It is difficult to translate the title “Wissen und Glauben” into English, because there is a debate between Kant, Jacobi, Fichte and Hegel behind it. Through Fichtes “Wissenschaftslehre” knowledge has been accepted as the basic element of all scholarship, whereas faith belongs to religion.First of all we will show, that knowledge and faith have an independent root. Each can exist by itself whithout the other one. Secondly, we will show how they complement one another. In fact faith can be sufficient (...) for the individual without knowledge. But faith can only achieve its richness and its public effectiveness together with knowledge, the πλήρωμα of faith needs knowledge. Knowledge on the other hand can neither take its depth nor reach its totality without faith. Knowledge that wants to enlighten itself must rely on faith. Faith shows knowledge that it is neither fully founded on man nor can it be fully considered as an image of the universe. On the one hand faith is criticism of self-empowered knowledge, on the other hand it is the way to surpass knowledge and to complete it. (shrink)
