Dualism has the most emotionally satisfying answers to human experience of consciousness and qualia of perception, even if those answers are not actually useful in practice.
Dualism offers an alluded alternative to the "determinism vs. random" dichotomy by placing the mind outside the physical universe where nothing would seem impossible. It saves us from regarding ourselves as mindless zombies without moral responsibility, as allegedly physicalism would have it.
Dualism also greatly helps with faith in objective morality that is known to us a priori, existing in the same place as our minds, in the divine.
Dualism also plays nicely with reports of the supernatural, like family members mysteriously sensing the death of a close one in faraway lands, or people curing their cancers through prayers, or people remembering prior lifetimes and speaking in tongues they never learned.
In terms of accuracy however, physicalism is the best because it actually explains a lot of observable things, like:
- Correlation between brain activity and mind activity
- Twin studies
- Limitations of the mind and perceptions
- Split brain experiments
- Effects of brain trauma in the mind
- Effect of alcohol, drugs and medical treatment on the mind
- Differences of personality between people as hereditary trait
- Effects of genetic defects in capabilities of the mind
- Difference in absolute intelligence in the same person during childhood, adult life, old age
- Similarities between human species and animal species, without hard border down to simplest life forms
- Evolution of mind in biological evolution
- The need to sleep
- Successes of artificial intelligence
But physicalism is difficult to unify with Christian faith, early proponents risked being burned alive for suggesting it.
