“All children are born atheists; they have no idea of god.”
Baron d’Holbach (1772), Freethoughts Opposed to Supernatural Ideas [1]

Faith in the supernatural is a desperate wager made by man at the lowest ebb of his fortunes.”

“Myself, I am a Dawkins number 10. Like Russell, I was forced to tread through a path of self-education, starting from an age 5 question about where does God live?—upward through chemical engineering studies—and further prolonged research in the field of comparative religion and mythology, in a quest for knowledge, which, to note, is embodied presently in a personal library totaling 1,247 books, of which 330 are in thermodynamics, the subject upon which the modern physical chemistry morality system is based. In plain speak, for me, the is no God—it is not even a thought in the back of my mind—there are no supernatural forces, all that exists is matter and energy governed by the laws of hard physical science; the theory of life, death, afterlife—in particular ‘life’ and the ‘origin of life’—is a defunct theory, passed on to us through religious-mythological teachings. Morality, however, does exist: and is explained within the framework of thermodynamics, the laws that govern the known universe in particular, by way of being explained by differentials of Gibbs free energy, the same energy that governs and describes the nature of the reactions that occur between the atoms of the periodic table—a morality system as outlined in 1809 [1796] by German polymath Johann von Goethe—hence I am what might be called, one step above atheism, as a ‘Goetheanist’ or a believer in Goetheanism—or humanism mixed with physicalism mixed with materialism.”
Libb Thims (2011), video (Ѻ) statement (19:10) of his Dawkins number, following Bertrand Russell's explanation of "rational morality"; an example of Goethean philosophy, Nov 1.

“I believe that the evidence, whether physical, historical, or anecdotal, for the existence of a supernatural realm is either lacking or woefully flawed, where the label “supernatural realm” encompasses both supernatural entities (from gods to human souls) and supernatural powers (from telepathy to good luck charms). In the absence of any proper evidence, the only rational conclusion is that such entities and powers do not exist but are rather the products of wishful thinking and the human imagination.”
William Jensen (2014), first part, of four, of his atheist’s creed, Oct 15 [3]
