The theme of the book is how ought
artificial phenomena be categorized, discussing as to whether such phenomena belong within the domain of 'science'. Simon characterizes an artificial
system as an interface that links two environments—inner and outer. Therefore, artificial systems are susceptible to change because they are contingent upon their environment, i.e. the circumstances in which they are in. Moreover, these environments exist in the realm of '
natural science', while the interface is the realm of 'artificial science'.Such fields also include those of
cognitive psychology,
linguistics, economics,
management/administration, and
education. As such, Simon explores the commonalities of artificial systems including
economic systems, business firms, artificial intelligence, complex engineering projects, and
social plans. The book ultimately provides an
information-processing theory of humanity's
thinking processes as an operational, empirically based alternative to
behaviorism. ==Influence==
