Gaston Bachelard (1884–1962) was a seminal figure in contemporary French philosophy.Together with Michel Foucault, Georges Canguilhem and Jean Cavaillès, he shaped the ‘French epistemological’ school of philosophy of science.In France, Bachelard is a towering presence; in the English-speaking world, he is little known.Now, Zbigniew Kotowicz gives us the first English language, in-depth presentation of the entire spectrum of Bachelard’s work: epistemology, poetic imagination and temporality. And he explores an old philosophical tradition that Bachelard’s thought opens up – atomism – a doctrine that has been almost forgotten and is much misunderstood.
