After how long a term should members of Parliament be subject to re-election? The principles involved are here very obvious; the difficulty lies in their application. On the one hand, the member ought not to have so long a tenure of his seat as to make him forget his responsibility, take his duties easily, conduct them with a view to his own personal advantage, or neglect those free and public conferences with his constituents which, whether he agrees or differs with them, are one of the benefits of representative government. On the other hand, he should have such a term of office to look forward to as will enable him to be judged, not by a single act, but by his course of action. It is important that he should have the greatest latitude of individual opinion and discretion compatible with the popular control essential to free government; and for this purpose it is necessary that the control should be exercised, as in any case it is best exercised, after sufficient time has been given him to show all the qualities he possesses, and to prove that there is some other way than that of a mere obedient voter and advocate of their opinions, by which he can render himself, in the eyes of his constituents, a desirable and creditable representative. It is impossible to fix, by any universal rule, the boundary between these principles. Where the democratic power in the constitution is weak or over-passive, and requires stimulation; where the representative, on leaving his constituents, enters at once into a courtly or aristocratic atmosphere, whose influences all tend to deflect his course into a different direction from the popular one, to tone down any democratic feelings which he may have brought with him, and make him forget the wishes and grow cool to the interests of those who chose him............
