“As the past has ceased to throw its light upon the future, the mind of man wanders in obscurity.”

Context: The first thing necessary for a constructive dealing with time is to learn to live in the reality of the present moment. For psychologically speaking, this present moment is all we have. The past and future have meaning because they are part of the present: a past event has existence now because you are thinking of it at this present moment, or because it influences you so that you, as a living being in the present, are that much different. The future has reality because one can bring it into his mind in the present. Past was the present at one time, and the future will be the present at some coming moment. To try to live in the "when" of the future or the "then" of the past always involves an artificiality, a separating one's self from reality; for in actuality one exists in the present. The past has meaning as it lights up the present, and the future as it makes the present richer and more profound.

Original: (it) Il passato ha concluso il suo tempo, il presente è l'attimo, il futuro il divenire.

Context: I said earlier that I do not believe an artist's life throws much light upon his works. I do believe, however, that, more often than most people realize, his works may throw light upon his life. An artist with certain imaginative ideas in his head may then involve himself in relationships which are congenial to them.
