Sartre’s concepts change meaning across Being and Nothingness due to his Cartesian method

Evidence

Sartre’s methodological solipsism is explained by his employment of a Cartesian method that proceeds from the abstract and simple to the concrete and complex. For this reason, Sartre formally introduces the existence of Others only in Part III. Failure to take Sartre’s Cartesian method seriously makes accurate assessment of Being and Nothingness as a whole impossible, for the meanings of all of his basic concepts change over the course of the text. — Christine Daigle, Jacob Golomb (eds.), Beauvoir and Sartre, 212
