Our examination explicates not only how Leibniz’s emphasis on force or power squares well with (and most probably largely stems from) his endorsement of certain central Aristotelian tenets, but also how the concept of force is incorporated into his mature idealist metaphysics. That metaphysics, in turn, generates some thorny problems with regard to the concept of passivity; and so we shall also ask whether and how Leibniz’s monadology, emphasizing the activity as much as it does, is able to (...) encompass the passivity of created substances.

Definition of the problem: In order to discuss the normative aspects of euthanasia one has to clarify what is meant by active and passive euthanasia. Arguments and conclusion: Many theoreticians deny the possibility of distinguishing between the two by purely descriptive means, e.g. on the basis of theories of action or the differences between acting and omitting. On the contrary, such a purely descriptive distinction will be defended in this paper by summarizing and refining the theory of Dieter Birnbacher, which (...) he developed in his book Tun und Unterlassen. I will suggest a new definition of active and passive euthanasia. (shrink)

Many philosophers maintain that there is a distinction between acts that the agent plays an active role in producing, and acts that issue from the agent in a more passive fashion. According to the standard account, we can make sense of this distinction by maintaining that reflective or deliberative acts are paradigmatic cases of an agent’s playing an active role in the production of action. This chapter argues that this standard account is mistaken. Reflective or deliberative actions will seem to (...) be active only if we conflate three claims: that choice causes action, that motives do not determine choice, and that reflection suspends the effects of motives. The chapter argues that while and are true, is false. Further, is needed to support the claim that reflective acts are active. Given the falsity of, the chapter shows that reflective acts are not necessarily more active than unreflective ones. The chapter closes by suggesting a new model of agential activity. (shrink)

The view that voluntary active euthanasia and physician-assisted suicide should be made available for terminal patients only is typically warranted by reference to the risks that the procedures are seen to involve. Though they would appear to involve similar risks, the commonly endorsed end-of-life practices referred to as passive euthanasia are available also for non-terminal patients. In this article, I assess whether there is good reason to believe that the risks in question would be bigger in the case of voluntary (...) active euthanasia and physician-assisted suicide than in that of passive euthanasia. I propose that there is not. On that basis, I suggest that limiting access to voluntary active euthanasia and physician-assisted suicide to terminal patients only is not consistent with accepting the existing practices of passive euthanasia.

In the early modern period, many authors held that sensation or sensory reception is in some way passive and that perception is in some way active. The notion of a more passive and a more active aspect of perception is already present in Aristotle: the senses receive forms without matter more or less passively, but the “primary sense” also recognizes the salience of present objects. Ibn al-Haytham distinguished “pure sensation” from other aspects of sense perception, achieved by “discernment, inference and (...) recognition,” which included perception of properties such as size and distance as well as similarity, difference, and beauty. Descartes regarded light and color as experiences passively caused in the mind by bodily processes, but he also included distance, perceived through accommodation and convergence, as an immediately caused sensory idea. On the perception side, most theorists held that size and distance perception occurs through unnoticed psychological operations, whether mediated by judgment or associative processes. Association is, in a sense, passive, as it occurs through nonreflective habit formation. But such habits mark a contribution of the subject to perception and are in that way active. The decision of whether sensation and perception are active or passive is highly sensitive to what counts as activity and to what is included as sensation or perception. There is no simple formula, but the generalization that sensation is for the most part passive and perception for the most part active may stand as an imprecise summary of early modern thought on the topic.

The distinction between active and passive mind has been discussed by recent Augustine scholars, mainly in connection to the question whether - and if so to what extent - the Augustinian mind could be said to be active given the doctrine of divine illumination. The doctrine has prompted some to emphasize the mainly passive nature of the human mind in attaining knowledge, while others have argued that the doctrine should not be so construed as to downplay the role the human (...) mind plays in cognition. Of the latter, some have emphasized the role of the act of judgment, others the mind’s act of discovering within itself the standards of “eternal reasons”, and still others the role of the “created” as well as the “uncreated” light. While framing the discussion of the active and passive mind in this way, does help us clarify Augustine’s epistemological views, and at the same time fails to bring out the specific conception of the “active” mind that Augustine himself had and wished to emphasize. I explain what this conception is, then show that the distinction is put in use in his philosophy with a view that recent commentators have not emphasized in their interpretation of this distinction, as regards the role of the mind’s activity as a condition for non-empirical as well as empirical cognition.

