Let us compare the set „logic“ and its subsets with the set „sun“ and its subsets.

| 1) Set: Logic _ _ _ _ _ _ _|| 2) Set: Sun _ _ _ _ _ _|

| 1,1) Subset: Mathematics _|| 2,1) Subset: Hydrogen _|

| 1,2) Subset: Linguistics _ _|| 2,2) Subset: Helium _ _ |

| 1,3) Subset: Others _ _ _ _ || 2,3) Subset: Others _ _ |

Question: What happens if you take the hydrogen away from the sun?

Answer: The sun becomes bigger because of the helium burning.

If there were no mathematics, then logic would use linguistics instead of mathematics (like the logic of children, especially of little children, does).
