(Funnily enough, the earliest version of DnD only had a one-axis, three-point system of alignment: you could serve Law, Chaos, or Neutrality, with no Good or Evil to be seen. This is obviously cribbed off of Michael Moorcock, whose books involved a cosmic balance between Law and Chaos, and who tried, though not always successfully, to divorce those concepts from the easier binary of good versus evil.
This is very true. It is also possible that these concepts are much older than Moorcock ... Maat vs. Isfet.
