These reasonings are unconnected: "I am richer than you, therefore I am better"; "I am more eloquent than you, therefore I am better." The connection is rather this: "I am richer than you, therefore my property is greater than yours;" "I am more eloquent than you, therefore my style is better than yours." But you, after all, are neither property nor style.
EpictetusAs you think, so you become.....Our busy minds are forever jumping to conclusions, manufacturing and interpreting signs that aren't there.
