Imre Lakatos' philosophical and scientific papers are published here in two volumes. Volume I brings together his very influential but scattered papers on the philosophy of the physical sciences, and includes one important unpublished essay on the effect of Newton's scientific achievement. Volume II presents his work on the philosophy of mathematics (much of it unpublished), together with some critical essays on contemporary philosophers of science and some famous polemical writings on political and educational issues. Imre Lakatos had an influence (...) out of all proportion to the length of his philosophical career. This collection exhibits and confirms the originality, range and the essential unity of his work. It demonstrates too the force and spirit he brought to every issue with which he engaged, from his most abstract mathematical work to his passionate 'Letter to the director of the LSE'. Lakatos' ideas are now the focus of widespread and increasing interest, and these volumes should make possible for the first time their study as a whole and their proper assessment. (shrink)

Traditionally a scientific theory is viewed as based on universal laws of nature that serve as axioms for logical deduction. In analyzing the logical structure of evolutionary biology, Elisabeth Lloyd argues that the semantic account is more appropriate and powerful. This book will be of interest to biologists and philosophers alike.

Compares classic and contemporary theories of genetics and evolution and explores the role of teleological thought in biology.

This paper investigates what molecular biology has done for our understanding of the gene. I base a new account of the gene concept of classical genetics on the classical dogma that gene differences cause phenotypic differences. Although contemporary biologists often think of genes in terms of this concept, molecular biology provides a second way to understand genes. I clarify this second way by articulating a molecular gene concept. This concept unifies our understanding of the molecular basis of a wide variety (...) of phenomena, including the phenomena that classical genetics explains in terms of gene differences causing phenotypic differences.

John Dupré explores the ways in which we categorize animals, including humans, and comes to refreshingly radical conclusions. He opposes the idea that there is only one legitimate way of classifying things in the natural world, the 'scientific' way. The lesson we should learn from Darwin is to reject the idea that each organism has an essence that determines its necessary place in the unique hierarchy of things. Nature is not like that: it is not organized in a single system. (...) For instance, there is no universal principle by which organisms can be sorted into species. We are obliged to accept that different classificatory schemes are equally valid, and to take a pluralistic view of biology and the human sciences. These provocative and readable essays move on to discuss a set of contentious topics relating to human nature. To start with, Dupré argues that the concept of a universal human nature should be rejected. He questions the relevance of evolution to explanation of human behaviour, and casts doubt on the concept of normality in human behaviour. He shows that misunderstanding of biology and evolution has lead to widespread misconceptions about human sex and gender-in particular, about sexual behaviour and gender roles. The books concludes with a pair of essays about the differences between humans and animals, which may not be quite so clear-cut as we think. (shrink)
