Welcome to Astral Codex Ten! Some of you are probably veterans of my old blog, Slate Star Codex. Others may be newbies wondering what this is all about.

I'm happy to finally be able to give a clear answer: this is a blog about ṛta.

Ṛta is a Sanskrit word, so ancient that it brushes up against the origin of Indo-European languages. It's related to English "rationality" and "arithmetic", but also "art" and "harmony". And "right", both in the senses of "natural rights" and "the right answer". And "order". And "arete" and "aristos" and all those other Greek words about morality. And "artificial", as in eg artificial intelligence. More speculatively "reign" and related words about rulership, and "rich" and related words about money.

(also "arthropod", but insects creep me out so I'll be skipping this one)
