It is weariness to toil at the same things, and to be subject to them. Changing it finds rest. Even a potion separates into its ingredients when it is not stirred. Corpses are more fit to be thrown away than dung. Being born they wish to live and to meet death, and they leave behind children to die.
Understanding is common to all.
It is necessary for those who speak with intelligence to hold fast to the common element of all, as a city holds fast to law, and much more strongly. And though reason is common, most people live as though they had an understanding peculiar to themselves. With what they most constantly associate, with this they are at variance. It is not meet to act and speak like men asleep. They that are awake have one world in common, but of the sleeping each turns aside into a world of his own.
