Natural science enables us, it is supposed, first to know what science properly is. Other sciences—which purport to exhibit a radically divergent type—are either of doubtful authenticity and highly disputable value, or else humbug, which has long since become transparent. If now the humanists are to be compelled to practise science, they will have perforce, nolentes volentes, to take the natural sciences for their model and adopt their methods. Extra ecclesiam nulla salus. Under no circumstances is recognition extended to a distinctive humanistic type of science side by side with the type of natural science. The distinctions between scientific forms and methods of procedure, which are forthcoming, accordingly all turn out to constitute merely variations within natural science itself.
