Fault-finding and blame arises, either solely or most naturally, in Friendship of which utility is the motive: for they who are friends by reason of goodness, are eager to do kindnesses to one another because this is a natural result of goodness and Friendship; and when men are vying with each other for this End there can be no fault-finding nor contention: since no one is annoyed at one who entertains for him the sentiment of Friendship and does kindnesses to him, but if of a refined mind he requites him with kind actions. And suppose that one of the two exceeds the other, yet as he is attaining his object he will not find fault with his friend, for good is the object of each party. Neither can there well be quarrels between men who are friends for pleasure’s sake: because supposing them to delight in living together then both attain their desire; or if not a man would be put in a ridiculous light who should find fault with another for not pleasing him, since it is in his power to forbear intercourse with him. But the Friendship because of advantage is very liable to fault-finding; because, as the parties use one another with a view to advantage, the requirements are continually enlarging, and they think they have less than of right belongs to them, and find fault because though justly entitled they do not get as much as they want: while they who do the kindnesses, can never come up to the requirements of those to whom they are being done. It seems also, that as the Just is of two kinds, the unwritten and the legal, so Friendship because of advantage is of two kinds, what may be called the Moral, and the Legal: and the most fruitful source of complaints is that parties contract obligations and discharge them not in the same line of Friendship. The Legal is upon specified conditions, either purely tradesmanlike from hand to hand or somewhat more gentlemanly as regards time but still by agreement a _quid pro quo_. In this Legal kind the obligation is clear and admits of no dispute, the friendly element is the delay in requiring its discharge: and for this reason in some countries no actions can be maintained at Law for the recovery of such debts, it being held that they who have dealt on the footing of credit must be content to abide the issue. That which may be termed the Moral kind is not upon specified conditions, but a man gives as to his friend and so on: but still he expects to receive an equivalent, or even more, as though he had not given but lent: he also will find fault, because he does not get the obligation discharged in the same way as it was contracted.
