This book also discusses the various attacks on science and rationality that emerged during the twentieth century, and discusses very carefully the implications on the philosophy of science of the Theory of Evolution. A very unusual feature of this book is that it contains a number of poems attached at the end of certain chapters. These poems are not the usual “science poems” that are no more than the lyrical thoughts of some poets about science. They are designed to illustrate definite events in the history of science and some of the important philosophical or theological problems associated with them.
