Andrew Lang,
Magic and Religion
“ But surely it is above all things needful that our science should be scientific. She must not blink facts, merely because they do not fit into her scheme or hypothesis of the nature of things, or of religion. She really must give as much prominence to the evidence which contradicts as to that which supports her theory in each instance. Not only must she not shut her eyes to this evidence, but she must diligently search for it, must seek for what Bacon calls instantice contradictorim, since, if these exist, the theory which ignores them is useless. ”
