So many philosophies, theories and changes in appreciation of each.
Yet, still we ask (essentially) the same 'historical' questions.
What marks our species as inherently different from any other? ....
I think what has changed most, certainly during the last 40 years or so, is the political influences in relation to each individuals fundamental desire, and expression in regards to the answers.
However, much of what was originally held to be true, still is.
Although how that's applied, or what it's called now, may have changed - certainly the modern descriptive definitions and understanding of the terms have.
Perhaps more interesting (?), is the lack of these questions or dismissal in any lifetime
