Hi Anita and NtFs (nontheist Quakers),
I think of Bonobo chimpanzees as experiencing love (see videos here, for example - http://worlduniversity.wikia. com/wiki/Bonobo_chimpanzee). Holding Bonobo hands is one example. I also appreciate especially their peaceableness, emerging from evolutionary biology, which I think of non-theistic. What do you think?
What do you think this "love" neurophysiology or neurochemistry is, to add an aspect to the concept / idea aspect of love which you're exploring?
Here are what I think is love in some of its best senses - http://scottmacleod.com/ daltonletter.htm#BestLove.
Friendly greetings,
Scott