Social media plays a vital role in consumers’ purchasing decision making. There are still gaps in existing research on the relationship between divided dimensions of social media use and impulse buying, as well as the mediating and moderating effects therein. This study explored the mediation and moderation effects in the relationship between different social media usage patterns, emotional responses, and consumer impulse buying. Data from 479 college students who were social media users in China were analyzed using structural equation modeling. (...) The results showed that active and passive social media use were significantly and positively associated with users’ enjoyment, whereas passive social media use significantly increased depression. Both enjoyment and depression were significantly and positively associated with users’ impulse buying. Materialism positively moderated the relationship between enjoyment and impulsive consumption, while self-control significantly reduced the effect of depression on impulse buying. These findings that emotion mediated and personality traits moderated relationships between social media use and impulse buying expand impulsive purchase literature and provide insights for guiding college students’ healthy use of social media and rational consumption.

This paper is divided into three sections. The first presents some examples of the killing/letting die distinction. The second draws a further distinction between what I call negative and positive cases of acting or refraining. Here I argue that the moral significance of the acting/refraining distinction is different for positive and for negative cases. In the third section I apply the above distinction to euthanasia, and argue that mercy killing should be regarded as analogous to positive rather than negative cases. (...) On the basis of this, I then support active rather than passive euthanasia. (shrink)

Newton published his deduction of universal gravity in Principia (first ed., 1687). To establish the universality (the particle-to-particle nature) of gravity, Newton must establish the additivity of mass. I call ‘additivity’ the property a body's quantity of matter has just in case, if gravitational force is proportional to that quantity, the force can be taken to be the sum of forces proportional to each particle's quantity of matter. Newton's argument for additivity is obscure. I analyze and assess manuscript versions of (...) Newton's initial argument within his initial deduction, dating from early 1685. Newton's strategy depends on distinguishing two quantities of matter, which I call ‘active’ and ‘passive’, by how they are measured. These measurement procedures frame conditions on the additivity of each quantity so measured. While Newton has direct evidence for the additivity of passive quantity of matter, he does not for that of the active quantity. Instead, he tries to infer the latter from the former via conceptual analyses of the third law of motion grounded largely on analogies to magnetic attractions. The conditions needed to establish passive additivity frustrate Newton's attempted inference to active additivity. (shrink)

This chapter takes a fresh look at 3d2 of Spinoza’s Ethics, an absolutely pivotal definition for the ethical theory that ensues. According to it, “we act when something happens, in us or outside us, of which we are the adequate cause,” whereas we are passive “when something happens in us, or something follows from our nature, of which we are only a partial cause.” The definition of activity has puzzled scholars: how can we be an adequate, i.e. complete, cause (...) of an effect outside us (which clearly involves other causal factors as well)? However, the definition of passivity is hardly unproblematic either: how can something follow from the patient’s nature so that the patient can nevertheless be considered only a partial cause? I begin by outlining 3d2 and situating it in the historical context formed by Descartes, Hobbes, and the Aristotelian tradition. Then I show that the existing interpretations do not solve the problem of activity and argue that unraveling the problem requires taking properly into account the distinction between immanent and transeunt causality. In relation to the definition of passivity, I argue that Spinoza’s geometry-inspired theory of essence constitution offers the key to understanding the nature of passions. (shrink)

The doctrine of imputation is common to Early Modern Lutheran and Reformed theology, but Reformed orthodox theologians employed the distinction between the active and passive justification of the believer. Active justification is the objective imputation of Christ’s righteousness and passive justification is the subjective reception of the same. This distinction is a unique contribution in Reformed orthodox dogmatics and was used in polemics against Roman Catholic, Arminian, and Socinian theologians. This essay also compares Reformed orthodox formulations with Lutheran orthodox understandings (...) of how they preserved the extra nos of Christ’s righteousness in justification. The Reformed orthodox employed the active-passive justification distinction in conjunction with the decree and the doctrine of the covenant of redemption, whereas the Lutheran orthodox logically placed justification first in the order of salvation. Both groups maintain the extra nos of Christ’s imputed righteousness but do so in different ways. (shrink)

In their account of passive euthanasia, Garrard and Wilkinson present arguments that might lead one to overlook significant moral differences between killing and letting die. To kill is not the same as to let die. Similarly, there are significant differences between active and passive euthanasia. Our moral duties differ with regard to them. We are, in general, obliged to refrain from killing each and everyone. We do not have a similar obligation to try to prevent each and everyone from dying. (...) In any case, to be morally obliged to persist in trying to prevent their deaths would be different from being morally obliged to refrain from killing all other people even if we had both obligations.

