Fear is religion, courage is science.

Intelligence, guided by kindness, is the highest wisdom. . . .

The few took advantage of the ignorant many. They pretended to have received messages from the Unknown. They stood between the helpless multitude and the gods. They were the carriers of flags of truce. At the court of heaven they presented the cause of man, and upon the labor of the deceived they lived.

When the will defies fear, when duty throws the gauntlet down to fate, when honor scorns to compromise with death - that is heroism.

The Christians say, that among the ancient Jews, if you committed a crime you had to kill a sheep. Now they say 'charge it.' 'Put it on the slate.' The Savior will pay it. In this way, rascality is sold on credit, and the credit system in morals, as in business, breeds extravagance.
