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

[drfuzzy]

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?

Good.  So you have proof.  Take recordings.  Get information proving beyond a doubt that you did not falsify those recordings.  Post them.
When I have solid, reproducible data that the voices are not in your head, I'll give it another look.  Until then, no.  Personal testimony is not data.
