The laws of the State are not made for the good of the individual, but for the good of the whole.

Those who govern should be old, and those who are governed young.

The citizen who is not governed will not be a good governor.

In order to find the truth, you must be willing to abandon all your previous beliefs.

The best of all governments is that in which the rulers are the best and wisest, and rule according to the laws, and not according to their own arbitrary will.
