But what if someone does not like the consequences of adopting a given logical principle? What if conversational or social practices change? If the rules of logic and language are conventional, what is to stop someone, for whatever reason, from adopting different conventions? Absolutely nothing. The rules of logic and grammar then can be as variable as other conventions, such as performing greeting rituals by shaking hands, hugging, or rubbing noses. No form of greeting or system of logic, then, is more objectively right than any other.
