Externalism: A subject’s belief can be justified even if the justification is not consciously available to the subject. For instance, if the belief is formed on the basis of a reliable perceptual faculty, it may be a justified belief even if the subject is not aware that the relevant faculty is reliable or even that the relevant faculty is the source of the belief.
Internalism: A subject’s beliefs are justified only if the subject has conscious access to the justification.

Aren’t these just different definitions of the word “justified”, rather than arguments about what is actually “justified”?
Quite possibly.
Yes. The question is what you mean when you say the word “justified” regarding a belief, without stating a definition.
DanArmak, Much of what goes by “philosophy” these days is isomorphic to that, in case that shocks you.
