It is widely accepted that stressful conditions can facilitate evolutionary change. The mechanisms elucidated thus far accomplish this with a generic increase in heritable variation that facilitates more rapid adaptive evolution, often via plastic modifications of existing characters. Through scrutiny of different meanings of stress in biological research, and an explicit recognition that stressors must be characterized relative to their effect on capacities for maintaining functional integrity, we distinguish between: (1) previously identified stress-responsive mechanisms that facilitate evolution by maintaining an (...) adaptive fit with the environment, and (2) the co-option of stress-responsive mechanisms that are specific to stressors leading to the origin of novelties via compensation. Unlike standard accounts of gene co-option that identify component sources of evolutionary change, our model documents the cost-benefit trade-offs and thereby explains how one mechanism—an immediate response to acute stress—is transformed evolutionarily into another—routine protection from recurring stressors. We illustrate our argument with examples from cell type origination as well as processes and structures at higher levels of organization. These examples suggest a general principle of evolutionary origination based on the capacity to switch between regulatory states related to reproduction and proliferation versus survival and differentiation.

The origin of marine invertebrate larvae has been an area of controversy in developmental evolution for over a century. Here, we address the question of whether a pelagic “larval” or benthic “adult” morphology originated first in metazoan lineages by testing the hypothesis that particular gene co-option patterns will be associated with the origin of feeding, indirect developing larval forms. Empirical evidence bearing on this hypothesis is derivable from gene expression studies of the sea urchin larval gut of two closely related (...) but differently developing congenerics, Heliocidaris tuberculata (feeding indirect-developing larva) and H. erythrogramma (nonfeeding direct developer), given two subsidiary hypotheses. (1) If larval gut gene expression in H. tuberculata was co-opted from an ancestral adult expression pattern, then the gut expression pattern will remain in adult H. erythrogramma despite its direct development. (2) Genes expressed in the larval gut of H. tuberculata will not have a coordinated expression pattern in H. erythrogramma larvae due to loss of a functional gut. Five structural genes expressed in the invaginating archenteron of H. tuberculata during gastrulation exhibit substantially different expression patterns in H. erythrogramma with only one remaining endoderm specific. Expression of these genes in the adult of H. erythrogramma and larval gut of H. tuberculata, but not in H. erythrogramma larval endoderm, supports the hypothesis that they first played roles in the formation of adult structures and were subsequently recruited into larval ontogeny during the origin and evolution of feeding planktotrophic deuterostome larvae.

Options and the subjective ought Content Type Journal Article Pages 1-18 DOI 10.1007/s11098-012-9880-0 Authors Brian Hedden, Department of Linguistics and Philosophy, Massachusetts Institute of Technology, Cambridge, MA, USA Journal Philosophical Studies Online ISSN 1573-0883 Print ISSN 0031-8116.

Brian Hedden has proposed that any successful account of options for the subjective “ought” must satisfy two constraints: first, it must ensure that we are able to carry out each of the options available to us, and second, it should guarantee that the set of options available to us supervenes on our mental states. In this paper I show that, due to the ever-present possibility of Frankfurt-style cases, these two constraints jointly entail that no agent has any options at any (...) time. This consequence, however, is clearly unacceptable, so one of Hedden’s constraints must go. Because the ability constraint is indispensable, I argue, we have no choice but to reject the supervenience constraint. Hedden’s underlying motivation for imposing the supervenience constraint is the conviction that our options should be transparent to us, but transparency also proves to be incompatible with the ability constraint, so it must be rejected as well. I conclude by sketching an unabashedly externalist account of options, which conceives of options as exhaustive combinations of atomic movements. (shrink)

Many of us think we have agent-centred options to act suboptimally. Some of these involve favouring our own interests. Others involve sacrificing them. In this paper, I explore three different ways to accommodate agent-centred options in a criterion of objective permissibility. I argue against satisficing and rational pluralism, and in favour of a principle built around sensitivity to personal cost.

