“The development of the telescope marks, indeed, a new phase in human thought, a new vision of life. It is an extraordinary thing that the Greeks, with their lively and penetrating minds, never realized the possibilities of either microscope or telescope. They made no use of the lens. Yet they lived in a world in which glass had been known and had been made beautiful for hundreds of years; they had about them glass flasks and bottles, through which they must have caught glimpses of things distorted and enlarged. But science in Greece was pursued by philosophers in an aristocratic spirit, men who, with a few such exceptions as the ingenious Archimedes and Hiero, were too proud to learn from such mere artisans as jewellers and metal- and glass-workers.Ignorance is the first penalty of pride. The philosopher had no mechanical skill and the artisan had no philosophical education, and it was left for another age, more than a thousand years later, to bring together glass and the astronomer.(The Earth in Space and Time §1)”
