Disjunction is, in truth, the primordial form of all reasoning, out of which the other forms are successively evolved; and, as such, it is common to man with the lower animals. You are taking a walk in the country with your dog. You come to a stream and jump over it. On measuring the distance with his eye, the animal is afraid to follow you. After waiting a little, he first runs up stream in search of a crossing, and, finding none, returns to look for one in the opposite direction. Failing there also, he comes back once more, and either ventures on the leap or makes his way home by some other route. Now, on considering the matter a little more382 closely, we shall find that hypothetical reasoning takes its rise from the examination of each separate alternative presented by a disjunctive premise. A plurality of courses being open to us, we consider what will ensue on the acceptance or rejection of each. The dog in our illustration thinks (after a canine fashion) that if he jumps he may fall in; if he does not, he will be left behind. Hector will not take refuge within the walls, because, if he does, Polydamas will triumph over him; nor will he offer terms of peace, because, if he does, Achilles will refuse them. Once more, categorical reasoning is developed out of hypothetical reasoning by the necessity of deducing consequences from a general rule. Hector must have argued from the known characters of Polydamas and Achilles, that in certain circumstances they would act after a certain manner. We may add, that this progress of conscious reasoning is a reproduction of the unconscious logic according to which life itself is evolved. All sorts of combinations are spontaneously produced, which, in consequence of the struggle for existence, cannot all survive. Those adapted to the conditions of life are selected, on trial, at the expense of the rest; and their adaptation or non-adaptation is determined in accordance with categorical laws. Furthermore, the framing of a disjunctive proposition necessitates the systematic distribution of possibilities under mutually exclusive heads, thus involving the logical processes of definition, division, and classification. Dialectic, as Plato understood it, consisted almost entirely in the joint performance of these operations;鈥攁 process which Aristotle regards as the immediate but very imperfect precursor of his own syllogistic method.276 You cannot, he says, prove anything by dividing, for instance, all living things into the two classes, mortal and immortal; unless, indeed, you assume the very point under discussion鈥攖o which class a particular species belongs. Yet this is how he constantly reasons himself; and even demonstrative reason383ing, as he interprets it, implies the possession of a ready-made classification. For, according to him, it consists exclusively of propositions which predicate some essential attribute of a thing鈥攊n other words, some attribute already included in the definition of the subject; and a continuous series of such definitions can only be given by a fixed classification of things. 鈥淕one? That can鈥檛 be!鈥? 鈥淚鈥檇 like to find out how the 鈥榞host鈥?gets in and out again,鈥?he reflected. The impatient Osm谩n, accompanied by the Ameer and all the holy men of the town, shortly relieved them from suspense. His scarlet abba floated over his shoulders, and the gold of his headdress sparkled in the beams of the pale orb, as he placed himself at the head of the party to receive the 鈥淪alaam Aleikum鈥?of his officers. � We have now reached a point in history where the Greek intellect seems to be struck with a partial paralysis, continuing for a century and a half. During that period, its activity鈥攚hat there is of it鈥攊s shown only in criticism and erudition. There is learning, there is research, there is acuteness, there is even good taste, but originality and eloquence are extinct. Is it a coincidence, or is it something more, that this interval of sterility should occur simultaneously with the most splendid period of Latin literature, and that the new birth of Greek culture should be followed by the decrepitude and death of the Latin muse? It is certain that in modern Europe, possessing as it does so many independent sources of vitality, the flowering-times of different countries rarely coincide; England and Spain, from the middle of the sixteenth to the middle of the seventeenth century, being the only instances that we can recall of two countries almost simultaneously reaching the highest point of their literary development. Possibly, during the great age of Latin literature, all the most aspiring Greeks found employment as tutors in Roman families; while the reading public of the West were too much absorbed by the masterpieces composed in their own language,166 or too elated with the consciousness of a new superiority, to encourage the rivalry of those from whom they had wrested not only poetical independence, but also, what till then had never been disputed with the Greeks, supreme dominion in the world of mind. It is, at any rate, significant that while Greek was the favourite language of Roman lovers in the time of Lucretius and again in the time of Juvenal, there are no allusions to its having been employed by them during the intermediate period.264 Be this as it may, from the fall of the Republic to the time of Trajan, philosophy, like poetry and eloquence鈥攐r at least all philosophy that was positive and practical鈥攂ecame domiciled in Rome, and received the stamp of the Roman character. How Stoicism was affected by the change has been pointed out in a former chapter. What we have now to study is chiefly the reaction of Rome on the Greek mind, and its bearing on the subsequent development of thought. 超碰caoporen97人人_超碰97免费人妻_人人鲁免费播放视频 � � � Of Crustaceae: near the sea-shore a Pagurus existed in astonishing numbers, and in the sweet waters a Daphnia. Many of the Ada?el are extensive owners of camels, and deal largely in slaves鈥攁 trade which yields three hundred per cent, with the least possible risk or trouble to the merchant; but when not upon the journey periodically undertaken to acquire the materials for this traffic, all lead a life of indolence and gross sensuality鈥攅ating, sleeping, and indulging in the baser passions, according to the bent of their vicious inclinations. Their delight is to be dirty and to be idle. They wear the same cloth without ablution until it fairly drops from the back; and abhorring honest labour, whether agricultural or handicraft, pass the day in drowsiness, or in the enjoyment of a quiet seat before the hamlet, where the scandal of the community is retailed. Basking in the sun, and arranging their curly locks with the point of the skewer, they here indulge in unlimited quantities of snuff, and mumble large rolls of tobacco and ashes, which are so thrust betwixt the under lip and the white teeth, as to impart the unseemly appearance of a growing wen, and if temporarily removed are invariably deposited behind the left ear. No race of men in the world stink more offensively; but whilst polluting the atmosphere with rancid tallow and putrid animal intestines, they never condescend to approach a Christian without holding their own noses!
