The intelligence can answer the four basic questions of"where","what","why"and"how to do"in the whole cognitive activity,which contains rich content.Currently,there is still no recognized standard definition of"intelli-gence".This paper analyzes this dilemma and gives a new 33-word definition of"intelligence",which no longer distin-guishes between human intelligence and machine intelligence,and makes intelligence no longer be entangled by con-sciousness,desire,emotion Character,etc.The definition emphasizes the importance of learning,especially the percep-tual intelligence and behavioral intelligence caused by the embodied interactions in the physical space,and the computa-tional intelligence and memory intelligence caused by the thinking in the cognitive space.When intelligence is released from the body and placed in a machine,it becomes artificial intelligence.Human cognition and imagination,human learning ability,as well as the ability to explain and solve problems,the iterative development of human intelligence and artificial intelligence,enable intelligence to grow at the speed of supernatural evolution.Human beings are entering the era of intelligence.
