President Kim Il Sung was outstanding in intelligence, which cannot be compared with that of anyone in its height and depth.
Everyone, both Koreans and foreigners, admired and was surprised at the President.
Intelligence is not a natural ability, but a social product. Intelligence is inconceivable without a basis.
In general, people acquire intelligence in a study or an educational institution.
Then, what was the basis that made the President so outstanding in intelligence?
It was revolutionary practice.
The President did not get knowledge necessary for the revolution and construction much from a school teacher. He obtained some of them from books. But he acquired most of them in practice while finding himself among the people and sharing sweets and bitters with them.
People have philosophy, economics and literature!
This was the creed of the President who regarded the people as his teacher all his life and the principle he applied in his work and practice.
That was why the President knew more than others and solved complicated and knotty problems in the revolution and construction with his gifted intelligence.
