The Godless man rejects any doctrine and any authority that attempts to go against him. He analyses any truism that he encounters trying to see if it is factual. Furthermore, he gradually makes his beliefs more and more accurate, and adapts them to the new technological and philosophical advancements of his time.
He is thus an independent thinker. Note that being Godless, means rejecting any god whatsoever. When you reject any God and any dogma, you will become “Godless”, independent and free.
