Context

“It is constantly oscillating between extreme rationalization of reality which tends to break up that thought into standard reasons and its extreme irrationalization which tends to deify it. But this divorce is only apparent. It is a matter of reconciliation, and, in both cases, the leap suffices. It is always wrongly thought that the notion of reason is a oneway notion. To tell the truth, however rigorous it may be in its ambition, this concept is nonetheless just as unstable as others. Reason bears a quite human aspect, but it also is able to turn toward the divine.” source
