“ I’ve always resented the word maturity, primarily, I think, because it is most often used as a club. If you do something that someone doesn’t like, you lack maturity, regardless of the actual merits of your action. Too, it seems to me that what is most often called maturity is nothing more than disengagement from life. If you meet life squarely, you are likely to make mistakes, do things you wish you hadn’t, say things you wish you could retract or phrase more felicitously, and, in short, fumble your way along. Those “mature” people whose lives are even without a single sour note or a single mistake, who never fumble, manage only at the cost of original thought and original action. They do without the successes as well as the failures. This has never appealed to me and that is another reason I could never accept the common image of maturity that was presented to me.It was only after I came back from Trial that I came to a notion of my own as to what maturity consists of. Maturity is the ability to sort the portions of truth from the accepted lies and self-deceptions that you have grown up with. It is easy now to see the irrelevance of the religious wars of the past, to see that capitalism in itself is not evil, to see that honor is most often a silly thing to kill a man for, to see that national patriotism should have meant nothing in the twenty-first century, to see that a correctly-arranged tie has very little to do with true social worth. It is harder to assess as critically the insanities of your own time, especially if you have accepted them unquestioningly for as long as you can remember, for as long as you have been alive. If you never make the attempt, whatever else you are, you are not mature. ”
