Abstract
What sort of existence does the Sum have? Whether we affirm it to be the conceptual being of thought or the concrete existence of an individual, we will be forced to draw conclusions inimical to the Cartesian philosophy, for the alternative interpretations give rise to a serious dilemma. Jules Lequier states the dilemma in this way: "I think, therefore I am. Now in saying: 'I am,' after having said: 'I think,' either I say less, or I say more. If I say less, I am proceeding with certainty, but backwards; if I say more, I advance indeed, but by what right? What perplexity!...Such are the two aspects of this proposition which is alternately evident and sterile, pregnant and obscure for the mind that examines it. But to the extent it is evident, it is sterile; to the extent that it is fruitful, it is obscure."
