1、1,AI & Atheism,AI: Mind without Mysticism Atheism: Life, the Universe, and Everything without Mysticism,2,Conciliatory Preface,Religious beliefs are a very significant and personal aspect of ones world view. Every individual must be free to make up their own mind about religion without undue coercio

As long as one does not contaminate ones scientific hypotheses with un-falsifiable supernatural explanations, one can be a dev

Gould, The Rocks of Ages) Science is about “The ages of rocks” Predictive theories of the material world. Religion is ab

Tell that to Copernicus, Galileo, Darwin, and other scientists that have been persecuted, despised, defamed, repressed, censored, criticized and/or ignored because their science conflicted with prevailing religious beliefs.,4,My Own Incompatible Expe

5、rience,I was raised as a devout Catholic with 8 years of parochial, religious education. I became an atheist because, as I learned more and more about science, I found scientific explanations for physical, psychological, and ethical/moral phenomena much more believable and compelling. My beliefs abo

6、ut materialism and atheism are a fairly important component of why I believe (strong) AI must be possible.,5,Science (and AI) vs. Religion,One of the original motivations for religion was to provide explanations of phenomenon that are now the province of scientific explanations. Many psychological p

7、henomena that are traditionally explained with spiritual, non-physical causes are now the province of computational (AI) explanations.,6,The History of Religion and Science,Phenomenon,Explanation,Thunder and Lightening,Origin of the Universe,Origin of Species,Origin of Humans,Origin of Life,Intellig

Bayesian formalization demonstrates that “explaining away” is a mathematically sound and correct form of inference.,8,A Bayes-Net View of Science and Religion,

A priori, belief in the existence of entities should have very low priors (Occams razor); otherwise, what prevents bel

13、sciousness, cognition, and intelligence are separate and distinct from the material world and cannot be explained as purely physical processes. Rene Descartes was a dualist who believed that the mind made contact with the physical body through the pineal gland at the back of the brain. Materialism:

14、The belief that mind, consciousness, cognition, and intelligence are physical processes that can be explained through normal scientific investigation of the material world.,12,AI Materialism Atheism,Strong AI seems to imply materialism. If purely physical, deterministic machines can be intelligent,

15、then mind is a physical phenomenon. Materialism seems to imply atheism. If the human mind is a purely physical phenomenon (Minskys “meat machine”), then there is no immaterial soul or spiritual free-will. Atheism seems to imply materialism. If there is no spiritual world, then mind must be a physica

16、l phenomenon. Materialism seems to imply strong AI. If mind is a physical process and computers can emulate any physical process (strong Church-Turing thesis), then AI must be possible.,13,Are Religion and Strong AI Compatible?,If all behavior is the result of physical causes in the material world,

17、then there is no metaphysical free will. Without dualism, how does human behavior and morality relate to a non-material God? If a truly artificially intelligent agent was created, then what would be its religious/spiritual/moral standing in relation to God? Would we be “playing God” and thereby offe

18、nd religious sensibilities by creating such a being?,14,Scientific Explanations of Religion,Religion is a ubiquitous phenomenon in human culture that itself requires explanation. Religion may arise from “spiritual” experiences that have a neurobiological basis. V.S. Ramachandran, Phantoms in the Bra

19、in, Chap. 9 “God and the Limbic System” Religion may arise from various cognitive biases of human inference and belief. P. Boyer, Religion Explained. Religion may have evolved biologically and culturally to reinforce adaptive social behavior.,15,Conclusions,AI provides scientific explanations for ph

20、enomena that were previously part of the province of religion. Belief in AI decreases belief in religion due to “explaining away,” a theoretically justified form of inference.
