  In the Discourse on the Origins of Inequality Rousseau imagines a multi-stage evolution of humanity from the most primitive condition to something like a modern complex society. Rousseau denies that this is a reconstruction of history as it actually was, and Frederick Neuhouser (2014) has argued that the evolutionary story is merely a philosophical device designed to separate the natural and the artificial elements of our psychology. At each step of this imagined evolution human beings change their material and psychological relations to one another and, correspondingly, their conception of themselves, or what Rousseau calls the “sentiment of their existence.” According to this narrative, humans live basically solitary lives in the original state of the human race, since they do not need one another to provide for their material needs. The human race barely subsists in this condition, chance meetings between proto-humans are the occasions for copulation and reproduction, child-care is minimal and brief in duration. If humans are naturally good at this stage of human evolution, their goodness is merely a negative and amounts to the absence of evil.  In this story, human beings are distinguished from the other creatures with which they share the primeval world only by two characteristics: freedom, and perfectibility. Freedom, in this context, is simply the ability not to be governed solely by appetite; perfectibility is the capacity to learn and thereby to find new and better means to satisfy needs. Together, these characteristics give humans the potential to achieve self-consciousness, rationality, and morality. Nevertheless, it will turn out that such characteristics are more likely to condemn them to a social world of deception, dissimulation, dependence, oppression, and domination.
