Fact I Know; And Law I Know;

[scientists] Have Learned To Respect Nothing But Evidence, And To Believe That Their Highest Duty Lies In Submitting To It However It May Jar Against Their Inclinations.

Genius As An Explosive Power Beats Gunpowder Hollow; And If Knowledge, Which Should Give That Power Guidance, Is Wanting, The Chances Are Not Small That The Rocket Will Simply Run Amuck Among Friends And Foes.

The Mathematician Starts With A Few Propositions, The Proof Of Which Is So Obvious That They Are Called Self-evident, And The Rest Of His Work Consists Of Subtle Deductions From Them. The Teaching Of Languages, At Any Rate As Ordinarily Practiced, Is Of The Same General Nature Authority And Tradition Furnish The Data, And The Mental Operations Are Deductive.

We Live In A World Which Is Full Of Misery And Ignorance, And The Plain Duty Of Each And All Of Us Is To Try To Make The Little Corner He Can Influence Somewhat Less Miserable And Somewhat Less Ignorant Than It Was Before He Entered.

The Great End Of Life Is Not Knowledge But Action.
