For Classical thought, in other words, finitude (as a determination positively constituted on the basis of the infinite) provides an account of those negative forms, which are body, needs, language, and the limited knowledge it is possible to have of them; for modern thought, the positivity of life, of production and labour (which have their own existence, historicity, and laws) provides a foundation for the limited character of knowledge as their negative correlation; and, inversely, the limits of knowledge provide a positive foundation for the possibility of knowing, though in an experience that is always limited, what life, labour, and language are.
