explained that in prehistoric times, invention was a necessity, a movement to ensure humans could survive the elements. By the beginning of the Industrial Revolution, he noticed an obvious shift in the reason for invention: from necessity to that of the special interest of the state. By the 19th century again, the reason for invention changed to that of the special interest of the bourgeoisie who could see the profits that could be generated by the deliberate development of a technique. Since about the 1600s people have invested their money in stock in order to receive dividends; this practice became particularly attractive in the 20th century.
