The Great End Of All Human Industry

Tis Evident That All Reasonings Concerning Matter Of Fact Are Founded On The Relation Of Cause And Effect, And That We Can Never Infer The Existence Of One Object From Another, Unless They Be Connected Together, Either Mediately Or Immediately... Here Is A Billiard Ball Lying On The Table, And Another Ball Moving Toward It With Rapidity. They Strike; And The Ball Which Was Formerly At Rest Now Acquires A Motion. This Is As Perfect An Instance Of The Relation Of Cause And Effect As Any Which We Know, Either By Sensation Or Reflection.

The Difference Between A Man Who Is Led By Opinion Or Emotion And One Who Is Led By Reason. The Former, Whether He Will Or Not, Performs Things Of Which He Is Entirely Ignorant; The Latter Is Subordinate To No One, And Only Does Those Things Which He Knows To Be Of Primary Importance In His Life, And Which On That Account He Desires The Most; And Therefore I Call The Former A Slave, But The Latter Free.
