This 5-volume collection provides all the major philosophical writings of philosopher Samuel Alexander (1859-1938). Alexander was one of the most distinguished and interesting philosophers of the turn of the century, and among the few modern thinkers to develop a comprehensive metaphysical system.

Showing the influence of the idealism dominant in Oxford at the time, it is considered a landmark work in British moral theory. Alexander's move away from idealism towards Darwinian evolutionism found full expression in his major publication, Space, Time and Deity. In this detailed and comprehensive work of speculative metaphysics Alexander expounds the 'emergent evolution' theory for which he is best known, whereby existence is hierarchically arranged and emerges in an ongoing evolutionary process.

It includes studies of Valuation, especially of Beauty and of Goodness. The set concludes with Philosophical and Literary Pieces, an excellent compilation of addresses and journal articles published after Alexander's death. Some of Alexander's most interesting philosophical work can be found here, such as 'The Mind of a Dog', 'Dr
