The economy of human time is the next advantage of machinery in manufactures.
A tool is usually more simple than a machine; it is generally used with the hand, whilst a machine is frequently moved by animal or steam power.
At each increase of knowledge, as well as on the contrivance of every new tool, human labour becomes abridged.
The fatigue produced on the muscles of the human frame does not altogether depend on the actual force employed in each effort, but partly on the frequency with which it is exerted.
A powerful attraction exists, therefore, to the promotion of a study and of duties of all others engrossing the time most completely, and which is less benefited than most others by any acquaintance with science.
