Modal Argument: The Mind is Not the Brain

[Angrboda]

You don't just go making up words by slapping an "ism" on it and call it a religion or a "pseudo-religion." "Scientism" is a word made up by woo woo doctors to push a anti-science agenda. Even though it may be espoused by others, it is a nonsensical term as the definition of science does not lend itself to the creation of an "ism".
. . . .
Anyone that uses the word Scientism other than in jest is a buffoon.

scientism, n.
2. A term applied (freq. in a derogatory manner) to a belief in the omnipotence of scientific knowledge and techniques; also to the view that the methods of study appropriate to physical science can replace those used in other fields such as philosophy and, esp., human behaviour and the social sciences.

Back to Methuselah p. lxxviii,   The iconography and hagiology of Scientism are as copious as they are mostly squalid.

French Painting in 19th Cent. i. 73   It really appeared to many educated people that at last all the secrets of the universe would be discovered and all the problems of human life solved. This superstition..we may call ‘Scientism’.

tr. N. A. Berdyaev Solitude & Society i. 12   Science has not only progressively reduced the competence of philosophy, but it has also attempted to suppress it altogether and to replace it by its own claim to universality. This process is generally known as ‘scientism’.
