Theism is all about or mostly about God so if we go without defining “God” it could get difficult .
It’s not supposed to be easy, yourargument comes down to saying that the vast majority of mankind is, and alwayshas been, unscientific, illogical, and irrational, that is an extraordinaryclaim and it should be difficult to justify. I think you will be hard pressedto show that Isaac Newton was illogical, unreasonable, or unscientific, buthey, good luck with that.
I dont think I have any problems with your definition except I dont know what a “spirit” is and might challenge you on how you define god later on if it comes to that since obviously there’s much more to “god” than just a spirit or transcendent. Either way let’s get to my main arguments of why I think Theism or To Believe in God is illogical, irrational and unscientific. I know you said you want to argue all of those separately but I will lump irrational and illogical into one category for now. For me both mean almost the same- unreasonable. I will respond separately to all three after your arguments tho. Also this being more of casual debate/conversation I dont want to go all out in 4-5 long arguments and prefer this to be more like back and forth type of exchange if you dont mind.
Why do I think Theism is unscientific? If we go by your definition and think about spirituality more than what most people think of when they say god then I would still claim that science has yet to find anything spiritual or a spirit anywhere in the world.
Note: Above you said “I dont know what a“spirit” is”, and here you are referring matter of factly to “anythingspiritual or a spirit”, so I think you have conceded that one can certainlydiscuss the concept of Spirit without being able to explicitly know it’snature. Minimally, you can define spiritas what you are talking about here, and then define God as that thing thoseTheists are talking about over there.
To say that “science has yet to findanything spiritual” must certainly be explicated, what exactly do you mean bythat? The simple fact is that science hasnever found a single non-spiritual society of human beings anywhere or at anytime in history. The experience of thesacred, the common experiential reality of human beings we refer to asSpiritual, is common to all peoples in all times, and it appears to have beenreached independently among peoples and cultures that did not have contact withone another. This certainly leads one to logically conclude that a Spiritualorientation is the natural state of human beings. It is fair to say thathumanity is innately spiritual, which is to say, spirituality is the naturalorienting response to human experience.
Perhaps it would be more accurate tosay “science has yet to find anything spiritual” except for mankind, in everytime and every place they have ever looked, they have found mankind to bespiritual.
If you are saying this because of amistaken belief that science doesn’t deal with immaterial things, that is physicalism and it is simply misguided. In science there are plenty of thingsthat are not physical, but that have the power to affect things that arephysical, the study of immaterial entities are foundational to physics. Theconcept of a field in physics is not a physical or material thing, but it hasan affect on physical objects. Newtonian gravity is a field that has anobservable and measurable effect on anything with mass, but it is certainly animmaterial thing. In Relativity theory, gravity is a curvature of spacetime,still not a physical or material thing. All of the unifying theories ofphysics postulate more dimensions, most reference ten or eleven dimensions,that is to say that reality ultimately consists of at least six additionaldimensions that transcend the four-dimensional frame of reference of science.
Physicalism is not supported by science,quite the opposite, physicalism would require the causal closure of thematerial world and science has abandoned any attempt to demonstrate that. In fact, Kurt Godel provided a logicallyconsistent proof that such causal closure is impossible, even in principal.
The Theistic belief that there is atranscendent Spiritual dimension to reality is not refuted by science, andtherefore, it is not “unscientific” any more than dark matter or dark energyare unscientific because they are immaterial at best, and we do not know whattheir nature is.
Which would make the core of theism or the spirit idea itself coming from somewhere else (not science), therefore unscientific.
The things science studies do not“come from” science, they come from observation, experiment, and analysis.Consequently, the scientific evaluation of Theism is necessarily a matter ofobservation of Theism, and what we observe is these guys talking about God, butunable to define God.
If you want to say the spirit is unscientific but the belief in the spirit is scientific then I’ll hear you out.
I don’t want to say “spirit isunscientific” at all, there are different ways of knowing, science, religion,philosophy, science and religion or two different things, but that is not thesame thing as saying religion is unscientific.
Why do I think its unreasonable? I just haven’t seen one convincing evidence or argument for God or spiritually. For me it is unreasonable to believe and accept something as true in this particular case (when it is not something mundane), without any good reasons.
It is mycontention that the belief that Theism is illogical, irrational, andunscientific is a strictly unfounded and faith-based belief, it is not based onlogic, reason, or science, and consequently, rather than Theism, it is thatbelief itself that is illogical, irrational, and unscientific.
The fact is,reality is always going to be ambiguous regarding the questions being raisedhere, Theism is not logically coercive, it’s a matter of faith, which is to sayit is a choice, but for those who choose it, it does provide an intellectuallysatisfying way of making sense of the broadest possible band of humanexperience, of uniting in a single account, the rich and many layered encounterthat we have with a reality that is experienced as full of qualities, values,meanings, and purposes.
For those whodo choose it, Theism is reported to provide a sense of orientation while purporting toembrace everything, including regions of being that are presumed to existwithout their nature being known, so it can be said to be a more comprehensivepoint of view.
The theisticconclusion in no way seeks to be a rival to scientific explanation but ratherit aims to complement that explanation by setting it within a wider and moreprofound context and understanding.
Now depending on what we’re talking about exactly I can get deeper in what good reasons are for me to confirm that particular huge claim but It can be hard without mentioning any particular religion. I feel like this will be conversation that has nothing to do with the Abrahamic God so if you can get more specific about what exactly is theism for you or which one are we talking about it could be good. Thanks
I've studied comparative religions but I'm most familiar with Christianity and it's source material, a lot of Christians would disagree but I believe I can call myself a Christian for your purposes, so please feel free to proceed with that "particular religion" if you want.
