Mo-Tzu (mô-dzŭ) or Mo Ti (mô dē), c.470 BC–391 BC, Chinese philosopher. His teachings, found in The Mo Tzu, emphasize universal love—that people should love all others as they love their own families and states. He also advocated moderation in social affairs, including funeral rites. At first a rival of Confucianism, Moism vastly declined in influence after about 200 years.
See his basic writings, tr. by B. Watson (1963).
c. 470-c. 391 b.c.
Chinese philosopher, also known as Mo ti, who provided what may be the earliest account of a camera obscura. In about 400 b.c. Mo-tzu observed reflected light rays from an illuminated object passing through a pinhole into a otherwise completely dark room. He noted that these create a precisely inverted image of the original object. More than 2,200 years later, this principle would influence the development of the camera.
