Rational and proud of it.
Thank you for a response.
Okay, so on which principles, if any, that you base your morality?
My morality is one of logic and rational reasoning. First, there's Maslow's Heirarchy of Needs: so, human beings need love, so we should love eachother. Killing one another is not loving one another, so don't do it. Hate is bad. And, to a certain extent, karma really does exist. For example, if I treat people poorly and without respect they're probably not going to treat me respectfully or with compassion, and if I feel negatively things will seem darker or less cheerful and bright. Or if I act negatively, there's a chance that my actions will have negative effects which could come back to me in some way. There's the Golden Rule, Kant's Moral Imperative, and, if you've never read anything about it you might get the wrong idea but, Secular Humanism. One can extrapolate morality from the following:
3 Basic Tenets of Human Secularism:
1. Humans have value and can solve human problems.
2. Science, free speech, democracy, rational thought, and freedom in the arts go together.
3. There is nothing supernatural.
And don't forget the Social Contract. As an atheist and an agnostic, life is given no universal meaning and so I must make meaning for it myself: which means that if I act in ways which do not conform to my morality I diminish or even nullify the meaning of my own existence - instead of fearing eternal damnation (which to me is not nearly as much incentive to act morally as immediate meaninglessness and this is not an external motivator but an internal one which is inherently more powerful).
That's a REALLY simplified and brief answer for such a broad subject.
