s struggle with this question to guide the reader through the development of his view on consciousness. My starting point will be Brentano’s book Die Psychologie des Aristoteles (Brentano 1867), in which he developed an inner sense view of consciousness (§§1-2). Brentano’s early view is underexplored in the literature, but crucial for understanding the development of his thought on the matter. In his major work Psychologie vom Empirischen Standpunkt (1874) he rejected the existence of an inner sense: the exercises of our five senses yield awareness of the world (or at least of intentional objects) as well as awareness of these perceptions. This same-level view of consciousness has been explored and developed by contemporary philosophers of mind. I will discuss the arguments that moved Brentano to change his mind, outline the view and, finally, respond to Husserl’s influential criticism of Brentano’s view (§§3-5).

Self-representational theories of consciousness hold that a mental phenomenon is conscious if, and only if, it presents, among other things, itself. But in conscious perception one may lose oneself in the object perceived and not be aware of one’s perceiving. The paper develops a Brentano-inspired response to this objection. He follows Aristotle in holding that one is aware of one’s perceiving only ‘on the side’: when one perceives something one’s perception neither is nor can become observation of itself. I argue that the arguments Brentano gave for this claim in Psychology from an Empirical Standpoint are wanting. However, a promising argument emerges if one takes Brentano’s conception of noticing into account

Does the English demonstrative pronoun 'that' (including complex demonstratives of the form 'that F') have sense and reference? Unlike many other philosophers of language, Frege answers with a resounding 'No'. He held that the bearer of sense and reference is a so-called 'hybrid proper name' (Künne) that contains the demonstrative pronoun and specific circumstances of utterance such as glances and acts of pointing. In this paper I provide arguments for the thesis that demonstratives are hybrid proper names. After outlining why Frege held the hybrid proper name view, I will defend it against recent criticism, and argue that it is superior to views that take demonstrative pronouns to be the bearer of semantic properties

Comment une proposition qui affirme que a est fatigué le matin et n’est pas fatigué le midi peut-elle être vraie ? Bolzano soutient que toute proposition portant sur une chose contingente contient, dans la composante-sujet, la représentation d’un temps. Dans cet article, je reconstruis et évalue les arguments de Bolzano en les comparant à ceux de son adversaire principal, le tenant de la position selon laquelle toute proposition portant sur une chose contingente contient une copule renfermant la représentation du temps auquel l’objet représenté par la composante-sujet a la propriété représentée par la composante-prédicat . La conception bolzanienne de la modification du sujet ne peut résoudre le problème logique de la persistance qu’en assumant que des représentations-sujets qui contiennent différentes représentations de temps représentent différents individus dotés de déterminations temporelles. Mais ceci engendre une nouvelle question : comment un objet peut-il avoir différentes déterminations temporelles sans pour autant changer ?How can we can truly say that a is tired in the morning, and not tired at noon ? Bolzano holds that every proposition about a contingent thing contains an idea representing a time in its subject-part. In this paper I reconstruct and assess Bolzano’s arguments for his view of propositions about contingent things, comparing them to those of his main opponent, the view according to which every proposition about a contingent thing contains a copula combined with an idea that represents a time at which the object represented by the subject-part of the proposition has the property represented by the predicate-part . Bolzano’s subject-modification view could only solve the logical problem of persistence by assuming that subject-ideas containing different ideas of times represent different particulars bearing temporal determinations. But this creates a new question : how can an object have different temporal determinations and yet not change ?

Proper names play an important role in our understanding of linguistic ‘aboutness’ or reference. For instance, the name-bearer relation is a good candidate for the paradigm of the reference relation: it provides us with our initial grip on this relation and controls our thinking about it. For this and other reasons proper names have been at the center of philosophical attention. However, proper names are as controversial as they are conceptually fundamental. Since Kripke’s seminal lectures Naming and Necessity the controversy about proper names has taken the form of a debate between two main camps, descriptivists and non-descriptivists like Kripke himself.The lectures were given in Princeton in 1970 and published in book form as Naming and Necessity .Descriptivists hold that there is a close connection between proper names and definite descriptions: the meaning or sense of a proper name can be given by a definite description.
