If We Wish Our Civilization

Philosophy Is A Necessary Activity Because We, All Of Us, Take A Great Number Of Things For Granted, And Many Of These Assumptions Are Of A Philosophical Character; We Act On Them In Private Life, In Politics, In Our Work, And In Every Other Sphere Of Our Lives -- But While Some Of These Assumptions Are No Doubt True, It Is Likely, That More Are False And Some Are Harmful. So The Critical Examination Of Our Presuppositions -- Which Is A Philosophical Activity -- Is Morally As Well As Intellectually Important.

All We Can Do Is Search For The Falsity Content In Our Best Theory.

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.

If You Can't Say It Simply And Clearly, Keep Quiet, And Keep Working On It Till You Can.

Whenever We Propose A Solution To A Problem, We Ought To Try As Hard As We Can To Overthrow Our Solution, Rather Than Defend It.
