Charles Morris was an American philosopher and psychologist known for his work in the field of semiotics, which is the study of signs and symbols. He contributed significantly to the understanding of how meaning is created and communicated through language and other forms of representation. His theories emphasized the importance of context in interpreting signs. Morris was also involved in the development of behaviorism, a psychological approach that focuses on observable behaviors rather than internal mental states. His work laid the groundwork for later developments in both psychology and linguistics, influencing figures such as B.F. Skinner and Noam Chomsky.
