The inverse relationship between symmetry and diversity — that we see for example
in the lattice-inverting map of a Galois correspondence — is a variation on an old
theme in logic called the “inverse proportionality of comprehension and extension”.

C.S. Peirce, in his probings of the “laws of information”,
found this principle to be a special case of a more general
formula, saying that the reciprocal relation holds only when
the quantity of information is constant.
