Originally published in 1970. This book is a collection of lectures and papers given by Professor Findlay in the 1960s. The theme is an argument for a metaphysical Absolute, in the sense of post-Hegelian Idealism. Findlay’s word for the Absolute process is ‘Enterprise’, which must be necessary in thought and reality. This ontological argument goes further that previous cosmological arguments and addresses both traditions from ancient philosophy and the modern Anglo-American school of philosophy. The book discusses the case for a Perfect Being, a Necessary Being and, in a change to Findlay’s previous published thought, presents a case for mysticism.
