Is your brain completely furnished?
“The brain conducts a busy telephone exchange with a central office and many branches.... But can you find love or hate, fear or joy anywhere about the premises?” The caption ends with a quote (slightly mis-quoted actually, or so Wikiquote informs me) from Shakespeare’s “Merchant of Venice”, Act III:
"Where, oh where is fancy bred?
Or in the heart, or in the head?”
