A common complaint of biologists is that their subject receives poor treatment from philosophers—it gets but a fraction of the attention accorded to physics and chemistry, and what little it does receive, is usually of the type where ‘All swans are white’ is taken to be a paradigmatic example of the state of biological thinking. It cannot be denied that this complaint is, to a great extent, justified; however, there are some notable breaches in the wall of ignorance and silence, (...) amongst which must be numbered The Ascent of Life by T.A. Goudge. In this book, starting from what is obviously a very wide knowledge of biology, Goudge attempts a careful and thorough analysis of one of the major achievements of biological thought, evolutionary theory. The conclusions that Goudge draws are many; nevertheless, one can discern running through them a common theme, namely that whilst evolutionary theory is indeed a legitimate branch of science, to assume that it is a science of the same nature as physics and chemistry would be a grave error. Goudge argues that, despite certain similarities to other branches of science, the essential aims, methods and results of evolutionary theory are peculiar unto itself. (shrink)

The question ‘Are there inherent differences among the phenomena studied by different sciences which require inherently different methodologies?’ has received considerable attention during the last century. Much of the debate has been fueled by logical positivism and logical empiricism, both of which embrace a commitment to the reduction of theories and the ultimate unity of science. This commitment presupposes that there are no inherent fundamental differences since any inherent differences would undermine the connected goals of reduction and unification. Hence, logical (...) positivists and logical empiricists have attempted to show that the supposed differences are illusory. For example, Hempel and Nagel both argued vigorously that there are no inherent differences. Their strategy was to analyze a purported difference and argue either that the feature responsible for the difference was not really present in the non-physical science or that it was after all present in the physical sciences as well.
