". . . That Thou Art Mindful of Him" (also signed as "That Thou Art Mindful of Him") is a science fiction short story by American writer Isaac Asimov, which he intended to be an "ultimate" probe into the subtleties of his Three Laws of Robotics. The story first appeared in the May 1974 issue of Fantasy and Science Fiction and the 1974 anthology Final Stage, edited by Edward L. Ferman and Barry N. Malzberg. It was collected in The Bicentennial Man and Other Stories (1976) and The Complete Robot (1982). Plot summary In this story, Asimov describes U.S. Robots' attempt to introduce robots on the planet Earth. Robots have already been in use on space stations and planetary colonies, where the inhabitants are mostly highly trained scientists and engineers. U.S. Robots faces the problem that on Earth, their robots will encounter a wide variety of people, not all of whom are trustworthy or responsible, yet the Three Laws require robots to obey all human orders and devote equal effort to protecting all human lives. Plainly, robots must be programmed to differentiate between responsible authorities and those giving random, whimsical orders. The Director of Research designs a new series of robots, the JG series, nicknamed "George", to investigate the problem. The intent is that the George machines will begin by obeying all orders and gradually learn to discriminate rationally, thus becoming able to function in Earth's society. As their creator explains to George Ten, the Three Laws refer to "human beings" without further elaboration, but—quoting Psalm 8:4—"What is Man that thou art mindful of Him?" George Ten considers the issue and informs his creator that he cannot progress further without conversing with George Nine, the robot constructed immediately before him. Together, the two Georges decide that human society must be acclimated to a robotic presence. They advise U.S. Robots to build low-function, non-humanoid machines, such as electronic birds and insects, which can monitor and correct ecological problems. In this way, humans can become comfortable with robots, thereby greatly easing the transition. These robotic animals, note the Georges, will not even require the Three Laws, because their functions will be so limited. The story concludes with a conversation between George Nine and George Ten. Deactivated and placed in storage, they can only speak in the brief intervals when their power levels rise above the standby-mode threshold. Over what a human would
