When I came first to the University I was as nearly without a moral conscience as a boy could be. Some faint distaste for cruelty and for meanness about money was my utmost reach—of chastity, truthfulness, and self-sacrifice I thought as a baboon thinks of classical music. By the mercy of God I fell among a set of young men (none of them, by the way, Christians) who were sufficiently close to me in intellect and imagination to secure immediate intimacy, but who knew, and tried to obey, the moral law. Thus their judgement of good and evil was very different from mine. Now what happens in such a case is not in the least like being asked to treat as ‘white’ what was hitherto called black. The new moral judgements never enter the mind as mere reversals (though they do reverse them) of previous judgements but ‘as lords that are certainly expected’. You can have no doubt in which direction you are moving: they are more like good than the little shreds of good you already had, but are, in a sense, continuous with them. … It is in the light of such experiences that we must consider the goodness of God. Beyond all doubt, His idea of ‘goodness’ differs from ours; but you need have no fear that, as you approach it, you will be asked simply to reverse your moral standards. When the relevant difference between the Divine ethics and your own appears to you, you will not, in fact, be in any doubt that the change demanded of you is in the direction you already call ‘better’. The Divine ‘goodness’ differs from ours, but it is not sheerly different: it differs from ours not as white from black but as a perfect circle from a child’s first attempt to draw a wheel. But when the child has learned to draw, it will know that the circle it then makes is what it was trying to make from the very beginning.
