What philosophical evidence is there against believing in non-physical entities?

[Pat Mustard]

Materialism is dead nowadays as a serious philosophical theory. I think the Kantian realization that the world is dependent on our senses causes us to to doubt that we can contain the world in language or our thoughts. Science has not disproved the existence of other dimensions.


Why would people be unwilling to acknowledge the possibility that spiritual entities exist? I talk to them every day and they talk back to me, using English words and language. I am sure this is real and most societies have had some sort of concept of this. Why would people be unwilling to acknowledge there could be other life besides human life?

There is no philosophical evidence ether for or against non-physical beings, mainly because philosophy doesn't deal in evidence. The best reason to not believe in a non-physical entity is that we have not devised a system where one could exist and interact with the real world (even energy based beings, the closest to non-physical beings yet hypothesised, have a physical presence).
