Man Is A Tool-using Animal.

The Eye Of The Intellect "sees In All Objects What It Brought With It The Means Of Seeing."

He That Has Done Nothing Has Known Nothing.

Superstition! That Horrid Incubus Which Dwelt In Darkness, Shunning The Light, With All Its Racks, And Poison Chalices, And Foul Sleeping Draughts, Is Passing Away Without Return. Religion Cannot Pass Away. The Burning Of A Little Straw May Hide The Stars Of The Sky; But The Stars Are There And Will Reappear.

A Man Must Indeed Be A Hero To Appear Such In The Eyes Of His Valet.

Debt Is A Bottomless Sea.
