Doubtful. The internet is chock full of these cuckoo quote sites. If Google doesn't yield a primary source, it's almost certainly fake. This is one area where absence of evidence really is evidence of absence.

Edit: not a criticism of the quote itself. These things wouldn't get misattributed if they weren't worth repeating. But they wouldn't get repeated if they weren't misattributed, either; it's a kind of cultural appeal to authority.
