I've came across the phrase (arithmetic promise) and I was confused by the word (promise) here. What does it mean in the following context.
Buddhism begins with the “Four Noble Truths,” but their brevity is deceptive. The first three are one- liners: life is suffering; the source of suffering is attachment; the goal is to give it up. The fourth noble truth is an “Eightfold Path”— which rather defeats the arithmetic promise. (How many noble truths are there, in fact? Eleven? Or more, if some of the eight turn out to be more than one?)
Thank you in advance!
