Grammar is an abstract-logic mathematics system needed to
hardwire "logically" the brain of a child/teenager. Accordingly,
when grammar is properly taught to a child/teenager, some logic
neuron paths are "burned" inside his young developing brain. Further
in life, that child is capable of becoming a truly great designer,
an inventor, a creator—you name it. The idea is, his brain is
perfectly and properly geared up for logic development.
Unfortunately, the World we live in today is not only imperfect, but
is misses, alarmingly, exactly that early childhood/teenager grammar
education. As a result, children become adults, then they may
incidentally end up becoming SOMEONE IMPORTANT in our
Government, in great Corporations, or in society. However, their brains lack those fundamental
"abstract-logic neural paths" therefore they cannot understand the
"Global Picture" of the very reality they live in!
