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

[Pat Mustard]

On a logarithmic scale of frequency, visible light is 2.3% of the whole electromagnetic spectrum, while on a linear scale it is 0.0035%
Our type of matter is entangled with 5 times more "dark matter" which is invisible to us.

The chances that there are living entities outside our range of perception is high.

Another "you have to disprove my claim" thread.

This time it comes in a new "you have to use my method" flavor.

"Methods?  Where we're going, we don't need....methods." ~Doc Brown.

Just because phenomenon x is outside our perception it doesn't make it non-physical. If that were the case then both you and I would be non physical because of our inability to perceive the atoms of which we are made up of.

Another science fail brought to us by Arkilogue, the man who thinks things work differently before we find out how they work than after.
