Does “God is everything” mean “there is no God”?
Does “I love everyone” mean “I love no one”?
Does “It’s all good” mean “nothing is good”?
Maybe! It could be that we only have words like “true”, “love”, and “God” to pick out certain situations or aspects of reality as worthy of trust, love, faith or worship. If so that would mean that applying these words globally means nothing is worth picking out as especially worthy of these attitudes.
If this were true one of our requirements of a meaningful speech act is that it runs some risk. That is, we want to say to the person talking about truth, if there is no chance you are wrong, don’t waste my time. You need, as they say, to have skin in the game. You need to run the risk of misleading me for me to bother even considering following you.
