"Nature is either the source and the measure of our knowledge, or, if it is somehow beneath us and we are somehow its measure, then nature – including human nature – is merely some kind of cosmic playdough that we manipulate at will. The dire practical implications of such a view are evident to all men and women of good will. How is it to be refuted? Not so much by argument – for this view does not repose upon argument – as by example. It is by the patient and sober, but loving and attentive study of nature, and by the careful exposition and sharing of the results of that study, that confidence will be restored in the harmonious vision of nature as an ordered cosmos through which man the wayfarer makes his way home to his Creator." (Christopher O. Blum)
