Context

“In that case in the ground, which promised at first to supersede contradiction, a new contradiction seems to arise. It is however a contradiction which, so far from persisting quietly in itself, is rather the expulsion of it from itself. The ground is a ground only to the extent that it affords ground: but the result which thus issued from the ground is only itself. In this lies its formalism. The ground and what is grounded are one and the same content: the difference between the two is the mere difference of form which separates simple self-relation, on the one hand, from mediation or derivativeness on the other.” source
