Internalism and Externalism
Captions available
The idea
Internalism says justification depends on factors accessible to the believer's reflection; externalism says facts outside awareness—like a process's reliability—can justify.
In practice
A trained chicken-sexer sorts chicks accurately without being able to say how. Externalists can credit knowledge; internalists balk.
Where people slip
This divide reshapes every earlier debate—what the regress demands depends on which side you take.
