Bachelard (1884-1962) generated a corpus numbering in the dozens of books, with topics ranging from the philosophy of science to poetry, some translated from the French into English. Moreover, his works have provoked at least that number of seldom-translated major studies by others. Bachelard reads as a modern, even post-modern, scholar. His polemical position as an anti-positivist and his fascination with dynamical process place him in the emerging paradigm within semiotics' major tradition. This paper explores Bachelard's resonance with semiotic issues in the philosophy of science and his relevance to contemporary dialectics.
