Why Is Externalism Justified

We need justification for our beliefs. The idea is that where do these justifications come from. Are they based on good reasoning, evidence, personal experiences, or etc.? The broader question is whether justification is something internal or external? I believe one should be externalist about justification.

What is Internalism? Internalists argue that someone is justified about something if the thinker can recognize things from the inside. Only things that one has “first-person access” are relevant to see if a belief is reasonable or not.“Internalism treats justification as a purely internal matter: If p is justified for S, then S must be aware (or at least be immediately capable of being aware) of what makes it justified and …show more content…

This problem was initially designed against reliabilism. The problem explains that there could be identical individuals who have the same evidence for a problem, yet one’s evidence is not “truth indicative”. To illustrate, reliabalism argue that because one lives in a normal world, trusting eyes, fro example, is a reliable method, thus visual beliefs are justified. However, consider my twin is the victim of a Matrix scenario- she is a brain in a vat- and she is having the same experience as I do in a normal world due to the stimulation of her brain. When we both seem to see an object, I am justified in my belief-considering reliabalist’s method and one’s intuition- since there is actually a tree. But there isn’t any tree in the case of my twin in the matrix scenario, and her experience is systematically wrong. Is her belief justified? Since we have the same evidence and experience, if my twin’s belief is not justified then mine is neither. If my belief is justified, then so is her belief. Internalist argues that justification should not depend on whether one is deceived in an evil demon …show more content…

“S’s belief that p is justified only if the processes that produced S’s belief are reliable in normal worlds” (1986: 107). The new evil demon argument deals with the reliability requirement for justification. So Goldman tried to introduce additional sufficient arrangements for justification. Based on the new statement, the reliable process, which produces a belief, must be reliable in a “normal” world. In a normal world one’s general belief –the perceptual experience- about the actual world are true. As a result, my belief that there is a tree in front of that window is justified since it is reliable in a normal world, but my twin’s belief turn out to be unjustified.
2-Weak Justification and Strong Justification) The Normal world Reliabalism did not satisfy Goldman as a sufficient response to the new evil demon problem. He came up with this new idea of “weal” and “strong” justification. According to him: “Strong Justification: S’s belief that p is strongly justified only if the processes that produced S’s belief are reliable in the kind of environment in which S’s belief was
