Attachment theory

Ok, here is what i understand from attachment theory. It seems pretty straightforward and seems to explain things quite clearly. Also it is taken from a biological perspective, which is one i have respect for recently.

We all need to feel secure. So we attach ourselves to people or objects that give us a sense of security. The security is required in order to maximise our chances of survival, or to put it another way round, we define security as that which increases our chances of survival. "We" and "our" can refer to any level of replication eg individual person, family, society, species, planet, etc.

Opinion:
The thing is though, that real 'love' seems to be contrary to the acquisition of this form of security. Fear, the opposite of love, is the force which drives us to evolve. Attachment is possessive love, and is driven by fear.

We still have a need for a sense of security, even if the security does not represent a better chance of survival for us as individuals. Religion and the notion of god or oneness allows us to give ourselves up to a higher level and therefore gain a sense of security at a higher level. This improves the survival chances for 'us' at a higher level, be it community, society, etc.
