"The content of this work is of vital importance for the new generation of theologians, biblical scholars, and apologists. The historical journey from the first school of philosophy in the sixth century BC to the philosophers of the twentieth century introduces the reader to an understanding of the development of thought that has shaped the world. Its clear language makes it a mandatory textbook for an introduction to philosophy in educational institutions and essential reading for those interested in growing in the fields of philosophy and apologetics."
