Parmenides didn't mention reference as such, but if he had he would have undoubtedly agreed with the philosophers who nowadays hold what is called "the axiom of existence": that one can only refer to what exists. The sources of possible support for this view are examined and rejected. Primary support for the axiom is given by two sorts of argument; one concerning quantification, the other summarizing a standard Parmenidean puzzle. Weaknesses in both are exposed. Finally, the relations between the axiom (...) and connected claims about predication and truth are probed, and an attempt is made to determine the limits of the mutual support these claims give one another.

Although a number of truth theorists have claimed that a deflationary theory of ‘is true’ needs nothing more than the uniform implication of instances of the theorem ‘the proposition that p is true if and only if p ’, reflection shows that this is inadequate. If deflationists can’t support the instances when replacing the biconditional with ‘because’, then their view is in peril. Deflationists sometimes acknowledge this by addressing, occasionally attempting to deflate, ‘because’ and ‘in virtue of’ formulas and their (...) close relatives. I examine what I take to be the most promising deflationist moves in this direction and argue that they fail. (shrink)
In specifying the sensory evidence for perceptual belief, thinkers have either chosen a common perceptual idiom or have invented one of their own as a starting-point for their enquiries. It is becoming clearer that the choice harbours crucial, often disputable, assumptions. I compare two sorts of constructions, a variety of propositional ones and an objectual one, and I argue that the objectual idiom is indispensable in order to explain how a perceptual belief can arise out of what is not already (...) a belief. This has implications not only for the question of how belief is generated from perceptual evidence, but also for various other controversies. I discuss two of these implications: the character of inferences from evidence, and basic belief. (shrink)
Interjections, such as those in the title, together with a few similar devices, when qualifying clauses expressing truth-conditions, or that such conditions have been satisfied, are entitled 'force-amplifiers'. Disputes between deflationary and inflationary truth-theories sometimes are assumed to turn on the supposed pivotal role that these devices are construed as playing in the interpretation of the clauses they qualify. I argue that they are not dispensable add-ons. Moreover, even in their absence the relevant clauses giving truth-conditions permit interpretations that are (...) not deflationary-friendly. I maintain that this is a significant fact about the use to which writers put them. I then defend, a thesis about force-amplifiers that makes them indispensable to the interpretation of the relevant clauses, and that renders certain moves unavailable to popular deflationist treatments.

I defend the view that justified belief is preferable to plain belief only because the former enhances the likelihood that the belief is true: call that sort of justification truth-linked. A collection of philosophical theories either state outright that this is not so, imply it via other doctrines, or adopt a notion of truth that renders the link innocuous. The discussion proceeds as follows. Issues and various positions are outlined, and needed qualifications are entered (parts I-III). We then note general (...) shortcomings of all views rejecting the truth-link, and critically examine a powerful thought experiment underlying the rejection (part IV). In the final sections we explore two other challenges to the truth-link. First (part V), we consider forms of idealized justification theory that would imply the independence of justification from the relevant sort of truth conduciveness; next (part VI) we investigate a view, Pragmatism, which maintains that epistemic justification is sanctioned by ends other than a tendency towards truth.

The evidence of blindsight is occasionally used to argue that we can see things, and thus have perceptual belief, without the distinctive visual awareness accompanying normal sight; thereby displacing phenomenality as a component of the concept of vision. I maintain that arguments to this end typically rely on misconceptions about blindsight and almost always ignore associated visual (or visuomotor) pathologies relevant to the lessons of such cases. More specifically, I conclude, first, that the phenomena very likely do not result from (...) dissociations within a single system, but from the interaction of evolutionarily distinct, if interacting, systems; second, that a closer study of spared motor abilities indicates that verbal responses of patients result not from degraded vision but from proprioception; and, finally, above chance verbal responses, being forced guesses, are not tentative beliefs and cannot become beliefs just by training patients to have more confidence in their responses.

In this book Gerald Vision argues for a new causal theory, one that engages provocatively with direct realism and makes no use of a now discredited subjectivism.

It seems almost a truism to say that colour is a sensation; and yet Young, by honestly recognizing this elementary truth, established the first consistent theory of colour. So far as I know, Thomas Young was the first who, starting from the well-known fact that there are three primary colours, sought for the explanation of this fact, not in the nature of light, but in the constitution of man. (James Clerk Maxwell, p. 267.)It is doubtless scientific to disregard certain aspects (...) when we work; but to urge that therefore such aspects are not fact, and that what we use without them is an independent real thing-this is barbarous metaphysics. (F. H. Bradley, p. 15.). (shrink)
Problems concerning identity in possible worlds and the view that proper names are rigid designators pose no threat to the doctrine that names of fictional characters (fictional names) are referential. Some philosophers, notably Saul Kripke and David Kaplan, have held otherwise; but a close examination of their arguments discovers fatal flaws in them. Furthermore, the most readily available proposals for the alternative functions of fictional names — that is, proposals in which fictional names are not referential — are open to (...) objections of a principled kind. This raises serious doubts that any such alternative could work. (shrink)
