When the guide of conduct is a moral ideal we are never suffered to escape from perfection. Constantly, indeed on all occasions, the society is called upon to seek virtue as the crow flies. It may even be said that the moral life, in this form, demands a hyperoptic moral vision and encourages intense moral emulation among those who enjoy it…. And the unhappy society, with an ear for every call, certain always about what it ought to think (though it will never for long be the same thing), in action shies and plunges like a distracted animal….

Too often the excessive pursuit of one ideal leads to the exclusion of others, perhaps all others; in our eagerness to realize justice we come to forget charity, and a passion for righteousness has made many a man hard and merciless. There is indeed no ideal the pursuit of which will not lead to disillusion; chagrin waits at the end for all who take this path. Every admirable ideal has its opposite, no less admirable. Liberty or order, justice or charity, spontaneity or deliberateness, principle or circumstance, self or others, these are the kinds of dilemma with which this form of the moral life is always confronting us, making a see double by directing our attention always to abstract extremes, none of which is wholly desirable.
