Givan a set of requirements for a difinition of communication, we can
define a communication as information that enters a process and eventually
leaves its inverse process. For example, information is transmitted by speaking
and received after processing by its inverse, hearing. This definition can be
used to precisely describe and explain communication phenomena in an inclusive
and exact manner. The nature of processes and their development is considered.
Communication processes may support other processes, including noncommunicative,
evolutionarily adaptive processes supporting survival and reproduction.
Communication is expected to develop in selforganizing systems, given certain
assumptions. Receiving processes may be understood as information filters and
their performance described, predicted, and understood. These precise
definitions of communication and information can serve as the basis for a
science of librarianship.
