However, things — real or otherwise — that cannot be studied by the methods of science, will never be anything more than personal experience and personal testimony.
I’m not going to argue that personaly testimony is automatically false of worthless, but I will point out that it is the kind of knowledge that is used to rationalize feuds and wars.
If you cannot study, for example, the diffence between Christianity and Islam in way that is convincing to everyone, you will have endless strife.
The findings of science are limited in scope, but they are found the same by everyone who applies the methods of science, regardless of race, religion, nationality or politics.
