: one point on the original subject (sorry, i am new at this, but bear with me and i'll try to make it interesting :), communism will never work and "uptopia" can never be acceived because of one major humnan flaw: greed. in Michael Walzer essay, "Spheres of Justice, a defense of pluralism and equality", he makes and interesting point about human nature.
Right. Can you define exactly what this nebulous quality you call 'human nature' is?
See if you can give us a reasonably complete and accurate definition of what human beings will do according to any given stimulus or situation...
(...if you can, you'll put all the psychologists in the world out of business overnight...)
In my experience, it's a subjective and personal term used by people who want to defend greed, tyranny and sloth - given that human beings achieved world hegemony by rapid evolution, it seems frankly absurd that the innate 'essence' of the human being remains stuck in the Lower Palaeolithic.
We change according to our environments; human beings are capable of working together if their existence depends upon it.
(The 'human nature' idea has always reeked of predestination to me...)
