"In oligarchies and democracies, the rulers have private interests, further they only meet occasionally and opportunities for action are missed; monarchs are continually occupied in the public interest. Again, the former are jealous and wish to exalt themselves at the expense of their predecessors and successors, the latter seek the good will of all. But the greatest difference is that monarchs treat public affairs as their own concern, other rules transact them as if they were other people's business, and they choose their advisors accordingly.
