John Broome has argued that incomparability and vagueness cannot coexist in a given betterness order. His argument essentially hinges on an assumption he calls the ‘collapsing principle’. In an earlier article I criticized this principle, but Broome has recently expressed doubts about the cogency of my criticism. Moreover, Cristian Constantinescu has defended Broome’s view from my objection. In this paper, I present further arguments against the collapsing principle, and try to show that Constantinescu’s defence of Broome’s position fails.
Gustafsson and Espinoza have recently argued that the ‘small-improvement argument’, against completeness as a rationality requirement for preference orderings, is defective. They claim that the two main premises of the argument conflict, and hence should not both be accepted. I show that this conflict can be avoided by modifying one of the premises.
Ruth Chang has defended a concept of "parity", implying that two items may be evaluatively comparable even though neither item is better than or equally good as the other. This article takes no stand on whether there actually are cases of parity. Its aim is only to make the hitherto somewhat obscure notion of parity more precise, by defining it in terms of the standard value relations. Given certain plausible assumptions, the suggested definiens is shown to state a necessary and (...) sufficient condition for parity, as this relation is envisaged by Chang. (shrink)
John Broome has argued that alleged cases of value incomparability are really examples of vagueness in the betterness relation. The main premiss of his argument is ‘the collapsing principle’. I argue that this principle is dubious, and that Broome's argument is therefore unconvincing. Correspondence:c1 Erik.Carlson@filosofi.uu.se.
The well-known "Consequence Argument" for the incompatibility of freedom and determinism relies on a certain rule of inference; "Principle Beta". Thomas Crisp and Ted Warfield have recently argued that all hitherto suggested counterexamples to Beta can be easily circumvented by proponents of the Consequence Argument. I present a new counterexample which, I argue, is free from the flaws Crisp and Warfield detect in earlier examples.
An agent may abandon an initiated action plan, although he doesnot acquire new information or encounter unforeseen obstacles.Such dynamic inconsistency can be to the agent'';s guaranteeddisadvantage, and there is a debate on how it should rationallybe avoided. The main contenders are the sophisticated andthe resolute approaches. I argue that this debate is misconceived,since both approaches rely on false assumptions about theperformability of action plans. The debate can be reformulated,so as to avoid these mistaken assumptions. I try to show that sucha (...) reformulation must rely on certain implausible claims. (shrink)
In Section 1, I rehearse some arguments for the claim that morality should be ``action-guiding'', and try to state the conditions under which a moral theory is in fact action-guiding. I conclude that only agents who are cognitively and conatively ``ideal'' are in general able to use a moral theory as a guide to action. In Sections 2 and 3, I discuss whether moral ``actualism'' implies that morality cannot be action-guiding even for ideal agents. If actualism is true, an ideal (...) agent will know about her own future actions. Since such foreknowledge is often thought to be incompatible with deliberation, and since action-guidance presupposes the possibility of deliberation, there is an apparent difficulty in combining actualism with the requirement of action-guidance. In opposition to an argument by Jan Österberg, I try to show that actualism and action-guidance are in fact compatible. (shrink)
Whether or not intrinsic value is additively measurable is often thought to depend on the truth or falsity of G. E. Moore's principle of organic unities. I argue that the truth of this principle is, contrary to received opinion, compatible with additive measurement. However, there are other very plausible evaluative claims that are more difficult to combine with the additivity of intrinsic value. A plausible theory of the good should allow that there are certain kinds of states of affairs whose (...) intrinsic value cannot be outweighed by any number of states of certain other, less valuable, kinds. Such``non-trade-off'' cannot reasonably be explained in terms of organic unities, and it can be reconciled with the additivity thesis only if we are prepared to give up some traditional claims about the nature of intrinsic value.

Frances Howard-Snyder has argued that objective consequentialism violates the principle that ‘ought’ implies ‘can’. In most situations, she claims, we cannot produce the best consequences available, although objective consequentialism says that we ought to do so. Here I try to show that Howard-Snyder's argument is unsound. The claim that we typically cannot produce the best consequences available is doubtful. And even if there is a sense of ‘producing the best consequences’ in which we cannot do so, objective consequentialism (...) does not entail that we ought, in this sense, to produce the best consequences.

Several philosophers have argued that our cosmos is either purposely created by some rational being(s), or else just one among a vast number of actually existing cosmoi. According to John Leslie and Peter van Inwagen, the existence of a cosmos containing rational beings is analogous to drawing the winning straw among millions of straws. The best explanation in the latter case, they maintain, is that the drawing was either rigged by someone, or else many such lotteries have taken place. Arnold (...) Zuboff claims that each person is justified in concluding that her existence did not depend on a particular sperm cell first reaching the egg. If it did so depend, her existence would be extremely improbable, and an incredible coincidence for her. Similarly, intelligent life would be an incredible coincidence for us, if this were the only actual cosmos. We reject both these purported analogies. Referring to the nonheredity of 'surprise value', we conclude that an evolutionary explanation of the presence of rational beings is sufficient; there is no further need to explain the basic features of our cosmos which make intelligent life possible. This point concerning surprise value also reveals a fundamental disanalogy between straw-drawing and cosmos creation. (shrink)
This paper criticizes the consequentialist theory recently put forward by Fred Feldman. I argue that this theory violates two crucial requirements. Another theory, proposed by Peter Vallentyne, is similarly flawed. Feldman's basic ideas could, however, be developed into a more plausible theory. I suggest one possible way of doing this.
