The past cannot be changed. The future is yet in your power.

We must respect the past, and mistrust the present, if we wish to provide for the safety of the future.

The future is called 'perhaps,' which is the only possible thing to call the future. And the important thing is not to allow that to scare you.

There is always one moment in childhood when the door opens and lets the future in.

I touch the future. I teach.

The past, the present and the future are really one: they are today.

I know not why there is such a melancholy feeling attached to the remembrance of past happiness, except that we fear that the future can have nothing so bright as the past.

Enjoy present pleasures in such a way as not to injure future ones.

The wise man must remember that while he is a descendant of the past, he is a parent of the future.

For all of its uncertainty, we cannot flee the future.
