Abstract

I argue that meaning is a result of our biological evolution, and that language evolved from primates’ ability to grasp conceptually the most important features of their environment. I hold that natural selection and adaptation ensure that primates both sense and conceptualize their world similarly, and that they therefore think similarly, whenever they receive the same sense impressions. This cognitive similarity enabled our predecessors to learn and develop a language because of the regular association of a particular sound and a particular image. The evolutionary pressure on our predecessors to develop a language was the advantage that such a language had for cooperation and survival. Finally, I argue that the old, but in wider circles frowned-upon theory of meaning, the expressive theory of language, provides the best explanation of the relationship between thought, meaning, and words, because it operates with words and not sentences as the basic semantic unit.
