Because of its concrete content, sense-certainty immediately appears as the richest kind of knowledge, indeed a knowledge of infinite wealth for which no bounds can be found, either when we reach out into space and time in which it is dispersed, or when we take a bit of this wealth, and by division enter into it. Moreover, sense-certainty appears to be the truest knowledge ... but, in the event, this very certainty proves itself to be the most abstract and poorest truth. All that it says about what it knows is just that it is; and its truth contains nothing but the sheer being of the thing.
