Central Works of Philosophy, Volume 4 [PDF ebook] 
The Twentieth Century: Moore to Popper

Ranging over 2, 500 years of philosophical writing, this five-volume collection of essays is an unrivalled companion to the study and reading of philosophy. Central Works of Philosophy provides both an overview of particular works and clear and authoritative expositions of their central ideas, giving readers the resources and confidence to read the works themselves. These books offer remarkable insights into the ideas out of which our present ways of thinking emerged and without which they cannot fully be understood.
