I have wanted to emphasize the goodness of life, in spite of the fact that many things are wrong in the world. But what is “life”? I don’t have a completely satisfying answer, but I do have a few thoughts.
Nature is said in many ways, of course, and these yield different perspectives on life from the side of nature. In an evolutionary context, I prefer to stress the marvelous diversification of organic forms over competition between individuals or species. Life, I think, is better understood in terms of purposes and what Aristotle calls “that for the sake of which”, than by attempting to reduce it to elements and efficient causes. All those purposes are intrinsic to the nature of the things that have them, and indeed they constitute that nature.
It does not make sense to inquire about “the” meaning of life. Rather, life is meaning, in superabundance and overflow. We should look at life not in terms of minimal biological prerequisites, but in terms of its highest development in each of the many kinds that flourish. That is the real significance of Aristotelian and Hegelian “actuality”.
