But the husband and wife, though they have but one common concern, yet having different understandings, will unavoidably sometimes have different wills too; it therefore being necessary that the last determination, i.e. the rule, should be placed somewhere; it naturally falls to the man’s share, as the abler and the stronger. But this reaching but to the things of their common interest and property, leaves the wife in the full and free possession of what by contract is her peculiar right, and gives the husband no more power over her life than she has over his; the power of the husband being so far from that of an absolute monarch, that the wife has in many cases a liberty to separate from him, where natural right or their contract allows it; whether that contract be made by themselves in the state of nature, or by the customs or laws of the country they live in; and the children upon such separation fall to the father’s or mother’s lot, as such contract does determine.
