An English translation of Bachelards sixth book in which he seeks to develop a metaphysical context for modern atomistic science.French philosopher Gaston Bachelard 18841962 is best known in the Englishspeaking world for his work on poetics and the literary imagination but much of his oeuvre is devoted to epistemology and the philosophy of science. Like Thomas Kuhn whose work he anticipates by three decades Bachelard examines the revolution taking place in scientific thought but with particular attention to the philosophical implications of scientific practice. Atomistic Intuitions published in 1933 considers past atomistic doctrines as a context for proposing a metaphysics for the scientific revolutions of the twentieth century. As his subtitle indicates in this book Bachelard proposes a classification of atomistic intuitions as they are transformed over the course of history. More than a mere taxonomy this exploration of atomistic doctrines since antiquity proves to be keenly pedagogical leading to an enriched philosophical appreciation of modern subatomic physics and chemistry as sciences of axioms. Though focused on philosophy of science the perspectives and intuitions Bachelard garnered through this work provide a unique and even essential key to understanding his extensive writings on the imagination. Roch C. Smiths translation and explanatory notes will help to make this aspect of Bachelards thought accessible to a wider readership particularly in such fields as aesthetics literature and history.
