this was the case, not in the least because, as the so-called scientific people of our day think, cunning priestly teachers of this science attributed to it such significance, but because in reality, as every one knows, both by personal experience and by reflection, there can be no science except the science of that in which the destiny and welfare of man consist.  For the objects of science are incalculable in number,—I undermine the word “incalculable” in the exact sense in which I understand it,—and without the knowledge of that in which the destiny and welfare of all men consist, there is no possibility of making a choice amid this interminable multitude of subjects; and therefore, without this knowledge, all other arts and branches of learning will become, as they have become among us, an idle and hurtful diversion.
