Stupida,

While I was reading your nick at the top of your comment I was thinking how stupid is the nick. But you don't seems that stupid as your nick is suggesting. Well said, you didn't describe about the theory of love but you described some other theories to describe the love, that's ok. I like your theory of need, of course all the living beings of their needs and even non living beings are also driven by needs of nature's cycle or physical cycle. And in the simple sense love is also a kind of need. But you can't define love all the time by simple definition of love. Even you don't have needs you may have expectations from the relation or better to say from your relation. And it is not the need which will hurt you when the relations break up but it is the expectation which will hurt you during the relation break up.

And I don't agree with you that there is notthing in this world like love. May be you are good in science but it does't mean that we don't have anything in the world which is abstract. We should''t forget that those are the inorganic elements which had given birth to the organic world and with the development of the nervous system feelings and all these abstract phenomen came into the existence. It is not necessary to have all the physical measurments to prove the existence of these abstract phenomenon. You may say that whenever you get satisfaction for your need from that kind of relation it is called as love. But that doesn't matter. In fact this is the feeling and you will definitely feel you. If you are really looking for the proof of this abstract phenomenon you can do it. Just do one study fine out how the hormone secretion takes place while a person feels the satisfaction of the love. How electrolytes will work? and how the sensors of nervous system will work? There will be definitely certain differences between the biochemistry of these systems when you will have satisfaction from different abstract feelings or dissatisfaction from others.

Well I don't have to say much about your theory of duality. But it sounds good. Love with hate, good with bad,...... and so on. Do you think that a person should have dual sex so that there will be no need to be attracted towards opposite sex and there will be no hurt from love?
