We can understand how a knight in the age of chivalry could want to sacrifice his life for the honor of a princess he had never so much as spoken to — this was an especially thrilling idea to me when I was about eleven or twelve — but it is not a state of mind into which an adult today can readily enter. People used to talk and think about love in ways that are now practically unavailable — except to children, and to those who can somehow suppress their adult knowledge. […] It is no longer possible for sophisticated people to “fall in love” in some of the ways that once were possible — simply because they cannot believe in those ways of falling in love. It is not possible for me, for instance, to have a pure teenaged crush — unless I “revert to adolescence” and in the process forget or abandon much of what I think I know.
– Daniel Dennett, Consciousness Explained (1991)
