I don't think this is accurate either -- some people do peak early in life. I can't think of good philosopher examples right now, but there are a couple of examples and possible causes of the phenomenon in this article [1].
That being said it may very well be particularly people who deal with very fundamental problems, such as philosophers, often get better with age.
In any case it's probably best to refrain from making general statements about people based solely on age.
