Lila (1991)
Context: Any person of any philosophic persuasion who sits on a hot stove will verify without any intellectual argument whatsoever that he is in an undeniably low-quality situation: that the value of his predicament is negative. This low quality is not just a vague, woolly-headed, crypto-religious, metaphysical abstraction. It is an experience. It is not a judgment about an experience. It is not a description of experience. The value itself is an experience. As such it is completely predictable. It is verifiable by anyone who cares to do so. It is reproducible.

“The way of truth is along the path of intellectual sincerity.”
Address to students, quoted in Abraham Flexner, Henry S. Pritchett: A Biography (Columbia University Press, 1943; University of Virginia digitization, May 2, 2008, 211 pages), p. 192
