Secular Humanism and Humanity: What are they?

[robvalue]

Well, if you're going to say humans and not Homo sapiens then you're including a sliding scale of evolution both before and after Homo sapiens. Labels like "human" are an arbitrary way of grouping together various species. So really, being human is being part of that group. And again, whatever traits may be be involved in being human will not be unique to just humans.

I think what you are really asking is what makes Homo sapiens different from other known species. Right? That would cut out a lot of confusion here, at least the kind of confusion caused by anal little pedants like me. Otherwise you're arbitrarily including some of our ancestors which may or may not be "human" as you like to imagine the concept.
