Some years ago, I read that plants required 17 nutrients for growth and that growth was limited by whichever resource was most scarce. I’m not qualified to speak to the botany theory of that, but as a metaphor, I have wondered what the comparable 17 nutrients for human creativity would be (and how many there actually would be) and whether any of these common nutrients could be the limiting factor, or would they be ranked–the way Maslov ranked them–for our individualistic society at any rate?

What do you think?
