Jean Jacques Rousseau, the french philosopher, theorised that human beings are fundamentally "good" when in the "state of nature" (the state in which all the other animals are in, and humans were in before civilization and society). [his famous phrase "the noble savage"] Moreover he hypothesised that "good" people are made unhappy and corrupted by their experiences in society. He saw society as corrupt and artificial and believed that the society can only result in the continuing unhappiness of human beings.
However in a later life he reversed his thinking and contended that humans are brutish when in the natural state, as they are without laws and morality. It is only within society that humans develop what he termed the "social contract".
Is it only our societal laws that keep us from anarchy? Or do we have a fundamental desire within us to co-operate. Has this co-operation, in fact been the reason for our success as a species? I believe it has. I think it is our desire for co-operation that has lead to the creation of our laws. It is not because of those laws that we co-operate.
