Great knowledge sees all in one. Small knowledge breaks down into the many.
If you have insight, you use your inner eye, your inner ear, to pierce to the heart of things, and have no need of intellectual knowledge.
To be truly ignorant, be content with your own knowledge.
Study is to study what cannot be studied. Undertaking means undertaking what cannot be undertaken. Philosophizing is to philosophize about what cannot be philosophized about. Knowing that knowing is unknowable is true perfection.
Human life is limited, but knowledge is limitless. To drive the limited in pursuit of the limitless is fatal; and to presume that one really knows is fatal indeed!
For we can only know that we know nothing, and a little knowledge is a dangerous thing.
For all people strive to grasp what they do not know, while none strive to grasp what they already know; and all strive to discredit what they do not excel in, while none strive to discredit what they do excel in. This is why there is chaos.
To use what has a boundary to pursue what is limitless is dangerous; with this knowledge, if we still go after knowledge, we will run into trouble. Do not do what is good in order to gain praise. If you do what is bad be sure to avoid the punishment. Follow the Middle Course, for this is the way to keep yourself together, to sustain your life, to care for your parents and to live for many years.
