We Do Not Know. We Can Only

Serious Rational Criticism Is So Rare That It Should Be Encouraged. Being Too Ready To Defend Oneself Is More Dangerous Than Being Too Ready To Admit A Mistake.

True Ignorance Is Not The Absence Of Knowledge, But The Refusal To Acquire It.

I Think That There Is Only One Way To Science - Or To Philosophy, For That Matter: To Meet A Problem, To See Its Beauty And Fall In Love With It; To Get Married To It And To Live With It Happily, Till Death Do Ye Part - Unless You Should Meet Another And Even More Fascinating Problem Or Unless, Indeed, You Should Obtain A Solution. But Even If You Do Obtain A Solution, You May Then Discover, To Your Delight, The Existence Of A Whole Family Of Enchanting, Though Perhaps Difficult, Problem Children, For Whose Welfare You May Work, With A Purpose, To The End Of Your Days.

Man, Some Modern Philosophers Tell Us, Is Alienated From His World: He Is A Stranger And Afraid In A World He Never Made. Perhaps He Is; Yet So Are Animals, And Even Plants. They Too Were Born, Long Ago, Into A Physico-chemical World, A World They Never Made.

In My View, Aiming At Simplicity And Lucidity Is A Moral Duty Of All Intellectuals: Lack Of Clarity Is A Sin, And Pretentiousness Is A Crime.
