In what ways is the belief in God ACTUALLY a delusion?…
Definition of delusion -
A false belief that is resistant to reason or contrary to actual fact. (Gale Encyclopaedia of Medicine)
I think that the term delusion, when applied to religion, should be interpreted not as a mere slander term, but as an actual medical, psychological description. To me it is clear that the medical idea of a delusion and people with strong religious conviction have a lot in common.
Take some definitions for some specific kinds of delusion -
delusion of grandeur , grandiose delusion: delusional conviction of one’s own importance, power, or knowledge or that one is, or has a special relationship with, a deity or a famous person.
This delusion is obviously found in religious people. The idea of humanities cosmic importance is one which religious belief directly invents. Further than that, people who believe that God listens to prayers, looks out for our lives, and wishes to have a personal relationship with us, clearly have this delusion of grandeur. They believe that one species on a tiny planet in the vastness of space actually has significance in a large way - that the creator of the universe sent his son to be sacrificed JUST FOR US. God put all the plants and animals here JUST FOR US. God will intervene in the events of the Earth BECAUSE HE LOVES US SO MUCH.
delusion of reference a delusional conviction that ordinary events, objects, or behaviours of others have particular and unusual meanings specifically for oneself.
Many examples of this occur in religious practise. Transubstantiation - the idea that a cracker (made in a factory by humans) can turn into the body of an ancient Jew, because some man in a robe said some Latin. The idea that a rock (the black stone of Kabba) was sent down from God. The belief that rats are the incarnations of the god Karni Mata. The idea that ordinary events, like earthquakes or tsunamis or “miraculous” recoveries from the brink of death are signs from God. These types of beliefs clearly conform to the definition of a delusion of reference - objects and events that are clearly unexceptional are seen to have a greater meaning towards humanity.
And these types of beliefs are absolutely delusions, referring to the definition at the top of the post. If you reason with people - maybe show them the ‘Pale Blue Dot’ photo, or ask them to look up at the sky and think about how important they really are, the delusion will most likely persist. If you show a Creationist some fossils, or a detailed map of the genomes of apes and humans, or a virus that evolves in resistance to antibiotics - they will dodge the evidence. If you ask people why, even though they pray for things every day, the world still plays by the rules of random chance, they will not stop praying.
If you suggest that the “holy” stone that so many people consider divine is much more likely to be one of the many asteroid fragments which have fallen to Earth throughout history, rather than handed down from God, it will make little difference. When you point out that a little girl who suddenly overcame her fatal cancer is part of the small minority that this happens to, whereas all the others will die, it will not matter. It will still be attributed to god. Their beliefs are resistant to reason or contrary to actual fact.
So I think that, it is perfectly reasonable to refer to religious belief as delusional. And the implications of this are not as malicious as you may think.
One of the important features of a delusion is that it is usually reactionary. They develop because of the need to fill certain needs, which the person themselves may not feel able to fill. People want to feel they are important in the universe, and that events in the world are planned and not just random. They want to feel loved and watched over. So religion meets these needs.
And the development of a delusion can actually improve peoples lives. Having the things that people feel they lack fulfilled can have many positive benefits. This does not mean that shouldn’t be encouraged to embrace reality however. And so if movements of non-religious thinking want to be effective they need to recognize why people might need religion.
And they need to understand that merely attacking the irrational beliefs is unlikely to shake them, depending on how deep set they are. The delusion will persist unless something as good or better can be offered to meet the needs that religion does.
We must approach debates with the religious in a way that is less aggressive, and more reasonable. That puts forward why how we believe morality, happiness, love and cosmic meaning can be found in human life, without god, with empathy and compassion. Because that is the way to communicate ideas effectively, especially with people who may be gripped by delusion.
