Niccolò Machiavelli said this quote

And here comes in the question whether it is better to be loved rather than feared, or feared rather than loved. It might perhaps be answered that we should wish to be both; but since love and fear can hardly exist together, if we must choose between them, it is far safer to be feared than loved.

~ Niccolò Machiavelli

The first method for estimating the intelligence of a ruler is to look at the men he has around him.

~ Niccolò Machiavelli

Because there are three classes of intellects: one which comprehends by itself; another which appreciates what others comprehend; and a third which neither comprehends by itself nor by the showing of others; the first is the most excellent, the second is good, the third is useless.

~ Niccolò Machiavelli

A prudent man should always follow in the path trodden by great men and imitate those who are most excellent, so that if he does not attain to their greatness, at any rate he will get some tinge of it.

~ Niccolò Machiavelli
