Understanding begins with logic

- SOCRATES: So now, I replied, watch the process whereby the prisoners are set free from their chains and, along with that, cured of their lack of insight, and likewise consider what kind of lack of insight must be if the following were to happen to those who were chained. Whenever any of them was unchained and was forced to stand up suddenly, to turn around, to walk, and to look up toward the light, in each case the person would be able to do this only with pain and because of the flickering brightness would be unable to look at those things whose shadows he previously saw... And if someone were [then] to show him any of the things that were passing by and forced him to answer the question about what it was, don't you think that he would be a wit's end and in addition would consider that what he previously saw [with is own eyes] was more unhidden than what was now being shown [to him by someone else].
— Yes, absolutely.
