Rousseau claimed that representative governments are based on the "general will," which could somehow be different from the conscious will of the people themselves. "The general will is always right and tends to the public advantage," he wrote. "But it does not follow that the deliberations of the people are always equally correct...the people is never corrupted, but it is often deceived." - LINK
And yes, Rousseau's ideas abandon the critical notion that laws must respect the rights of man. Man cannot redefine those rights. The right which I claim is not to have my approval forced out of me with a rubber stamp in a courthouse. I will not grant that approval. If the majority of my fellow Americans also reject that approval, the government has exceeded its authority, and therefore it has lost it.
