This article talks about how words and text are a kind of artificial virus similar to biological viruses. The survival, growth and evolution of this artificial virus and its mechanism of harm to humans are very similar to biological viruses. What is different is how this mental virus threatens people’s lives and health is not through the body but through the mind. Regarding mental threat, the author believes that human Self-nature should be fully mobilized to enhance the immunity of human spirit, and art is an ideal way to mobilize human beings’ nature of Self. In addition, the author also believes people can also use this kind of mental virus reasonably, so that it can become a mental vaccine to prevent the human mind from being violated.
