In order to fulfil the duties of life, and to be able to pursue with vigour the various employments which form the moral character, a master and mistress of a family ought not to continue to love each other with passion. I mean to say that they ought not to indulge those emotions which disturb the order of society, and engross the thoughts that should be otherwise employed. The mind that has never been engrossed by one object wants vigour -- if it can long be so, it is weak.
A mistaken education, a narrow, uncultivated mind, and many sexual prejudices, tend to make women more constant than men; but, for the present, I shall not touch on this branch of the subject. I will go still further, and advance, without dreaming of a paradox, that an unhappy marriage is often very advantageous to a family, and that the neglected wife is, in general, the best mother. And this would almost always be the consequence if the female mind were more enlarged: for, it seems to be the common dispensation of Providence, that what we gain in present enjoyment should be deducted from the treasure of life, experience; and that when we are gathering the flowers of the day and revelling in pleasure, the solid fruit of toil and wisdom should not be caught at the same time. The way lies before us, we must turn to the right or left; and he who will pass life away in bounding from one pleasure to another, must not complain if he acquire neither wisdom nor respectability of character.
