Well, because what is real matters. The truth is better than a lie no matter how hard it is to accept.If you believe in something that is false, say for instance that homosexual acts are a sin worthy of torture, then in order for you to act morally based on that belief, you have to convince gay and bisexual people not to act on their attractions, which does a real harm in the real world. But since their is no evidence that homosexual acts are a sin, then you are doing a real harm that has consequences in this world without reducing any other harm. So why atheism? Because there is no evidence for any god or gods. If there is no evidence, why should we believe? We shouldn’t. Empiricism is the only reliable way to know what exists outside of a mental construct. And our desires have no bearing on reality except how they influence our actions.
But atheism alone is not enough. It is just one right answer. Having that answer has consequences though. If their is no god to help us, then we must help each other. No one is going to make the world a better place just by wishing, praying, or hoping. We must take action.
If you don’t have empathy, then nothing I say will make you want to make the world a better place. An atheist without empathy is useless to me. If you don’t use reason, evidence, and logic to justify your positions, then how is that different from religious faith?
So atheism alone is not enough, we also need skepticism, empathy, reason, logic, and evidence.
So you people who read my blog, why do you believe what you believe? This question is open to people of all religions and none.