Autonomous e-coaching systems offer their users suggestions for action, thereby affecting the user's decision-making process. More specifically, the suggestions that these systems make influence the options for action that people actually consider. Surprisingly though, options and the corresponding process of option generation --- a decision-making stage preceding intention formation and action selection --- has received very little attention in the various disciplines studying decision making. We argue that this neglect is unjustified and that it is important, particularly for designers of (...) autonomous e-coaching systems, to understand how human option generation works. The aims of this paper are threefold. The first aim is to generate awareness with designers of autonomous e-coaching systems that these systems do in fact influence their users' options. The second is to show that understanding the interplay between a person's options and the e-coaching system's suggestions is important for improving the effectiveness of the system. The third is that the very same interplay is also crucial for designing e-coaching systems that respect people's autonomy. (shrink)

The recent debates about the nature of social freedom, understood in a broadly negative way, have generated three main views of the topic: these represent freedom respectively as non-limitation, non-interference and non-domination. The participants in these debates often go different ways, however, because they address different topics under common names, not because they hold different intuitions on common topics. Social freedom is sometimes understood as option-freedom, sometimes as agency-freedom and the different directions taken by the theories can often be explained (...) by their addressing freedom in one sense, then in another. The non-limitation approach focuses primarily on option-freedom, the non-domination approach on agencyfreedom, whereas the representation of freedom as non-interference seems to spring from a failure to resolve the focus decisively on one target or another.

We ought to perform our best option—that is, the option that we have most reason, all things considered, to perform. This is perhaps the most fundamental and least controversial of all normative principles concerning action. Yet, it is not, I believe, well understood. For even setting aside questions about what our options are and what our reasons are, there are prior questions concerning how best to formulate the principle. In this paper, I address these questions. One of the more interesting (...) upshots of this inquiry is that the deontic statuses (e.g., obligatory, optional, and impermissible) of individual actions are determined by the deontic statuses of the larger sets of actions of which they are a part. And, as I show, this has a number of interesting implications both for normative theory and for our understanding of practical reasons. (shrink)

The concept of ecosystem services is a way of visualizing the instrumental value that nature has for human beings. Most ecosystem services can be performed by more than one species. This fact is sometimes used as an argument against the preservation of species. However, even though substitutability does detract from the instrumental value of a species, it also adds option value to it. The option value cannot make a substitutable species as instrumentally valuable as a non-substitutable species, but in many (...) cases, it can add enough value to make the species more valuable than the projects that threaten its existence.

Many endorse the Bad-Difference View of disability which says that disability makes one likely to be worse off even in the absence of discrimination against the disabled. Others defend the Mere-Difference View of disability which says that, discounting discrimination, disability does not make one likely to be worse off. A common motivation for the BDV is the Options Argument which identifies reduction in valuable options as a harm of disability. Some reject this argument, arguing that disabled people's prospects aren't hindered (...) by having fewer options. In this article, I defend the Options Argument by arguing that, in disability cases, possessing a greater number of valuable options seems to overall improve well-being prospects. As such, the Options Argument appears to be sound and – although it doesn't establish the BDV – it lends plausibility to the BDV by identifying a potentially significant cost of disability. (shrink)

Logical Options introduces the extensions and alternatives to classical logic which are most discussed in the philosophical literature: many-sorted logic, second-order logic, modal logics, intuitionistic logic, three-valued logic, fuzzy logic, and free logic. Each logic is introduced with a brief description of some aspect of its philosophical significance, and wherever possible semantic and proof methods are employed to facilitate comparison of the various systems. The book is designed to be useful for philosophy students and professional philosophers who have learned some (...) classical first-order logic and would like to learn about other logics important to their philosophical work.

Altruistic punishment has been shown to invade when rare if individuals are allowed to opt out of cooperative ventures. Individuals that opt out do not contribute to the common enterprise or derive benefits from it. This result is potentially significant because it offers an explanation for the origin of large-scale cooperation in oneshot interactions among unrelated individuals. Here, we show that this result is not a general consequence of optional participation in cooperative activities, but depends on special assumptions about cooperative (...) pay-offs. We extend the pay-off structure of optional participation models to consider the effects of economies and diseconomies of scale in public-goods production, rival and non-rival consumption of goods, and different orderings of the pay-offs of freeriding and opting out. This more general model highlights the kinds of pay-offs for which optional participation favours cooperation, and those in which it does not. (shrink)

The Bush administration was widely praised for having shifted to a more conciliatory stand -- namely, by allowing a US diplomat to attend without participating -- while Iran was castigated for failing to negotiate seriously. And the powers warned Iran that it would soon face more severe sanctions unless it terminated its uranium enrichment programs.

In this commentary I take up thoughts about the sociology of time and Luhmann’s theory to consider whether automated future option maximization can be extended with a social dimension.

