The present (or now) is the time range associated with the events perceived directly for the first time, not as a recollection (perceived more than once) or a speculation (predicted, hypothesis, uncertain). It is a period of time between the past and the future, and can vary in meaning from an instant to a day or longer. It is sometimes represented as a hyperplane in space-time, typically called "now", although modern physics demonstrates that such a hyperplane cannot be defined uniquely for observers in relative motion.
- The Now, that indivisible point which studs the length of infinite line
Whose ends are nowhere, is thine all, the puny all thou callest thine.
- If you are living in the past or in the future, you will never find a meaning in the present.

- The present is nothing else than the sum of what one perceives, remembers and hopes for.

- The present is an infinitesimal between two infinites. 'Tis a line (a thing without breadth or thickness) moving across the surface of Eternity. The present is no more, by the time you have said, This is present.
- Henry Harland, The Lady Paramount (1902), Ch. VII.
- Today is only one day in all the days that will ever be. But what will happen in all the other days that ever come can depend on what you do today. It's been that way all this year. It's been that way so many times. All of war is that way.
- We are always acting on what has just finished happening. It happened at least 1/30th of a second ago. We think we’re in the present, but we aren’t. The present we know is only a movie of the past.
- Ken Kesey, As quoted by Tom Wolfe in The Electric Kool-Aid Acid Test (1968) Ch. 11
- The dogmas of the quiet past, are inadequate to the stormy present.

Let the dead Past bury its dead!
Act, — act in the living Present!
Heart within, and God o’erhead!

- Don’t shortchange the future, because of fear in the present.
