"Habermas writes: "The ideals of freedom . . . of conscience, human rights and democracy [are] the direct legacy of the Judaic ethic of justice and the Christian ethic of love. . . . To this day there is no alternative to it."17 None of this denies that science and reason are sources of enormous and irreplaceable good for human society. The point is rather that science alone cannot serve as a guide for human society.18 This was well summarized in a speech that was written for but never delivered at the Scopes "monkey trial": "Science is a magnificent material force, but it is not a teacher of morals. It can perfect machinery, but it adds no moral restraints to protect society from the misuse of the machine. . . . Science does not [and cannot] teach brotherly love."19 Secular, scientific reason is a great good, but if taken as the sole basis for human life, it will be discovered that there are too many things we need that it is missing."
