Are You Sure You Are Human?

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 (two of many) are easily quantifiable differences.

Qualitative differences are a lot more difficult to substantiate. In the absence of privileged access to the animal mind, we cannot and don't know if animals feel guilt, for instance. Do animals love? Do they have a concept of sin? What about object permanence, meaning, reasoning, self-awareness, critical thinking? Individuality? Emotions? Empathy? Is artificial intelligence (AI) an oxymoron? A machine that passes the Turing Test may well be described as "human". But is it really? And if it is not - why isn't it?
