In a discussion of Parfit's Drops of Water case, Zach Barnett has recently proposed a novel argument against “No Small Improvement”; that is, the claim that a single drop of water cannot affect the magnitude of a thirsty person's suffering. We first show that Barnett's argument can be significantly strengthened, and also that the fundamental idea behind it yields a straightforward argument for the transitivity of equal suffering. We then suggest that defenders of No Small Improvement could reject a Pareto principle that is presupposed in Barnett's argument and our developments of it. However, this does not save No Small Improvement, since there is a convincing argument against this claim that does not presuppose the Pareto principle.

Several distinguished philosophers have argued that since the state of affairs where nothing exists is the simplest and least arbitrary of all cosmological possibilities, we have reason to be surprised that there is in fact a non-empty universe. We review this traditional argument, and defend it against two recent criticisms put forward by Peter van Inwagen and Derek Parfit. Finally, we argue that the traditional argument nevertheless needs reformulation, and that the cogency of the reformulated argument depends partly on whether there are certain conceptual limitations to what a person can hypothetically doubt.

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.

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.

The counterfactual comparative account of harm faces problems in cases that involve overdetermination and preemption. An influential strategy for dealing with these problems, drawing on a suggestion made by Derek Parfit, is to appeal to _plural harm_—several events _together_ harming someone. We argue that the most well-known version of this strategy, due to Neil Feit, as well as Magnus Jedenheim Edling’s more recent version, is fatally flawed. We also present some general reasons for doubting that the overdetermination and preemption problems for the counterfactual comparative account can be satisfactorily solved by appealing to plural harm.

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.

Several philosophers have argued that our cosmos is either purposely created by some rational being, 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.

In value theory, the notion of an organic unity is usually associated with G. E. Moore. In his Principia Ethica, Moore provided two definitions of an organic unity. In the first section of this chapter, it is argued that both definitions fail to capture Moore’s intentions, as well as being inadequate for measurement-theoretical reasons. Section 15.2 briefly investigates whether the existence of organic unities, as conceived by Moore, entails that intrinsic or final value cannot be additively measured. In section 15.3, a number of definitions of an organic unity proposed by later authors are surveyed, and some criteria for organicity are discerned. In section 15.4, it is argued that one suggested criterion presupposes that some instances of final value are not instances of intrinsic value, in Moore’s sense. The fifth and final section contains a brief discussion of whether the existence of organic unities can plausibly be denied.

Many philosophers have claimed that extensive or additive measurement is incompatible with the existence of "higher values", any amount of which is better than any amount of some other value. In this paper, it is shown that higher values can be incorporated in a non-standard model of extensive measurement, with values represented by sets of ordered pairs of real numbers, rather than by single reals. The suggested model is mathematically fairly simple, and it applies to structures including negative as well as positive values.
