Can you unpack why you feel emotional bias, selfishness, or personal gain are bad reasons? Is it because those conflict with your sense of ethics? Are there ways in which these things are benign or good?
I think the emotional bias one in particular confuses me. I do not know any human that lacks biases, particularly of the emotional sort. It seems it would be impossible to avoid this?
Remember, religion =/= theism and irreligion =/= atheism. I don't agree regardless, but if we could try to keep the topic to theism and atheism specifically, that would be awesome.
This was inspired by a comment made in another thread. I felt the topic was worth exploring and didn't want to derail that thread with it. It was remarked that there was a particular right reason for being an atheist. I found that idea strange, and wanted to discuss it a bit more and see if others felt there were right or wrong reasons for being an atheist or a theist. When we think about that question, it reflects something of our personal values, I think.
For example, I'm not sure I'd name any reasons as right or wrong; probably because one of my values is pluralism and I don't expect one-size-fits-all approaches or reasons for anything or anyone.
I'd define right and wrong as personal reasons why you would believe in X religion and not Y. Of course its personal preference on the same coin if there no moralities and no values true to yourself, then you can believe anything is right (and wrong). The morality and having core values lets you identify your beliefs and values in contrast with others.
For example, since you believe in pluralism, monism (if thats the right word) would be wrong for you. It doesnt work in your worldview so it cant be right for you. If it does and how you see life, you can express pluralism but once you claim values, belief, vanilla ice cream for that matter, it means something is "right" about that flavor that chocolate just doesnt do the trick. Its wording and bias behind the words moreso than the perspective of how morality shapes our decisions regardless the language.
Does being an atheist have something to do with morality?
Its an odd question, but yes (now that I understand your question). The right reason to be an an atheist is basically, how can you be amything else. Comparing it to theism, atheism (beginning to hate the word) lets me see the world from the perspective of all our beliefs come from our mind. It helps me pin things together to understand supernatural. Its using the negatives of a film to define the picture. Interesting to do. Look up neurotheology. Its a contraversal field but you may find some academics on it.
Hope that somewhat answered your question. I never heard of having a reason to "be" an atheist. We usually have reasons we act the way we do. Things we can control with our decisions we want to do whether right (what works for us) and wrong (what doesnt).
Thats like finding right or wrong reasons to be lesbian. It just is.
I know. Long winded answer. Think I got it at the end.
