What does philosophy study?

The so-called philosophy is based on the basic principle of cultural exchange, that is, all questions are raised by applied language and all questions must be answered by language. At the level of language application research, the author makes a comprehensive study of word formation, word formation, group syntax, argument and conclusion, and uses the wisdom of newly applied language to organize all human knowledge into the academic framework of interpersonal communication and common language application law, so as to achieve smooth communication and good knowledge cohesion. Therefore, the so-called philosophy is an applied law that studies theoretical language.

At the level of interpersonal cultural communication, all right and wrong are academic criticism issues, and all academic criticism issues are based on the right and wrong of applied language. Right or wrong, the basis of criticism is "statement". There is no right or wrong in academic criticism except "statement". This is a disproof of the content of philosophical research.
