Though this progress of the sentiments be _natural_, and even necessary, 'tis certain, that it is here forwarded by the artifice of politicians, who, in order to govern men more easily, and preserve peace in human society, have endeavoured to produce an esteem for justice, and an abhorrence of injustice. This, no doubt, must have its effect; but nothing can be more evident, than that the matter has been carried too far by certain writers on morals, who seem to have employed their utmost efforts to extirpate all sense of virtue from among mankind. Any artifice of politicians may assist nature in the producing of those sentiments, which she suggests to us, and may even, on some occasions, produce alone an approbation or esteem for any particular action; but 'tis impossible it should be the sole cause of the distinction we make betwixt vice and virtue. For if nature did not aid us in this particular, 'twould be in vain for politicians to talk of _honourable_ or _dishonourable, praiseworthy_ or _blameable_. These words would be perfectly unintelligible, and would no more have any idea annexed to them, than if they were of a tongue perfectly unknown to us. The utmost politicians can perform, is to extend the natural sentiments beyond their original bounds; but still nature must furnish the materials, and give us some notion of moral distinctions. As public praise and blame increase our esteem for justice, so private education and instruction contribute to the same effect. For as parents easily observe, that a man is the more useful, both to himself and others, the greater degree of probity and honour he is endowed with, and that those principles have, greater force when custom and education assist interest and reflection: for these reasons they are induced to inculcate on their children, from their earliest infancy, the principles of probity, and teach them to regard the observance of those rules by which society is maintained, as worthy and honourable, and their violation as base and infamous. By this means the sentiments of honour may take root in their tender minds, and acquire such firmness and solidity, that they may fall little short of those principles which are the most essential to our natures, and the most deeply radicated in our internal constitution. What farther contributes to increase their solidity, is the interest of our reputation, after the opinion, _that a merit or demerit attends justice or injustice_, is once firmly established among mankind. There is nothing which touches us more nearly than our reputation, and nothing on which our reputation more depends than our conduct with relation to the property of others. For this reason, every one who has any regard to his character, or who intends to live on good terms with mankind, must fix an inviolable law to himself, never, by any temptation, to be induced to violate those principles which are essential to a man of probity and honour.
