You may decry some of these scruples and protest that there are more things in heaven and earth than are dreamt of in my philosophy. I am concerned, rather, that there should not be more things dreamt of in my philosophy than there are in heaven or earth.
Nelson Goodman (b. 1906), U.S. philosopher, art dealer. Fact, Fiction & Forecast, ch. 2, p. 39 (1955).
Cf., of course, Shakespeare's Hamlet, I, v, 166 "There are more things in heaven and earth, Horatio, than are dreamed of in your philosophy," but also J.B.S. Haldane's Possible Worlds, "I suspect that there are more things in heaven and earth than are dreamed of in any philosophy."
