THREE:To understand Descartes aright, we must provisionally disregard the account given in his work on Method of the process by which he arrived at a new theory of the world; for, in truth, there was nothing new about it except the pro388portion in which fragments taken from older systems were selected and recombined. As we have already noticed, there is no such thing as spinning philosophies out of ones own head; and, in the case of Descartes, even the belief that he was so doing came to him from Plato; for, along with Aristotles dogmatic errors, his sound teaching with regard to the derivation of knowledge had fallen into oblivion. The initial doubt of the Discourse on Method and the Meditations is also Platonic; only it is manifested under an individual and subjective, instead of a universal and objective form. But to find the real starting-point of Descartes enquiries we must look for it in his mathematical studies. A geometrician naturally conceives the visible world under the aspect of figured extension; and if he thinks the figures away, nothing will remain but extension as the ultimate material out of which all determinate bodies are shaped. Such was the result reached by Plato in his Timaeus. He identified matter with space, viewing this as the receptacle for his eternal and self-existent Ideas, or rather the plastic medium on which their images are impressed. The simplest spatial elements are triangles; accordingly it is with these that he constructs his solid bodies. The theory of triangular elements was probably suggested by Atomism; it is, in fact, a compromise between the purely mathematical and the materialistic methods. Like all Platos fancies, this theory of matter was attacked with such convincing arguments by Aristotle that, so long as his physics remained in the ascendent, it did not find a single supporter; although, as we saw in the last chapter, Plotinus very nearly worked his way back to it from the Peripatetic definition. Even now, at the moment of Aristotles fall, it might have failed to attract attention, had not the conditions under which it first arose been almost exactly repeated. Geometrical demonstration had again become the type of all reasoning; there was again a sceptical spirit abroad, forcing men to fall back on the most elementary and universal con389ceptions; an atomistic materialism again threatened to claim at least the whole field of physical enquiry for its own. That Descartes followed the Timaeus in identifying matter with extension cannot be doubted; especially when we see that he adopts Platos analysis of body into elementary triangles; but the theory agreed so well with his intellectual predispositions that he may easily have imagined it to be a necessary deduction from his own priori ideas. Moreover, after the first two steps, he parts company with Plato, and gives himself up, so far as his rejection of a vacuum will permit, to the mechanical physics of Democritus. Much praise has recently been bestowed on his attempt to interpret all physical phenomena in terms of matter and motion, and to deduce them from the unaided operation of natural causes; but this is no more than had been done by the early Greek thinkers, from whom, we may observe, his hypothesis of an initial vortex was also derived. His cosmogony is better than theirs, only in so far as it is adapted to scientific discoveries in astronomy and physiology not made by Descartes himself; for where his conjectures go beyond these they are entirely at fault.

THREE:"Yes, sir," he answered; "you can see that I get a mounted man and a horse at reveille to-morrow. I want to hunt for my pony. I lost it when I caught that man."It was no wonder that Spain, feeling the serious effects of this state of things, should resist it; and when she did so, and exerted an unusual degree of vigilance, then the most terrible outcries were raised, and wonderful stories were circulated of Spanish cruelties to our people beyond the Atlantic. At this time the Opposition got hold of one of these, and made the House of Commons and the nation resound with it. It was, that one Captain Robert Jenkins, who had been master of a sloop trading from Jamaica, had been boarded and searched by a Coastguard, and treated in a most barbarous manner, though they could detect no proof of smuggling in his vessel. He said that the Spanish captain had cut off one of his ears, bidding him carry it to his king, and tell his Majesty that if he were present he would treat him in the same manner. This story was now seven years old, but it was not the less warmly received on that account. It excited the utmost horror, and Jenkins was ordered to appear at the bar of the House of Commons on the 16th of March, to give an account of the outrage himself; and it would appear that both he and other witnesses were examined the same day. Jenkins carried his ear about with him wrapped in cotton, to show to those to whom he related the fact, and the indignation was intense. He was asked by a member how he felt when he found himself in the hands of such barbarians, and he replied, "I recommended my soul to God, and my cause to my country." The worthy skipper had probably been crammed with this dramatic sentiment by some of his clever Parliamentary introducers; but its effect was all the same as if it had been a genuine and involuntary expression of his own mind. Researches made at the Admiralty in 1889 proved that he really had lost an ear.
