Right, okay, bear with me here.
Are we more driven by our love for ourselves, others, or a higher power?
My immediate answer was "others" until I thought about it some more. Why do we love others? Why do we help them out? Why do we sacrifice for others? Answer: it makes us feel good. It makes us feel good to help out somebody we love. Of course, there's nothing wrong with that, but my point is when stripped down, our motives are selfish. However unaware we are of this (probably because pleasing ourselves is so innate) our love for others is driven by our love for ourselves.
Take for example, a person who refuses himself a relationship as a form of punishment. He feels he doesn't deserve the pleasure of being in a relationship, nor have somebody love him.
The same argument applies to the "driven by love for a higher power" argument. We are benefited by our love for others.
So then, can we conclude humans are most driven by love for themselves? It makes sense, but not gonna lie, makes me sad.
