Mostly we ponder on the as yet unexplored/unknown, or
waiting for evolution, or whatever great revelations the Brain has in store for us...if we ever get to that. But the past tense must not be discounted because it can only tell us what was; indeed this is one of the reasons I use clipmarks (and a host of other material/sources) to layout my own map of humankind. This is my push now...to know where we are headed (from what the past has taught us and what we might extrapolate from that to help us understand l) there is no such thing as EVIL, 2)science may not be the ultimate answer for all we question and I would be OK with that.
