In The Sciences and Philosophy Haldane discusses in 20 lectures the relation between the sciences and philosophy. The first part of the book, “The Sciences”, gives an account to the axioms or general conceptions of different parts of knowledge or science. In the second part “Philosophy” the different and apparently contradictory conceptions of the sciences and religion are discussed, focusing on their relations to each other.

In Realms of Value Perry discusses the fields of philosophy of the natural and social sciences, aesthetics, philosophy of education, and philosophy of religion in the context of the “realms” of value. The task of his study is to bring unity and order into these areas, relying on a fundamental definition of value, defining it as any interest in any object.

In his introduction, Blackburn describes this work as a cursory investigation of the philosophical schools and figures that constitute the debate between relativism and absolutism. Truth is a matter of great importance for all people, but it is particularly significant for those in scientific, philosophical and religious communities. It is to these groups of people that Blackburn’s analysis is directed.
