If we open a quarrel between past and present we shall find that we have lost the future.

The stupid speak of the past, the wise of the present, and fools of the future.

Amid the vastness of the things among which we live, the existence of nothingness holds the first place; its function extends over all things that have no existence, and its essence, as regards time, lies precisely between the past and the future, and has nothing in the present.

I don't carry the burden of the past or the madness of the future. I live in the present.

I try to learn from the past, but I plan for the future by focusing exclusively on the present. That's where the fun is.

The future is unknowable, but the past should give us hope.
