(Thinking and language)

The relationship between thinking and language is an issue concerned by linguists, anthropologists, psychologists, philosophers, neuroscientists and even artificial intelligence (AI) specialists. However, it remains a problem without an agreeable and unimpeachable solution. Faced with such a situation, the author tries to explain the relationship between thinking and language by comparing the non-homology and asynchronism of the evolution and development between thinking and language, by exploring thinking with and without language, and by probing into slips of tongue and their causes, which not only contributes to the understanding of their relationship, but also promotes the knowledge of human cognition
