If an opinion contrary to your own makes you angry, that is a sign that you are subsciously aware of having no good reason for thinking as you do. [...] The most savage controversies are those about matters as to which there is no good evidence either way. Persecution is used in theology, not in arithmetic, because in arithmetic there is knowledge, but in theology there is only opinion. So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find, on examination, that your belief is going beyond what the evidence warrants.
Bertrand RussellProphets, mystics, poets, scientific discoverers are men whose lives are dominated by a vision; they are essentially solitary men . . . whose thoughts and emotions are not subject to the dominion of the herd.
Bertrand RussellPhilosophy, for Plato, is a kind of vision, the 'vision of truth'...Everyone who has done any kind of creative work has experienced, in a greater or less degree, the state of mind in which, after long labour, truth or beauty appears, or seems to appear, in a sudden glory - it may only be about some small matter, or it may be about the universe. I think that most of the best creative work, in art, in science, in literature, and in philosophy, has been a result of just such a moment.
Bertrand RussellI do not think that the real reason why people accept religion has anything to do with argumentation. They accept religion on emotional grounds.
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.
