Not every presidential visit to the theatre is as famous as Lincoln's last night at Ford's, but American presidents attended the theatre long before and long after that ill-fated night. In 1751, George Washington saw his first play, The London Merchant, during a visit to Barbados. John Quincy Adams published dramatic critiques. William McKinley avoided the theatre while in office, on professional as well as moral grounds. Richard Nixon met his wife at a community theatre audition. Surveying 255 years, this volume examines presidential theatre-going as it has reflected shifting popular tastes in America.
The subject “Systems sciences and cybernetics” is the outcome of the convergence of a number of trends in a larger current of thought devoted to the growing complexity of (primarily social) objects and arising in response to the need for globalized treatment of such objects. This has been magnified by the proliferation and publication of all manner of quantitative scientific data on such objects, advances in the theories on their inter-relations, the enormous computational capacity provided by IT hardware and software and the critical revisiting of subject-object interaction, not to mention the urgent need to control the efficiency of complex systems, where “efficiency” is understood to mean the ability to find a solution to many social problems, including those posed on a planetary scale. The result has been the forging of a new, academically consolidated scientific trend going by the name of Systems Theory and Cybernetics, with a comprehensive, multi-disciplinary focus and therefore apt for understanding realities still regarded to be inescapably chaotic. This subject entry is subdivided into four sections. The first, an introduction to systemic theories, addresses the historic development of the most commonly used systemic approaches, from new concepts such as the so-called “geometry of thinking” or the systemic treatment of “non-systemic identities” to the taxonomic, entropic, axiological and ethical problems deriving from a general “systemic-cybernetic” conceit. Hence, the focus in this section is on the historic and philosophical aspects of the subject. Moreover, it may be asserted today that, beyond a shadow of a doubt, problems, in particular problems deriving from human interaction but in general any problem regardless of its nature, must be posed from a systemic perspective, for otherwise the obstacles to their solution are insurmountable. Reaching such a perspective requires taking at least the following well-known steps: a) statement of the problem from the determinant variables or phenomena; b) adoption of theoretical models showing the interrelationships among such variables; c) use of the maximum amount of – wherever possible quantitative – information available on each; d) placement of the set of variables in an environment that inevitably pre-determines the problem. That epistemology would explain the substantial development of the systemic-cybernetic approach in recent decades. The articles in the second section deal in particular with the different methodological approaches developed when confronting real problems, from issues that affect humanity as a whole to minor but specific questions arising in human organizations. Certain sub-themes are discussed by the various authors – always from a didactic vantage –, including: problem discovery and diagnosis and development of the respective critical theory; the design of ad hoc strategies and methodologies; the implementation of both qualitative (soft system methodologies) and formal and quantitative (such as the “General System Problem Solver” or the “axiological-operational” perspective) approaches; cross-disciplinary integration; and suitable methods for broaching psychological, cultural and socio-political dynamisms. The third section is devoted to cybernetics in the present dual meaning of the term: on the one hand, control of the effectiveness of communication and actions, and on the other, the processes of self-production of knowledge through reflection and the relationship between the observing subject and the observed object when the latter is also observer and the former observed. Known as “second order cybernetics”, this provides an avenue for rethinking the validity of knowledge, such as for instance when viewed through what is known as “bipolar feedback”: processes through which interactions create novelty, complexity and diversity. Finally, the fourth section centres around artificial and computational intelligence, addressing sub-themes such as “neural networks”, the “simulated annealing” that ranges from statistical thermodynamics to combinatory problem-solving, such as in the explanation of the role of adaptive systems, or when discussing the relationship between biological and computational intelligence.
Wishing to ingratiate himself with Rome, Herod the Great built theaters, amphitheaters, and hippodromes to bring pagan entertainments of all sorts to Palestine. Zeev Weiss explores how the indigenous Jewish and Christian populations responded, as both spectators and performers, to these cultural imports, which left a lasting imprint on the region.
The seventeenth-century Mexican poet, playwright and nun, Sor Juana Inés de la Cruz, is best known for her secular works, most notably her damning indictment of male double standards, Hombres necios (Stupid Men). However, her autos sacramentales (allegorical one-act plays on the Eucharist) have received little attention, and have only been discussed individually and out of sequence. By examining them as a collection, in their original order, their meaning and importance are revealed. The autos combine Christian and classical ‘pagan’ imagery from the ‘Old World’ with the conquest and conversion of the ‘New World’. As the plays progress, the mystery of Christ’s ‘greatest gi ft’ to mankind is deciphered and is mirrored in Spain’s gi ft of the True Faith to the indigenous Mexicans. Sor Juana’s own image is also situated within this baroque landscape: presented as a triumph of Spanish imperialism, an exotic muse between two worlds.
