I Am Opposed To Looking Upon Logic

No Number Of Sightings Of White Swans Can Prove The Theory That All Swans Are White. The Sighting Of Just One Black One May Disprove It.

[great Scientists] Are Men Of Bold Ideas, But Highly Critical Of Their Own Ideas: They Try To Find Whether Their Ideas Are Right By Trying First To Find Whether They Are Not Perhaps Wrong. They Work With Bold Conjectures And Severe Attempts At Refuting Their Own Conjectures.

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.

We Never Know What We Are Talking About.
