It is often said that religion gives meaning to otherwise meaningless things. I’m of two minds about the claim. On the one hand, religion doesn’t add information in the sense of giving you more facts about the universe than you had without religion. On the other hand, it certainly is true that if a person speaks in religious code, familiarity with the religion certainly helps decipher quite a lot.
My tendency, though, is to come down on the side of those who believe it is false to say that religion gives meaning to otherwise meaningless things. This is because knowing the religious codes and conventions does not require actual belief.
