De rerum natura (The Way Things Are) is a 1st century BC didactic poem by the Roman poet and philosopher Lucretius with the goal of explaining Epicurean philosophy to a Roman audience. Lucretius presents the principles of atomism; the nature of the mind and soul; explanations of sensation and thought; the development of the world and its phenomena; and explains a variety of celestial and terrestrial phenomena. The universe described in the poem operates according to these physical principles, guided by fortuna, "chance," and not the divine intervention of the traditional Roman deities.

The Roman philosopher's didactic poem in 6 parts, De Rerum Natura — On the Nature of Things — theorizes that natural causes are the forces behind earthly phenomena and dismisses divine intervention. Derived from the philosophical materialism of the Greeks, Lucretius' work remains the primary source for contemporary knowledge of Epicurean thought.

Book IV of Lucretius' great philosophical poem deals mainly with the psychology of sensation and thought. The heart of this book is a new text, incorporating the latest scholarship on the text of Lucretius, with a clear prose facing translation. The commentary concentrates on the thought of the text (relating it to other philosophers beside Epicurus) and the poetry of the Latin, placing the text in relation to Roman literature in general, and attempting to demonstrate the poetic genius of Lucretius. The introduction deals with the didactic tradition in ancient literature and Lucretius' place in it, the structure of De Rerum Natura, the salient features of the philosophy of Epicurus and the transmission of the text.

This book provides an overview of Lucretius' philosophical poem 'De rerum natura' intended to clarify the poem's overarching themes to a first-time reader. It also gives a brief running commentary on the individual books as well as more detailed notes on selected passages, which are reproduced in the original Latin.

`Therefore this terror and darkness of the mind Not by the sun's rays, nor the bright shafts of day, Must be dispersed, as is most necessary, But by the face of nature and her laws.' Lucretius' poem On the Nature of the Universe combines a scientific and philosophical treatise with some of the greatest poetry ever written. With intense moral fervour Lucretius demonstrates to humanity that in death there is nothing to fear since the soul is mortal, and the world and everything in it is governed not by the gods, but by the mechanical laws of nature. By believing this, men can live in peace of mind and happiness. Lucretius bases his argument on the atomic theory expounded by the Greek philosopher Epicurus. His poem explores sensation, sex, cosmology, meteorology, and geology through acute observation of the beauties of the natural world and with moving sympathy for man's place in it. Sir Ronald Melville's accessible and accurate verse translation is complemented by an introduction and notes situating Lucretius' scientific theories within the thought of 1st century BCE Rome and discussing the Epicurean philosophy that was his inspiration and why the issues Lucretius' poem raisies about the scientific and poetical views of the world continue to be important.

First published in 2000, this translation of one of the great works of Western political thought is based on the assumption that when Plato chose the dialogue form for his writing, he intended these dialogues to sound like conversations - although conversations of a philosophical sort. In addition to a vivid, dignified and accurate rendition of Plato's text, the student and general reader will find many aids to comprehension in this volume: an introduction that assesses the cultural background to the Republic, its place within political philosophy, and its general argument; succinct notes in the body of the text; an analytical summary of the work's content; a full glossary of proper names; a chronology of important events; and a guide to further reading. The result is an accomplished and accessible edition of this seminal work, suitable for philosophers and classicists as well as historians of political thought at all levels.
