Man is rational, he can think, he has the ability of logical thinking, he is the synthesis of all social relations, and he is an animal! The most fundamental difference between people and animals is that they have feelings. People feel differently. My happiness is being with you. Maybe sometimes I will be happy, maybe sometimes I will be sad, sometimes I will be miserable, sometimes I will be depressed, I will be ecstatic, I will be ecstatic. My love is bound to have climax, trough, passion and silence. This kind of love is true love. Thought is the soul of human beings and the fundamental difference between human beings and animals. People are human because they have thoughts, but animals don't. The reason why people have thoughts is because people have transcendence. A person's life is a process of transcending reality and moving towards an ideal life. The process of pursuing and moving towards ideals makes people become real people. A person without thoughts is not a complete person, but an incomplete person. Thought makes people elegant and sublime. Mediocre people only know the pursuit of material wealth, but they don't know the nobility and elegance of spiritual life. They live in material desires and don't know the meaning and value of life. People in the true sense not only know the abundance of material life, but also know the sublimity of spiritual life. Man is for happy animals and reproduction, nothing more. ....
