“Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.”
III, 10
Meditations (c. 121–180 AD), Book III
Context: Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed. Short, therefore, is man's life, and narrow is the corner of the earth wherein he dwells.

Variant: Life can be found only in the present moment. The past is gone, the future is not yet here, and if we do not go back to ourselves in the present moment, we cannot be in touch with life.
