The discussion with Beth ends with
post #1308 on page 33 in this thread. You'll do best to work back from there rather than try to go forward from wherever it starts. The points got clearer in the end and were repeated a lot in the middle. Beth may have had more to say but she's temporarily limited in typing due to a finger injury.
I don’t want to step on Beth’s toes, or get embroiled in the other thread right now, so I’ll try to keep this short.
In the case of the conclusion a thing is red because it looks red, the color of the thing is still the evidence.
Not quite, the
experience of the colour of the thing is the evidence. That the thing is a certain colour is the conclusion.
Evidence is a physical thing. It exists.
Are we back to “exists” = “physical” now?
One can dissect the neuro sensory system in a person.
Indeed, and one will not find “red” there because it is a transitory pattern of firings of neurons, not the neurons themselves. The experience of red, and the experience of god, are not physical. They are not independent of the physical activity of the neurons, but they are not in themselves physical entities. You can map them, such as with Alric’s EEG, but “the map isn’t the territory”.
In the case of the red evidence, we have the red thing.
Here is your error repeated. The red thing is not evidence of red. The experience of “red’ is evidence that the thing is perceived as “red”. What the thing is, what shade of red it is, may be up for debate, but the experience of percieving the thing as "red" is evidence that there is a thing and that a quality is possess is reflecting light in the wavelengths humans have learned to call "red". Nothing more. It might not be conclusive, incontrovertable evidence, but it is evidence.
Contrariwise, Beth’s assertion that the experience of god is evidence of god is misleading and incorrect as well. What is experienced when most people say they “felt god” or “communed with god” is an emotional reaction to certain stimuli, such as attending church. This experience is evidence that the experiencer had an emotional reaction to something. Whether that “something” can be called “god” or not is up for debate and needs more evidence, but the experience is evidence that “something” does exist and a quality it possesses is engendering the experienced emotional response. It might not be conclusive, incontrovertable evidence, but it is evidence.
Therefore, it seems to me that both of you mixed up "evidences" and "conclusions". I don't think I am doing that.
ETA: Plumjam and I had a very similar discussion just a couple days ago, in the midst of a lot of other things. Starts
here, if you are interested.
