This article presents the systems sciences as a field of inquiry and d
iscusses the way in which it has evolved in relation to the humanities
. Following a brief historical overview and assessment of the systems
sciences by considering their origins and foundations in general syste
m thinking, the review highlights the key players and the major trends
in the field, and leads to a consideration of the ways in which it co
mplements and contrasts the methods of human-related studies generally
pursued in the humanities. It discusses the potential for the systems
sciences to enrich descriptive, instructional, and explanatory orient
ations of contemporary Geisteswissenschaften through the inclusion of
normative considerations. The normative component of the systems scien
ces is considered within an evolutionary framework that presents holis
m as a methodology for understanding the dynamics of complex 'real-wor
ld' (ontological) systems and suggests action imperatives for their vi
able and sustainable design over time. Through the tools metaphor, mod
eling and simulation, interactive design and other praxes, systems sci
entists investigate the goals and ends of systems and their interactio
ns within environments shared with, and provided for, one another. In
this way social systems in general, and human activity systems in part
icular, can be described as a function of their degree of purposefulne
ss in terms of the role of human values in concrete circumstances. Thr
ough the tools of systems analysis and design, systems science represe
nts the world of symbols, values, social entities, and cultures as emb
edded in an embracing order of hierarchies that bridges the gap betwee
n C. P. Snow's Two Cultures' of the sciences and the humanities. The u
se of modeling in systems sciences provides the language of design and
the means by which creativity is applied in the course of inventing,
making, assessing, and implementing the designs. In this way it lends
to the humanities the capability to deal with increasing systemic comp
lexities, rapid societal changes, and design decisions that affect the
sustainable evolution of human societies within the wider context of
their life support systems.
