THREE: His [Aristotles] theory of syllogism is simply an explicit statement of the fact that all knowledge, all thought, rests on universal truths or general propositionsthat all knowledge, whether deductive or inductive, is arrived at by the aid, the indispensable aid, of general propositions. We in England have been almost charmed into the belief that reasoning is perpetually from particular to particular, and a village matron and her Lucy have been used to express the truth for us in the concrete form adapted to our weaker comprehension (Mills Logic, bk. ii. ch. 3). We shall next be told, forsooth, that oxygen and hydrogen do not enter into the composition of water, because our village matron perpetually drinks it without passing through either element, and the analysis of the chemist will be proved as great a fiction as the analysis of the logician. Aristotle has supplied the links which at once upset all such superficial389 analysis. He has shown that even in analogy or example, which apparently proceeds in this way from one particular instance to another particular instance, we are only justified in so proceeding in so far as we have transformed the particular instance into a general proposition.284It must further be noted that disbelief in a future life, as a philosophical principle, was not confined to the Epicureans. All philosophers except the Platonists and Pythagoreans were materialists; and no logical thinker who had once applied his mind to the subject could accept such an absurdity as the everlasting duration of a complex corporeal substance, whether consisting of gaseous or of fiery matter. A majority of the Stoics allowed the soul to continue its individual existence until, in common with the whole world, it should be reabsorbed into the elemental fire; but others looked forward to a more speedy extinction, without ceasing on that account to consider themselves orthodox members of the school. Of these the most remarkable instance is Marcus Aurelius. The great emperor was not blind to what seemed the enormous injustice of death, and did not quite see his way to reconciling it with the Stoic belief in a beneficent providence; but the difficulty of finding room for so many ghosts, and perhaps also the Heracleitean dogma of perpetual transformation, led him to renounce whatever hope he may at one time have cherished of entering on a new existence in some better world.359 A similar consequence was involved in the principles of the Peripatetic philosophy; and Alexander of Aphrodisias, the famous Aristotelian commentator, who flourished about 200 A.D., affirms the perishable nature of the soul on his own account, and, with perfect justice, attributes the same belief to Aristotle himself.360
