The aim of the paper is to show, that Platoś parable of abscissa, being interpreted as an epistemological one, can be applied also to moral problems - in the long run epistémé and areté are one. In the first part of the paper the parable as such is discussed. It defines the problem of the two worlds in platonism as actually a pseudoproblem, for the chorismos between them is not an unlimited one. Both the noetic sphere (noetos topos) and the visible sphere (horatos topos) are parts of the same cosmos. In the second part it is showed, how the evil exhibits itself on the separate parts of the abscesse. In conclusion the author tries to show the problem of evil in the light of the Parable.
