Love, what is it?

[Cavernio]

"Or in the case of the spectrum does that suggest sometimes as you approach the end of one side you see traits exhibited on the opposite end?"
So you mean you think it might be that the spectrum is circular?

I don't think I agree with either the line or spectrum thing, although I'm not sure I fully understand the line thing. I understand the love/hate being opposite perception, but when I think about it, I certainly don't agree with it.

I think that hate and love may be close in that they are both very strong emotions, and one only experiences strong emotions when they care, or if not 'care', the focus of your hate is someone who matters. You can't hate someone you don't care about.

On a slightly different note, things like respect and admiration can make up 'love'. They can also be part of a reason to hate someone too though, like if you're in competition with them.
