Secular Humanism and Humanity: What are they?

[Mudhammam]

Well, our particular genetic make-up is what makes us human to the extent that we are enabled to engage in activities that we differentiate from other species as uniquely human endeavors . . . I would say can be defined on compatible levels of abstraction, from one's close genetic relation to others...

Thanks, Nestor! Is there any essential (don't read too much into my use of the word, I simply can't think of a better one) unity to a human, or is human-ness merely a mixed composite sum of genetically human parts?

If we're gonna slice it that way I think we would probably want to extricate the human brain.
