In a government framed for durable liberty, not less regard must be paid to giving the magistrate a proper degree of authority, to make and execute the laws with rigour, than to guarding against encroachments upon the rights of the community. As too much power leads to despotism, too little leads to anarchy, and both eventually to the ruin of the people.

The inquiry constantly is what will please, not what will benefit the people. In such a government there can be nothing but temporary expedient, fickleness, and folly.

Were not the disadvantages of slavery too obvious to stand in need of it, I might enumerate and describe the tedious train of calamities inseparable from it. I might show that it is fatal to religion and morality; that it tends to debase the mind, and corrupt its noblest springs of action. I might show that it relaxes the sinews of industry, clips the wings of commerce, and introduces misery and indigence in every shape.

Constitutions of civil government are not to be framed upon a calculation of existing exigencies, but upon a combination of these with the probable exigencies of ages, according to the natural and tried course of human affairs. Nothing, therefore, can be more fallacious than to infer the extent of any power, proper to be lodged in the national government, from an estimate of its immediate necessities.

It is an unquestionable truth, that the body of the people in every country desire sincerely its prosperity. But it is equally unquestionable that they do not possess the discernment and stability necessary for systematic government. To deny that they are frequently led into the grossest of errors, by misinformation and passion, would be a flattery which their own good sense must despise.

There is no position which depends on clearer principles than that every act of a delegated authority, contrary to the commission under which it is exercised, is void. No legislative act, therefore, contrary to the Constitution, can be valid.

An over-scrupulous jealousy of danger to the rights of the people, which is more commonly the fault of the head than of the heart, will be represented as mere pretense and artifice, the stale bait for popularity at the expense of the public good.
