Criticism

An early opponent of the family was Socrates whose position was outlined by Plato in The Republic. In Book 5 of The Republic, Socrates tells his interlocutors that a just city is one in which citizens have no family ties.

The Russian-American rationalist and individualist philosopher, novelist and playwright Ayn Rand compared partiality towards consanguinity with racism, as a small-scale manifestation of the latter. "The worship of the family is merely racism, like a crudely primitive first installment on the worship of the tribe. It places the accident of birth above a man's values and duty to the tribe above a man's right to his own life." Additionally, she spoke in favor of childfree lifestyle, while following it herself.
