Avarice, The Spur Of Industry.

Truth Is Disputable; Not Taste: What Exists In The Nature Of Things Is The Standard Of Our Judgement; What Each Man Feels Within Himself Is The Standard Of Sentiment. Propositions In Geometry May Be Proved, Systems In Physics May Be Controverted; But The Harmony Of Verse, The Tenderness Of Passion, The Brilliancy Of Wit, Must Give Immediate Pleasure. No Man Reasons Concerning Another's Beauty; But Frequently Concerning The Justice Or Injustice Of His Actions.

Custom, Then, Is The Great Guide Of Human Life. It Is That Principle Alone, Which Renders Our Experience Useful To Us, And Makes Us Expect, For The Future, A Similar Train Of Events With Those Which Have Appeared In The Past.

..all Arguments Concerning Existence Are Founded On The Relation Of Cause And Effect; That Our Knowledge Of That Relation Is Derived Entirely From Experience; And All Our Experimental Conclusions Proceed Upon The Supposition That The Future Will Be Conformable To The Past. .... Without The Influence Of Custom, We Should Be Entirely Ignorant Of Every Matter Of Fact Beyond What Is Immediately Present To The Memory And Senses.

One Would Appear Ridiculous Who Would Say, That It Is Only Probable The Sun Will Rise To-morrow, Or That All Men Must Die; Thoughit Is Plain We Have No Further Assurance Of These Facts Than What Experience Affords Us.
