First published in 1971, Professor Putnam's essay concerns itself with the ontological problem in the philosophy of logic and mathematics - that is, the issue of whether the abstract entities spoken of in logic and mathematics really exist. He also deals with the question of whether or not reference to these abstract entities is really indispensible in logic and whether it is necessary in physical science in general.

First published in 1974. Despite the tendency of contemporary analytic philosophy to put logic and mathematics at a central position, the author argues it failed to appreciate or account for their rich content. Through discussions of such mathematical concepts as number, the continuum, set, proof and mechanical procedure, the author provides an introduction to the philosophy of mathematics and an internal criticism of the then current academic philosophy. The material presented is also an illustration of a new, more general method of approach called substantial factualism which the author asserts allows for the development of a more comprehensive philosophical position by not trivialising or distorting substantial facts of human knowledge.

First published in 1952, professor Strawson’s highly influential Introduction to Logical Theory provides a detailed examination of the relationship between the behaviour of words in common language and the behaviour of symbols in a logical system. He seeks to explain both the exact nature of the discipline known as Formal Logic, and also to reveal something of the intricate logical structure of ordinary unformalised discourse.

This book, first published in English in 1933, provides a detailed analysis of the life and concepts of the Greek philosopher Plato. The Essence of Plato’s Philosophy explores epistemology and ontology, the philosophy of nature, ethics and the philosophy of the state, and aesthetics and religion. This book will be of interest to students of philosophy.

First published in 1931, this book provides a brief overview of the essentials of philosophy. It aims to combat the notion of the inaccessibility of philosophy by providing an introduction to its history and what the author believes to a ‘minimum dose...of incontrovertible philosophical truth’. The book merely assumes an ordinary level of adult education and offers an outline of the key areas of philosophy — consciousness, reality, experience, Life, God, love, aesthetics, conduct, logic — and as such will be of interest as a very useful starting point for anyone wishing to undertake further studies.
