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

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?

What you believe isn't relevant. What you can demonstrate to be probably true is all that matters. Voices in your head can easily be explained in much more plausible ways. I'm actually concerned about mental illness, when people say they hear real voices. It's quite possible you just think you're hearing voices, but really you're reworking your thoughts into speech in your head.

However, most sceptics don't make statements such as "X doesn't exist". They would say "There is no reason to yet believe X exists". So you're misrepresenting the position. Until such time as there is positive evidence for something, it can be safely ignored. Anecdotes, such as yours, are not reliable evidence.
