Dorothy Rowe's book amounts to a spectacularly missed chance to make a significant contribution to the very important questions the author set out to address. The book promises to provide an answer to "why our beliefs about the nature of death and the purpose of life dominate our lives," but ends up being a bizarre hodgepodge of self-help psychology, uninformative case studies, and a large number of disconnected personal observations -- the whole thing peppered here and there with philosophical and even political considerations.

The debate about the levels of selection has been one of the most controversial both in evolutionary biology and in philosophy of science. Okasha’s book makes the sort of contribution that simply will not be able to be ignored by anyone interested in this field for many years to come. However, my interest here is in highlighting some examples of how Okasha goes about discussing his material to suggest that his book is part of an increasingly interesting trend that sees scientists and philosophers coming together to build a broadened concept of “theory” through a combination of standard mathematical treatments and conceptual analyses. Given the often contentious history of the relationship between philosophy and science, such trend cannot but be welcome.
