Two chief problems of the theory of knowledge are the question of meaning and the question of verification. The first question asks under what conditions a sentence has meaning, in the sense of cognitive, factual meaning. The second one asks how we get to know something, how we can find out whether a given sentence is true or false. The second question presupposes the first one. Obviously we must understand a sentence, i.e. we must know its meaning, before we can (...) try to find out whether it is true or not. But, from the point of view of empiricism, there is a still closer connection between the two problems. In a certain sense, there is only one answer to the two questions. If we knew what it would be for a given sentence to be found true then we would know what its meaning is. And if for two sentences the conditions under which we would have to take them as true are the same, then they have the same meaning. Thus the meaning of a sentence is in a certain sense identical with the way we determine its truth or falsehood; and a sentence has meaning only if such a determination is possible. (shrink)

Shows that when Qyuine's criterion of ontological commitment is modified to allow for the legitimacy of substitutional quantification, two consequences follow: (i) fundamental questions of ontology cease to be settled by mere appeal to logical form and truth, and (ii) a powerful method for reducing ontological commitments becomes available.

I critically evaluate the influential new wave account of theory reduction in science developed by Paul Churchland and Clifford Hooker. First, I cast doubt on claims that the new wave account enjoys a number of theoretical virtues over its competitors, such as the ability to represent how false theories are reduced by true theories. Second, I argue that the genuinely novel claim that a corrected theory must be specified entirely by terms from the basic reducing theory is in fact too (...) restrictive for scientific practice and should be rejected. Basic theories co-evolve with nonbasic theories in a mutually interactive way, and thus the basic theories incorporate the concepts and concerns of nonbasic theories. Third, I show that once its ontological consequences are duly noted, the reductive part the new wave account collapses into the classical theory developed within the logical empiricist tradition. As such, it still falls prey to standard anti-reductionist argument based upon multiple realizability and the cross-classification of special science and physical science terms. (shrink)

. When I have a conscious experience of the sky, there is a bluish way it is like for me to have that experience. We may distinguish two aspects of this "bluish way it is like for me": the bluish aspect and the for-me aspect. Let us call the bluish aspect of the experience its qualitative character and the for-me aspect its subjective character . What is this elusive for-me-ness, or subjective character , of conscious experience? In this paper, I (...) examine six different attempts to account for subjective character in terms of the functional and representational properties of conscious experiences. After arguing against the first five, I defend the sixth. (shrink)

In this new book, acclaimed scholar Avrum Stroll introduces the legendary philosopher Ludwig Wittgenstein, first through his unconventional lifestyle, and secondly through Wittgenstein's own greatest works.

Contemporary hybrid logic is based on the idea of using formulas as terms, an idea invented and explored by Arthur Prior in the mid-1960s. But Prior’s own work on hybrid logic remains largely undiscussed. This is unfortunate, since hybridisation played a role that was both central to and problematic for his philosophical views on tense. In this paper I introduce hybrid logic from a contemporary perspective, and then examine the role it played in Prior’s work.

This book offers a new approach to the representation of meaning of temporally-located utterances and discourses. Temporality, the author suggests, should be taken to mean degrees of certainty, understood in turn as degrees of acceptability concerning the eventuality referred to in the speaker's utterance.

Jonathan Dancy argues in his book Moral Reasons that neither general nor specific moral principles are of any important use in moral decision making. I examine his reasons for denying any important role to such principles. With regard to general moral principles, I suggest that there are such principles that appear useful ‐ an idea that Dancy in some passages actually seems to endorse. When it comes to highly specific principles, Dancy's advice is less open to interpretation; since such principles (...) match only one situation, Dancy considers them as of no use. I contest this view by considering an example that suggests that a highly specific principle has been of use. (shrink)

It is nowadays taken for granted that the core radical sceptical arguments all pivot upon the principle that the epistemic operator in question is 'closed' under known entailments. Accordingly, the standard anti-sceptical project now involves either denying closure or retaining closure by amending how one understands other elements of the sceptical argument. However, there are epistemic principles available to the sceptic which are logically weaker than closure but achieve the same result. Accordingly the contemporary debate fails to engage with the (...) sceptical problem in its strongest form. (shrink)

The appeal of materialism lies precisely in this, in its claim to be natural metaphysics within the bounds of science. That a doctrine which promises to gratify our ambition (to know the noumenal) and our caution (not to be unscientific) should have great appeal is hardly something to be wondered at. (Putnam (1983), p.210) Materialism says that all facts, in particular all mental facts, obtain in virtue of the spatio- temporal distribution, and properties, of matter. It was, as Putnam says, (...) “metaphysics within the bounds of science”, but only so long as science was thought to say that the world is made out of matter.1 In this century physicists have learned that there is more in the world than matter and, in any case, matter isn’t quite what it seemed to be. For this reason many philosophers who think that metaphysics should be informed by science advocate physicalism in place of materialism. Physicalism claims that all facts obtain in virtue of the distribution of the fundamental entities and properties –whatever they turn out to be- of completed fundamental physics. Later I will discuss a more precise formulation. But not all contemporary philosophers embrace physicalism. Some- and though a minority not a small or un-influential one- think that physicalism is rather the metaphysics for an unjustified scientism; i.e. it is scientistic metaphysics. Those among them that think that physicalism can be clearly formulated think that it characterizes a. (shrink)

I. The Mind-Body Problem after Kripke This essay will explore an approach to the mind-body problem that is distinct both from dualism and from the sort of conceptual reduction of the mental to the physical that proceeds via causal behaviorist or functionalist analysis of mental concepts. The essential element of the approach is that it takes the subjective phenomenological features of conscious experience to be perfectly real and not reducible to anything else--but nevertheless holds that their systematic relations to neurophysiology (...) are not contingent but necessary.

This paper challenges David Chalmers' proposed division of the problems of consciousness into the `easy' ones and the `hard' one, the former allegedly being susceptible to explanation in terms of computational or neural mechanisms and the latter supposedly turning on the fact that experiential `qualia' resist any sort of functional definition. Such a division, it is argued, rests upon a misrepresention of the nature of human cognition and experience and their intimate interrelationship, thereby neglecting a vitally important insight of Kant. (...) From a Kantian perspective, our capacity for conceptual thought is so inextricably bound up with our capacity for phenomenal consciousness that it is an illusion to imagine that there are any `easy' problems of consciousness, resolvable within the computational or neural paradigms.

This is a perfect overview article that serves as a general introduction to the topic of dispositions. It is composed of six sections that review the main philosophical approaches to the most important questions: Analysis of disposition ascription, the dispositional/categorical distinction, dispositions and categorical bases, the intrinsicness of dispositions and the causal efficacy of dispositions.

This is a review of Marc Lange's _Natural Laws in Scientific Practice<D>.
