I find this line of thought interesting. If positive soul belief outweighs the negative, and for argument sake there is no soul, what is science supposed to do? Stop seeking to understand how the central nervous system functions?
If a geocentric world view was considered more positive because centuries of culture formed around such a belief, should evidence of a heliocentric system been suppressed to avoid shattering existing cultural identity and any negative consequences?
What, in your view, is the purpose of asking fundamental questions about ourselves and the cosmos if not to get to the actual answers?
Excellent questions! I'll do my best to answer properly.
I'm one of the people the author of the piece disagrees with in that I'm unconvinced that science is equipped to answer the question, "do we have a soul?" in the first place. If a soul doesn't have physical properties, isn't purely a product of the imagination or exists in some ethereal realm that doesn't adhere to the laws and restrictions of our own world, then its existence or non-existence can't be explored by science at all. I'm personally agnostic towards that interpretation of a soul but if you ask the people who firmly believe in them if the soul has physical properties, their answer will usually be "no."
In this case, the author and I are at an impasse. While I certainly see the value in studying the central nervous system, psychology and neurochemistry, I'm unconvinced that by doing so we're studying that particular interpretation of the soul. As such, I feel that this interpretation is better examined via disciplines such as philosophy and ethics. The pragmatic approach (does soul belief cause more harm or good?) would be one way to address that subject. If the actual existence of the soul is unknowable, would we be better off believing in it or not believing in it?
That would be one distinction between studying the soul and studying the planets. Planets certainly do have physical properties and are absolutely within the purview of the sciences. I think that this is the main cause of valid accusations of scientism: a failure to accept the limitations of science.
Now the question of whether or not scientific knowledge should be suppressed if it would cause more harm than good is an interesting one to me. I'm not sure I can give a firm answer to that. As a hypothetical, if a scientist discovered a means of inflicting eternal suffering on somebody, do you feel they have a responsibility to share their findings or destroy them? If they shared their findings, I guarantee that their discovery would be put to use.
As a general rule, I think that the acquisition of knowledge is a worthy endeavour, even if that knowledge is acquired purely for its own sake. In the specific example of geocentrism you provided, I would say that the new knowledge shouldn't be suppressed. If it turned out we could definitively prove there is no such thing as an immortal soul (which again, I'm not convinced we can do) I'm much more 50/50. I would personally love to know the answer to that! However, I'm also aware that it would destroy a lot of people.
I'm sorry I can't give a firm answer to your question there but I'm also not convinced it's even wise to give a firm answer. How do you balance the acquisition of knowledge against the impact that knowledge would have? That's a question for the philosophers.
No matter your answer to that question though, I'll reiterate my main complaint about the line I quoted. The author claims
nothing would be lost. I disagree with that statement wholeheartedly and I'm curious to know your thoughts on it.
