I would argue that there is no aspect of the world for which scientific discourse is "the only one the matters". Such a statement suggests a rather impoverished view of the world.
What am I for example? It depends on your perspective.
To a biologist I may be a mammal
To a barber... needing a haircut
To a psychiatrist... having a possible chemical imbalance
To Asda... an unusual customer
To a doctor... a hypochondriac
To a Hindu... out of cosmic balance
To a physicist... atoms
To the JWs... a marked individual
To my MP... a delightful constituent
What am I really? Should one discourse be prioritised to the exclusion of others? If not for a human being, then why for the earth or for anything else?
