I like to consult the dictionary. Even though I "think" I know what a word means I find it helps to see the formal definitions of words. After all, words that are simply descriptors have their limitations. They refer to aspects. But in themselves do not capture the whole. They are different from what they refer to.

So with that, the definition of real: "actually existing as a thing or occurring in fact; not imagined or supposed."

Certainly a fine line. The material scientists draw the line with weighing, measuring, and the scientific method. The logician sticks to a strict guideline of debate and argument. Rules of logic much like the mathematician.

What is a game changer is the absolute realm. There in that plane, words are absolute. In the spiritual plane, God is nondifferent from His names. He is present in sound.
