"Subjection is twofold. One is servile, by virtue of which a superior makes use of a subject for his own benefit; and
this kind of subjection began after sin. There is another kind of subjection, which is called economic or civil, whereby
the superior makes use of his subjects for their own benefit and good; and this kind of subjection existed even before
sin. For the good of order would have been wanting in the human family if some were not governed by others wiser
than themselves. So by such kind of subjection woman is naturally subject to man, because in man the discernment of
reason predominates."
