Abstract

Gaston Bachelard began his academic career as a teacher of physics and chemistry, turning eventually to the history and philosophy of science: a personal evolution not uncommon in France, which since the turn of the century has also offered the examples of Duhem, Poincaré and Meyerson. Unlike these older contemporaries, however, Bachelard took as his special province not the logical structure of scientific theory, or the norms of theory construction, but the inventive spontaneity or “dynamism” of scientific thought. While celebrating science as the ultimate expression of reason, he paid as much attention to its imaginative false starts as to the rational explanations it adopts. By 1938, moreover, he had turned explicitly to the activity of imagination: this became the general theme of a number of works that revolve freely about the four elements of an earlier and more poetic “science,” and the philosopher's field eventually was to become nothing less than his total experience, whether reasoned, lived or dreamed.
