Anyone interested in theories of moral or human practice will find in Aristotle\'s Nicomachean Ethics one of the few basic models relevant through to today. At the centre of his analysis, both sober and cautious, are such concepts as happiness, virtue, choice, prudence, incontinence, pleasure and friendship. Aristotle\'s arguments are by no means of merely historical interest, but continue to exert a key influence on present-day ethical debate. The thirteen contributions in this volume present the foundations of Aristotle\'s investigation, along with the modern background of its reception.
