Upshot: In our response we focus on five questions that point to important common themes in the commentaries: why start in wicked problems, what kind of system is a scientific perspective, what is the nature of second-order research processes, what does this mean for understanding interdisciplinary work, and how may polyocular research help make real-world decisions.

Upshot: In our response we focus on how different types of systems are related from a constructivist perspective, and specifically on the relation between communicational social systems and embodied agency.

Open peer commentary on the article “Social Autopoiesis?” by Hugo Urrestarazu. Upshot: We agree on the need to explore a concept of social autopoiesis that goes beyond a strictly human-centered concept of social systems as autopoietic communicative systems. But both Hugo Urrestarazu and Niklas Luhmann neglect the importance of semiosis in understanding communication, and this has important implications for the question of a more general approach to social systems.

The juvenile hormones of insects regulate an unusually large diversity of processes during postembryonic development and adult reproduction. It is a long‐standing puzzle in insect developmental biology and physiology how one hormone can have such diverse effects. The search for molecular mechanisms of juvenile hormone action has been guided by classical models for hormone–receptor interaction. Yet, despite substantial effort, the search for a juvenile hormone receptor has been frustrating and has yielded limited results. We note here that a number of (...) lipid‐soluble signaling molecules in vertebrates, invertebrates and plants show curious similarities to the properties of juvenile hormones of insects. Until now, these signaling molecules have been thought of as uniquely evolved mechanisms that perform specialized regulatory functions in the taxon where they were discovered. We show that this array of lipid signaling molecules share interesting properties and suggest that they constitute a large set of signal control and transduction mechanisms that include, but range far beyond, the classical steroid hormone signaling mechanism. Juvenile hormone is the insect representative of this widespread and diverse system of lipid signaling molecules that regulate protein activity in a variety of ways. We propose a synthetic perspective for understanding juvenile hormone action in light of other lipid signaling systems and suggest that lipid activation of proteins has evolved to modulate existing signal activation and transduction mechanisms in animals and plants. Since small lipids can be inserted into many different pathways, lipid‐activated proteins have evolved to play a great diversity of roles in physiology and development.

This book contains three essays: "The Mask and the Face: The Perception of Physiognomic Likeness in Life and Art" by Gombrich, the renowned art historian and critic; "The Representation of Things and People" by psychologist, Julian Hochberg; and "How Do Pictures Represent" by philosopher, Max Black. The book is based upon lectures delivered in the Johns Hopkins 1970 Thalheimer Lectures, where, taking off from the question "how there can be an underlying identity in the manifold and changing facial expression of (...) a single individual," there is an interdisciplinary attempt at clarifying the problem of representation. Gombrich’s central thesis is that the key to artistic representation is empathy and projection, which is guided by the interlocking display of the permanent and mobile features of the object represented. Perceptual activity and empathy rely more on the muscular imitation than on passive visual reception. He holds that what is singled out as the likeness-factor uniting the permanent and mobile features in, for example, the photograph of the four-year old Lord Russell and such factors in the ninety-year old Russell is the "general tonus, the melody of transition from given ranges of relaxations to forms of tenseness." Hochberg’s essay spells out the position that perception is purposive behavior, wherein the purpose is the information sought and behavior is the "succession of glances in different directions." Holding that perceptual activity is grounded in expectations, he lays aside Gombrich’s muscularity-thesis in favor of a learned expectation of feature characteristics. Black’s essay is a conceptual analysis of "depiction," or more precisely, of "P displays a subject S if and only if R, where R ‘will constitute the necessary and sufficient condition for P displaying S'." The essay, which proceeds in a Wittgensteinian Investigations-type fashion ends where the reader would hope it begin. He concludes that the problem can only be adequately answered by moving from logical investigation to the world of the artisan and art lover. To arrive at this conclusion he debunks six candidates that claim to meet the depiction conditions: causal history, selective information, intention, mimesis, resemblance, and "looking-like." At best, depiction may be considered a "cluster" concept of all six. Further determination, he holds, requires knowledge of the purpose of a particular depiction, and this takes us out of logic and into art; and so Black stops, unfortunately.—W. A. F. (shrink)

Evolutionary developmental biology (evo-devo) has undergone dramatic transformations since its emergence as a distinct discipline. This paper aims to highlight the scope, power, and future promise of evo-devo to transform and unify diverse aspects of biology. We articulate key questions at the core of eleven biological disciplines—from Evolution, Development, Paleontology, and Neurobiology to Cellular and Molecular Biology, Quantitative Genetics, Human Diseases, Ecology, Agriculture and Science Education, and lastly, Evolutionary Developmental Biology itself—and discuss why evo-devo is uniquely situated to substantially improve (...) our ability to find meaningful answers to these fundamental questions. We posit that the tools, concepts, and ways of thinking developed by evo-devo have profound potential to advance, integrate, and unify biological sciences as well as inform policy decisions and illuminate science education. We look to the next generation of evolutionary developmental biologists to help shape this process as we confront the scientific challenges of the 21st century. (shrink)

Prima facie knowledge is an ineradicable monster. Conceived as a relation of a mind to objects extrinsic to it, it is chimerical: for knowledge, as such, is of the real , i.e. of things as they are in se ; but the prima facie form of knowledge precludes this. Its object is a thing apprehended ab extra , i.e. as referred to a subject to which it is extrinsic. To seek to escape this impasse either by making the object intrinsic (...) to the subject, or the subject a function of the object, is to reject the prima facie character of knowledge as a relation of compresent terms. The incoherence of prima facie knowledge is that its object must be both extrinsic and intrinsic to mind—extrinsic as independently real, intrinsic as known—yet can be neither : not extrinsic since thus its inseitas is occulted, not intrinsic since thus truth is mere appearance. And this chimaera becomes a monster because knowledge is also ineradicable. We cannot know that knowledge is impossible; and, though we may be in doubt about its extancy, that very doubt is epistemic in form. It is our acceptance of the demands of knowledge that lies at the basis of our doubt; and this applies not only to legitimate doubt about the extancy of knowledge, but also to chimerical doubt about its possibility. Doubt is an inchoation of knowledge, which is thus ineradicable. (shrink)

The paper discusses Dr. Floris Tomasini's paper “What Is Bioethics: Notes toward a New Approach?”. Based on Tomasini's account of methodological and ethical pluralism, the paper explores the demarcation problem of bioethics and suggests a full methodological laissez-faire.

This study aims to examine the development of diversity and inclusion (D&I) literature and identify its prominent themes and blind spots. The research was conducted using bibliometric analysis on the Web of Science database and included 2510 publications. Results showed that the development of D&I literature had increased exponentially since the 1960s, mainly due to different political and societal events. The geographic development showed that research was primarily conducted in developed countries where quotas and other legislation are implemented. The thematic (...) development revealed a stable but narrow focus on diversity management, board diversity, and team diversity, with little attention to inclusion. The keyword analysis strongly emphasized surface-level diversity, such as gender, race, and cultural diversity, while deep-level diversity received less attention. This study concludes that previous D&I literature has mainly focused on the financial effects of D&I and neglected other elements, such as the effects on social performance, its ethical implications, and the relationship between diversity and inclusion. The study recommends future research to expand the interpretation of diversity, examine the relationship between diversity and inclusion, and explore the effects of diversity on non-financial outcomes such as social performance and ethics. This study provides a valuable contribution to the field of business ethics by highlighting the blind spots in D&I literature and encouraging future research to consider the ethical implications of diversity in the workplace.
