What is the essence of BEING HUMAN?

What is the essence of BEING HUMAN? What natural properties does a HUMAN BEING have? Can we find out? Do we find out through our own experience, with common sense? By feeling deeply or by allowing events into our feelings? By distinguishing between what and how we really are and  desired behavior? By looking at nature, at animals and plants? By watching a child? By watching the more natural life of primitive societies?

You tell me !!!
