Lack of guidance and regulation for authorizing medical cannabis for conditions involving the health and neurodevelopment of children is ethically problematic as it promulgates access inequities, risk-benefit inconsistencies, and inadequate consent mechanisms. In two virtual sessions using participatory action research and consensus-building methods, we obtained perspectives of stakeholders on ethics and medical cannabis for children and youth. The sessions focused on the scientific and regulatory landscape of medical cannabis, surrogate decision-making and assent, and the social and political culture of medical (...) cannabis. We found that evidence-gathering and data dissemination, pressures on clinical relationships, and the lack of integration of culturally diverse perspectives and Indigenous knowledges were key areas of concern. Participants emphasized the importance of utilizing adaptive study designs, highlighted the importance of trust-building between clinicians, patients and caregivers, and discussed barriers including historical and ongoing stigmatization of medical cannabis. We conclude that continued public consultation and strength-based research that integrate diverse perspectives are critical steps forward. (shrink)

For those who teach students in psychology, education, and the social sciences, the _Handbook of Demonstrations and Activities in the Teaching of Psychology, Second Edition_ provides practical applications and rich sources of ideas. Revised to include a wealth of new material, these invaluable reference books contain the collective experience of teachers who have successfully dealt with students' difficulty in mastering important concepts about human behavior. Each volume features a table that lists the articles and identifies the primary and secondary courses (...) in which readers can use each demonstration. Additionally, the subject index facilitates retrieval of articles according to topical headings, and the appendix notes the source as it originally appeared in _Teaching of Psychology_, the official journal of the Society for the Teaching of Psychology, Division Two of the American Psychological Association. Volume I consists of 97 articles about strategies for teaching introductory psychology, statistics, research methods, and the history of psychology classes. Divided into four sections, the book suggests ways to stimulate interest, promote participation, grasp psychological terminology, and master necessary scientific skills. (shrink)

Hegel is commonly understood to have required that the philosophy of history must be retrospective and therefore fundamentally conservative. Yet at the same time he is thought to have claimed that his system involved an absolute truth beyond which no philosophy could advance, and that it therefore marked the end of the history of philosophy. The two claims are evidently inconsistent, since a history of philosophy, which must be bound by constraints on the philosophy of history, could not legitimately comment (...) on philosophy's future. If this is the result of Hegel's metaphilosophy then he has contributed at least this much to his reputation for presumption and incoherence. However, I will argue that both claims are based upon misinterpretations that follow from inattention to Hegel's ontology, and that his metaphilosophy is more subtle and more critical than most interpreters have allowed. Though Hegel clearly requires that a philosophy draw its content from its time, he regards it as historically transcendent in its form, and as consequently playing a crucial role in the transition to the next historical epoch. The discussion begins with Hegel's views on the role of philosophy in history and proceeds to his conception of his place in the history of philosophy. (shrink)

In an essay entitled ‘The Nobility of Sight’, Hans Jonas argues that ‘[s] ince the days of Greek philosophy sight has been recognized as the most excellent of senses’ (Jonas, 1954, p.507). Seeking to account for the historical elevation of vision over other forms of sensory engagement with the world, Jonas contends that ‘[t]he unique distinction of sight consists in what we may call the image performance, where “image” implies three characteristics: (1) simultaneity in the presentation of a manifold; (2) (...) neutralization of the causality of sense-affection; (3) distance in the spatial and mental senses’ (ibid.). In the case of (1), what distinguishes sight from other senses is the fact that it can give us both dynamic and static reality: our eyes can survey a whole field of possible percepts as well as focus directly upon a fixed object (ibid., pp.508–9). In the case of (2), what further marks out vision is that it does not require the perceiver and the object of perception to be directly engaged — the ‘dynamic’ relation between the two is, in Jonas’ words, ‘neutralized’ (ibid., p.514). And in the case of (3), seeing’s inimitability is also guaranteed by its being ‘the only sense in which the advantage lies not in proximity but in distance: the best view is by no means the closest view’ (ibid., pp.517–8).

The System of Ethics was published at the height of Fichte's academic career and marks the culmination of his philosophical development in Jena. Much more than a treatise on ethics narrowly construed, the System of Ethics presents a unified synthesis of Fichte's core philosophical ideas, including the principle I-hood, self-activity and self-consciousness, and also contains his most detailed treatment of action and agency. This volume brings together an international group of leading scholars on Fichte, and is the first of its (...) kind in English to offer critical and interpretive perspectives on this work, covering topics such as normativity, belief, justification, desire, duty, and the ethical life. It will be an essential guide for scholars wanting to deepen their understanding of Fichte's ethical thought, as well as for those interested in the history of ethics more broadly. (shrink)

