明代羅欽順認為，“格物”就係人對於外界事物嘅認識，亦即係“學問為主，而思辨輔之”。“致知”，就係當人進行思辨時所產生嘅理性活動，以“思辨為主，而學問輔之”。如果冇咗格物，唔去接觸外界事物，呢個認識就只不過係空想；冇咗致知，就會被各種事物嘅現象迷惑，所以呢兩樣嘢一定要互相補足。
Luo Qinshun of the Ming Dynasty believed that Lin Gewu uranium is people's understanding of external things, that is, general knowledge is the mainstay, and speculation is supplemented. Lin Zhi Zhi Mo is the rational activity that arises when people are speculating, with Lin thinking as the main thing, and learning as a supplement. If there is no object, if we do not come into contact with external things, this understanding is nothing but a fantasy, and without enlightenment, we will be confused by the phenomena of various things, so these two things must complement each other.
