PHIL 221 Lecture Notes - Lecture 4: Circular Motion, Heliocentrism
Document Summary
X is underderemined by y when y is insuf cient to decide x. You spent 10 dollars on apples and oranges. The exact number of apples and oranges i bought is underdetermined by the information i have. Therefore my belief is constrained by not uniquely constrained by the information i have. You have at least multiple alternatives in how many oranges and apples i bought. Duhem is advancing the idea that theoretical claims are underdetermined by evidences. Th evidence presented is never enough to make a theory true or false as there will always be multiple outcomes. There will also never be enough evidence to make the theory fully correct, you can only reject theories depending on its modi cation. Both of the wave and particle theory could be compatible with foucault"s results if there was modi cation of certain elements in either theory.
