To know that you are simply an accidental conglomeration of chemicals at the same time that such a thing as morals even exist is oxymoronic statement and yet I hear it all the time from fellow atheists. …Be consistent. Acknowledge that the Universe is an uncaused accident, ethics is an illusion, and act accordingly. Or acknowledge the possibility of another possibility. Stop trying to have it both ways. Can you be an ethical atheist? Yes. But you won’t be a logical one.
