To know and not to act is not yet to know.
知而不行、只是未知。

Philosophers
Wang Yangming
Born in 1472 in Zhejiang during China's Ming dynasty, Wang Yangming was a Confucian scholar and military strategist. He overturned the orthodox Neo-Confucian doctrine of 'first knowledge, then action' with his thesis that knowledge and action are inseparable — the 'unity of knowing and acting.' His school of thought, Yangming studies, influenced Japanese reformers from Oshio Heihachiro to Yoshida Shoin.
