The "Posterior Analytics" contains some of Aristotle's most influential thoughts in logic, epistemology, metaphysics and the philosophy of science. The first book expounds and develops the notions of a demonstrative argument, and of a formal, axiomatized science. The second discusses a cluster of problems raised by the axioms of principles of such a science, and investigates in particular the theory of definition.;This volume, like the others in the "Clarendon Aristotle" series, is intended to serve the needs of readers of Aristotle without a knowledge of Greek. For this second edition the translation has been completely rewritten, with the aims of greater elegance and greater fidelity to the Greek. The commentary elucidates and assesses Aristotle's arguments from a philosophical point of view. It has been extensively revised to take account of the scholarship of the last 20 years.

Here are Sappho's songs and poems as English poems, all her famous pieces, all the fragments that can make connected sense, and all the discoveries of 2004 and 2014. These translations set out to be good English poetry first and foremost, and succeed well beyond other current versions. They have been made directly from Sappho's Greek, by a poet with three collections to his credit, and are relatively close to the Greek. Each piece has a concise footnote that explains references and allusions, and suggests critical appreciation. A substantial Afterword says much more about Sappho's themes, her art and style, and her historical setting. Sappho is one of the greatest poets of the western world. She lived on the Greek island of Lesbos around 600 BCE, near the very beginning of western literature, and composed 300 or so poems and songs. Her poems create a woman-centred world in which women and relationships are highly valued, a world of beauty and grace, love and loss, sandals and hairbands, all sometimes exalted and idealised. She opposes women's values to those of the dominant male society around her, and is the first to do this in the western canon. She was famous in her lifetime and has been deeply admired ever since.

No man can live a happy life, or even a supportable life, without the study of wisdom Lucius Annaeus Seneca (4 BC-AD 65) is one of the most famous Roman philosophers. Instrumental in guiding the Roman Empire under emperor Nero, Seneca influenced him from a young age with his Stoic principles. Later in life, he wrote Epistulae Morales ad Lucilium, or Letters from a Stoic, detailing these principles in full. Seneca's letters read like a diary, or a handbook of philosophical meditations. Often beginning with observations on daily life, the letters focus on many traditional themes of Stoic philosophy, such as the contempt of death, the value of friendship and virtue as the supreme good. Using Gummere's translation from the early twentieth century, this selection of Seneca's letters shows his belief in the austere, ethical ideals of Stoicism - teachings we can still learn from today.
