principles, indeed, thus universally recognised, it is evident that the whole system of human things would go into confusion and ruin. Human laws may restrain or punish gross acts of violence and injustice; but they can never provide for numberless methods by which a man may injure his neighbour, or promote his own interest at the expense of others. There are, in fact, but a very few cases which can be provided for by any human institution; it is a principle within that regulates the whole moral economy. In its extent and importance, when compared with all the devices of man, it may be likened to those great principles which guide the movements of the universe, contrasted with the contrivances by which men produce particular results for their own convenience; and one might as well expect to move a planet by machinery, or propel a comet by the power of steam, as to preserve the semblance of order in the moral world, without those fundamental principles of rectitude which form a part of the original constitution of every rational being.

Farther, as each man has the consciousness of these principles in himself, he has the conviction that similar principles exist in others. Hence arises the impression, that, as he judges of their conduct by his own moral feelings, so will they judge of him by corresponding feelings in themselves. In this manner is produced that reciprocity of moral impression, by which a man feels the opinion of his fellow-men to be either a reward or a punishment; and hence also springs that great rule of relative duty, which teaches us to do to others as we would that they should do to us. This uniformity of moral feeling and affection even proves a check upon those who have subdued the influence of these feelings in themselves. Thus, a man who has thrown off all sense of justice, compassion, or benevolence, is still kept under a certain degree of control by the conviction of these impressions existing in those by whom he is surrounded. There are indeed men in the world, as has been remarked by Butler, in whom this appears to be the only restraint to which their conduct is subjected.

Upon the whole, therefore, there seems to be ground for assuming, that the articles of belief, which have been the subject of the preceding observations, are primary principles arising with an immediate feeling of conviction in our moral constitution; and that they correspond with those elements in our intellectual economy, which are commonly called First Truths,—principles which are now universally admitted to require no other evidence than the conviction which forces itself upon every sound understanding.
