“There will be vices as long as there are men.”

Every Good Man is Free

La modération des grands hommes ne borne que leurs vices. La modération des faibles est médiocrité.

Context: p>Conventionality is not morality. Self-righteousness is not religion. To attack the first is not to assail the last. To pluck the mask from the face of the Pharisee, is not to lift an impious hand to the Crown of Thorns. These things and deeds are diametrically opposed: they are as distinct as is vice from virtue. Men too often confound them: they should not be confounded: appearance should not be mistaken for truth; narrow human doctrines, that only tend to elate and magnify a few, should not be substituted for the world-redeeming creed of Christ. There is — I repeat it — a difference; and it is a good, and not a bad action to mark broadly and clearly the line of separation between them.The world may not like to see these ideas dissevered, for it has been accustomed to blend them; finding it convenient to make external show pass for sterling worth — to let white-washed walls vouch for clean shrines. It may hate him who dares to scrutinise and expose — to rase the gilding, and show base metal under it — to penetrate the sepulchre, and reveal charnel relics: but hate as it will, it is indebted to him.</p

Context: Two objections had been raised against leaving the adjustment of the representation, from time to time, to the discretion of the Legislature. The first was, they would be unwilling to revise it at all. The second, that, by referring to wealth, they would be bound by a rule which, if willing, they would be unable to execute. The first objection distrusts their fidelity. But if their duty, their honor, and their oaths, will not bind them, let us not put into their hands our liberty, and all our other great interests; let us have no government at all. In the second place, if these ties will bind them we need not distrust the practicability of the rule. It was followed in part by the Committee in the apportionment of Representatives yesterday reported to the House. The best course that could be taken would be to leave the interests of the people to the representatives of the people.
Mr. Madison was not a little surprised to hear this implicit confidence urged by a member who, on all occasions, had inculcated so strongly the political depravity of men, and the necessity of checking one vice and interest by opposing to them another vice and interest. If the representatives of the people would be bound by the ties he had mentioned, what need was there of a Senate? What of a revisionary power? But his reasoning was not only inconsistent with his former reasoning, but with itself. At the same time that he recommended this implicit confidence to the Southern States in the Northern majority, he was still more zealous in exhorting all to a jealousy of a western majority. To reconcile the gentleman with himself, it must be imagined that he determined the human character by the points of the compass. The truth was, that all men having power ought to be distrusted, to a certain degree. The case of Pennsylvania had been mentioned, where it was admitted that those who were possessed of the power in the original settlement never admitted the new settlements to a due share of it. England was a still more striking example.

Essay on the Immortality of the Soul
Context: Heaven and Hell suppose two distinct species of men, the good and the bad; but the greatest part of mankind float betwixt vice and virtue. -- Were one to go round the world with an intention of giving a good supper to the righteous, and a sound drubbing to the wicked, he would frequently be embarrassed in his choice, and would find that the merits and the demerits of most men and women scarcely amount to the value of either.
