Benjamin Constant

The representative system is nothing but an organization by means of which a nation charges a few individuals to do what it cannot or does not wish to do herself. Poor men look after their own business; rich men hire stewards. This is the history of ancient and modern nations. The representative system is a proxy given to a certain number of men by the mass of the people who wish their interests to be defended and who nevertheless do not have the time to defend them themselves.
But, unless they are idiots, rich men who employ stewards keep a close watch on whether these stewards are doing their duty, lest they should prove negligent, corruptible, or incapable; and, in order to judge the management of these proxies, the landowners, if they are prudent, keep themselves well informed about affairs, the management of which they entrust to them. Similarly, the people who, in order to enjoy the liberty that suits them, resort to the representative system, must exercise an active and constant surveillance over their representatives, and reserve for themselves, at times that should not be separated by too lengthy intervals, the right to discard them if they betray their trust, and to revoke the powers they might have abused.
