“When we are young we believe to be adults; when we are adults we believe to be young.”

Interview with Oriana Fallaci as reported in The Chicago Tribune (24 June 1973) (Excerpts online) http://www.jah-rastafari.com/selassie-words/show-jah-word.asp?word_id=int_ori.
Context: It is obvious that We have been young. We weren't born old! We have been a child, a boy, a youth, an adult, and finally an old man. Like everyone else. Our Lord the Creator made us like everyone else. Maybe you wish to know what kind of youth We were. Well We were a very serious, very diligent, very obedient youth. We were sometimes punished, but do you know why? Because what We were made to study did not seem enough and We wished to study further. We wanted to stay on at school after lessons were over. We were loath to amuse ourselves, to go riding, to play. We didn't want to waste time on games.

McKenna interview (1992)
Context: I love child things because there's so much mystery when you're a child. When you're a child, something as simple as a tree doesn't make sense. You see it in the distance and it looks small, but as you go closer, it seems to grow — you haven't got a handle on the rules when you're a child. We think we understand the rules when we become adults but what we really experienced is a narrowing of the imagination.
