I'm just saying, if you can't quantify it, anything goes.

Ultimately anything does indeed "go" intellectually speaking. You can draw an arbitrary line and say "it is fruitless to step over this boundary" but that is just a matter of shrinking the universe down to what you can manage. Which is fine. It does not invalidate the desire some people have to have internal intellectual experiences that do not have to be validated by you.

Philosophy is not "This is true" but rather, "What do you mean when you say, this is true".
