Famous quotes containing the word science:
“It is not too much to say that next after the passion to learn there is no quality so indispensable to the successful prosecution of science as imagination. Find me a people whose early medicine is not mixed up with magic and incantations, and I will find you a people devoid of all scientific ability.”
—Charles Sanders Peirce (1839–1914)
“Everything is becoming science fiction. From the margins of an almost invisible literature has sprung the intact reality of the 20th century.”
—J.G. (James Graham)
