Are you sure it was not that we were beginning to be something more? What does the beginning of manhood and womanhood mean in most people's mouths? You know: it means the beginning of love. But love began long before that for me. Love played its part in the earliest dreams and follies and romances I can remember--may I say the earliest follies and romances we can remember?--though we did not understand it at the time. No: the change that came to me was the birth in me of moral passion; and I declare that according to my experience moral passion is the only real passion. (ANN: All passions ought to be moral, Jack.) Ought! Do you think that anything is strong enough to impose oughts on a passion except a stronger passion still? (ANN: Our moral sense controls passion, Jack. Don't be stupid.) Our moral sense! And is that not a passion? Is the devil to have all the passions as well as all the good times? If it were not a passion--if it were not the mightiest of the passions, all the other passions would sweep it away like a leaf before a hurricane. It is the birth of that passion that turns a child into a man.
