To understand why Metaphysical [/Philosophical] realism is flimsy, unrealistic and untenable read the following article from SEP. [note this is merely one short aspect of anti-realism]According to Metaphysical [/Philosophical] realism, the world is as it is independent of how humans or other inquiring agents take it to be.
The objects the world contains, together with their properties and the relations they enter into, fix the world’s nature and these objects [together with the properties they have and the relations they enter into] exist independently of our ability to discover they do.
Unless this is so, metaphysical realists argue, none of our beliefs about our world could be objectively true since true beliefs tell us how things are and beliefs are objective when true or false independently of what anyone might think.
