Imagine a world in which the highest good, in so far as it exists, does not appear. It would not be present in the actions of those, who inhabit this somber place, nor in their minds. One might think that these people could imagine what it would be like to act ethically well and know what constitutes goodness, but this would be a mere appearance, a ghostly shadow of what is really good, which would remain outside the whole realm of fleeting and delusory phenomena. Only somebody, who had ventured to go beyond the world of appearances, would have a chance of knowing if the supreme good exists and realise what its true nature is.
