Future rulers must be trained to excel in asking and answering questions; dialectic is the coping-stone set over all sciences—the highest reach of knowledge.

By Plato, from The Republic

Key Arguments

  • Rejects mindless rulers: 'you would not allow the future rulers to be like posts... having no reason in them'.
  • Legislative requirement: 'you will make a law that they shall have such an education as will enable them to attain the greatest skill in asking and answering questions'.
  • Rank of dialectic: 'the coping-stone of the sciences, and is set over them; no other science can be placed higher—the nature of knowledge can no further go?'
