'Yes,' he said. 'But these things (the solutions to problems in solid geometry such as the duplication of the cube) do not seem to have been discovered yet.' 'There are two reasons for this,' I said. 'Because no city holds these things in honour, they are investigated in a feeble way, since they are difficult; and the investigators need an overseer, since they will not find the solutions without one. First, it is hard to get such an overseer, and second, even if one did, as things are now those who investigate these things would not obey him, because of their arrogance. If however a whole city, which did hold these things in honour, were to oversee them communally, the investigators would be obedient, and when these problems were investigated continually and with eagerness, their solutions would become apparent.'
Plato, The Republic
Take you a glass of water
Make it against the law
See how good the water tastes
