The truth of the matter is that the family naturally and spontaneously arises whenever human beings unite together in society. If someone were to try to invent the best system for fulfilling children’s basic needs and development, the answer would be the two-parent family. The family is not a social construct; it is an institution that corresponds to human nature and design.
Regarding the family, natural law expert Prof. J. Budiszewski writes: “No one invented it, no one is indifferent to it, and there never was a time in human history when it did not exist. Even when disordered, it persists. Members who are divided by disaster commonly undertake heroic efforts to reunite with each other. Only violence or strong ideology can abolish the family, and only small societies have even tried to abolish it; those which do tryalways fail or else retreat gradually from their aims” (J. Budziszewski, What We Can’t Not Know: A Guide, Ignatius Press, San Francisco, 2011, p. 98).
