"The people are extremely well qualified for choosing those whom they are to entrust with part of their authority. They have only to be determined by things to which they cannot be strangers, and by facts that are obvious to sense. They can tell when a person has fought many battles, and been crowned with success; they are, therefore, capable of electing a general. They can tell when a judge is assiduous in his office, gives general satisfaction, and has never been charged with bribery: this is sufficient for choosing a prætor. They are struck with the magnificence or riches of a fellow-citizen; no more is requisite for electing an edile. These are facts of which they can have better information in a public forum than a monarch in his palace. But are they capable of conducting an intricate affair, of seizing and improving the opportunity and critical moment of action? No; this surpasses their abilities.
[...]
As most citizens have sufficient ability to choose, though unqualified
to be chosen, so the people, though capable of calling others to an
account for their administration, are incapable of conducting the
administration themselves.
The public business must be carried on with a certain motion, neither
too quick nor too slow. But the motion of the people is always either too
remiss or too violent. Sometimes with a hundred thousand arms they
overturn all before them; and sometimes with a hundred thousand feet they
creep like insects."
- Montesquieu, "The Spirit of Laws"
