Nothing nonexistent is detectible empirically. Nothing necessarily (versus contingently) undetectable can be said to exist. Have you ever made a list of the qualities that distinguish the existent from the nonexistent? Things that exist occupy space and time and interact with other things that exist. Contrast a wolf and a werewolf. There are places I can go and see a wolf. That gives the wolf a place in time and space, and specifies an interaction: experiencing and interpreting the light reflected from it to my eyes, and maybe experience it further if it's hungry and has access to me. You can't do any of that with a werewolf. Or the supernatural. This, we group the supernatural with werewolves, since they have so much in common, and not with wolves, which for the reasons given are to be classed among the real.
Get a little bit of education in science rather than passing nonsensical comments. A tad in the basics of philosophy of science would do. Five minutes at least.
An impotent and disappointing reply, but not surprising. Do you really believe that you have a superior understanding of science or philosophy? Then demonstrate it. You wilted at the thought of a discussion of ideas with me. An active and inquisitive mind might have been intrigued by a philosophical discussion of the difference between "being and nothingness." Somebody who actually had the knowledge of philosophy you dismissively imply you possess ought to have been as enthusiastic about sharing some of that expertise as I was when I made my comment on the topic, whereas somebody who was insecure in his knowledge might shy away.
As always, the last plausible, unrebutted statement ends and resolves debate. Why? Because the purpose of dialectic is to resolve differences of opinion and determine which if either of two mutually exclusive opinions is correct. You gave an opinion and I rebutted it. You imply that the supernatural is real and exists. I explain why it should be classed with the nonexistent. We can't both be right, but one us can be, and if somebody is correct, his claim can't be successfully rebutted, and stands as the last plausible, unrebutted statement.
So did you want to try to defend your position from my rebuttal, or are you unable?
How do you know that your senses are reliable? If you say that your senses are reliable because your senses tell you, then that would be circular reasoning. Don’t take me seriously, I am just making random “Matrix-Like” philosophy. It is just that by claiming that knowledge comes from your senses you are making the untestable assumption that your senses are reliable.
All I require of my senses and mind is that they allow me some measure of control of how my life experience proceeds. The evolutionary value of belief resides in its ability to inform decisions and drive actions, which lead to events in the external world, which in turn lead to objective consequences evident to the senses. Take away any of these elements and "truth" immediately loses all relevance. The ultimate measure of a true or false proposition lies in its capacity to produce expected results.
If an idea is true or correct, it can be used in the real world to generate predictable consequences, and different ones if that idea turned out to be false. In other words, the ultimate measure of a true proposition is its capacity to successfully inform decisions under the expectation of desirable consequences. By this method, one accumulates demonstrably correct ideas - one's fund of knowledge - and generates a mental map of reality that corresponds with the features of reality the way a literal map corresponds to actual geographic features one might encounter. If your map is wrong, you won't reach your desired location, and the only way to have a correct map is to survey the landscape it intends to map.
If this works, it really doesn't matter what else is true about reality. Perhaps we are in a matrix-like world, and that there is no substance underlying our perceptions, no real world "out there" corresponding to the model we use to navigate reality. Maybe my finger doesn't exist. Maybe that flame there is an illusion of some sort. My senses and mind cannot answer that for me, and may be very mistaken about the nature of reality.
But even if I knew for a fact that it was all a dream of some sort, what choice do I have but to continue living it? If the illusion of willing an unreal finger into an unreal flame reliably produces the pain of fire, nothing changes. My senses and mind remain a reliable predictor of future outcomes even if my metaphysics is incorrect. As long as that continues to be the case, I will successfully continue to rely on those senses. It is the results of trusting the evidence of the senses that determine whether this is a reliable method.
