- If, as the evolutionary scientists say, what our brains tell us about morality, love, and beauty is not real – if it is merely a set of chemical reactions designed to pass on our genetic code – then so is what their brains tell them about the world. Then why should we trust them?
Morality, love, and beauty are subjective judgments. This brain of chemical reactions is able to determine the methods for objective judgments about the world. They call it the scientific method. Besides that, the emergent properties of love, beauty, etc., are not necessarily genetically programmed. We do develop our own responses that can be contrary to the best interests of the genes.
- Many people on here are proponents of strong rationalism, which is nearly impossible to defend, mostly because it can’t live up to it’s own standards. How could you empirically prove that no one should believe something without empirical proof?
I can't say that no one should believe in something, but I can say that that thing they believe in has no logical or rational support. Besides proof (which even in science is often impossible and irrelevant), we can show statistically the results of a certain pattern of behavior.
- Many say that the Bible stunts our growth as a progressive society. How can we use our time’s standard of “progressive” as the plumbline by which we decide which parts of the Bible are valid and which are not?
The bible is like an inkblot test. It contains so many contradictory statements that anyone can read into it what they want. I say chuck the whole thing out as a suitable guide to living and make up your own based on intuition, feeling, and the desires of the people.
- How could you possibly know that no religion can see the whole truth unless you yourself have the superior, comprehensive knowledge of spiritual reality you claim that none of the religions have?
If religion confined itself to amorphous spiritual matters, it would be difficult to make objective judgments about it. However, it makes claims about the physical world that can be tested.
- The last question pertains to altruistic behavior . If we see a total stranger fall into the river we jump in after him, or feel guilty for not doing so. In fact, most people will feel the obligation to do so even if he person in the water is an enemy. How could that trait have come down by a process of natural selection?
Easily. We evolved in small tribal groups. It is likely that anyone you might meet from your tribe will share a certain percentage of your genes. Therefore, it is beneficial to assist them in emergencies as well as other activities. Of course, we don't think this through like that because evolution has already shaped our brains to act in this way. Rather, people that acted this way tended to live and preserve the tendency to act this way. In fact, all social creatures behave altruistically, it's natural. Religions only codified what was already there.
