Habermas has recently startled the philosophical establishment, however, with a changed and more positive attitude toward religious faith. He now believes that secular reason alone cannot account for what he calls “the substance of the human.” He argues that science cannot provide the means by which to judge whether its technological inventions are good or bad for human beings. To do that, we must know what a good human person is, and science cannot adjudicate morality or define such a thing.10 Social sciences may be able to tell us what human life is but not what it ought to be.11
