There are three kinds of minds: first those that attain insight and understanding of things by their own means, then those that recognize what is right when others explain it to them, and finally those that are capable of neither one nor the other.
Niccolo MachiavelliThere 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 MachiavelliMen are so simple of mind, and so much dominated by their immediate needs, that a deceitful man will always find plenty who are ready to be deceived.
Niccolo MachiavelliAny harm you do to a man should be done in such a way that you need not fear his revenge.
