Bertrand Russell Quotes About Uncertainty

• But as the work proceeded I was continually reminded of the fable about the elephant and the tortoise. Having constructed an elephant upon which the mathematical world could rest, I found the elephant tottering, and proceeded to construct a tortoise to keep the elephant from falling. But the tortoise was not more secure than the elephant, and after some twenty years of very arduous toil, I came to the conclusion that there was nothing more that I could do in the way of making mathematical knowledge indubitable.

• La exigencia de certeza es natural en el hombre, pero no deja de ser un vicio intelectual. Mientras los hombres no estén entrenados para abstenerse de juzgar en ausencia de pruebas, se dejarán llevar por profetas engreídos, y es probable que sus líderes sean fanáticos ignorantes o charlatanes deshonestos. Soportar la incertidumbre es difícil, pero también lo son la mayoría de las demás virtudes.

• Science tells us what we can know but what we can know is little and if we forget how much we cannot know we become insensitive of many things of very great importance. Theology, on the other hand induces a dogmatic belief that we have knowledge where in fact we have ignorance and by doing so generates a kind of impertinent insolence towards the universe. Uncertainty in the presence of vivid hopes and fears is painful, but must be endured if we wish to live without the support of comforting fairy tales.
