There are two ways to know: learning and thinking. ..... Learning is not an obstacle to thinking, but the more you learn, the farther you think; Active thinking in learning, difficult thinking in learning.

—— Wang Fuzhi

Reading makes a full man, conversation makes a quick man, and writing and taking notes make an exact man. ..... History makes people wise, poetry witty, mathematics subtle, natural history profound, ethics grave, logic rhetoric able to contend.
