Voltaire, French philosopher:
Uncertainty is an uncomfortable position. But certainty is an absurd one.
Chinese proverb (according to A. Ben-Tal and L. El-Ghaoui. Robust Optimization. Princeton University Press, 2009; I haven't found the Chinese translation.):
To be uncertain is to be uncomfortable, but to be certain is to be ridiculous.
