There are many situations in life, and particularly in the commercial world, where a man cannot by any diligence inform himself of the degree of credit which ought to be given to the persons with whom he deals; in which cases he must apply to those whose sources of intelligence enable them to give that information. The law of prudence leads him to apply to them, and the law of morality ought to induce them to give the information required.
