'
There are two kinds of fools: one says, "This is old, therefore it is good"; the other says, "This is new, therefore it is better."' -
William Ralph Inge
Just because something is old doesn't mean it's good, but neither does that mean that it isn't good either. Don't use age of an idea to say it's invalid, nor use it to say that it must be right because it's lasted. If anything, what was
intended is even more important IMO than what it actually says, but I may be in the minority there. Is the Canadian constitution "more valid" because it was updated in 1982, or not? I'd say not, but age has nothing to do with it (stupid clauses do, but that's another discussion).
