Then I'll go form up with the line on the right, dear shibumi!
YOU are not the crazy person here. You are not the one trying to live in denial of reality and ultimately denial of self.
I suspect that from more propitious beginnings, kosta has become a nihilist: he has "killed God." I can only wonder why he thinks this is a good thing to do.
Oh, I forgot: with God "gone," the categories of good and evil also magically disappear. So kosta can literally do whatever he wants, without consequences.
As Nietzsche well understood, with the "death" of God, all things are not only possible, but permissible; for with God "dead," we are "beyond good and evil."
But you would sense them with your real senses (pain receptors) and not with senses you don't have a name for, would you?
Now, I used radio waves specifically because at that frequency we do not sense them nor do they have a deleterious effect on us as they pass through us, or our walls.
There is radiation we perceive as "heat" that we can sense, or light or even colors, all detected by known senses. For radiation we cannot detect with our bodies we have devices that can. The neat things is that we all sense them and detect them directly or indirectly with known sensors (natural or artificial) and no one disputes them.
Those who do can stick their hand on a red hot stove top. So, there is a universal agreement of their occurrence.
Unfortunately, we have no senses or devices that uniformly detect spirits angels and what not, except as apparently figments of our imagination, and then even those who "share" these experiences don't really agree what they are.
In the same way that the blind man senses thing around him without seeing them, we can sense the effects of what you would call the "supernatural" (which I prefer to thing of as only an "undiscovered country".)
Blind people detect things by known senses (sense we have names for) except the sense of sight. They can's 'see' light unless they can also feel the heat associated with it such as an incandescent light bulb) if they can recognize a lamp by feel. They certainly can't hear light.
None of this is an extraordinary claim and therefore can be proven by ordinary evidence demonstrable to all. But claiming that one sense the "supernatural" is extraordinary, and as such requires extraordinary evidence which amounts to more than just your word for it.
If that causes you to doubt my sanity, well, the line forms to the left.....
A guy who claims to be Napoleon said the same thing. In his world, he really is Napoleon and we are "crazy" for doubting him!
