“What men want is not knowledge, but certainty.”
Bertrand Russell
“Have not I written to thee excellent things in counsels and knowledge, / That I might make thee know the certainty of the words of truth; that thou mightest answer the words of truth to them that send unto thee? / Rob not the poor, because he is poor: neither oppress the afflicted in the gate: / For the LORD will plead their cause, and spoil the soul of those that spoiled them.”
Bible

“For my part I know nothing with any certainty, but the sight of the stars makes me dream.”

Voltaire
