There was general agreement that the upper house or Senate should be smaller and more selective than the lower house. Its members should be gentlemen drawn from the most intelligent and virtuous among the citizenry. Experience had convinced the delegates that such an upper house was necessary to tame the excesses of the democratically elected lower house. The Virginia Plan's method of selecting the Senate was more controversial. Members concerned with preserving state power wanted state legislatures to select senators, while James Wilson of Pennsylvania proposed direct election by the people. It was not until June 7 that the delegates unanimously decided that state legislatures would choose senators.
