“If ever thou shalt love,
In the sweet pangs of it remember me;
For such as I am, all true lovers are,
Unstaid and skittish in all motions else
Save in the constant image of the creature
That is beloved.”

In the case of elected bodies the only way of effecting this is by the Coupled Vote. The representative unit must not be a man or a woman but a man and a woman.”
—George Bernard Shaw (1856–1950)
“While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.”
