Earlier quoted context omitted.
Isn't love just hormones? It isn't rational reasoning at least.
A simple proof that love is not just hormones is that love can last for some time. If it was just a chemical phenomenon why does it happen repeatedly. Why can someone feel love for someone just by bringing to mind the symbol which represents that person? Why can someone feel love by seeing an illustration of someone they love?
Thinking about someone could release the hormones.
