Contemporary atheism is a flight from a godless world. Life without any power that can secure order or some kind of ultimate justice is a frightening and for many an intolerable prospect. In the absence of such a power, human events could be finally chaotic, and no story could be told that satisfied the need for meaning. Struggling to escape this vision, atheists have looked for surrogates of the God they have cast aside. The progress of humanity has replaced belief in divine providence. But this faith in humanity makes sense only if it continues ways of thinking that have been inherited from monotheism. The idea that the human species realizes common goals throughout history is a secular avatar of a religious idea of redemption.
John Gray, Seven Types Of Atheism. (Allen Lane, 2018)
Yes, life without gods means the world is a chaotic, dangerous and meaningless place. The universe does not care. But we mortals care. And from that we derive our meaning. We find meaning in our values.
Yes, instead of looking toward a god for meaning and order, we atheists look toward reality, as it is, and toward humanity.
Caring for humanity is not a continuation of monotheism - which is nothing more than mythology.
Saying humanity realizing common goals is a secular version of religious redemption is backward. Redemption of what?
"life without gods means the world is a chaotic, dangerous and meaningless place".
The world is a chaotic, dangerous and meaningless place with or without god(s). It is what it is.
