In this paper, I argue that we do not know how to implement abstract principles of liberal egalitarian justice. Starting with Scheffler’s Rawlsian diagnosis of the retreat of liberal democracy in the United States, I argue that it may be due to our lack of knowledge about how to institutionalize a Rawlsian just liberal society. To illustrate the difficulty or challenge, I examine several policy proposals to help build human capital for property-owning democracy and argue that they can fail for various reasons. The main problem is that the changing ways in which diverse individuals respond to policies and interact with one another affect policy consequences, but their complexity surpasses our limited knowledge. The ignorance gives us reason to be patient with the slow pace of building an ideal liberal society, tolerant of those who are sceptical about interventions to implement liberal egalitarian principles, and open to policy experimentation and learning. I further argue that we should publicly acknowledge our ignorance about policy outcomes, as it can reduce political polarization, by moderating policy positions and interpreting policy disagreements as empirical rather than moral, and counter democratic backsliding.

Conversational theatre is a medium for facilitating dialog on race, privilege, and discrimination in Swedish society. Du Contrat Social, a performance based on Jean-Jacques Rousseau’s social contract, demonstrates how theatre can create an interactive space where audience members actively reflect on their social positioning and implicit biases. By guiding the audience through exercises that expose implicit stereotypes and encourage self-reflection, the performance fosters a unique setting for transformative learning.

Historians have long disregarded Hegel as a rigidly aprioristic thinker. However, they have not arrived at this view based on familiarity with his works. Usually, early on in their education, historians are taught that teleology is anathema to their craft, and that Hegel is an exemplar of this approach. As a result, they are routinely advised that his writings can safely be ignored. Nonetheless, ironically, much in Hegel’s narrative continues to be influential. He emphasized a number of seismic shifts that shaped the world over millennia—for instance, the passage from ancient paganism to modern Christianity, and from the Reformation to the Enlightenment and the French Revolution. These events, and their pivotal role, still dominate historiography. Yet despite the staying-power of much of this account, its author is still discounted among professional historians.

The purpose of this essay is to explore Adam Smith’s work for ideas relevant to modern-day discourse on pluralism (understood as methodological pluralism). It is argued here that the emphasis on difference of perspective in his theory of human nature is potentially foundational for pluralism. I explore Smith’s philosophy of science, where his theory of human nature explains the motivation for building knowledge, the conduct of enquiry, and the appraisal of resulting theories. Finally, I explore exemplars of pluralist practice in Smith’s treatment of alternative approaches to economics to his own as well as in his account of different approaches to history and astronomy.

Birds and bats are extremely adept flyers: whether in hunting prey, or evading predators, post-stall manoeuvrability is a characteristic of vital importance. Their performance, in this regard, greatly exceeds that of uncrewed aerial vehicles (UAVs) of similar scale. Attempts to attain post-stall manoeuvrability, or supermanoeuvrability, in UAVs have typically focused on thrust-vectoring technology. Here we show that biomimetic wing morphing offers an additional pathway to classical supermanoeuvrability, as well as novel forms of bioinspired post-stall manoeuvrability. Using a state-of-the-art flight simulator, equipped with a multibody model of lifting surface motion and a delay differential equation (Goman-Khrabrov) dynamic stall model for all lifting surfaces, we demonstrate the capability of a biomimetic morphing-wing UAV for two post-stall manoeuvres: a classical rapid nose-pointing-and-shooting (RaNPAS) manoeuvre; and a wall landing manoeuvre inspired by biological ballistic transitions. We show that parametric variation of nonlinear longitudinal stability profiles is an effective open-loop strategy to explore the space of post-stall manoeuvres in these types of UAVs; and it yields insight into effective morphing kinematics to enable these manoeuvres. Our results demonstrate the capability of morphing-based control of nonlinear longitudinal stability to enable complex forms of transient supermanoeuvrability in UAVs.

Peer review is part of the bedrock of science. In recent years the focus of peer review has shifted toward developmental reviewing, an approach intended to focus on the author’s growth and development. Yet, does the focus on developing the author have unintended consequences for the development of science? In this paper, we critique the developmental approach to peer review and contrast it with the constructive approach, which focuses on improvement of the research. We suggest the developmental approach, although with laudable aims, has also produced unintended consequences that negatively impact authors’ experiences as well as the quality and meaningfulness of the science published. We identify problems and discuss potential solutions that can strengthen peer review and contribute to science for a smarter workplace.
