But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . .

But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.