A prominent defence of a market in organs from living donors says that if we truly care about people in poverty, we should allow them to sell their organs. The argument is that if poor vendors would have voluntarily decided to sell their organs in a free market, then prohibiting them from selling makes them even worse off, at least from their own perspective, and that it would be unconscionably paternalistic to substitute our judgements for individuals' own judgements about what (...) would be best for them. The author shows that this ‘Laissez-Choisir Argument’ for organ selling rests on a mistake. This is because the claim that it would be better for people in poverty to sell their organs if given the option is consistent with the claim that it would be even better for them to not have the option at all. The upshot is that objections to an organ market need not be at all paternalistic, since we need not accept that the absence of a market makes those in poverty any worse off, even from their own point of view. The author goes on to argue that there are strong theoretical and empirical reasons for believing that people in poverty would in fact be harmed by the introduction of a market for live donor organs and that the harm constitutes sufficient grounds for prohibiting a market.

_The Liberty Option_ advances the idea that for compelling moral as well as practical reasons it is the free society -- with the rule of law founded on the principles of private property rights, its complete respect for individual sovereignty and properly limited legal authorities -- not one or another version of statism that serves justice best, is most prosperous and encourages the greatest measure of individual virtue on the part of the citizenry. The work shows why this is so (...) and lays out some of the most crucial implications of the idea. While the book presents a principled approach to politics, it is firmly grounded in the best and most up to date understanding of human community life and history as well as many of its complications, challenges, adversities and prospects.

Real-life decision-making often begins with a disorderly decision problem that has to be clarified and systematized before a decision can be made. This is the process of decision structuring that has largely been ignored both in decision theory and applied decision analysis. In this contribution, ten major components of decision structuring are identified, namely the determination of its scope, subdivision, agency, timing, options, control ascriptions, framing, horizon, criteria and restructuring. Four of these components, namely the scope, subdivision, options, and horizon (...) of a decision, are subjected to a more detailed analysis. (shrink)

Moral options are permissions to do less than best, impartially speaking. In this paper, we investigate the challenge of reconciling moral options with the ideal of justifiability to each individual. We examine ex-post and ex-ante views of moral options and show how they might conflict with this ideal in single-choice and sequential-choice cases, respectively. We consider some ways of avoiding this conflict in sequential-choice cases, showing that they face significant problems.

A familiar part of debates about supererogatory actions concerns the role that cost should play. Two camps have emerged: one claiming that extreme cost is a necessary condition for when an action is supererogatory, while the other denies that it should be part of our definition of supererogation. In this paper, I propose an alternative position. I argue that it is comparative cost that is central to the supererogatory and that it is needed to explain a feature that all accounts (...) agree is central to the very notion of supererogation: optionality. Perhaps because of this agreement on its importance, few attempts have been made to clarify and explain the notion of optionality. I argue that giving an account of the optionality of supererogatory requires drawing a line between doing the bare minimum permissible and going beyond the bare minimum and that this line ought to be drawn based on comparative cost of alternative permissible acts. Having outlined my account and motivated it, I discuss and reject two concerns that might be raised: firstly, that it is extreme cost, not comparative cost, that matters and, secondly, that in fact no cost is needed for an act to be supererogatory.

Objective To determine whether presenting delivery room management options as defaults influences decisions to resuscitate extremely premature infants. Materials and methods Adult volunteers recruited from the world wide web were randomised to receive either resuscitation or comfort care as the delivery room management default option for a hypothetical delivery of a 23-week gestation infant. Participants were required to check a box to opt out of the default. The primary outcome measure was the proportion of respondents electing resuscitation. Data were analysed (...) using χ2 tests and multivariate logistic regression. Results Participants who were told the delivery room management default option was resuscitation were more likely to opt for resuscitation (OR 6.54 95% CI 3.85 to 11.11, p<0.001). This effect persisted on multivariate regression analysis (OR 7.00, 95% CI 3.97 to 12.36, p<0.001). Female gender, being married or in a committed relationship, being highly religious, experiences with prematurity, and favouring sanctity of life were significantly associated with decisions to resuscitate. Discussion Presenting delivery room options for extremely premature infants as defaults exert a significant effect on decision makers. The information structure of the choice task may act as a subtle form of manipulation. Further, this effect may operate in ways that a decision maker is not aware of and this raises questions of patient autonomy. Conclusion Presenting delivery room options for extremely premature infants as defaults may compromise autonomous decision-making. (shrink)

