This is a translation from the French -- the French is beautiful and clear. There are, I believe seven volumes to this series. I have read the the first four of them -- the three volumes on the Ancient and Medieval period, and the volume on Descartes, Spinoza, Leibniz, and Bacon. They are the single best, brief (they are quite short) history of philosophy I know of --
Coplestone was a Jesuit, and thought every major thinker was a Thomist is disguise; and Russell's History of Philosophy is absolute dreck, as he did not believe in the existence of universals -- and thought all such talk was merely 'nonsense'. It is a bit hard to write a history of western thought, if you don't understand the arguments for universals, n'est pas?
