„It must not be forgotten that the rules of Courts of equity are not, like the rules of the common law, supposed to have been established from time immemorial. It is perfectly well known that they have been established from time to time — altered, improved, and refined from time to time. In many cases we know the names of the Chancellors who invented them.“
— George Jessel (jurist) British politician 1824 - 1883
