The rationale for altruism (irrationality of egoism) Hi Tom,
1. Coded by genetics to perform a variety of actions with the physical body. This was a general statement in that regard. The "phenotype" in other words. The behavior can be self-directed or other-directed in this capacity. Gratuitous, in that context, means without having to give-back. You don't have to give back your body or life (unless you want). If you fill a glass of water because you are thirsty, the cup is not going to reject the liquid, it's going to SERVE that liquid (does that help?). It is the hardest part to explain in abstract terms, for me.
2. All self-serving actions involve the guarding/re-establishing the sense of self. Hegel's master-slave dialectic illustrates the consequences of such a mindset. It's basically ego against ego (as opposed to ego for ego...)
3. My name is Paul and if you meet me, you'll see my form, which is to say my body. If I help you, then I go from an identifiable form to a functioning entity that extends its usefulness beyond itself to you (which is your real ego self, I believe).
Did this help, or is there something that doesn't seem right?
Thank you for response,
Paul
