When an aspect of spiritualism is acknowledged by science, then this aspect will cease to be a feature of spiritualism and become a part of the world explained and predicted by science.
When man’s past efforts to understand spiritualism in a "scientific" way were unsuccessful, those efforts ceased to be recognized as legitimate, and became regarded as fraud or error. But that doesn’t mean that these past efforts should be expunged from history and that the desire to integrate all aspects of our existence should be viewed as a new thing. If someone were to assert that more effort has been made by humanity to integrate spirituality into reality than the effort to understand any single scientific discipline, I would not be surprised! Newton himself spent most of his life chasing mystical explanations to all sorts of things, although he is generally only remembered for his successes.
