Man 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.
Bertrand RussellIn a logically perfect language, there will be one word and no more for every simple object, and everything that is not simple will be expressed by a combination of words, by a combination derived, of course, from the words for the simple things that enter in, one word for each simple component.