Weak emergence is the view that a system’s macro properties can be explained by its micro properties but only in an especially complicated way. This paper explains a version of weak emergence based on the notion of explanatory incompressibility and “crawling the causal web.” Then it examines three reasons why weak emergence might be thought to be just in the mind. The first reason is based on contrasting mere epistemological emergence with a form of ontological emergence that involves irreducible downward (...) causation. The second reason is based on the idea that attributions of emergence are always a reflection of our ignorance of non-emergent explanations. The third reason is based on the charge that complex explanations are anthropocentric. Rather than being just in the mind, weak emergence is seen to involve a distinctive kind of complex, macro-pattern in the mind-independent objective micro-causal structure that exists in nature. The paper ends by addressing two further questions. One concerns whether weak emergence applies only or mainly to computer simulations and computational systems. The other concerns the respect in which weak emergence is dynamic rather than static. (shrink)

Weak emergence has been offered as an explication of the ubiquitous notion of emergence used in complexity science (Bedau 1997). After outlining the problem of emergence and comparing weak emergence with the two other main objectivist approaches to emergence, this paper explains a version of weak emergence and illustrates it with cellular automata. Then it explains the sort of downward causation and explanatory autonomy involved in weak emergence.

This paper describes and defends the view that minimal chemical life essentially involves the chemical integration of three chemical functionalities: containment, metabolism, and program (Rasmussen et al. in Protocells: bridging nonliving and living matter, 2009a ). This view is illustrated and explained with the help of CMP and Rasmussen diagrams (Rasmussen et al. In: Rasmussen et al. (eds.) in Protocells: bridging nonliving and living matter, 71–100, 2009b ), both of which represent the key chemical functional dependencies among containment, metabolism, and (...) program. The CMP model of minimal chemical life gains some support from the broad view of life as open-ended evolution, which I have defended elsewhere (Bedau in The philosophy of artificial life, 1996 ; Bedau in Artificial Life, 4:125–140, 1998 ). Further support comes from the natural way the CMP model resolves the puzzle about whether life is a matter of degree. (shrink)

An innocent form of emergence—what I call "weak emergence"—is now a commonplace in a thriving interdisciplinary nexus of scientific activity—sometimes called the "sciences of complexity"—that include connectionist modelling, non-linear dynamics (popularly known as "chaos" theory), and artificial life.1 After defining it, illustrating it in two contexts, and reviewing the available evidence, I conclude that the scientific and philosophical prospects for weak emergence are bright.

The robust behavior of the patent citation network is a complex target of recent bottom-up models in science. This paper investigates the purpose and testing of three especially simple bottom-up models of the citation count distribution observed in the patent citation network. The complex causal webs in the models generate weakly emergent patterns of behavior, and this explains both the need for empirical observation of computer simulations of the models and the epistemic harmlessness of the resulting epistemic opacity.

Artificial life uses computer models to study the essential nature of the characteristic processes of complex adaptive systems proceses such as self-organization, adaptation, and evolution. Work in the field is guided by the working hypothesis that simple computer models can capture the essential nature of these processes. This hypothesis is illustrated by recent results with a simple population of computational agents whose sensorimotor functionality undergo open-ended adaptive evolution. These might illuminate three aspects of complex adaptive systems in general: punctuated equilibrium (...) dynamics of diversity, a transition separating genetic order and disorder, and a law of adaptive evolutionary activity.

The basic bimodal systemK/K can be interpreted as an analysis of the logic of ability developed in [1]. Where in [1] we would express the claimI can bring it about that P using the formula, with its non-normal operator, we will now use the formula. Here is a normal alethic possibilitation operator.is a normal necessitation operator, but it is independent of, and not subject to an alethic interpretation. Rather, is interpreted to meanI bring it about that P. The result is (...) a simplification and clarification of a combined logic of ability and action like that in [2], but employing only normal operators.A number of extensions of the basic systemK/K are constructed, first by strengthening the two normal sublogics independently and then by linking the two sublogics via axiom schemata involving both operators. The result is a series of increasingly strong systems which more and more adequately fulfill our expectations for a satisfactory logic of action and ability. (shrink)

The dynamical patterns in mental phenomena have a characteristic suppleness&emdash;a looseness or softness that persistently resists precise formulation&emdash;which apparently underlies the frame problem of artificial intelligence. This suppleness also undermines contemporary philosophical functionalist attempts to define mental capacities. Living systems display an analogous form of supple dynamics. However, the supple dynamics of living systems have been captured in recent artificial life models, due to the emergent architecture of those models. This suggests that analogous emergent models might be able to explain (...) supple dynamics of mental phenomena. These emergent models of the supple mind, if successful, would refashion the nature of contemporary functionalism in the philosophy of mind. (shrink)

Ligation is a form of chemical self-assembly that involves dynamic formation of strong covalent bonds in the presence of weak associative forces. We study an extremely simple form of ligation by means of a dissipative particle dynamics (DPD) model extended to include the dynamic making and breaking of strong bonds, which we term dynamically bonding dissipative particle dynamics (DDPD). Then we use a chemical genetic algorithm (CGA) to optimize the model’s parameters to achieve a limited form of ligation of trimers—a (...) proof of principle for the evolutionary design of self-assembling chemical systems.

