Would you accept to be challenged with a quote of an older writer and philosopher?

There are three kinds of intelligence: one kind understands things for itself, the other appreciates what others can understand, the third understands neither for itself nor through others. This first kind is excellent, the second good, and the third kind useless. Niccolo Machiavelli ---------------------------------- Agree? Disagree? Some examples maybe? Where would you place Alexander the Great? Einstein? Christ? Aristotle? Nietzsche? A famous actor/ress. A famous singer. Yourself.
