What purpose is there for love? If it were merely in order to ensure procreation we would not see the social dramas which can tear apart groups and structures. Love exists in a purely non-sexual form; that of a mother and child. Love and sex are not linked in reality but thrust together in a media bombardment. If we were not shown love portrayed by Hollywood, would we sacrifice so much of our time in the pursuit of it?
Love can be explained as a rush of endorphins used to ensure protection of another being that is not ourselves. Chemicals place attachment on another being over ourselves, but what for? How does this explain the love for a husband over a wife after a child is born, or the love of a father after his daughter has grown? What use is it? It can be seen as unnecessary attachment and often is by those wishing to rid themselves of responsibility of another. This could be it; are we wishing for responsibility for another?
If this is true, it also does not make sense. Why would we as a species spend so much of our time hoping for increased responsibility? The answer to that is this: We are not looking for responsibility but looking for someone to take the responsibility of ourselves away from the individual. Most of the time, we wish not to love but be loved. This explains the sting of rejection and the hurt one feels when we are alone. It explains religion and hierarchy. We all just want to not be responsible for ourselves. Life is hard, we want someone else to live it for us.
Unconditional love, as that for a child, is different. We love without the thought of being loved in return and often suffer the years of abuse and emotional neglect because we shoulder the responsibility for them. They ensure our species survival and our personal genes. They will live for us when we are gone. This is a good reason to love.
Being lonely is an obvious part of life. When we get excited over potential romantic contact, it is not at the possibility of love but at the opportunity to not suffer personal responsibility. We forget that we are not unselfish creature. We are scared and alone. vulnerable children. When we grow our responsibilities grow to the point where not even a mother can shoulder them. So we look for a mate. However, we cannot rely on another shouldering our pain for us because they have to shoulder their own pain too. If you want to love, then care for another without fear of rejection. Shoulder their pain and carry their weight but don’t expect the same in return. If you love someone you don’t want to give them your pain too.
