Bertrand Russell

1872 - 1970

A Quote by Bertrand Arthur William Russell on age, discovery, facts, logic, mathematics, and principles

The fact that all Mathematics is Symbolic Logic is one of the greatest discoveries of our age; and when this fact has been established, the remainder of the principles of mathematics consists in the analysis of Symbolic Logic itself.

A Quote by Bertrand Arthur William Russell on achievement, science, and world

Almost everything that distinguishes the modern world from earlier centuries is attibutable to science, which achieved its most spectacular triumphs in the seventeenth century.

A Quote by Bertrand Arthur William Russell on belief, choice, clarity, confession, decisions, impossibility, inclusion, language, logic, problems, questions, sharing, truth, virtue, work, and writers

It seems clear that there must be some way of defining logic otherwise than in relation to a particular logical language. The fundamental characteristic of logic, obviously, is that which is indicated when we say that logical propositions are true in virtue of their form. The question of demonstrability cannot enter in, since every proposition which, in one system, is deduced from the premises, might, in another system, be itself taken as a premise. If the proposition is complicated, this is inconvenient, but it cannot be impossible. All the propositions that are demonstrable in any admissible logical system must share with the premises the property of being true in virtue of their form; and all propositions which are true in virtue of their form ought to be included in any adequate logic. Some writers, for example Carnap in his "Logical Syntax of Language," treat the whole matter as being more a matter of linguistic choice than I can believe it to be. In the above mentioned work, Carnap has two logical languages, one of which admits the multiplicative axiom and the axiom of infinity, while the other does not. I cannot myself regard such a matter as one to be decided by our arbitrary choice. It seems to me that these axioms either do, or do not, have the characteristic of formal truth which characterises logic, and that in the former event every logic must include them, while in the latter every logic must exclude them. I confess, however, that I am unable to give any clear account of what is meant by saying that a proposition is "true in virtue of its form." But this phrase, inadequate as it is, points, I think, to the problem which must be solved if an adequate definition of logic is to be found.

A Quote by Bertrand Arthur William Russell on life and possessions

It is preoccupation with possessions, more than anything else, that prevents us from living freely and nobly.

A Quote by Bertrand Arthur William Russell on facts, kindness, and universe

It can be shown that a mathematical web of some kind can be woven about any universe containing several objects. The fact that our universe lends itself to mathematical treatment is not a fact of any great philosophical significance.

A Quote by Bertrand Arthur William Russell on awareness, education, facts, future, greatness, individuality, intelligence, knowledge, life, mind, organize, past, people, power, religion, present, time, value, and wishes

If I had the power to organize higher education as I should wish it to be, I should seek to substitute for the old orthodox religions - which appeal to few among the young, and those as a rule the least intelligent and the most obscurantist - something which is perhaps hardly to be called religion, since it is merely a focusing of attention upon well-ascertained facts. I should seek to make young people vividly aware of the past, vividly realizing that the future of man will in all likelihood be immeasurably longer than his past, profoundly conscious of the minuteness of the planet upon which we live and of the fact that life on this planet is only a temporary incident; and at the same time with these facts which tend to emphasize the insignificance of the individual, I should present quite another set of facts designed to impress upon the mind of the young the greatness of which the individual is capable, and the knowledge that throughout all the depths of stellar space nothing of equal value is known to us. . . .

A Quote by Bertrand Arthur William Russell on babies, day, history, schools, and words

I found, one day in school, a boy of medium size ill-treating a smaller boy. I expostulated, but he replied: 'The bigs hit me, so I hit the babies; that's fair.' In these words he epitomized the history of the human race.
