In a series of three small books, Pierre-Marie Emonet brings the riches of philosophy within the reach of all, not just those with the time and inclination to work through erudite philosophical treatises. Reaching out to the ordinary person unfamiliar with technical philosophical language, he frequently turns to the words of the poets in order to approach the same truths investigated by the philosophers, recognising that "the poets also are attracted -- like the bee by the flower -- by what is most profound, most hidden, most substantial in the things of nature". In this first volume, Emonet introduces the basic principles of classical Thomistic metaphysics using clear, simple language, exploring the mystery of the origin of things in the world, their purpose, and their final end. The following two volumes will treat the philosophy of the human person and the philosophy of God.
