The uncertainty and importance of the present reduce the past and future to comparative insignificance, and clear the mind of minor worries. And when all is over, memories remain which few men do not hold precious.

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.

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

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

I don't think the human mind can comprehend the past and the future. They are both just illusions that can manipulate you into thinking there's some kind of change.
