Conceptual Abstractions Of The Word "God"

"Problems with words like "God" and "Soul" are similar to the word "Number". Even though we have no ostensive definition of these three words,  we still explain them in substantial terms. Explanation of such words, however, does not prove the actual existence of these nouns, but shows their linguistic application - their grammatical-morphology."
