Aristotle, in spite of his reputation, is full of absurdities. He says that children should be conceived in the Winter, when the wind is in the North, and that if people marry too young the children will be female. He tells us that the blood of females is blacker than that of males; that the pig is the only animal liable to measles; that an elephant suffering from insomnia should have its shoulders rubbed with salt, olive-oil, and warm water; that women have fewer teeth than men, and so on. Nevertheless, he is considered by the great majority of philosophers a paragon of wisdom.
Bertrand RussellWe are told that Sin consists in acting contrary to God's commands, but we are also told that God is omnipotent. . . . This leads to frightful results. . . . The British State considers it the duty of an Englishman to kill people who are not English whenever a collection of elderly gentlemen in Westminster tells him to do so. . . . Church and State are placable enemies of both intelligence and virtue.
Bertrand RussellThe theoretical understanding of the world, which is the aim of philosophy, is not a matter of great practical importance to animals, or to savages, or even to most civilised men.
Bertrand RussellMan is a rational animalโso at least I have been told. โฆ Aristotle, so far as I know, was the first man to proclaim explicitly that man is a rational animal. His reason for this view was โฆ that some people can do sums. โฆ It is in virtue of the intellect that man is a rational animal. The intellect is shown in various ways, but most emphatically by mastery of arithmetic. The Greek system of numerals was very bad, so that the multiplication table was quite difficult, and complicated calculations could only be made by very clever people.
