    Knowledge Transmission and Linguistic Sense
    Theoria: Revista de Teoría, Historia y Fundamentos de la Ciencia 15 (2): 287-302. 2000.
    Michael Dummett holds that the sense of a natural language proper name is part of its linguistic meaning. I argue that this view sits uncomfortably with Frege's observation that the sense of a natural language proper name varies from speaker to speaker. Moreover, the thesis under discussion is not supported by Frege's views on communication. Recently Richard Heck has tried to develop an argument which is intended to show that assertoric communication with sentences containing proper names is onl…Read more

    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 cru…Read more

    Vacuous Names in Early Analytic Philosophy: Frege, Russell, and Moore
    Philosophy Compass 11 (6): 316-326. 2016.
    Empty proper names give rise to intriguing questions. Frege, Moore and Russell stand at the beginning of analytic philosophy's engagement with these questions. In this paper I will therefore introduce and assess their views on the topic of empty names and draw connections to recent work.

    Semantik Und Ontologie: Beiträge Zur Philosophischen Forschung (edited book)
    Frankfurt: Ontos Verlag. 2004.
    Der zweite Band der Reihe Philosophische Forschung spannt zwei Kerngebiete der Analytischen Philosophie zusammen: die Semantik und die Ontologie. Was sind die Grundbausteine unserer Ontologie? Wie beziehen wir uns sprachlich bzw. geistig auf sie? Diese und weitere Fragen werden von international renommierten Philosophen aus historischer und systematischer Perspektivediskutiert. Die Beiträge sind in Deutsch und English verfasst. Sie stammen von Christian Beyer, Johannes Brandl, Dagfinn Føllesdal,…Read more

    Frege on Judging as Acknowledging the Truth
    Mind 119 (475): 615-655. 2010.
    According to Frege, judgement is the ‘logically primitive activity’. So what is judgement? In his mature work, he characterizes judging as ‘acknowledging the truth’ (‘Anerkennen der Wahrheit’). Frege’s remarks about judging as acknowledging the truth of a thought require further elaboration and development. I will argue that the development that best suits his argumentative purposes takes acknowledging the truth of a thought to be a non-propositional attitude like seeing an object; it is a menta…Read more

    Towards a Neo-Brentanian Theory of Existence
    Philosophers' Imprint 17 1-20. 2017.
    The paper presents an account of the concept of existence that is based on Brentano’s work. In contrast to Frege and Russell, Brentano took ‘exists’ to express a that subsumes objects and explained it with recourse to the non-propositional attitude of acknowledgment. I argue that the core of Brentano’s view can be developed to a defensible alternative to the Frege-Russell view of existence.

    Bolzano's Sententialism
    Grazer Philosophische Studien 53 (1): 181-202. 1997.
    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…Read more

    What is judgement? This question has exercised generations of philosophers. Early analytic philosophers such as Frege, Russell and Wittgenstein as well as phenomenologists such as Brentano, Husserl and Reinach changed how philosophers think about this question. The papers in this book explore and assess their contributions and help us to retrace their steps. In doing so we will get a clearer picture of judgement and the related notion of truth.

    Frege’s Theory of Hybrid Proper Names Extended
    Mind 124 (495): 823-847. 2015.
    According to Frege, neither demonstratives nor indexicals are singular terms; only a demonstrative together with ‘circumstances accompanying its utterance’ has sense and singular reference. While this view seems defensible for demonstratives, where demonstrations serve as non-verbal signs, indexicals, especially pure indexicals like ‘I’, ‘here’, and ‘now’, seem not to be in need of completion by circumstances of utterance. In this paper I argue on the basis of independent reasons that indexicals…Read more

    Does (affirmative) judgement have a logical dual, negative judgement? Whether there is such a logical dualism was hotly debated at the beginning of the twentieth century. Frege argued in ?Negation? (1918/9) that logic can dispense with negative judgement. Frege's arguments shaped the views of later generations of analytic philosophers, but they will not have convinced such opponents as Brentano or Windelband. These philosophers believed in negative judgement for psychological, not logical, reaso…Read more

    Ever since Frege, propositions have played a central role in philosophy of language. Propositions are generally conceived as abstract objects that have truth conditions essentially and fulfill both the role of the meaning of sentences and of the objects or content of propositional attitudes. More recently, the abstract conception of propositions has given rise to serious dissatisfaction among a number of philosophers, who have instead proposed a conception of propositional content based on cogn…Read more

    Frege's concept paradox and the mirroring principle
    Philosophical Quarterly 60 (238): 126-148. 2010.
    Frege held that singular terms can refer only to objects, not to concepts. I argue that the counter-intuitive consequences of this claim ('the concept paradox') arise from Frege's mirroring principle that an incomplete expression can only express an incomplete sense and stand for an incomplete reference. This is not, as is sometimes thought, merely because predicates and singular terms cannot be intersubstituted salva veritate ( congruitate ). The concept paradox, properly understood, poses ther…Read more

    Samples as symbols
    Ratio 21 (3): 344-359. 2008.
    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 capture…Read more

    Proper Names: Philosophical and Linguistic Perspectives
    with Dolf Rami
    Erkenntnis 80 (2): 191-194. 2015.
    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 Namin…Read more

    Knowing the Facts
    Dialectica 65 (1): 75-86. 2011.
    Keith Hossack argues in his The Metaphysics of Knowledge(2007) that knowledge is a simple and metaphysically fundamental relation between a thinker and a fact: knowledge is uptake of fact. Facts are conceived as combinations of particulars and universals, distinct from true propositions. Hossacks's general argument is, roughly, that one can define central philosophical concepts (belief, content, justification, etc.) if one assumes that knowledge is primitive, but that knowledge cannot be defined…Read more
