evidence: There is also the problem that spending too long at the helm and having the sailors follow their every command may corrupt the mind of any navigator. The ability to get whatever they want and have their every whim seen to may well draw their focus away from the job at hand. Plato himself avoids this problem by saying that the true navigator (or the Philosopher King) is one with dialectical knowledge of the eternal Forms and the Good (and therefore wouldn’t fall victim to moral corruption), but given that the theory of Forms has been shown to have various issues in the years since the writing of the Republic (see Plato’s own Parmenides, Aristotle, or Nominalism),[2] it is difficult to accept fully the argument that he proposes.
