I know I am repeating myself and JS here, but I think the answer to Mill’s question: What must be the effect on his character , of this lesson?… is that the effect is a pathological emotional dissonance of fearful insecurity which at it’s worst can express itself in pedophilia.
All the selfish propensities, the self-worship, the unjust self-preference, which exist among mankind, have their source and root in, and derive their principal nourishment from, the present constitution of the relation between men and women. Think what it is to a boy, to grow up to manhood in the belief that without any merit or any exertion of his own, though he may be the most frivolous and empty or the most ignorant and stolid of mankind, by the mere fact of being born a male he is by right the superior of all and every one of an entire half of the human race: including probably some of whose real superiority to himself he has daily or hourly occasion to feel; but even if in his whole conduct he habitually follows a woman’s guidance, still, if he is a fool, she thinks that of course she is not, and cannot be, equal in ability and judgment to himself; and if he is not a fool, he does worse – he sees that she is superior to him, and believes that notwithstanding her superiority, he is entitled to command and she is bound to obey. What must be the effect on his character , of this lesson?…… The principle of the modern movement in morals and politics, is that conduct, and conduct alone, entitles to respect: that not what men are, but what they do, constitutes their claim to deference; that, above all, merit, and not birth, is the only rightful claim to power and authority.
