4. Natural qualities or defects of mind and body cannot be imputed to any one, either for good or for bad. Who would reproach a man for being born blind, or because he became so in consequence of sickness or a blow? The same with the defects of the mind: no one is responsible for having no memory, or for not being bright. Yet as these defects may be corrected by exercise, we are more or less responsible for making no efforts to remedy them. As to the defects or deformities which result from our own fault, as, for example, the consequences of our passions, it is evident that they can justly be imputed to us. Natural qualities cannot be credited to any one. Thus we should not honor people for their physical strength, health, beauty, or even wit; and no one should boast of such advantages, or pride himself on them. However, he who by a wise and laborious life has succeeded in preserving or developing his physical strength, or who, by the effort of his will, has cultivated and perfected his mind, deserves praise; and it is thus that physical and moral advantages may become indirectly legitimate matter for moral approbation. 5. The effects of extraneous causes and events, whatever they may be, whether good or bad, can only be imputed to a man, as he could or should have produced, prevented, or directed them, and has been careful or negligent in doing so. Thus a farmer, according as he works the land entrusted to him well or badly, is made responsible for a good or bad harvest. 6. A final question is that of the responsibility of a man for other people's actions. Theoretically, no man certainly is responsible for any but his own actions. But human actions are so interlinked with each other that it is very rare that we have not some share, direct or indirect, in the conduct of others. For instance, one is responsible in a certain measure for the conduct of those under him; a father for his children, a master for his servants, and, up to a certain point, an employer for his workmen; 2, one is responsible in a measure for actions which he might have prevented, when, either through negligence or laziness, he did not do so; if you see a man about to kill himself, and make no effort to prevent it, you are not innocent of his death, unless, of course, you did not suspect what he was going to do; 3, you are responsible for other people's actions when, either by your instigations, or even by a simple approbation, you have co-operated towards them. =15. Moral sanction.=--We call the _sanction_ of a law the body of recompenses and punishments attached to the execution or violation of the law. Civil laws, in general, make more use of punishments than rewards; for punishments may appear means sufficient to have the law executed. In education, on the contrary, the commands or laws laid down by a superior, have as much need of rewards as punishments.
