A Quote by Bertrand Arthur William Russell on conformity, mathematics, and necessity

Mathematics takes us into the region of absolute necessity, to which not only the actual word, but every possible word, must conform.

A Quote by Bertrand Arthur William Russell on mathematics

Mathematics may be defined as the subject in which we never know what we are talking about, nor whether what we are saying is true.

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.

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 chance and laws

How dare we speak of the laws of chance? Is not chance the antithesis of all law?

To fear love is to fear life, and those who fear life are already three parts dead.

A Quote by Bertrand Arthur William Russell on god, good, love, and thought

I did not know I loved you until I heard myself telling so, for one instance I thought, "Good God, what have I said?" and then I knew it was true.
