Curiosity Is The Thirst Of The Soul.

Plenty Is The Original Cause Of Many Of Our Needs; And Even The Poverty, Which Is So Frequent And Distressful In Civilized Nations, Proceeds Often From That Change Of Manners Which Opulence Has Produced. Nature Makes Us Poor Only When We Want Necessaries; But Custom Gives The Name Of Poverty To The Want Of Superfluities.

Where Necessity Ends, Desire And Curiosity Begin; And No Sooner Are We Supplied With Everything Nature Can Demand Than We Sit Down To Contrive Artificial Appetites.

He Who Attempts To Do All Will Waste His Life In Doing Little.

A Man Is Not Obliged Honestly To Answer A Question Which Should Not Properly Be Put.

It Is Our First Duty To Serve Society, And After We Have Done That, We May Attend Wholly To The Salvation Of Our Own Souls.
