Single Idea 2255

[filed under theme 13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism ]

Full Idea

Archimedes sought but one firm and immovable point in order to move the entire earth. Just so, great things are to be hoped for if I succeed in finding just one thing, however slight, that is certain and unshaken.

Gist of Idea

Only one certainty is needed for progress (like a lever's fulcrum)

Source

René Descartes (Meditations [1641], §2.24)

A Reaction

The classic foundationalist difficulty is that you may find something totally certain, but is it a fulcrum? Or is it just minimal, boring and useless?


The 16 ideas with the same theme [claim that knowledge foundations are possible]:

Maybe primary elements can be named, but not receive a rational account [Plato]
The method starts with clear intuitions, followed by a process of deduction [Descartes]
I was searching for reliable rock under the shifting sand [Descartes]
To achieve good science we must rebuild from the foundations [Descartes]
Only one certainty is needed for progress (like a lever's fulcrum) [Descartes]
Nothing should be taken as certain without foundations [Leibniz]
If anything is to be probable, then something must be certain [Lewis,CI]
Foundations need not precede other beliefs [Wittgenstein]
The 'doctrine of the given' is correct; some beliefs or statements are self-justifying [Chisholm]
Modern foundationalists say basic beliefs are fallible, and coherence is relevant [Cleve]
Externalist theories of knowledge are one species of foundationalism [Bonjour]
Foundationalism requires inferential and non-inferential justification [Dancy,J]
Foundationalists must accept not only the basic beliefs, but also rules of inference for further progress [Dancy,J]
Traditional foundationalism is radically internalist [Williams,M]
Foundationalism aims to avoid an infinite regress [Bernecker/Dretske]
Strong foundationalism needs strict inferences; weak version has induction, explanation, probability [Kvanvig]
