Wittgenstein's discussion of rule-following can be considered as a part of his criticism of metaphysics: Naturalistic as well as non-naturalistic ontologies fail to present us an adequate explanation of the normative dimension of linguistic behavior. In this paper, we will reconstruct this criticism of metaphysics and show that thereby we gain an important philosophical insight: Wittgenstein's criticism implies that the normativity of language is not a phenomenon that stands in need for an explanation but rather – to the contrary – (...) has to be considered as a primitive, non-reducible condition that we have to presuppose in order to show how linguistic meaning is possible at all. In this sense, the notion of rule-following gives rise to a transcendental semantics. (shrink)

Moral Relativism can be considered an attractive alternative to realism because relativists can make good sense of cultural and societal disagreements by seeing them as faultless. However, we can show that this advantage is made possible by systematically disagreeing with moral phenomenology. Relativists make a substantial distinction between intercultural and intracultural discourses which turns out to be incoherent. This can be shown by making use of Crispin Wright’s notion of Cognitive Command.

Whether there are philosophically relevant connections between the expressive role of first-personal vocabulary and self-knowledge is an on-going debate in analytical philosophy. We will take a look at this debate by considering Ludwig Wittgenstein’s distinction between the two uses of ‘I’ as object and as subject and work out a further distinction within the subject-use of ‘I’. This relates to a problem that is inherent in Robert Brandom’s inferentialist program regarding the role of first-personal vocabulary. It can be shown that (...) subject-related aspects of language are necessary elements of inferentially articulated discourses—and not, like Brandom assumes, merely contingent features. (shrink)

During the last century of meta-ethical debates, moral realism was much criticized for its ontological assumptions. These assumptions arise from the semantic intuition that lies at the heart of realist theories – namely, the intuition that language represents states of affairs. This makes moral realism hardly compatible with a naturalist world view and gives rise to consider ontologically more economic approaches. Moral constructivists can explain objectivity in ethics without inheriting the realist’s ontological burden. Nevertheless, constructivists tend to ignore the semantic (...) task of giving an account of what moral sentences mean. The semantics of moral discourse, however, cannot be considered representational because, then, constructivism would lapse back into realism. I argue that semantic pragmatism is an appropriate partner for moral constructivism. Thereby, we can see the personal standpoint as an engagement in asserting moral sentences. (shrink)

One branch of practical philosophy in whichWittgenstein’s writings might be fruitful, is political philosophy. The concept “forms of life” gives rise to a pluralistic interpretation of society. However, the question arises how societal conflicts in such a pluralistic view con be solved. We will develop a method of criticism which relies on Wittgenstein’s later work and which combines the normative demands of practical philosophy with methodological standards from ethnology and cultural anthropology.

One of the basic notions of ethics is certainly the concept of the will. Although in his Tractatus Logico-Philosophicus, Wittgenstein excludes that ethical sentences can be meaningfully formulated, the conception of the will occupies a prominent position in his book. This supposed tension in the Tractatus is not accidental, but an integral part of Wittgenstein's concern to reach a new, non-philosophical approach towards ethics.

Are persons rational because they are self-conscious or are they self-conscious because they are rational? Wittgenstein's remarks on the grammatical peculiarities of first-person expressions are not only a criticism of the conception of a Cartesian Ego but also give rise to systematical extensions which help to answer our question. The distinction between subject- and object-usage of ,,I” – which is made in the ,,Blue Book” – enables Wittgenstein to conceive of sentences like ,,I am in pain” as non-referential expressions. With (...) this distinction, Wittgenstein criticizes the ontological commitment to an Ego which results from the referential usage of ,,I”. Nevertheless, Wittgenstein's distinction stands in need of an addition: We will distinguish an epistemic form of expression from a phenomenal form. On this basis, we can show that self-consciousness systematically builds on rationality – and not the other way around. Competent usage of epistemic-expressive I-sentences is antecedent to talking meaningfully of a self-conscious person. In turn, the competent usage of such sentences is embedded in a social structure. Self-consciousness has a social place. (shrink)
