What has not been examined impartially has not been well examined. Skepticism is therefore the first step towards truth.

Do you see this egg? With this you can topple every theological theory, every church or temple in the world.

You squander time as if you drew from a full and abundant supply, so all the while that day which you bestow on some person or thing is perhaps your last. You have all the fears of mortals and all the desires of immortals… What foolish forgetfulness of mortality to defer wise resolutions to the fiftieth or sixtieth year, and to intend to begin life at a point to which few have attained.
