Lorenz describes — T Clark

This system thus exists a priori to the extent that it is present before the individual experiences anything, and must be present if experience is to be possible. But its function is also historically evolved and in this respect not a priori. — Lorenz - Behind the Mirror

If I'm understanding that right, then Lorenz is saying (at least in part) that what is a priori to the individual is a posteriori to the race, or species?

I suspect I'm not using the quote mechanism correctly; I meant to quote T Clark, quoting Lorenz.

Well, I have to jump in somewhere; let this be the pond!

• Recently finished Jeff McMahan, The Ethics of Killing: Problems at the Margins of Life. Except not really finished, because I have to go back and take notes on the parts where I think he goes wrong.
  
• Christine Korsgaard, The Sources of Normativity.
  
• Thomas Aquinas, Commentary on Aristotle's Physics, trans. R J Blackwell, R. J. Spath, W. D. Thirlkel, intro. by V. J. Bourke. London: Routledge & Kegan Paul, 1963. From this edition I have learned that the Latin translation of Aristotle's Physics which typically appears in the Latin version of Thomas's commentary, is not the translation that Aquinas used, but a later translation from Renaissance times.
  
• Moved by the dialog mentioned in Count Timothy von Icarus's discussion Semiotics and Information Theory, I began reading John Deely's New Beginnings: Early Modern Philosophy and Postmodern Thought. But that turned out to be over my head, so I have laid it aside in favor of Thomas Sebeok's Signs: An Introduction to Semiotics, the second edition, 2021.

It's been a long while since I've read any of Pratchett, but I think you can read his books in any order. He always takes some time to give basic background. So start anywhere, and enjoy!
