Single Idea 17641

[filed under theme 1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / e. Philosophy as reason ]

Full Idea

Any new discovery as to mathematical method and principles is likely to upset a great deal of otherwise plausible philosophising, as well as to suggest a new philosophy which will be solid in proportion as its foundations in mathematics are securely laid.

Gist of Idea

Discoveries in mathematics can challenge philosophy, and offer it a new foundation

Source

Bertrand Russell (Regressive Method for Premises in Mathematics [1907], p.283)

Book Ref

Russell,Bertrand: 'Essays in Analysis', ed/tr. Lackey,Douglas [George Braziller 1973], p.283


A Reaction

This is a manifesto for modern analytic philosophy. I'm not convinced, especially if a fictionalist view of maths is plausible. What Russell wants is rigour, but there are other ways of getting that. Currently I favour artificial intelligence.


The 12 ideas from 'Regressive Method for Premises in Mathematics'

It seems absurd to prove 2+2=4, where the conclusion is more certain than premises [Russell]
Arithmetic was probably inferred from relationships between physical objects [Russell]
Which premises are ultimate varies with context [Russell]
The sources of a proof are the reasons why we believe its conclusion [Russell]
Induction is inferring premises from consequences [Russell]
Non-contradiction was learned from instances, and then found to be indubitable [Russell]
The law of gravity has many consequences beyond its grounding observations [Russell]
If one proposition is deduced from another, they are more certain together than alone [Russell]
The most obvious beliefs are not infallible, as other obvious beliefs may conflict [Russell]
Believing a whole science is more than believing each of its propositions [Russell]
Finding the axioms may be the only route to some new results [Russell]
Discoveries in mathematics can challenge philosophy, and offer it a new foundation [Russell]
