Uncomfortable topic for us, and can go ignored since we tend to idealize the classical greeks. Like any phase of humanity, there are aspects we admire and aspects we revile. A slave is the possession of another person. This was a given in most ancient societies. Slaves were seen as necessary parts of the household.

Aristotle believed that barbarians and non-greeks were natural slaves. Being a greek slave changed one"s social identity in several ways: From the perspective of the master, slaves were socially dead chattel. Although they clearly continued to live and think and feel, it is hard to get a perspective from slaves because of the lack of direct evidence. Removed from their native communities and transported to an alien environment. Treated as property and as a means of production.
