Not long after leaving the teahouse, Xu Lin, with nothing much to do, went to the city library.
The collection at the city library was very rich, far beyond what Xu Lin's school had.
Here, Xu Lin could find many interesting books, or books from various fields.
On a whim, Xu Lin found a few books on logic.
Logic is unfamiliar to many people because in this country, unless you specifically study this field, you won't learn it, and there are few related majors offered in universities.
Moreover, it is a relatively profound, complex, and even abstract subject, and it is challenging to learn.
Xu Lin picked up "Logical Thinking and Sophistry," "The Pyramid Principle," and "Introduction to Logic" to read.
With a natural gift for learning, Xu Lin understood what logic was after reading them once.
But then again, what's the use of learning logic?
To argue with others?
Xu Lin wasn't so idle.
