“Truth lies within a little and certain compass, but error is immense.”

Context: The questioner says, how can the conditioned brain grasp the unlimited, which is beauty, love, and truth? What is the ground of compassion and intelligence, and can it come upon us — each one of us? Are you inviting compassion? Are you inviting intelligence? Are you inviting beauty, love, and truth? Are you trying to grasp it? I am asking you. Are you trying to grasp the quality of intelligence, compassion, the immense sense of beauty, the perfume of love and that truth which has no path to it? Is that what you are grasping — wanting to find out the ground upon which it dwells? Can the limited brain grasp this? You cannot possibly grasp it, hold it. You can do all kinds of meditation, fast, torture yourself, become terribly austere, having one suit, or one robe. All this has been done. The rich cannot come to the truth, neither the poor. Nor the people who have taken a vow of celibacy, of silence, of austerity. All that is determined by thought, put together sequentially by thought; it is all the cultivation of deliberate thought, of deliberate intent.

Es ist so gewiß als wunderbar, daß Wahrheit und Irrthum aus Einer Quelle entstehen; deßwegen man oft dem Irrthum nicht schaden darf, weil man zugleich der Wahrheit schadet.

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.
