"The reasons for putting humanistic truth above scientific truth are not metaphysical but very practical: the discipline that helps man to self-mastery is found to have a more important bearing on his happiness than the discipline that helps him to a mastery of physical nature. If scientific discipline is not supplemented by a truly humanistic or religious discipline the result is unethical science, and unethical science is perhaps the worst monster that has yet been turned loose on the race. Man in spite of what I have termed his stupidity, his persistent evasion of the main issue, the issue of his own happiness, will awaken sooner or later to the fearful evil he has already suffered from a science that has arrogated to itself what does not properly belong to it; and then science may be as unduly depreciated as it has, for the past century or two, been unduly magnified; so that in the long run it is in the interest of science itself to keep in its proper place, which is below both humanism and religion."
