[A] large part of Barth's distaste is his sense that the ethics of liberal Protestantism could not be extricated from a certain kind of cultural confidence: '[H]ere was ... a human culture building itself up in orderly fashion in politics, economics, and science, theoretical and applied, progressing steadily along its whole front, interpreted and ennobled by art, and through its morality and religion reaching well beyond itself toward yet better days.' The ethical question, on such an account, is no longer disruptive; it has 'an almost perfectly obvious answer', so that, in effect, the moral life becomes too easy, a matter of the simple task of following Jesus.
Within this ethos, Barth also discerns a moral anthropology with which he is distinctly ill-at-ease. He unearths in the received Protestant moral culture a notion of moral subjectivity (ultimately Kantian in origin), according to which '[t]he moral personality is the author both of the conduct with which the ethical question is concerned and of the question itself. Barth's point is not simply that such an anthropology lacks serious consideration of human corruption, but something more complex. He is beginning to unearth the way in which this picture of human subjectivity as it were projects the moral self into a neutral space, from which it can survey the ethical question 'from the viewpoint of spectators'. This notion Barth reads as a kind of absolutizing of the self and its reflective consciousness, which come to assume 'the dignity of ultimateness'. And it is precisely this --- the image of moral reason as a secure centre of value, omnicompetent in its judgements --- that the ethical question interrogates.
