Sriram,
No!
Perception is like a fundamental program. That is the means by which information will be processed. Depending on ones perception, information will be processed accordingly. For example, if a person beliefs in a particular deity, that is the way the mind will work regardless of the evidence. Some people believe that the devil plants fossils. That is programming or perception regardless of the information.
Similarly, some people have a materialistic perception...a mindset. It is a form of programming that will not change whatever the evidence. All evidence will be seen only from that angle...and will be justified or rationalized accordingly.
Dear God but you struggle. I can line up ten people before breakfast, each of whom “perceive” something different to be true – the Christian god for the first one, Allah for the second, Poseidon for the third, Colin the Laird of Leprechaunland for the fourth etc.
A “materialistic mindset” as you put it isn’t though a perception of anything –
it’s a method to investigate the validity or otherwise of the perceptions that people do have, but that’s all.
Materialism doesn’t even claim to falsify the perceptions it can’t address. Rather it just says, “perceptions A, B and C are justified by this method, but perceptions D, E and F are not”. That’s not to say that D is not true (leprechauns say), but it is to say that this method provides no reason to think that it is. And your problem when you perceive D, E or F to be true nonetheless is that you offer no other means to test the claim. The various claims of non-naturalistic fact you make are therefore precisely as (in)valid as any others that fall outwith the purview of materialism.
This isn’t hard to grasp if only you’d try. Really it isn’t.
