Possibly when the professor insisted a little too emphatically upon the inferiority of women, he was concerned not with their inferiority, but with his own superiority. That was what he was protecting rather hot-headedly and with too much emphasis, because it was a jewel to him of the rarest price. Life for both sexes--and I looked at them, shouldering their way along the pavement--is arduous, difficult, a perpetual struggle. It calls for gigantic courage and strength. More than anything, perhaps, creatures of illusion as we are, it rails for confidence in oneself. Without self-confidence we are as babes in the cradle. And how can we generate this imponderable quality, which is yet so invaluable, most quickly? By thinking that other people are inferior to oneself. By feeling that one has some innate superiority--it may be wealth, or rank, a straight nose, or the portrait of a grandfather by Romney--for there is no end to the pathetic devices of the human imagination--over other people.
