Well this thread has pretty much gone to pot. Superb. Another fantastic example of how too many egos spoil the discussion.

'Define this' and 'define that' does jack for a conversation, it's completely unhelpful and obnoxious; everyone has a different interpretation and definition of emotions, because (and this is fundamental) people feel differently.

This could have been a fairly productive thread, so here's an idea:
How about focussing simply on the topic in hand- 'The facets of love'- and whichever facet is being discussed, refer that to whatever love may mean to you.
