Where are the Morals?

[Esquilax]

Atheism abandon the scriptures without providing any alternate model for moral code of conduct. Hence, atheists are left with no other choice than to peek into religion in pursuit of moral guidance. There is no academy in the secular world that gives awareness on morals in a scientific way.

Oh, we've got no alternative, do we? Funny, because you gave one at the top of your post:

Now the question is why rational beings (humans) should live a moral life. Short answer to that is because humans are dependent beings. A person cannot be tailor, engineer, doctor, teacher, etc., at the same time. Man finds his personal fulfilment only in relations with other people. Why be good? Because being good--living virtuously--is the only way to a fulfilled, self-actualized life.

This is it. Our evolutionary niche is sociability, and group dynamics. We have evolved to depend on one another, the richness of our lives, as you so rightly pointed out, is based upon our ability to form societies full of people who specialize. We do well because we are afforded the luxury of having people who can just teach, or just bake, or just practice medicine, because we cooperate rather than the opposite.

Hence, a rational, scientific moral system is designed around keeping the group afloat and healthy. Things that benefit thinking agents are good, things that hurt them are bad, and those things can occasionally come into conflict, which is where we must weigh one against the other. It's not easy, but it mostly works.

And incidentally, it also precludes the actions of that list of dictators you, for some reason, decided to bring in. I always like it when a theist says a bunch of stupid things and then includes the rebuttal to all of them in his own post.
