'...I believe it is the duty of every intellectual to be aware of the privileged position he is in; to write as simply and clearly as he can, and as civilized as he can, and never to forget the great problems which beset mankind and which demand new and bold but patient thought, and the Socratic modesty of the man who knows how little he knows...' (from 'How I See Philosophy')

"Karl Popper is generally regarded as one of the greatest philosophers of science of the 20th century. He was also a social and political philosopher of considerable stature, a self-professed 'critical-rationalist', a dedicated opponent of all forms of scepticism, conventionalism, and relativism in science and in human affairs generally, a committed advocate and staunch defender of the 'Open Society', and an implacable critic of totalitarianism in all of its forms." (Stanford Encyclopaedia of Philosophy)

An important group of working drafts and research papers of one of the most important philosophers of the twentieth century. This group of papers mostly date from when Popper was in his early 80s but still writing and actively developing his thought. The range of topics covered in these manuscripts and typescripts are indicative of Popper's impressive range, taking in logic (especially the Popper-Miller theorem on the impossibility of inductive probability), quantum mechanics, his theory of mind, and his theory of evolution and "world 3". The quantity of drafts found here shed exceptional light on Popper's compositional process through the repeated redrafting and refining of his thoughts. These pieces appeared in various different publications. The zestful introductory essay 'How I See Philosophy' was first printed in the 1975 collection The Owl of Minerva: Philosophers on Philosophy, for example, whilst several others (including, with a slightly different title, the important 'Knowledge, Evolution and the Search for a Better World'), were eventually collected in the 1994 collection of Popper's essays, In Search of a Better World.
