“It is man’s ideas that have evolved and changed the world about him. Now, confronted by the lethal radiations of open space and the fantastic speeds of his machines, he has to invent new electronic controls that operate faster than his nerves, and he must shield his naked body against atomic radiation by the use of protective metals. Already he is physically antique in this robot world he has created. All that sustains him is that small globe of gray matter which spin his ever-changing conceptions of the universe.”
