The premise of Studies in Irreversibility: Texts and Contexts is that there is a big difference between phenomena, practices, processes, and events that are irreversible and those that are reversible, and moreover that this difference and its manifold implications remain underappreciated so long as the analysis of culture continues to anchor itself in an emphasis on the capacities of human agency. If messianic modes posit a future to justify the present, and so interpret the influence of the past, the papers in this collection are devoted to examining the present of experience from the perspective of its uncompromising and irreducible past, finding in irreversibility a key to an interpretation of futurity. Together, these papers outline a method of examining experience as something more—or at least other—than the desire to know it, and in so doing they shed light on the powerful role of normativity in the narratives we construct in and about culture. Through novel analyses from the disciplines of literature, art criticism, history, philosophy, ethnic studies, and ethics, the contributors to this book address key questions about the nature of irreversibility: What differentiates the experience of the irreversible from the experience of the reversible? How is irreversibility recognized? What happens when we acknowledge something to be irreversible? How has society contended with irreversibility, and what sorts of tools exist today to interpret its significance? Wary of impetuously fixing the meaning of a still-elusive concept, this volume collects papers that employ a wide array of methodologies, mindful that no one critical approach may yet have proved itself. Irreversibility is not simply a quality of the texts examined in this volume, nor is it strictly speaking a lens through which otherwise coherent or stable texts are examined; rather, it emerges as a model that brings together texts and the thinking of them. By together outlining a method of examining culture that moves beyond reliance on tropes such as functionalism, teleology, and chance, tropes that have dominated twentieth century cultural analysis, these papers help to inaugurate a new paradigm in the study of culture.

After an insightful introductory part on recent developments in the thermodynamics of small systems, the author presents his contribution to a long-standing problem, namely the connection between irreversibility and dissipation. He develops a method based on recent results on fluctuation theorems that is able to estimate dissipation using only information acquired in a single, sufficiently long, trajectory of a stationary nonequilibrium process. This part ends with a remarkable application of the method to the analysis of biological data, in this case, the fluctuations of a hair bundle. The third part studies the energetics of systems that undergo symmetry breaking transitions. These theoretical ideas lead to, among other things, an experimental realization of a Szilard engine using manipulated colloids. This work has the potential for important applications ranging from the analysis of biological media to the design of novel artificial nano-machines.

The problem of deriving irreversible thermodynamics from the re versible microscopic dynamics has been on the agenda of theoreti cal physics for a century and has produced more papers than can be digested by any single scientist. Why add to this too long list with yet another work? The goal is definitely not to give a gen eral review of previous work in this field. My ambition is rather to present an approach differing in some key aspects from the stan dard treatments, and to develop it as far as possible using rather simple mathematical tools (mainly inequalities of various kinds). However, in the course of this work I have used a large number of results and ideas from the existing literature, and the reference list contains contributions from many different lines of research. As a consequence the reader may find the arguments a bit difficult to follow without some previous exposure to this set of problems.

NAMED A BOOK OF THE YEAR BY THE ECONOMIST AND ONE OF THE BEST BOOKS OF 2021 BY THE TIMES AND THE SUNDAY TIMES "Irreversible Damage . . . has caused a storm. Abigail Shrier, a Wall Street Journal writer, does something simple yet devastating: she rigorously lays out the facts." —Janice Turner, The Times of London Until just a few years ago, gender dysphoria—severe discomfort in one’s biological sex—was vanishingly rare. It was typically found in less than .01 percent of the population, emerged in early childhood, and afflicted males almost exclusively. But today whole groups of female friends in colleges, high schools, and even middle schools across the country are coming out as “transgender.” These are girls who had never experienced any discomfort in their biological sex until they heard a coming-out story from a speaker at a school assembly or discovered the internet community of trans “influencers.” Unsuspecting parents are awakening to find their daughters in thrall to hip trans YouTube stars and “gender-affirming” educators and therapists who push life-changing interventions on young girls—including medically unnecessary double mastectomies and puberty blockers that can cause permanent infertility. Abigail Shrier, a writer for the Wall Street Journal, has dug deep into the trans epidemic, talking to the girls, their agonized parents, and the counselors and doctors who enable gender transitions, as well as to “detransitioners”—young women who bitterly regret what they have done to themselves. Coming out as transgender immediately boosts these girls’ social status, Shrier finds, but once they take the first steps of transition, it is not easy to walk back. She offers urgently needed advice about how parents can protect their daughters. A generation of girls is at risk. Abigail Shrier’s essential book will help you understand what the trans craze is and how you can inoculate your child against it—or how to retrieve her from this dangerous path.

Adjustment Costs, Irreversibility and Investment Patterns in African Manufacturing

This paper examines dynamic patterns of investment in Cameroon, Ghana, Kenya, Zambia and Zimbabwe, assessing the consistency of those patterns with different adjustment cost structures. Using survey data on manufactured firms, we document the importance of zero investment episodes and lumpy investment. The proportion of firms experiencing large investment spikes is significant in explaining aggregate manufacturing investment. Taken together, evidence from descriptive statistics, average investment regressions modeling the response to capital imbalance, and transition data analysis indicate that irreversibility is an important factor considered by firms when making investment plans. The picture is not unanimous however, and some explanations for the mixed results are proposed.

A dominant feature of our ordinary experience of the world is a sense of irreversible change: things lose form, people grow old, energy dissipates. On the other hand, a major conceptual scheme we use to describe the natural world, molecular dynamics, has reversibility at its core. The need to harmonize conceptual schemes and experience leads to several questions, one of which is the focus of this book. How does irreversibility at the macroscopic level emerge from the reversibility that prevails at the molecular level? Attempts to explain the emergence have emphasized probability, and assigned different probabilities to the forward and reversed directions of processes so that one direction is far more probable than the other. The conclu sion is promising, but the reasons for it have been obscure. In many cases the aim has been to find an explana tion in the nature of probability itself. Reactions to that have been divided: some think the aim is justified while others think it is absurd.

Panel data on Ghanaian manufacturing firms are used to test predictions from models of irreversible investment under uncertainty. Information on the entrepreneur’s subjective probability distribution over future demand for the firm’s products is used to construct the expected variance of demand, which is used as a measure of uncertainty. Empirical results support the prediction that firms wait to invest until the marginal revenue product of capital reaches a firm-specific hurdle level. Moreover, higher uncertainty raises the hurdle level that triggers investment, and uncertainty has a negative effect on investment levels that is greater for firms with more irreversible investment.

Irreversibility and Aggregate Investment

Investment is often irreversible, in that installed capital has little or no value unless used in production. In the presence of ongoing uncertainty, an individual firm's irreversible investment policy optimally alternates short bursts of positive gross investment to periods of inaction, when the installed capital stock is allowed to depreciate. The behavior of aggregate investment series is characterized by sluggish, continuous adjustment instead. We argue in this paper that aggregate dynamics should be interpreted in terms of unsynchronized irreversible investment decisions by heterogenous firms, rather than in terms of ad-hoc adjustment cost functions in a representative-agent framework. We propose a closed-form solution for a realistic model of sequential irreversible investment, characterize the aggregate implications of microeconomic irreversibility and idiosyncratic uncertainty, and interpret U.S. data in light of the theoretical results.

The character of this work is perhaps sufficently indicated by its title. However it must be noted that the term "philosophy" is not used so strictly as to exclude material from other disciplines connected with philosophy or helpful to it and to an unders
