Looking for accidental signs of truth in the confused and confused sea of Wang Yang requires a clear head, selfless work enthusiasm and strong fighting spirit. We have created a global civilization in which the most important elements are closely related to science and technology. However, this is a recipe for disaster. Ignorance and power mixed flammable products will one day burn into a raging fire in front of us. Especially at the end of this Millennium, pseudoscience and superstition seem to be more and more attractive, and the irrational siren's song is more pleasant and charming. Have we heard this song somewhere before? When material resources are scarce, when national pride or sensitive issues are challenged, when we are extremely worried about losing our position and purpose in the universe, and when fanatical flames are boiling around us, I am worried that our thinking habits will control everything for a long time.
