Adam Smith

"Virtue is more to be feared than vice, because its excesses are not subject to the regulation of conscience."

"The subjects of every state ought to contribute toward the support of the government in proportion to their respective abilities; that is, in proportion to the revenue which they respectively enjoy under the protection of the state. The expense of government to the individuals of a great nation is like the expense of management to the joint tenants of a  great estate, who are all obliged to contribute in proportion to their respective interests in the state."
