[...] you cannot aim at 'doing what is right', because you will never know whether you have hit the mark. Long after you are dead, better informed and more sophisticated people may judge your action to have been a tragic mistake, just as they may judge your scientific beliefs as intelligible only by reference to an obsolete paradigm. But you can aim at ever more sensitivity to pain, and ever greater satisfaction of ever more various needs. Pragmatists think that the idea of something nonhuman luring us human beings on should be replaced with the idea of getting more and more human beings into our community - of taking the needs and interests and views of more and more diverse human beings into account. Justificatory ability is its own reward. There is no need to worry about whether we will also be rewarded with a sort of immaterial medal labelled 'Truth' or 'Moral Goodness' .
