IIRC, it was Wilson who looked around the room and observed that it was populated by a majority of lawyers. He then warned that it they weren't careful that what the people would get would be a government of the same.
Hamilton pooh-poohed Wilson's concern in the Federalist with his usual blustering snow-job. I wish I had the references because the contrast is yet another instance that shows Hamilton for whom he really represented.
In early June at the Constitutional Convention, John Dickinson warned that if all power were “drawn from the people at large, the consequence would be that the national Government would move in the same direction as the State governments now do and would run into all the same mischiefs.” State participation in the new government largely solved the "great desideratum;" how to base a government on popular will, yet protect minority rights from majoritarian abuse.
Had Hamilton not written most of The Federalist, the world's greatest gift to political science and freedom, our Constitution, would have been stillborn.
