The impossibility of testing the depth hypothesis of 1960 of a connection
between the complexities of grammar and a limited human temporary memory
led to questioning the ancient grammatical foundations of linguistics and
to developing standard hard-science foundations. This volume is the first
detailed report on how to reconstitute linguistics on the new hard-science
foundation laid by Victor H. Yngve in 1996.
Hard-science (human) linguistics is the scientific study of how people
communicate. It studies people and also communicative energy flow and other
relevant parts of the physical environment. It studies the real world, not
the world of language, and it develops theories testable against real-world
evidence as is standard in the hard sciences. Hard-science linguistics
takes its rightful place connecting the humanities and social sciences to
biology, chemistry and physics. Thus linguistics becomes a natural science
and contributes to the unity of science. This unity is clearly evident in
the research reported here by these fifteen pioneering authors from diverse
areas as they work to reconstitute linguistics as a true hard science.
