If I don't do what my husband tells me, I will get spanked. Now I don't find this an unpleasant prospect at all, so why it should make me more obedient I don't really know, I only know that it does.
And although I do feel that his authority is real, in the sense that I feel a compulsion to obey him even though I know I don't really have to, it can't feel the same as it does to a woman who lives in a society where women are compelled by law and by society to obey their husbands, or else.
Of course, the threat of unpleasant consequences is not the only thing that makes people respect authority. Most employees do what their boss wants because they want to get on in their job, not because they're afraid of getting sacked. I get my children to school because I know they need to get an education, not because I know I could end up in the nick if I don't.
I don't obey my husband because he will spank me if I don't, but because I feel that mysterious compulsion to obey him when he speaks to me in a certain tone of voice. It is real, and yet it is pleasurable, which is not the case with all forms of obedience. I don't resent his authority the way I might do if it was thrust upon me whether I liked it or not.
