The influence of Plato, his Dialogues and his ‘Academy', cast a long shadow. Around 35 Dialogues, almost all featuring Socrates as the principal figure, are generally ascribed to Plato and form one of the most important threads in Western philosophy. These four Dialogues may fall into the ‘Attributed Texts' category, but they are of sufficient interest to warrant study in our time and when set against the principal canon.

Two contrasting reflections by Aristotle which cover very particular ground. In 'On the Soul', Aristotle presents his view of the 'life essence' which, he argues, is possessed by living things whether plants, animals or humans. Not a 'soul' in the generally accepted Western use of the term, this 'soul', he says, is a life force that is indivisible from the organism that possesses it.

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 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.

Xenophon was a friend of Socrates, and yet his concise memories of the iconic philosopher have lived under the shadow of the more voluminous accounts by Plato. Yet Xenophon’s two works are, in many ways, more entertaining and more accessible, and they present a different view of the man who embodies a clear mind, temperate, ethical living, sharp intellect and humour.
