The quest for certainty blocks the search for meaning. Uncertainty is the very condition to impel man to unfold his powers.
I may not have been sure about what really did interest me, but I was absolutely sure about what didn’t.
Uncertainty and danger are always closely allied; thus making any kind of an unknown world a world of peril and evil possibilities.
To teach how to live without certainty, and yet without being paralyzed by hesitation, is perhaps the chief thing that philosophy, in our age, can still do for those who study it.
