This book deserves the best recommendations not only for the translations used (most I believe are from the Oxford works on Aristotle, including the translation of De Anima of W.D. Ross,, etc.) but for the publication format itself. It isn't as heavy as the number of pages would sugest and for a student who needs to study most of the Aristotelian Philosophy it is a lot cheaper to use this edition then to buy most of them separately.
The book is simply organized without larger introductions wich I personally prefer because they tend to transform into critiques and analyses of the woks introduced and the organization of each work with a detailed index is enough for someone who wants to read Aristotle without any preconceived ideia of his Philosophy.
Besides, it's Aristotle. If you wanna know Philosophy, you have to go there.
The Basic Works of Aristotle, edited by Richard McKeon, Random House, 1941, 1514 ff.
This edition of the work of Greek philosopher Aristotle contains Organon, the Physics, On The Heavens, On Generation And Corruption, On The Soul, the 3 Short Physical Treatises (On memory, On dreams, and On prophesy), the three zoological treatises, Metaphysics, the Nicomachean Ethics, Politics, Rhetoric, and Poetics. These are all the undisputed writings of Aristotle that have been passed down to us. The text is a little stilted in places, deriving as it does from the 1940s and, even before that, from an edition of Aristotle's works produced by the Berlin Academy in the 19th century. However, for any student of Aristotle (this work is not really intended for general readership) this is an excellent volume to have. It is useful to be able to read the 'original' text (which of course was written in ancient Greek) for reference once one has read more accessible short biographies, like that of Jonathan Barnes for Oxford U.P. (1982) or by John Vella for Continuum (2008: one of the Guides for the Perplexed). There is also an extended section on Aristotle in Bertrand Russell's History of Western Philosophy and in Volume 1 by Terence Irwin of Oxford's History of Western Philosophy.
This is a nice english translation, easy to read and is very useful as an accompaniment to the more literal translation I use for class which is naturally much harder to read. It has the major works The Metaphysics, The Ethics etc. in full and also useful excerpts of other works. If you want the complete Aristotle go with the Oxford version by Barnes, if not I recommend this
