Socially the clock had a more radical influence than any other machine, in that it was the means by which the regularization and regimentation of life necessary for an exploiting system of industry could best be attained. The clock provided the means by which time - a category so elusive that no philosophy has yet determined its nature - could be measured concretely in more tangible forms of space provided by the circumference of a clock dial. Time as duration became disregarded, and men began to talk and think always of "lengths" of time, just as if they were talking of lengths of calico. And time, being now measurable in mathematical symbols, became regarded as a commodity that could be bought and sold in the same way as any other commodity.
