Fromm's next step?

I'm just shopping for courses at Hebrew U. right now, and tonight I sat in on a course taught by Jonathan Cohen, one of the great scholars of Jewish educational philosophy (and he kind of looks like one of the Star Trek aliens from DS9 though I can't find the link - and a little less like this one).

Here's the line of thinking that might be worth sharing. According to Cohen, Erich Fromm (most famous for The Art of Loving, though I'm quite sure this thinking is not found there), believed in a progressive approach to the development of human civilization based on three stages in an individual's human development, from a baby reliant on its mother emotionally, to a child who makes a deal [covenant] with his father cognitively, to an autonomous young-adult/teen who rejects his relationship with his parents. This is interesting in and off itself, and has implications for thinking about the development of maternal goddesses (who may have just given of themselves and of the earth) and paternal gods (who could get angry) and helps to explain the throwing off of God by civilization since the Scientific Revolution (or Enlightenment, take your pick). But Fromm, again according to Cohen, did not take this one step further - evidently, philosophers (like Fromm, Marx, and more), not being prophets, stop at explaining the history of the world in their own era.

Here's my חידוש:

If we hold by Fromm (loosely, at least), then it would make sense that the fourth stage is not a return to reliance on other individuals (i.e., moving back into your parents' house post-college) but instead the acceptance of your own responsibility for more than yourself - what we might call parenthood. Under such a read, imagine the 3rd era of development (which, under my theory, is quickly moving into our rear-view mirror) as encompassing the last five hundred years or so, when humanity ran roughshod over each other, the planet, and everything that came in our way. Civilization, then, has acted as the irresponsible teenager, obsessed with his own autonomy but negligent of the responsibilities that should be associated with it. Then, the next stage of human history should involve us getting our act together, moving from the orgiastic instincts of the past to a shepherding of each other and the rest of the world (including endangered animals and the environment, chiefly). Is such a move in the offing? Perhaps. But I think, from a Frommian perspective, this is a compelling read towards the type of social entrepreneurship and return to caring about environmental issues we've seen in the past little slice of history.

Here's hoping we're ready to be parents.
