For legislators make the citizens good by forming habits in them, and this is the wish of every legislator, and those who do not effect it miss their mark, and it is in this that a good constitution differs from a bad one.
Any who may wish to profit himself alone from the knowledge given him, rather than serve others through the knowledge he has gained from learning, is betraying knowledge and rendering it worthless
Slavery, you know, is nothing else than the unwilling labor of many. Therefore to get rid of slavery it is necessary that people should not wish to profit by the forced labor of others and should consider it a sin and a shame. But they go and abolish the external form of slavery and arrange so that one can no longer buy and sell slaves, and they imagine and assure themselves that slavery no longer exists, and do not see or wish to see that it does, because people still want and consider it good and right to exploit the labor of others.
