There are three different degrees to which we may allow a systematic theory of the world to embrace the idea of relatedness—supposing realism about non-symmetric relations as a background requirement. (First Degree) There are multiple ways in which a non-symmetric relation may apply to the things it relates—for the binary case, aRb ≠ bRa. (Second Degree) Every such relation has a distinct converse—for every R such that aRb there is another relation R* such that bR*a. (Third Degree) Each one of them applies in an order to the things it relates—with regard to the state that result from Rʼs applying to a and b, either R applies to a first and b second, or it applies to b first and a second. Whereas the first degree is near indubitable, embraci...
