Quote of the Day (Oliver Sacks, on Why We Speak)

“We speak not only to tell other people what we think, but to tell ourselves what we think. Speech is a part of thought.”— British-born American neurologist, naturalist, and historian of science Oliver Sacks (1933-2015), Seeing Voices: A Journey into the World of the Deaf (1989)