An option range is a set of alternative actions available to an agent at a given time. I ask how a moral theory’s account of option ranges relates to its recommendations about deliberative procedure (DP) and criterion of rightness (CR). I apply this question to Act Consequentialism (AC), which tells us, at any time, to perform the action with the best consequences in our option range then. If anyone can employ this command as a DP, or assess (direct or indirect) (...) compliance with it as a CR, someone must be able to tell which actions fit this description. Since the denseness of possibilia entails that any option range is indefinitely large, no one can do this. So no one can know that any option has ever emerged from any range as the best option in that range. However we come to know that a given option is right, we never come to know it in AC’s way. It is often observed that AC cannot give us a DP. AC cannot give us a CR either, unless we are omniscient. So Act Consequentialism is useless. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"An Option for Art But Not an Option for Life":Beauty as an Educational ImperativeJoe Winston (bio)IntroductionIn a recent meeting of the academic staff in the university department where I work, we were asked to state our current research interests. Responses progressed around the circle and everyone listened quietly and respectfully until I stated that my interest was beauty, to which there was general laughter—complicit, not derisory, as if everyone (...) laughing presumed it was a joke. In the same week, I heard a story from a colleague who works in another institution. She had been interviewing a prospective female candidate for their postgraduate teacher training course with a deputy principal from a local school. When it came to a decision, the latter had not been in favor of offering the young woman a place; she was "too beautiful," she thought, to the extent that she would "be a distraction" in the classroom.I offer these stories as illustrative of a fact little discussed—that beauty is a problem in educational discourse, seen as either wildly irrelevant or discordant with the job of teaching. Yet it was not always the case. Beauty has in the past been understood as one of the highest aims of education. For Schiller, it fulfilled a core human need, and he wrote in the second of his Letters on the Aesthetic Education of Man that "it is only through Beauty that man makes his way to Freedom."1 Matthew Arnold argued that it was in beauty that the "human race finds its ideal."2 Emerson saw beauty as "the form under which the intellect likes to study the world,"3 and Iris Murdoch argued that it should be at the base of any education in the virtues, citing Plato's argument that beauty is the one spiritual quality that we love by instinct.4 These figures could hardly be described as philosophical lightweights, yet their sentiments and the complex arguments through which they expressed [End Page 71] them have for years been neglected; only recently has this begun to change. Elaine Scarry, in particular, has written an influential book on the topic, taking up the argument of Iris Murdoch and developing a strong case for the educational power of beauty, allying it strikingly with an education in social justice.5 Two recent articles in this journal have also heralded a re-evaluation of beauty as a concept of profound significance for both the arts and education. Stuart Richmond sees in the development of our capacities to create and appreciate beauty "a way to bring us back into contact with what is sensual and intrinsically worthwhile,"6 and Howard Cannatella argues passionately "that something of the indelible quality of poiesis and delight in beauty should be the focus of specific educational concern, a factor at its core."7This article is an attempt to add further substance to the claim that-beauty should be one of our core educational values. In doing so, it develops the ideas that connect these perspectives: that beauty's power is instinctive, that it delights, that it is of deep human value. As do Murdoch and Scarry in their different ways, I will argue that beauty is powerfully formative and intrinsically associated with virtue, an idea developed in the final section of the article. First, however, I wish to consider what happened to beauty and why it became a neglected concept not only in education but also in the arts.What Happened to Beauty?Language and world refer to each other and presuppose each other for their mutual intelligibility. In this count, human learning becomes the process of aligning language and world.8In considering beauty, we begin inevitably with the word itself and with its usage. Like all evaluative concepts captured through language, beauty is a historical and cultural entity and, as such, it has both gathered and discarded meanings with the passage of time. Consequently, its nature is elusive and open to revision and debate. Is it characterized by perfect harmony and balance, as the classical world would have it, or by the soaring solidity of a medieval Gothic cathedral? Do we associate it with goodness... (shrink)

Recent scandals at Enron, WorldCom and Global Crossing have put the ethical spotlight on corporate malfeasance as never before. However, these are the situations in which management knew that they made the wrong choice. As professor Joseph Badaracco of Harvard Business School points out, the real ethical dilemmas arise when people must choose between right and right — where both choices can be justified, yet one must be chosen over the other. Whether or not to reprice stock options represents one (...) such ethical dilemma. Repricing can help exodus of talented employees and motivate them to improve firm performance. However, it alienates shareholders and other workers of the company who are left unprotected from the adverse economic consequences of a stock price decline.In this paper we examine the ethics and the economics of stock option repricing. We find that repricing runs counter to two key tenets of business ethics — distributive justice and ordinary decency. To examine the economics of repricing, we draw upon agency theory to identify situations where repricing has the potential to benefit shareholders. However, a survey of empirical research reveals that these benefits do not translate into reality. Repricing does not improve employee retention or firm performance. In addition, managers benefit by opportunistically timing the repricing. Due to weaknesses in corporate governance such as lack of independence and conflicts of interest, the current repricing practice seems to be at odds with the objective of shareholder wealth maximization, and at a more fundamental level, a violation of board's fiduciary duty to shareholders. We offer suggestions that mitigate the ethically undesirable effects of repricing in the wider context of prevailing corporate governance and regulatory environment. We believe that these suggestions, if properly implemented, can transform repricing from a greed-inspired evil to a valuable compensation tool to retain employees, boost their morale, and enhance stockholder wealth.

