Don't fear god, Don't worry about death; What is good is easy to get, and What is terrible is easy to endure

The mind that is much elevated and insolent with prosperity, and cast down with adversity, is generally abject and base.

There is no such thing as justice or injustice among those beasts that cannot make agreements not to injure or be injured. This is also true of those tribes that are unable or unwilling to make agreements not to injure or be injured.

Men, believing in myths, will always fear something terrible, everlasting punishment as certain or probable . . . Men base all these fears not on mature opinions, but on irrational fancies, that they are more disturbed by fear of the unknown than by facing facts. Peace of mind lies in being delivered from all these fears.

Men are so thoughtless, nay, so mad, that some, through fear of death, force themselves to die.

What men fear is not that death is annihilation but that it is not.

Remember that the future is neither ours nor wholly not ours, so that we may neither count on it as sure to come nor abandon hope of it as certain not to be.
