The bachelardian epistemology of chemistry

Our book is both a history and a philosophy of chemistry. Gaston Bachelard is known as one of the great epistemologists of the 20th century like his contemporary Karl Popper in the Anglo-Saxon culture. Indeed it was a question first of all of going back in history in order to see the implications of chemistry as well as its multiple meanings reserved for the ancient and modern sciences. It is a question for us of managing to read beyond the multitude of the conceptions of the truth in work in the history of chemistry and this through the notion of the not a unitary dynamics and this through the epistemology bachelardienne. Thus in the first part we refer to history to understand scientific modernity and the plasticity of knowledge on the one hand and on the other hand the place occupied by the Bachelardian sense of no in scientific discourse. Then in the second part we will deal with the pluralism of truth and the coherence of truth in modern chemistry and finally in the third part we have examined on the one hand what Bachelard calls not in the light of the history of modern chemistry.
