Plato's main concern in the "Cratylus," I claim, is to argue against the idea that we can learn about things by examining their names, and in favour of the claim that philosophers should, so far as possible, look to the things themselves. Other philosophical questions, such as that of whether we should accept a naturalist or a conventionalist theory of namng, arise in the dialogue, but are subordinate. This reading of the "Cratylus," I say, explains certain puzzling facts about the dialogue's structure and dramatic emphasis, as well as making the dialogue look better on philosophical grounds. In support of my claim, I argue that Hermogenes' conventionalist theory of naming is quite sensible, and is not refuted by Socrates; that the main purpose of the etymological section is to undermine our confidence in etymology as a form of philosophical enquiry; and that the apparently tangential and inconclusive discussions in the final section of the dialogue are best understood as illustrations of Plato's thesis about philosophical methodology

Welfarism is the view that morality is centrally concerned with the welfare or well-being of individuals. The division between welfarist and non-welfarist approaches underlies many important disagreements in ethics, but welfarism is neither consistently defined nor well understood. I survey the philosophical work on welfarism, and I offer a suggestion about how the view can be characterized and how it can be embedded in various kinds of moral theory. I also identify welfarism's major rivals, and its major attractions and weaknesses.
