"For those interested in revolt (as I am) I only say meekly that one cannot have a Revolution without revolving."

A wheel is the sublime paradox; one part of it is always going forward and the other part always going back. Now this, as it happens, is highly similar to the proper condition of any human soul or any political state. Every sane soul or state looks at once backwards and forwards; and even goes backwards to come on.

For those interested in revolt (as I am) I only say meekly that one cannot have a Revolution without revolving. The wheel, being a logical thing, has reference to what is behind as well as what is before. It has (as every society should have) a part that perpetually leaps helplessly at the sky and a part that perpetually bows down its head into the dust. Why should people be so scornful of us who stand on our heads? Bowing down one's head in the dust is a very good thing, the humble beginning of all happiness. When we have bowed our heads in the dust for a little time the happiness comes; and then (leaving our heads in the humble and reverent position) we kick up our heels behind in the air. That is the true origin of standing on one's head; and the ultimate defence of paradox. The wheel humbles itself to be exalted; only it does it a little quicker than I do.

Also, the following is a quote from earlier in the same essay in that book:

Men, they say, are now imitating angels; in their flying-machines, that is: not in any other respect that I have heard of.
