Epictetus on children and marriage

Foucault, The Care of the Self, p. 155:

[Epictetus] refers to the social obligations that no man must shirk and of which marriage forms a part, alongside the duties that pertain to political life, religion, and the family: 'citizenship, marriage, procreation of children, worship of God, care of parents.'

But not really. On page 156 Foucault says "it was the same with marriage as with all the other practices that the Stoics classed among the proegoumena, the things that are preferable. There may be circumstances in which it is not obligatory."
