Abstract

To better understand the knowledge of language we study how it interacts with other kinds of knowledge in the performance of different abilities and their corresponding knowledge structures, for example in reading and writing or in comparing prose and singing. The more difficult study is to gain a better understanding of how language emerged in our species. Comparative research with other species focused on communication, especially when expression is vocal and reception is auditory, may help us to formulate the right questions. In the comparisons in which the mechanisms of communication and aspects of the underlying knowledge are learned, another dimension of the research program presents itself. A recent survey of the field by Nicolas Mathevon maps out some of the main results of this research in The Voices of Nature: How and Why Animals Communicate (2023). The following review essay will be selective, as the survey is wide-ranging and covers related topics that will take us too far, even though they are, ultimately, related.
