Megan Steigerwald Ille, "Opera for Everyone: The Industry's Experiments with American Opera in the Digital Age"
English | ISBN: 0472076647 | 2024 | 308 pages | PDF | 3 MB
Opera for Everyone: The Industry's Experiments with American Opera in the Digital Age draws on seven years of multi-sited ethnography to examine the acclaimed experimental productions of Los Angeles-based opera company The Industry. Steigerwald Ille understands The Industry's productions as part of an emerging wave of U.S. operas that integrate new media and interactive performance through means such as site-specificity and simulcast video, and then traces the company's path from Crescent City (2012), the company's first production, to Sweet Land (2020), the company's final production before switching to a new production model. Steigerwald Ille argues that by moving opera outside of the opera house, The Industry's productions expose the economic and aesthetic structures key to the circulation of operatic performance at the same time that they deploy opera as a tool for digital listening, community engagement, popular entertainment, and commentary on systemic racism and settler colonialism. Through ethnographic work with The Industry's creators and performers, and close examination of the company's first decade of work, this book reveals how The Industry paradoxically provides both a roadmap and boundary line for experimental and traditional companies trying to find new ways to approach operatic performance in the twenty-first century United States.

Opinion Pooling (Elements in Decision Theory and Philosophy)
by Lee Elkin and Richard Pettigrew
English | 2024 | ISBN: 1009494414 | 106 Pages | True PDF | 2.7 MB

Disagreement is a common feature of a social world. For various reasons, however, we sometimes need to resolve a disagreement into a single set of opinions. This can be achieved by pooling the opinions of individuals that make up the group. In this Element, we provide an opinionated survey on some ways of pooling opinions: linear pooling, multiplicative pooling (including geometric), and pooling through imprecise probabilities. While we give significant attention to the axiomatic approach in evaluating pooling strategies, we also evaluate them in terms of the epistemic and practical goals they might meet. In doing so, we connect opinion pooling to some philosophical problems in social epistemology and the philosophy of action, illuminating different perspectives one might take when figuring out how to pool opinions for a given purpose.

Optimal Control: Calculus of Variations, Optimal Control Theory and Numerical Methods by R. Bulirsch, A. Miele, J. Stoer, K. Well
English | PDF | 1993 | 352 Pages | ISBN : 303487541X | 22.1 MB
"Optimal Control" reports on new theoretical and practical advances essential for analysing and synthesizing optimal controls of dynamical systems governed by partial and ordinary differential equations. New necessary and sufficient conditions for optimality are given. Recent advances in numerical methods are discussed. These have been achieved through new techniques for solving large-sized nonlinear programs with sparse Hessians, and through a combination of direct and indirect methods for solving the multipoint boundary value problem. The book also focuses on the construction of feedback controls for nonlinear systems and highlights advances in the theory of problems with uncertainty. Decomposition methods of nonlinear systems and new techniques for constructing feedback controls for state- and control constrained linear quadratic systems are presented. The book offers solutions to many complex practical optimal control problems.

Optimism and the Best Possible World: A Philosophical History
by Justin J. Daeley
English | 2025 | ISBN: 1032463104 | 273 Pages | True PDF | 1.78 MB

This volume presents original essays on the ideas of philosophical optimism and the best possible world. It highlights the historical and philosophical nuances of an idea that remains under-treated within the literature despite its long and influential history.
Optimism―broadly, the thesis that God does the best, or that this is the best possible world―is often associated with the philosophy of Gottfried Wilhelm Leibniz. However, there exists a rich tradition of philosophical optimism not only after Leibniz but before him as well. The chapters in this volume address the philosophical nuances of optimism within the ancient, medieval, enlightenment, modern, and contemporary eras. They cover a variety of thinkers ranging from Plato, Aquinas, Rousseau, Voltaire, Jonathan Edwards, the new optimists of 19th-century France, and the non-theistic optimists of the 20th century.
Optimism and the Best Possible World will be of interest to scholars and advanced students working in philosophy of religion, history of philosophy, religious history, and intellectual history.

Optimistic Nihilism: A Psychologist's Personal Story & (Biased) Professional Appraisal of Shedding Religion By David Landers
2016 | 302 Pages | ISBN: 069244078X | EPUB | 1 MB
Through surprisingly good storytelling, David "Don't Call Me Doctor" Landers takes us on a captivating spiritual adventure as he walks us through his personal evolution from dedicated Christian to devout atheist. But much more than autobiography, his story is woven with provocative psychological and philosophical commentary, including input from the likes of Lucretius, Freud, and the metal band Napalm Death. A rare style of intellectual but conversational and poignant but humorous makes for a highly accessible and enjoyable read. As the spiritual account winds down, the book transitions into a more rational exploration of the problems associated with religion-and even with spirituality in general. Everyone from outspoken atheists to moderate believers will be engaged, as David is able to critically evaluate spirituality without the hostility so common among modern atheist writers. At the book's climax, David develops the popular atheist conversation a little deeper by courageously exploring the implications of nihilism: If our deepest fears about the nature of reality were to be true, could we go on? By the end of Optimistic Nihilism, we begin to suspect that we could-and even wonder if a relatively nihilistic perspective paradoxically makes life more precious than any other scheme. A critical must-read for all students of spirituality, psychology, and humanity.

Orage's Commentary on Gurdjieff's Beelzebub's Tales to His Grandson: New York Talks 1926-1930 By A. R. Orage , Lawrence Morris (editor), Sherman Manchester (editor)
2020 | 310 Pages | ISBN: 0957248105 | EPUB | 1 MB
A student asked: I have heard the phrase "listening to the book in all three centers" and I am not clear on how it can be done.Orage: It isn't a matter of how it can be done, but of understanding what it means and then wishing to hear the book that way. Remember how you listened to stories you heard when you were a child, so that you participated, your hair stood on end and your eyes shone or you wept? That is reading with all three centers, and Gurdjieff would hope the book reading could be of that order.A. R. Orage's commentaries on Beelzebub's Tales to His Grandson are an essential part of the Fourth Way literature. They demonstrate a way of approaching and understanding a work that Orage considered to be literature of the highest kind. As the figures in Beelzebub are mythological and their language, parabolical, the book may not be easily comprehensible by the average reader or Fourth Way beginner. Orage's commentaries help to clarify and simplify the important lessons in the book by serving as keys to understanding Beelzebub which, as Gurdjieff once said, are all in the book, but not near their locks. Available to the reader for the first time in its entirety, this present volume promises a multifaceted illumination of Beezlebub.

Order and the Virtual: The Philosophy and Science of Deleuzian Cosmology by Bill Ross
English | June 30, 2024 | ISBN: 1399527355 | True EPUB | 240 pages | 0.4 MB
Bill Ross demonstrates the relation between Gilles Deleuze's philosophy of difference and the conceptual foundations of contemporary physics through careful engagements with the theory of relativity, quantum physics and chaos and complexity theory. Ross shows that recent work in cosmology by figures such as Lee Smolin and David Bohm calls into question the assumption that the laws of physics are universal and unchanging, a view that Deleuze anticipates. The second law of thermodynamics tells us that order in the universe as a whole is destined to break down. Against this, Ross demonstrates that given Deleuze's conception of the event as an expression of non-locality, and his emphasis on dissymmetry over symmetry, at the cosmological scale the universe is not destined towards disorder: evolution outruns entropy.
