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.
