What is the supposition that the 'certeza sensible' has about knowledge and how does Hegel criticize it?

The 'certeza sensible' supposes that the best way to know the world is through direct or intuitive experience without applying concepts to what is experienced.
Hegel argues that the 'certeza sensible' supposition is inadequate or unilateral because it conceives the individuality of objects of knowledge as something independent or even opposed to the universality.
Hegel argues that the content of the 'certeza sensible' knowledge is not unique and purely individual, but rather a universal that is determined by negation.
