Louis Mumford noticed that the clock creates the idea of moment to moment. He says clocks are metaphors which we are not educated to recognize. He realized that the clock’s product is seconds and minutes and has the effect of disassociating time from human events and thus nourishes the belief in an independent world of mathematically measurable sequences. The clock, invented in the 14th century, made us time-keepers, then time-savers, and now time servers. In a world made up of seconds and minutes the authority of nature is superseded. With the invention of the clock eternity ceased to be the focus of human beings. Belief in God’s supremacy is weakened with every ticking second. Perhaps that was what the God that spoke to Moses on Sinai also meant by “graven images.”
