Criticism is something you can easily avoid by saying nothing, doing nothing, and being nothing.
This time around it happened to be cited by the Tiny Buddha site - using the quote as a springboard for what proved in parts an interesting article - starting, of course, by parroting an erroneous attribution that just a few moments' casual research would have revealed as such.
Where does this quote actually come from? Why couldn't it be from Aristotle? Why would people unthinkingly accept and repeat that attribution. Even if it is not from Aristotle, is there some value to the saying? Those are some interesting questions that I'll answer below - though not in quite that order.
