The Retreat from Authority
Popper did not set out to produce an all-embracing philosophy after the style of the great metaphysical system builders of the past. Rather, he proceeded in the tradition pioneered by Russell of piecemeal analysis of separate problems. But as JoIm Watkins points out ~ in his essay 'The Unity of Popper's Thought' (1974, Ch. 11), something like a systematic philosophy emerges as a result of connections and unifying ideas that link his thought in different fields.