Synthetic biology has spawned a debate about how society and the international community should go about policy‐making, especially given the potential for both transformative benefits and existential threats. One of the significant contributions of “The Ethics of Synthetic Biology: Next Steps and Prior Questions,” by Kaebnick, Gusmano, and Murray, is its exploration of the difficulties of devel­oping policy that appropriately addresses the risks and benefits of synthetic biology. In this comment I want to develop this point further and emphasize how (...) the proper methodology for addressing synthetic biology's ethical and public policy issues are affected by the unpredictable and complex causal webs in synthetic biology (which have analogs in other new and emerging technologies).

The concept of living technology can be applied to any technology that is powerful and useful specifically because it has some of the fundamental features of living systems. This article is a brief general overview of living technology's current state and projected future. After illustrating living technology and discussing why it is complicated to define, I explain how it is related to so-called NBIC convergence (see below) and discuss some of the larger social, ethical and aesthetic issues that it raises.

Normal systems of modal logic, interpreted as deontic logics, are unsuitable for a logic of conflicting obligations. By using modal operators based on a more complex semantics, however, we can provide for conflicting obligations, as in [9], which is formally similar to a fragment of the logic of ability later given in [2], Having gone that far, we may find it desirable to be able to express and consider claims about the comparative strengths, or degrees of urgency, of the conflicting (...) obligations under which we stand. This paper, building on the formalism of the logic of ability in [2], provides a complete and decidable system for such a language. (shrink)

Top-down synthetic biology makes partly synthetic cells by redesigning simple natural forms of life, and bottom-up synthetic biology aims to make fully synthetic cells using only entirely nonliving components. Within synthetic biology the notions of complexity and emergence are quite controversial, but the imprecision of key notions makes the discussion inconclusive. I employ a precise notion of weak emergent property, which is a robust characteristic of the behavior of complex bottom-up causal webs, where a complex causal web is one that (...) is incompressible and its behavior cannot be derived except by crawling through all of the gory details of the interactions in the web. The central thesis of this article is that synthetic biology centrally is the activity of engineering the desired weak emergent properties of synthetic cells. Synthetic biology has many different ways to engineer desired weak emergent properties of synthetic cells, including Edisonian trial and error, standardized parts, refactoring, and reprogramming synthetic genomes. The article ends by noting two philosophical consequences of engineering weak emergence. One is epistemological: synthesis is crucial for discovering weak emergent properties. The other is metaphysical: simple life forms are nothing but complex chemical mechanisms. (shrink)

In the post-genome world of biomedical research, an increasingly common research strategy is to focus on large repositories of biological specimens. There are now several well-known efforts to compile vast collections of biological materials, reanalyze extant samples, collect new ones, and link the samples to medical records. The significant issues of law, ethics, and policy raised by these research activities usually are heightened when commercial enterprises play a leading role in accumulating and distributing the samples. Emerging companies are not only (...) compiling repositories for their own use, but some companies are positioning themselves to act as intermediaries, developing vast biobanks for sale to a wide range of other researchers.

There is a long history of cryptographic hash functions, i.e. functions mapping variable-length strings to fixed-length strings, and such functions are also expected to enjoy certain security properties. Hash functions can be effected via modular arithmetic, permutation-based schemes, chaotic mixing, and so on. Herein we introduce the notion of an artificial-life (ALife) hash function (ALHF), whereby the requisite mixing action of a good hash function is accomplished via ALife rules that give rise to complex evolution of a given system. Various (...) security tests have been run, and the results reported for examples of ALHFs. (shrink)

We demonstrate a method for optimizing desired functionality in real complex chemical systems, using a genetic algorithm. The chemical systems studied here are mixtures of amphiphiles, which spontaneously exhibit a complex variety of self-assembled molecular aggregations, and the property optimized is turbidity. We also experimentally resolve the fitness landscape in some hyper-planes through the space of possible amphiphile formulations, in order to assess the practicality of our optimization method. Our method shows clear and significant progress after testing only 1 % (...) of the possible amphiphile formulations. (shrink)

Abstract:Moral imagination is a reasoning process thought to counter the organizational factors that corrupt ethical judgment. We describe the psychology of moral imagination as composed of the four decision processes identified by Rest (1986), i.e., moral sensitivity, moral judgment, moral intention, and moral behavior. We examine each process in depth, distilling extant psychological research and indicating organizational implications. The conclusion offers suggestions for future research.The majority of men are subjective toward themselves and objective toward all others—terribly objective sometimes—but the real (...) task is in fact to be objective toward one’s self and subjective toward all others.

Evolvability is the capacity to create new adaptations, and especially new kinds of adaptations, through the evolutionary process.
