In the Washington Post on Monday

[socrtwo]

My apologies to all for insulting insinuations about Darwin's name.

Monday morning's Washington Post had a story about how they have found
that when someone engages in a service act (helping others) that this
lights up a similar part of the primitive brain that lights up during
when a person experiences sex or eats:

Also it mentioned an experiment that showed that if you have two rats
where one rat gets shocked every time the other rat pushes a lever for
food (or something like that), the rat that doesn't get shocked but
knows about the other one will stop eating. Presumably the non-shocked
rat knows about the shocked one by sight, sound, smell, and/or hearing
his companion.

This was front page news. They went on to talk about how there seems
to be a competition in the mind between selfish and empathic parts of
the brain, but these part of the brain were at least both in part
based in the most primitive parts of the human gray matter...
