But directly afterward, on the other side, came Montaigne, whose sceptical acuteness could arrive at negatives without any apparatus of method. A certain keen narrowness of nature will secure a man from many absurd beliefs which the larger soul, vibrating to more manifold influences, would have a long struggle to part with. And so we find the charming, chatty Montaigne—in one of the brightest of his essays, “Des Boiteux,” where he declares that, from his own observation of witches and sorcerers, he should have recommended them to be treated with curative hellebore—stating in his own way a pregnant doctrine, since taught more gravely. It seems to him much less of a prodigy that men should lie, or that their imaginations should deceive them, than that a human body should be carried through the air on a broomstick, or up a chimney by some unknown spirit. He thinks it a sad business to persuade oneself that the test of truth lies in the multitude of believers—“en une prosse où les fols surpassent de tant les sages en nombre.” Ordinarily, he has observed, when men have something stated to them as a fact, they are more ready to explain it than to inquire whether it is real: “ils passent pardessus les propositions, mais ils examinent les conséquences; _ils laissent les choses_, _et courent aux causes_.” There is a sort of strong and generous ignorance which is as honorable and courageous as science—“ignorance pour laquelle concevoir il n’y a pas moins de science qu’à concevoir la science.” And _à propos_ of the immense traditional evidence which weighed with such men as Bodin, he says—“As for the proofs and arguments founded on experience and facts, I do not pretend to unravel these. What end of a thread is there to lay hold of? I often cut them as Alexander did his knot. _Après tout_, _c’est mettre ses conjectures â bien haut prix_, _que d’en faire cuire un homme tout dif_.” Writing like this, when it finds eager readers, is a sign that the weather is changing; yet much later, namely, after 1665, when the Royal Society had been founded, our own Glanvil, the author of the “Scepsis Scientifica,” a work that was a remarkable advance toward the true definition of the limits of inquiry, and that won him his election as fellow of the society, published an energetic vindication of the belief in witchcraft, of which Mr. Lecky gives the following sketch:
