Ingratitude Is The Essence Of Vileness.

Everything In Nature Acts In Conformity With Law.

All Trades, Arts, And Handiworks Have Gained By Division Of Labor... Where The Different Kinds Of Work Are Not Distinguished And Divided, Where Everyone Is A Jack-of-all-trades, There Manufactures Remain Still In The Greatest Barbarism.

An Organized Product Of Nature Is That In Which All The Parts Are Mutually Ends And Means.

Reason In A Creature Is A Faculty Of Widening The Rules And Purposes Of The Use Of All Its Powers Far Beyond Natural Instinct; It Acknowledges No Limits To Its Projects. Reason Itself Does Not Work Instinctively, But Requires Trial, Practice, And Instruction In Order Gradually To Progress From One Level Of Insight To Another.

Ours Is An Age Of Criticism, To Which Everything Must Be Subjected.
