There is not even a thought, or an invention, which is not common property, born of the past and the present. Thousands of inventors, known and unknown, who have died in poverty, have co-operated in the invention of each of these machines which embody the genius of man.
Thousands of writers, of poets, of scholars, have laboured to increase knowledge, to dissipate error, and to create that atmosphere of scientific thought, without which the marvels of our century could never have appeared. And these thousands of philosophers, of poets, of scholars, of inventors, have themselves been supported by the labour of past centuries. They have been upheld and nourished through life, both physically and mentally, by legions of workers and craftsmen of all sorts. They have drawn their motive force from the environment.
…Science and industry, knowledge and application, discovery and practical realization leading to new discoveries, cunning of brain and of hand, toil of mind and muscle — all work together. Each discovery, each advance, each increase in the sum of human riches, owes its being to the physical and mental travail of the past and the present.
By what right then can any one whatever appropriate the least morsel of this immense whole and say — This is mine, not yours?
