The Problem of InductionThe Problem of Induction

Soazig Le Bihan - University of Montana

Our expectations about the future and the idea of uniformity of nature are not well-founded. Unless… our ideas of causes and effects, of necessary connections were well grounded?

At stake:Justification of our expectations of the future (based on our sole experience of the past and present) ?

The Problem:- No a priori justification- No a posteriori justification – circular argument

No experience of connection (even less necessary) – words without meaning?

Copy PrincipleMeaning = simple impression from which the idea is a copyCause, or necessary connection: from which impression do these idea come from?

The Problem:- Not from sensation: no sensory experience of connection – only conjunction- Not from reflection – no reflective experience of connection – neither in its interaction with the body, nor in its interaction with the ideas

Burning worthless books?
