To know that you do not know is the best.To think you know when you do not is a disease.Recognizing this disease as a disease is to be free of it.

Тhe gentle overcomes the rigid.The slow overcomes the fast.The weak overcomes the strong."…"Everyone knows that the yielding overcomes the stiff,and the soft overcomes the hard.Yet no one applies this knowledge.

Knowledge is a treasure, but practice is the key to it.

To know and to think we know not, is the crown. Not to know and to think we know, is the affliction.

Those who have knowledge, don't predict. Those who predict, don't have knowledge

To know yet to think that one does not know is best; Not to know yet to think that one knows will lead to difficulty.
