Professor Prawitz has made four claims in his talk. The first claim is that one should be able to generalize the intuitionistic theory of meaning already available for mathematical discourse to empirical discourse. Since each claim constitutes a step in an argument of a general form in favour of some new kind of antirealistically inclined theory of meaning (with a final pessimistic overtone), I shall go over each claim one by one, check whether the argument which links them in the way described is sound, and assess on that basis the appropriateness of the project (and of the pessimism)

Modernism, in the book under review, is characterized as the belief that "there can be no philosophical language; that the kind of truth sub specie aeterni that was sought by philosophers is either meaningless or more appropriately expressed by the arts -- especially by literature and poetry" (p. xiii). The author wishes to show that this thesis rests upon unquestioned dogmas, presuppositions or presumptions "regarding the distinction between representation and presentation," which should be rejected (p. 9). She proposes to criticize the distinction, along with the other unwarranted distinctions thereby embedded in the central tenet of modernism, and to overcome the "modernist overcoming of metaphysics" by drawing on the works of Jacques Derrida and Michael Dummett.

In a nutshell, semantic antirealism is the doctrine that if a statement is true, then it must be possible, at least in principle, to determine that it is true. Consider the particular case of self-ascriptions of attitudes such as beliefs, desires and intentions, i.e. statements of the form "I φ [that] p", where φ ranges over propositional attitude verbs and p provides the content of whatever is φd by the self-ascriber. Should we be semantic antirealists about these when the putative bearer of the attitude is the only individual who may retrieve a warrant in favour of his φing that p? We can't provide an answer to the question unless we're clear about (i) whether or not the "at least in principle" clause is too weak, and (ii) what the right construal of positive introspection should look like. 2 Thus two issues: strict finitism on the one hand and the phenomenological nature of introspective warrants on the other. I shall argue that recent views defended by Peacocke and Pryor are found wanting with respect to both

Emotions are part of our culture ; particular emotions like resentment andguilt are part of specific cultural heritages. On the other hand, moral judgementsand imperatives have the appearance of objectivity. There lies - or so it seems -a conflict, even a contradiction. Statements like "Slavery is unjust" may beasserted, agreements may be reached concerning what they claim or express,and they may occur as antecedents in conditionals such as "If slavery is unjust,then it must be abolished". When it is claimed that slavery is unjust or that it iswrong to harm others, it is thereby claimed that it is so objectively. We mean bythis (among other things) that it is so independently of the moral emotionsanyone may feel with respect to slavery or the infliction of pain.It will be argued here that there are grounds to believe that emotions must beevaluated cognitively and that they do have cognitive significance, value andcontent. In this cognitive or quasi-cognitive perspective, the appropriatecharacter of an emotion is akin to the truth of a proposition : just as the truth of aproposition may be evaluated in terms of the justifications we are able toprovide in its favour, the correctness of emotions may be evaluated relatively tocognitive bases and classes of available warrants. Some emotions may be ruledout as incorrect or inapproriate, just as some propositions may be rejected asunjustified or in need of a warrant. The parallel relies on the controversial notionof non-propositional forms of moral justification. The notion may be construedin a variety of ways, the most promising construals being, I believe, thoseprovided by the perceptual model.I shall focus on the following point. Moral judgements and imperatives areexpressed with the usual resources of natural languages. These typically includepredicates like "unjust" and "wrong", and deontic sentential operators like"must" and "should". Moral emotions, on the other hand, may be expressed bybodily movements and facial expressions. Although it may be argued thatemotions do not bear the cognitive marks of objectivity when expressed in thisway, there is no reason to think that a reformed language of ethics, i.e. a purelanguage of emotions, free of all the linguistic or symbolic marks of truth,assertability and objectivity, would thereby be free of normative input, or evenbe inadequate to express normative claims. I shall argue that once nonpropositionalforms of justifications are taken into account, the reformingstrategy of emotivists and neo-emotivists is indeed ineffective

Although G¨odel proved the first incompleteness theorem by intuitionistically respectable means, G¨odel’s formula, true although undecidable,seems to offer a counter-example to the general constructivist or anti-realistclaim that truth may not transcend recognizability in principle. It is arguedhere that our understanding of the formula consists in a knowledge of itstruth-conditions, that it is true in a minimal sense and, finally, that it is recognized as such given the consistencyand ω-consistency of P. The philosophical lesson to be drawn from G¨odel’sproof is that our capacities for justification in favour of minimal truth exceedwhat is strictly speaking formally provable in P by means of an algorithm

According to the antirealist view of history, history is something historians construct in the present. Although the warrants they may gather in favour of past events do not form a coherent class, such warrants constitute the assertibility conditions of our statements about the past. They are by nature partial, gradual and defeasible. The antirealist is then faced with two problems. One is to account for a notion of historical significance, either in terms of causal links, broad patterns, or justified historiographic generalizations. A second one is to secure a bound to the holistic construal of historical cognitive content. A coherent antirealist about history must explain why historical claims are in the market for truth, without taking the position of an ideal observer looking at the past from an a-historical fixed point outside time

There are several ways of conceiving objectivity -- scientific objectivity in particular -- and, accordingly, several ways of defending or attacking particular construals of it. According to one conception sometimes labelled "realism", objectivity in science is a semantic, modal and metaphysical notion: a scientific theory is objective insofar as it tells the truth about the way the world is independently of its epistemic accessibility to us. So, for instance, the Newtonian theory of gravition is objective insofar as it tells the truth about the motion of particles submitted to gravitational forces. What it tells us, the realist contends, holds or is the case whether or not the physical world is accessible to us. The conception is semantic insofar as the notion of truth is involved, modal insofar as the conception of the possibility of a mind-independent natural world is involved and metaphysical insofar as a conception of a certain way the world is is involved. Philosophers as diverse as Berkeley, Kant and Dummett's antirealist will then ask: if this were the case, how could we know anything about it? How could we even form a bona fide conception of its possibility?
