Some food for thought:
“A state of doubt is unpleasant, but a state of certainty is ridiculous.”
– Voltaire
“I don’t have to know an answer. I don’t feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose, which is the way it really is, as far as I can tell, possibly. It doesn’t frighten me.”
– Richard Feynman
“To doubt everything or to believe everything are two equally convenient solutions; both dispense with the necessity of reflection.”
– Jules Henri PoincarĂ©
… and, last but not least:
“Let us prepare to grapple with the ineffable itself, and see if we may not eff it after all.”
– Douglas Adams
