Francis Bacon (1561-1626), 1st Viscount St Albans, Attorney General and then Lord Chancellor of England, was an immensely learned, clever and ambitious man, with considerable political influence. However, he was also a philosopher with a wide interest in science, medicine and the classification of knowledge. Throughout his life he wrote a series of essays - following the manner set particularly by Montaigne, though extending back to Aristotle and others - the first 10 of which appeared in 1597.

Sir Francis Bacon, sometimes known as the father of empiricism, was one of the major political figures of his day, his career culminating as Lord Chancellor under King James I in 1617. Bacon wrote widely, but it is the Essays (published in its third edition in 1625, the year before his death) for which he is best known. Deftly written and often displaying a cutting wit, they cover a wide range of subjects including death, love, marriage, ambition and atheism.

The leviathan is the vast unity of the State. But how are unity, peace, and security to be attained? Hobbes’ answer is sovereignty, but the resurgence of interest today in Leviathan is due less to its answers than its methods: Hobbes sees politics as a science capable of the same axiomatic approach as geometry.

John Locke and his works - particularly An Essay Concerning Human Understanding - are regularly and rightly presented as foundations for the Age of Enlightenment. His primary epistemological message - that the mind at birth is a blank sheet waiting to be filled by the experiences of the senses - complemented his primary political message: that human beings are free and equal and have the right to envision, create and direct the governments that rule them and the societies within which they live.

Aristotle considers ‘the principles and causes of change, or movement’ behind both animate and inanimate things. It is philosophy, not science, but over centuries affected the views of those involved in the ‘natural sciences’. The text emerged from the Lyceum, the school founded by Aristotle, and is accepted to be a compilation of texts, some of which - but perhaps not all - is by Aristotle. Regardless of authorship, its importance is unquestioned.

Aristotle’s Organon comprises six key essays on logic, initially collected by Theophrastus, his successor as head of the Peripatetic school, and given its final form by Andronicus some three centuries later. The six essays are: Categories, On Interpretation, Prior Analytics, Posterior Analytics, Topics and On Sophistical Refutations. One of the principal topics of Aristotle’s focus is syllogism, in which two premises (one major, one minor) lead to a conclusion. This features in Prior Analytics and On Interpretation.

Aristotle's Metaphysics was the first major study of the subject of metaphysics - in other words, an inquiry into 'first philosophy', or 'wisdom'. It differs from Physics which is concerned with the natural world: things which are subject to the laws of nature, things that move and change, are measurable. In Metaphysics, the study falls on 'being qua being' - being insofar as it is being; the causes and principles of being, the causes and principles of substances.

Paradise Lost, along with its companion piece, Paradise Regained, remain the most successful attempts at Greco-Roman style epic poetry in the English language. Remarkably enough, they were written near the end of John Milton's amazing life, a bold testimonial to his mental powers in old age. And, since he had gone completely blind in 1652, 15 years prior to Paradise Lost, he dictated it and all his other works to his daughter.

Summa Theologica consists of three main parts. The second part is divided two, and this recording presents Prima Secundae - Part I of Part II. Taken in its entirety, Summa Theologica forms an essential contribution to the canon of Catholic doctrine and was written in the last decade of his life by Thomas Aquinas (1225-1274), an Italian-born Dominican friar. Although he died before completing it, the body of thought it contains is a continuing influence to the education and guidance of students of theology in the main Christian traditions.

Plutarch (c. AD 46-AD 120) was born to a prominent family in the small Greek town of Chaeronea, about 20 miles east of Delphi in the region known as Boeotia. His best known work is the Parallel Lives, a series of biographies of famous Greeks and Romans, arranged in pairs to illuminate their common moral virtues and vices. The surviving lives contain 23 pairs, each with one Greek life and one Roman life as well as four unpaired single lives.

In 1572, Montaigne - nobleman, humanist, and thoroughly Renaissance man - retired to the seclusion of his estate in the Dordogne and started to write. From his pen poured a stream of "essays" - attempts to capture the observations that came to him on an idiosyncratic range of subjects, from ancient customs, cannibals, and books to thumbs, war-horses, and the wearing of clothes. He made the study of himself the starting point for investigations into how to live, and wrote with a startlingly modern candor about love, grief, friendship, sex, and death.

This remarkable poem, dedicated to Queen Elizabeth I, was Spenser's finest achievement. The first epic poem in modern English, The Faerie Queene combines dramatic narratives of chivalrous adventure with exquisite and picturesque episodes of pageantry. At the same time, Spenser is expounding a deeply-felt allegory of the eternal struggle between Truth and Error....

Though it first aroused anger and controversy rather than admiration and acceptance, A Theologico-Political Treatise was a landmark in the analysis of theology (with particular reference to the Bible and its Jewish and Christian interpretations) and its relationship to philosophy and politics. Spinoza’s scholarly analysis, based on careful study, demonstrated that the Bible was composed by many writers over the centuries - and that even the Pentateuch, the first five books, were not the work of Moses, as was generally assumed at the time.

He was the father of the occult, the founder of astrology, the discoverer of alchemy. He was Hermes Trismegistus, and as the scribe of the gods of ancient Egypt, he possessed all divine knowledge... which he passed on to humanity, though only those who have been tutored in its wonders can fully understand it.In this extraordinary 1912 book, three secret initiates to his teachings - who remain anonymous to this day - share their insight with all who seek to understand the mysterious underpinnings of the universe and our relationship with it.

Aristotle’s Nicomachean Ethics and Eudemian Ethics represent, in many ways, the Western classical springboard for the systematic study and implementation of ethics, the optimum behaviour of the individual. (By contrast, Aristotle’s Politics concerns the optimum blueprint for the city-state.) It is in the hands of each individual, he argues in these books on personal ethics, to develop a character which bases a life on virtue, with positive but moderate habits.
