This paper advances the thesis that we can justifiably believe philosophically interesting possibility statements. The first part of the paper critically discusses van Inwagens skeptical arguments while at the same time laying some of the foundation for a positive view. The second part of the paper advances a view of conceivability in terms of imaginability, where imaginging can be propositional, pictorial, or a combination of the two, and argues that conceivability can, and often does, provide us with justified beliefs of what is metaphysically possible. The notion of scenarios is developed, as is an account of how filling out scenarios can uncover a defeater or, in many cases, strengthen the justification for the relevant possibility statement.

In Naming and Necessity' Saul A. Kripke gives two types of examples of contingent truths knowable a priori. So he disagrees with the first leg of the thesis. As we will see later, his examples depend on the direct designation theory of names. While there have been attempts to provide examples of the contingent a priori that do not depend on that theory, most of those examples should be viewed as expansions, or modifications, of Kripke's examples. Philip Kitcher, for example, gives an interesting example that has nothing to do with theories of names, but is produced using the indexical 'actual'.2 His example, however, is a variation of Kripke's Neptune Type example.' In what follows I will focus on Kripke's two types of examples and modifications of them. I will argue that although both types of example fail, it is possible to modify his Standard Metre example in such a way that we have an example of the contingent a priori

Horgan and Timmons, with their Moral Twin Earth arguments, argue that the new moral realism falls prey to either objectionable relativism or referential indeterminacy. The Moral Twin Earth thought experiment on which the arguments are based relies in crucial ways on the use of intuitions. First, it builds on Putnam’s well-known Twin Earth example and the conclusions drawn from that about the meaning of kind names. Further, it relies on the intuition that were Earthers and Twin Earthers to meet, they would be able to have genuine moral disagreements. I will argue that the similarities with Putnam’s thought experiment are questionable and so the reliance on Putnam-like intuitions is questionable. I will then further argue that even if we accept the intuitions that Horgan and Timmons rely on, the anti-realist conclusion is not warranted due to there being more to the meaning of kind terms than the argument assumes. Once we develop the meaning of kind terms further we can acknowledge both that Earthers and Twin Earthers refer to different properties with their moral terms, and that in spite of that they can have a substantive disagreement due to a shared meaning component.

Gareth Evans and John McDowell have challenged the traditional reading of Frege according to which Frege accepted propositions that are not object dependent, i.e., propositions that can exist even though the proper names that occur in the sentences that express them do not refer. A consequence of the Evans‐McDowell interpretation of Frege is that if someone hallucinates that there is an oasis in front of her, then there is no thought of an oasis but only an illusion of a thought. No reference entails no sense, and no sense entails no thought.This paper will focus on Frege's views on the issue and, in particular, whether there is any evidence that the mature Frege, i.e., after he introduced the sense/reference distinction, did not accept propositions that are not object dependent. It will also address one of the consequences of the Evans‐McDowell reading of Frege, arguing that they have ignored one of his important insights into natural languages

In a couple of recent papers Deborah Tollefsen has argued that groups should be viewed as having some of the intentional and epistemic properties as do individuals. In “Organizations as True Believers” she argues that corporations really do have intentional states.1 In “Collective Epistemic Agency”2 she continues her development of group agency and she now argues that collectives can be genuine knowers. The target of her arguments is, naturally, the wide spread view that “knowers are individuals, and knowledge is generated by mental processes and lodged in the mind-brain.”3 According to Tollefsen, “An epistemic agent is a deliberator that is subject to epistemic assessment; she can be charged with incoherency, inconsistency, ambiguity, and so on.”4 Further, “To be a deliberator in the rich sense in which you or I deliberate is to be subject to the immediacy that is characteristic of reason. When we engage in reasoning (and assuming we have the appropriate desires) we are moved to act immediately or think in accordance with the reasons that we arrive at through deliberation.”5 When we identify which attitudes and acts should be shaped or informed, then such identification takes place from a point of view. Typically, the point of view is the first person singular I, but Tollefsen argues that reflections on group deliberation show that the we-concept often marks the point of view in question. So, Tollefsen argues in effect that 1. A group can be a deliberator 2. A deliberator, in the sense being discussed, is an epistemic agent 3. An epistemic agent can have knowledge 4. So a group can have knowledge. The bulk of Tollefsen’s paper, “Collective Epistemic Agency,” is focused on arguing that (1) is true, i.e., that a group can be a deliberator. One of the examples she uses to make her case involves the decision made by a college admissions committee. The three committee members consider each candidate and vote ‘yes’ or ‘no’ depending on whether or not the candidate should be accepted into the program..

Plantinga grants that there are possible worlds with freedom and no moral evil, but he argues that it is possible that although God is omnipotent, it is not within God’s power to actualize a world containing freedom and no moral evil. Plantinga believes that the atheologian assumes that it is necessary that it is within an omnipotent God’s power to actualize these better worlds, but in fact, Plantinga argues, this is demonstrably not the case. Since so many philosophers have regarded Plantinga’s Free Will Defense to be a definitive solution to the logical problem of evil, the focus of the debate of the problem of evil has changed from the logical problem of evil to the evidential problem of evil. But we believe that the atheist tossed in the towel too early, and the theist celebrated victory too early. We will argue that Plantinga’s argument does not succeed. Mackie, incidentally, thought the same. He wrote “But how could there be logically contingent states of affairs, prior to the creation and existence of any created beings with free will, which an omnipotent god would have to accept and put up with? This suggestion is simply incoherent.” In this essay we argue that Plantinga fails to demonstrate that it is possible that God is omnipotent, and it is not within God’s power to actualize a world containing freedom but lacking moral evil. Thus Plantinga does not refute Mackie’s response to the Free Will Defense, and the point of Mackie’s question “Why could God not have made men such that they always freely choose the good?” still stands unrefuted.

The thesis that the necessary and the a priori are extensionally equivalent consists of two independent claims: 1) All a priori truths are necessary and 2) all necessary truths are a priori. In Naming and Necessity1 Saul A. Kripke gives examples of necessary but a posteriori truths, so he disagrees with the second leg of the thesis.2 His examples are of two types; on the one hand statements involving essential properties and on the other hand true identity statements. My concern will be with examples of the second type and whether they refute (2). (2), however, is ambiguous and can mean one of three things.

n Naming and Necessity Saul Kripke criticized descriptivist theories of proper names and suggested a ‘better picture’ as a replacement. But while the ‘better picture’ that Kripke provided was very interesting and stimulating, it was little more than a sketch of a theory that needed much work and refinement. While Kripke argued that proper names are not synonymous with definite descriptions or clusters of definite descriptions, he was silent on what the semantic contents of names might be. Further, he even speculated in the introduction to his book that the apparatus of propositions might break down given his arguments, thus further adding to the need to develop the agenda that he got underfoot. Still further, in his third lecture Kripke extended his account of proper names as being rigid designators to natural kind terms without providing arguments for such an extension and without arguing specifically that natural kind names are rigid designators. Consequently, it is not clear what one should think about his well known arguments regarding the epistemic and modal status of identity statements, such as ‘water is H2O.’
