Family is central to Hellenismos, which certainly creates an odd situation for those who haven’t one. Some people are estranged from their parents and siblings (that would include myself), and others aren’t married and / or can’t have children by any means, and others simply don’t have children, for various reasons –the VHEMT subculture, while certainly at odds with the ancient ideal of marrying for the purpose of “creating legitimate offspring”, one called to the service of Gaia-Kybele, for example, might see the sense of avoiding procreation for environmental reasons.
A friend of mine who lives with her husband in Lesvos, Hellas, has her own child, but among her friends in the local HR community are those who don’t, and sees the issue as relatively simple to reconcile. It’s the old adage of “it takes a village to raise a child” sort of thinking: the lives of children are affected by everybody around them, not just their parents. There are teachers, doctors, nurses, babysitters, extended family, neighbours, family friends. Everybody, whether they realise it or not, affects that child’s upbringing.
This makes sense, if you think about the neurology involved. Sure, we’re only grazing the cap of foamed milk of understanding how the human mind works, but the leading theories all point to early development having a hand in at least 60% of our adult personalities. Some things are hardwired into the neural development, and rearing can only do so much with that, this is true, but so much of who we become is a direct result of early development, which is based on the people we’re exposed to. In that sense, our family extends considerably beyond those who share direct genetic material with us.
Family isn’t necessarily those who begat you. Procreation is certainly the easiest way to establish family, but ultimately family is the people you not only love and care about, but who affect you and you them. Family is the people who help you cultivate your psyche.
