I don’t try to describe the future. I try to prevent it.

Every man takes the limits of his own vision for the limits of the world.

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

The future is no more uncertain than the present.

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

Destiny is not a matter of chance, it is a matter of choice; it is not a thing to be waited for, it is a thing to be achieved.

I’ve seen the future, brother; it is murder.

As natural selection works solely by and for the good of each being, all corporeal and mental endowments will tend to progress toward perfection.

The future comes like an unwelcome guest.

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

The world began without man, and it will end without him.

Time will reveal everything. It is a babbler and speaks even when not asked.

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