It Is Not Necessary That Whilst I

What Are The Aims Which Are At The Same Time Duties? They Are Perfecting Of Ourselves, The Happiness Of Others.

To Be Beneficent When We Can Is A Duty; And Besides This, There Are Many Minds So Sympathetically Constituted That, Without Any Other Motive Of Vanity Or Self-interest, They Find A Pleasure In Spreading Joy Around Them, And Can Take Delight In The Satisfaction Of Others So Far As It Is Their Own Work. But I Maintain That In Such A Case An Action Of This Kind, However Proper, However Amiable It May Be, Has Nevertheless No True Moral Worth, But Is On A Level With Other Inclinations. . . . For The Maxim Lacks The Moral Import, Namely, That Such Actions Be Done From Duty, Not From Inclination.

The Instruction Of Children Should Aim Gradually To Combine Knowing And Doing. Among All Sciences Mathematics Seems To Be The Only One Of A Kind To Satisfy This Aim Most Completely.

The Light Dove, Cleaving The Air In Her Free Flight, And Feeling Its Resistance, Might Imagine That Its Flight Would Be Still Easier In Empty Space.

There Is Nothing Higher Than Reason.
