A change of fortune hurts a wise man no more than a change of the moon.

Not a change for the better in our human housekeeping has ever taken place that wise and good men have not opposed it—have not prophesied that the world would wake up to find its throat cut in consequence.

The less a man knows about the past and the present, the more insecure must prove to be his judgment of the future.

The world is dying of machinery; that is the great disease, that is the plague that will sweep away and destroy civilization; man will have to rise against it sooner or later.

Tomorrow never comes, man. It’s all the same fucking day.

People will not look forward to posterity who never look backward to their ancestors.

Little folks become their little fate.

It would be madness, and inconsistency, to suppose that things which have never yet been performed can be performed without employing some hitherto untried means.

Real generosity toward the future lies in giving all to the present.

All progress is based upon a universal, innate desire on the part of every organism to live beyond its income.

Every saint has a past, and every sinner has a future.

The future, like everything else, is no longer quite what it used to be.

The future is no more uncertain than the present.
