Have you forgotten our old principle of the division of labour, or of every man doing his own business, concerning which we spoke at the foundation of the State--what but this was justice?
Is there any other virtue remaining which can compete with wisdom and temperance and courage in the scale of political virtue?
For 'every one having his own' is the great object of government; and the great object of trade is that every man should do his own business.

Not that there is much harm in a carpenter trying to be a cobbler, or a cobbler transforming himself into a carpenter; but great evil may arise from the cobbler leaving his last and turning into a guardian or legislator, or when a single individual is trainer, warrior, legislator, all in one.

And this evil is injustice, or every man doing another's business.

I do not say that as yet we are in a condition to arrive at a final conclusion.

For the definition which we believe to hold good in states has still to be tested by the individual.
