James Q. Wilson now at the American Enterprise Institute in Washington D.C. wrote “The Marriage Problem” to convey how the West has moved away from viewing marriage as a religious covenant. Some excerpts here:
The Enlightenment has weakened marriage in that it has replaced a sacrament with a contract as an arrangement. The enlightenment ethos of individualism has now degraded itself into radical autonomy creating conflicts which both the enlightenment itself nor its ethos can resolve. The problem can be stated as follows: how can women be introduced into the workplace (emancipated) without undermining the family, the bond of marriage or the status of children? It seems that the enlightenment ethos has severed a natural complementary distinction in favor of narcissism.
The only way toward a peaceful resolution is to restore objective moral criteria into both our relations between spouses and a system of taxation in favor of women and children.
