===Commentary Note 12.2===
The logic of selective terms is something of a lost art these days, the current thinking in logic being to regard the complete proposition as the quantum of discourse, ''ne plus infra''. With absolute terms, or monadic relatives, and the simpler operations on dyadic relatives, the necessary translations between propositions and terms are obvious enough, but when it comes to higher adic relatives and operations as complex as exponentiation, it will be useful to stop and consider the links between these two languages.
The logic of selective terms is something of a lost art these days, when the current thinking in logic tends to treat the complete proposition as the quantum of discourse, ''ne plus infra''. With absolute terms, or monadic relatives, and the simpler operations on dyadic relatives, the necessary translations between propositions and terms are obvious enough, but now that we've reached the threshold of higher adic relatives and operations as complex as exponentiation, it is useful to stop and consider the links between these two languages.
The term ''exponentiation'' is more generally used in mathematics for operations that involve taking a base to a power, and is slightly preferable to ''involution'' since the latter is used for different concepts in different contexts. Operations analogous to taking powers are widespread throughout mathematics and Peirce frequently makes use of them in a number of important applications, for example, in his theory of information. But that's another story.
