"The world Being and history have their own time. We can, of course, enter that time in a creative way, but none of us has it entirely in his hands.

They resist his sense of time, just as they resist a broad interpretation of their sense of time. And just as they have their own secrets and their own mystery, which is constantly catching modern enlightenment rationality off guard, they also have their own, meandering course." Hat tip to Chris Corrigan for pointing me to this.
