Tautologies in action


A bare tautology like “Business is business”, as a free-standing statement, invite contentful interpretation via a “Gricean implicature” (specifically, the Maxim of Quantity).   The following is a syntactically more complex case, where the tautology is embedded in a subordinate clause:

Ever since self was self, nature been keepin’ folks off of red-hot stoves.
-- Zora Neale Hurston, Their Eyes Were Watching God (1937)

The meaning is:  Common sense has been extant  from time immemorial.  Operationally, the (tongue-in-cheek) interpretation is:  Go back and back in time, sampling as you go. For each sample-point, verify whether  “self = self” holds at that time; and if so, then evaluate “Common Sense is in effect? Y/N”.   If the answer is Yes each time, then the corelation holds.
The sentence, for all its folksiness, has a kind of philosophy-class spin to it; the moreso as “self = self” calls up First-Order Logic with Identity.
