Can you explain Harris's thoughts on integrational linguistics ?

Roy Harris was a linguistics professor who spent the past 25 years researching the development of an integrative approach to signs and semiological systems. He believed that this research was essential to all human communication. He also believed that by looking at both current educational practices combined with traditional views on linguistics we can form a more comprehensive understanding of interpersonal relations.  According to Roy Harris, "Integrationism has important implications for our understanding of interpersonal relations, as well as of modern society and its communicational resources, including the entire range of arts and sciences." 
Harris was a proponent of the idea that all communication demands constant creative activity, even communication which seems very trivial and unimportant at the time. Not only must you communicate something or "transmit" a message, you must also set up conditions under which the communication will be received in the way that you desire it to be. It requires preparation and open-endedness.
He also pointed out the fact that communication takes time.  Its basic function is to integrate our past experiences with our present ones, and, in order to do that, human beings must be capable of recognizing the integrative process. If we were unable to, no language would be possible! Any signs that we perceive cannot come without context; in other words, signs do not predate communication; it is the other way around. Without language, signs would not exist. This is quite contrary to traditional semiology. 
Finally, he believed that we must reject the theories of traditional linguistics and the static models which it employs, once and for all. These theories, which claim that communication is a system which exists outside the realm of the individual, are harmful to our understanding of communication and interpersonal relations and can hinder our ability to explain linguistic change or unique phenomena which may have occurred throughout history.
