The Invention (n.) is that which, in capitalism, has done nothing but endow material forces with intellectual life and degrade human life into a material force.
Invention (n.) is perfected not by the inventor but by the combined worker, whose experience alone discovers how to make it work in practice.
Invention (n.) must be made separately in each locality so long as no commerce goes beyond the immediate neighbourhood, and a barbarian irruption or an ordinary war can send an advanced country back to the beginning.
Invention (n.) always profits society far more than the inventor: the railway hands society 400 per cent and keeps 10.
Invention (n.) enriches society not with more exchange values but with more commodities for the same value, while competition drags the inventor's profit down to the general level.
Invention (n.) from 1825 onwards came almost wholly from collisions between the worker and the employer, and after each strike of any importance a new machine appeared.
Invention (n.) becomes a business once large industry is advanced and all the sciences have been pressed into the service of capital.
Invention (n.) of safety machinery will make remarkable progress the day manufacturers' own children must serve as factory assistants — till then, little children creep under moving mules to sweep the floor.
Invention (n.) can be forced into existence by law: the Factory Act made saving time a necessity, and so a match-dipping machine appeared whose phosphorus vapour no longer rose into boys' faces.
