H3 It is a definition by negation

Are we human because of unique traits and attributes not shared with either animal or machine? The definition of “human” is circular: we are human by virtue of the properties that make us human (i.e., distinct from animal and machine). It is a definition by negation: that which separates us from animal and machine is our “human-ness”. We are human because we are not animal, nor machine. But such thinking has been rendered progressively less tenable by the advent of evolutionary and neo-evolutionary theories which postulate a continuum in nature between animals and Man. Our uniqueness is partly quantitative and partly qualitative. Many animals are capable of cognitively manipulating symbols and using tools. Few are as adept at it as we are. These are easily quantifiable differences – two of many.