In this paper, I describe a hitherto overlooked kind of practical irrationality, which I call irrational option exclusion. An agent who suffers from this problem does not merely fail to act on her best judgement – she fails to realize that the superior action is even an option for her. I furthermore argue that this kind of irrationality is serious enough to undermine moral responsibility. I show that an agent suffering from this problem has compromised reasons-responsiveness, does not really express (...) her will through action, and has a hard time doing otherwise; thus, from the standpoint of several popular moral responsibility theories, we ought to conclude that her responsibility is at the very least diminished.

Supererogatory acts are those that lie “beyond the call of duty.” There are two standard ways to define this idea more precisely. Although the definitions are often seen as equivalent, I argue that they can diverge when options are infinite, or when there are cycles of better options; moreover, each definition is acceptable in only one case. I consider two ways out of this dilemma.

The relationship of corporate social responsibility to risk management has been treated sporadically in the business society literature. Using real options theory, I develop the notion of corporate social responsibility as a real option its implications for risk management. Real options theory allows for a strategic view of corporate social responsibility. Specifically, real options theory suggests that corporate social responsibility should be negatively related to the firm’s ex ante downside business risk.

As standardly understood, for an act to be optional is for it to be permissible but not required. Supererogatory acts are commonly taken to be optional in this way. In “Supererogation, Optionality and Cost”, Claire Benn rejects this common view: she argues that optionality so understood—permissible but not required—cannot be the sort of optionality involved in supererogation. As an alternative, she offers a novel account of the optionality of supererogatory acts: the “comparative cost” account. In this (...) paper, we rebut Benn’s objection to the common view that supererogation involves optionality as standardly understood. We also point out that her objection, if it worked, would equally undermine her own comparative cost proposal. (shrink)

This paper examines the implications for sustainability policy of environmental uncertainty and indeterminacy, and relates the associated problems with a conventional understanding of sustainable development to Hayek's critique of collective planning.

The argument is illustrated by a practical application: the analysis of natural capital explored in this Special Issue is (...) shown to be directly relevant to the improvement of the UK's headline sustainability indicators package.

This paper argues that people can deserve the option to give. Discussions of desert tend to focus on the benefits and burdens that people might, in some sense, receive, like wealth and jobs. But intuitively, people can also deserve the ability to decide what to do with their wealth or to select who gets a job. Shaping distributive policies and outcomes in accordance with desert is more complicated than philosophers have realised.

The Post-Vatican revision of moral theology aimed to reduce legalism and take better account of the subjective factors in moral decision. Karl Rahner contributed to this effort by his “formal existential ethics” which featured a replacement of the classical “ultimate end” by the concept of the “fundamental ultimate option” as an exercise of transcendental freedom through concrete categorical acts. Diverse interpretations of this principle resulted in the system of “proportionalism” and the thesis of a category of “serious” sins intermediate between (...) mortal and venial has been rejected in Veritatis splendor. Rahner himself seems to have held neither of these positions. The wide acceptance of the “fundamental option” (often with little acquaintance with its philosophical basis) is probably due to its supposed pastoral advantages. I argue that a proper application of the classical notions of ultimate end and the distinction between objective and subjective morality are pastorally more practical and avoids the many philosophical obscurities connected with the idealism of transcendental Thomism.

'Moral luck' refers to the phenomenon whereby one's degree of blameworthiness for what one has done varies on account of factors beyond one's control. Applying concepts of Dworkin's from the domain of distributive justice, I draw a distinction between 'option moral luck,' which is that to which one has exposed oneself as the result of one's voluntary choices, and 'brute moral luck,' which is that which is unchosen and unavoidable. I argue that option moral luck is not ruled out on (...) grounds of unfairness. I also offer a non-fairness-based rejection of brute moral luck and defense of option moral luck. (shrink)
