A few people have asked me recently what I think the purpose or meaning of life is as an atheist. They would be correct to say that atheism itself cannot inform me about the meaning or purpose of life, since atheism is defined as merely being a lack of belief in any gods (it should be pointed out that mere theism -- that is, the mere belief in a god or gods -- cannot inform someone about the meaning or purpose of life either. Only particular theistic doctrines or philosophies can inform on that level.) Nonetheless, I do have an answer that I believe in with regards to this question, and I would happily share it.
