“Technological civilization is man’s conquest of space. It is a triumph frequently achieved by sacrificing an essential ingredient of existence, namely, time. In technical civilization, we expend time to gain space. To enhance our power in the world of space is our main objective. Yet to have more does not mean to be more.

“To gain control of the world of space is certainly one of our tasks. The danger begins when in gaining power in the realm of space we forfeit all aspirations in the realm of time. There is a realm of time where the goal is not to have but to be, not to own but to give, not to control but to share, not to subdue but to be in accord. Life goes wrong when the control of space, the acquisition of things of space, becomes our sole concern.

“Nothing is more useful than power, nothing more frightful. We have often suffered from degradation by poverty, now we are threatened with degradation through power.

“The meaning of the Sabbath is to celebrate time rather than space. Six days a week we live under the tyranny of things of space; on the Sabbath we try to become attuned to holiness in time.

— Abraham Joshua Heschel, The Sabbath
