Another question is, whether a friendship should or should not be broken off when the friends do not remain the same. It may be said that where the motive of the friendship is utility or pleasure, it is not unnatural that it should be broken off when our friends no longer possess the attribute of being useful or agreeable. It was those attributes that we loved, and when they have failed it is reasonable that love should cease. But a man might well complain, if, though we really liked him for the profit or pleasure he afforded, we had pretended to love him for his character. As was said at the outset,1 differences between friends most frequently arise when the nature of their friendship is not what they think it is.
