C. Never take any theory to be trueAnti-realists are not the only group who believe that theories cannot be labeled as true. Skeptics also believe that there is never enough evidence to support the truth of a theory. The two groups do agree with each other that a theory can only be believed over another theory if one has more evidence than the other. But while anti-realists believe that observables can cause a theory to be empirically adequate, skeptics do not trust observables. They believe that what someone views is actually there to see, but they also believe that there could be a demon that is stimulating your brain to make you see and do things. Arthur Fine is a skeptic who does agree that there are “true” theories. Though Fine’s definition of “true” is that it accounts for perceptual experience, observation and other evidence. Fine does not believe that we can get “true” theories, where truth is correspondence. But he also believes that we do have “true” theories. Therefore, we must conclude that “truth” is not correspondence. Fine and other skeptics have made arguments that continually contradict each other and they have made skepticism almost completely unbelievable. Skeptics can be placed into two different categories. The first category is the skeptic who should just sit in the corner of a room and never do anything, because they believe that a demon is controlling their brain and that nothing is as it seems. The second category is the skeptic who wanders around aimlessly because they feel they cannot trust their own perception. They do not know whether to trust anything because it could be real, or it could be the demon stimulating their brain, but they do not know which is which.Theoretical realism is surely not the best way to describe the truth of theories either. For a conjunctive theory to be true, all the parts have to be true. For a theo...
