The following is an excerpt from "Original Meanings - Politics and Ideas in the Making of the Constitution", a Pulitzer Prize winning hisorical account authored by Jack N. Rakove - pg 205:

"Was representation simply a device to replace the impracticable meeting of the people at large, in which case representatives should resemble their constituents as closely as possible? Or should representatives possess an independence of mind and a breadth of experience or knowledge that would provide a capacity for deliberation that ordinary citizens lacked? Did the "sympathy" desired of lawmakers require reinforcing the ties that bound them to the voters; or could it be attained, in adequate measure, through some act of imagination? The answers to these questions in turn reflected divergent definitions of the essential duties of representative institutions. Did they exist primarily to protect the people at large against arbitrary power by preventing government from acting without the expression of popular consent? Or did they not provide as well a mechanism whereby the people could authorize government to make law in the positive sense, actively adopting policies that contribute to the prosperity of the society and the happiness of its citizens?"

Again quoting from Jack N. Rakove's "Original Meanings":

"At the Convention, the framers struggled to move beyond their preoccupation with the mechanics of representation -- especially the dilemma of apportionment in both houses -- to secure the qualitative improvement in the character of deliberation and legislation they desired. Once the Constitution was published, however, Federalists were hard pressed to defend this conception of representation against more traditional norms to which Anti-Fedralists clung when they worried that a small and elite Congress would lack the sympathy and local knowledge needed to protect the people at large against the abuse of power."
