Value truth because it is true, not because it is novel.

Its easy to always be learning, always be seeking some new morsel of knowledge, and to take your greatest delight in things because you did not know them before. Denigrating what you already know, becoming bored with it, and unfairly valuing the new things you learn. This can lead to an unhealthy discontentment with things you already know, feeling that you must always be adopting some new position on things. Sometimes, things that we have known for a very long time are far more true than things we learned today. We should value the truths we know because they are true, not because we didn't know them before.
