Concepts and methods originating in one discipline can distort the structure of another when they are applied to the latter. I exemplify this mostly with reference to systematic biology, especially problems which have arisen in relation to the nature of species. Thus the received views of classes, individuals (which term I suggest be replaced by units to avoid misunderstandings), and sets are all inapplicable, but each can be suitably modified. The concept of fuzzy set was developed to deal with species (...) and I defend its applicability. Taxa at all levels are real and participate in biological processes. Analysis of cause and pattern provides the deep structure in which metabiology is grounded; violation of this principle has led to diverse errors in biology. (shrink)

Of articles which are submitted for publication in Philosophy, a surprisingly large proportion are about the views of Richard Rorty. Some, indeed, we have published. They, along with pretty well all the articles we receive on Professor Rorty, are highly critical. On the perverse assumption that there must be something to be said for anyone who attracts widespread hostility, it is only right to see what can be said in favour of Rorty's latest collection of papers, entitled, Truth and Progress.
