Full Idea
There is a class of empirical propositions, which I call 'basic propositions', which can be verified conclusively, since they refer solely to the contents of a single experience, which are incorrigible.
Clarification
'Incorrigible' means cannot be mistaken
Gist of Idea
Basic propositions refer to a single experience, are incorrigible, and conclusively verifiable

A Reaction
A classic statement of empirical foundationalism. I sort of agree that 'single experiences' are a 'given' for philosophy, but is questionable whether there is anything which could both be a single experience AND give rise to a proposition.
