This essay is concerned with the question whether there is anything left of the Tractatus criticisms of Frege and Russell, if the principles on which those criticisms are apparently based are “thrown away.” I consider two examples of Tractarian arguments that criticize Russell, both of which may appear to rest on the context principle. I discuss only briefly Wittgenstein’s argument against Russell on the theory of types, but I look in detail at his criticism of Russell on generality. I show how that criticism can be understood independently of any supposed Tractarian principles. I also consider the importance of ideas in Russell’s Principles of Mathematics for the development of Wittgenstein’s thought, including the distinction between saying and showing.

Wittgensteinian ethics, it may be thought, is committed to detailed examination of realistically described cases, and hence to eschewing the abstract hypothetical cases, many of them quite bizarre, found in much contemporary moral theorizing. I argue that bizarre cases may be helpful in thinking about ethics, and that there is nothing in Wittgenstein's approach to philosophy that would go against this. I examine the case of the ring of Gyges from the Republic; and I consider also some contemporary arguments about thought-experiments in philosophy.
