As human epistemology is concerned, there are at least five kinds of natural basic means for human to know about the universe: sensibility (time-space, algebra, geometry and all sensory abilities of human), intellectuality, aesthetic appreciation and aesthetic purposiveness and supreme rationality, which constitute the connection between subject and object. People use these basic ways to recognize themselves and all things in the universe.
