"Friend John, to you with so much of experience already--and you, too, dear Madam Mina, that are young--here is a lesson: do not fear ever to think. A half-thought has been buzzing often in my brain, but I fear to let him loose his wings. Here now, with more knowledge, I go back to where that half-thought come from and I find that he be no half-thought at all; that be a whole thought, though so young that he is not yet strong to use his little wings. Nay, like the "Ugly Duck" of my friend Hans Andersen, he be no duck-thought at all, but a big swan-thought that sail nobly on big wings, when the time come for him to try them. See I read here what Jonathan have written:--

"That other of his race who, in a later age, again and again, brought his forces over The Great River into Turkey Land; who, when he was beaten back, came again, and again, and again, though he had to come alone from the bloody field where his troops were being slaughtered, since he knew that he alone could ultimately triumph."

"What does this tell us? Not much? no! The Count's child-thought see nothing; therefore he speak so free. Your man-thought see nothing; my man-thought see nothing, till just now. No! But there comes another word from some one who speak without though because she, too, know not what it mean--what it _might_ mean. Just as there are elements which rest, yet when in nature's course they move on their way and they touch--then pouf! and there comes a flash of light, heaven wide, that blind and kill and destroy some; but that show up all earth below for leagues and leagues. Is it not so? Well, I shall explain. To begin, have you ever study the philosophy of crime? 'Yes' and 'No.' You, John, yes; for it is a study of insanity. You, no, Madam Mina; for crime touch you not--not but once. Still, your mind works true, and argues not _a particulari ad universale_. There is this peculiarity in criminals. It is so constant, in all countries and at all times, that even police, who know not much from philosophy, come to know it empirically, that _it is_. That is to be empiric. The criminal always work at one crime--that is the true criminal who seems predestinate to crime, and who will of none other. This criminal has not full man-brain. He is clever and cunning and resourceful; but he be not of man-stature as to brain. He be of child-brain in much. Now this criminal of ours is predestinate to crime also; he, too, have child-brain, and it is of the child to do what he have done. The little bird, the little fish, the little animal learn not by principle, but empirically; and when he learn to do, then there is to him the ground to start from to do more. '_Dos pou sto_,' said Archimedes. 'Give me a fulcrum, and I shall move the world!' To do once, is the fulcrum whereby child-brain become man-brain; and until he have the purpose to do more, he continue to do the same again every time, just as he have done before! Oh, my dear, I see that your eyes are opened, and that to you the lightning flash show all the leagues," for Mrs. Harker began to clap her hands and her eyes sparkled. He went on:--
