But while all admit the sterling importance of strict integrity, how few practise it! Let me prevail when I entreat the young not to hazard either their reputation or peace of mind for the uncertain advantages to be derived from unfair dealing. It is _madness_, especially in one who is just beginning the world. It would be so, if by a single unfair act he could get a fortune; leaving the loss of the soul out of the question. For if a trader, for example, is once generally known to be guilty of fraud, or even of taking exorbitant profits, there is an end to his reputation. Bad as the world is, there is some respect paid to integrity, and wo be to him who forgets it. If a person habitually allows himself in a single act not sanctioned by the great and golden rule of loving others as we do ourselves, he has entered a road whose everlasting progress is downward. Fraudulent in _one_ point, he will soon be so in another--and another; and so on to the end of the chapter, if there be any end to it. At least no one who has gone a step in the downward road, can assure himself that this will not be the dreadful result. An honest bargain is that only in which the fair market price or value of a commodity is mutually allowed, so far as this is known. The market price is usually, the equitable price of a thing. It will be the object of every honest man to render, in all cases, an equivalent for what he receives. Where the market price cannot be known, each of the parties to an honest contract will endeavor to come as near it as possible; keeping in mind the rule of doing to others as they would desire others to do to them in similar circumstances. Every bargain not formed on these principles is, in its results, unjust; and if intentional, is fraudulent. There are a great many varieties of this species of fraud. 1. _Concealing the market price._ How many do this; and thus buy for less, and sell for more than a fair valuation! Why so many practise this kind of fraud, and insist at the same time that it is no fraud at all, is absolutely inconceivable, except on the supposition that they are blinded by avarice. For they perfectly know that their customers would not deal with them at any other than market prices, except from sheer ignorance; and that the advantage which they gain, is gained by misapprehension of the real value of the commodities. But can an honest man take this advantage? Would he take it of a child? Or if he did, would not persons of common sense despise him for it?
