This is the first critically evaluative study of Gaston Bachelard's
philosophy of science to be written in English. Bachelard's professional
reputation was based on his philosophy of science, though that aspect of
his thought has tended to be neglected by his English-speaking readers.
Dr Tiles concentrates here on Bachelard's critique of scientific
knowledge. Bachelard emphasised discontinuities in the history of
science; in particular he stressed the ways of thinking about and
investigating the world to be found in modern science. This, as the
author shows, is paralleled by those debates among English-speaking
philosophers about the rationality of science and the
'incommensurability' of different theories. To these problems Bachelard
might be taken as offering an original solution: rather than see
discontinuities as a threat to the objectivity of science, see them as
products of the rational advancement of scientific knowledge. Dr Tiles
sets out Bachelard's views and critically assesses them, reflecting also
on the wider question of how one might assess potentially
incommensurable positions in the philosophy of science as well as in
science itself.