Impaired hand proprioception can lead to difficulties in performing fine motor tasks, thereby affecting activities of daily living. The majority of children with unilateral cerebral palsy experience proprioceptive deficits, but accurately quantifying these deficits is challenging due to the lack of sensitive measurement methods. Robot-assisted assessments provide a promising alternative, however, there is a need for solutions that specifically target children and their needs. We propose two novel robotics-based assessments to sensitively evaluate active and passive position sense of the index (...) finger metacarpophalangeal joint in children. We then investigate test-retest reliability and discriminant validity of these assessments in uCP and typically developing children, and further use the robotic platform to gain first insights into fundamentals of hand proprioception. Both robotic assessments were performed in two sessions with 1-h break in between. In the passive position sense assessment, participant's finger is passively moved by the robot to a randomly selected position, and she/he needs to indicate the perceived finger position on a tablet screen located directly above the hand, so that the vision of the hand is blocked. Active position sense is assessed by asking participants to accurately move their finger to a target position shown on the tablet screen, without visual feedback of the finger position. Ten children with uCP and 10 age-matched TDC were recruited in this study. Test-retest reliability in both populations was good >0.79). Proprioceptive error was larger for children with uCP than TDC, indicating discriminant validity. The active position sense was more accurate than passive, and the scores were not correlated, underlining the need for targeted assessments to comprehensively evaluate proprioception. There was a significant effect of age on passive position sense in TDC but not uCP, possibly linked to disturbed development of proprioceptive acuity in uCP. Overall, the proposed robot-assisted assessments are reliable, valid and a promising alternative to commonly used clinical methods, which could help gain a better understanding of proprioceptive impairments in uCP, facilitating the design of novel therapies.

As a new approach to the still unsettled problem of a morally significant difference between active and passive euthanasia, the meanings of the notion of killing are distinguished on the levels of causality, intention, and motivation. This distinction allows a thorough analysis and refutation of arguments for the equality of killing and letting die which are often put forward in the euthanasia debate. Moreover, an investigation into the structure of the physician's action on those three levels yields substantial differences between (...) the two ways of acting. As can be demonstrated, only a teleological notion of the organism is able to grasp the characteristic feature of active euthanasia. On this basis it is argued that an action against the organism as a whole must, on the interpersonal level, be at once directed against the patient as a person himself. (shrink)

How to draw the distinction between activity and passivity? Whatever that might be, the causal theory of action cannot give the right answer, as it offers an essentially passive account of human action.

Many studies show a developmental advantage for transitive sentences with familiar verbs over those with novel verbs. It might be that once familiar verbs become entrenched in particular constructions, they would be more difficult to understand (than would novel verbs) in non-prototypical constructions. We provide support for this hypothesis investigating German children using a forced-choice pointing paradigm with reversed agent-patient roles. We tested active transitive verbs in study 1. The 2-year olds were better with familiar than novel verbs, while the (...) 2½-year olds pointed correctly for both. In study 2, we tested passives: 2½-year olds were significantly below chance for familiar verbs and at chance for novel verbs, supporting the hypothesis that the entrenchment of the familiar verbs in the active transitive voice was interfering with interpreting them in the passive voice construction. The 3½-year olds were also at chance for novel verbs but above chance with familiar verbs. We interpret this as reflecting a lessening of the verb-in-construction entrenchment as the child develops knowledge that particular verbs can occur in a range of constructions. The 4½-year olds were above chance for both familiar and novel verbs. We discuss our findings in terms of the relative entrenchment of lexical and syntactic information and to interference between them. (shrink)

In this article, I review A Theory of Legal Personhood, explaining what I see as its key contributions to animal law scholarship, while situating it against wider jurisprudential contributions that may be of interest to philosophers and legal scholars grappling with the oft-thorny idea of legal personhood, not just for nonhuman animals but for corporations, artificially intelligent machines, and late-term fetuses. The article will explain Kurki's “bundle” theory of legal personhood as a “cluster” concept and analyze the extremely helpful parsing (...) his theory provides in terms of the active and passive “incidents” of legal personhood. I focus much of the piece on Kurki's view of legal “nonpersons” who nonetheless have some rights or incidents of personhood in order to help clarify the challenge Kurki's theory raises for Steven M. Wise and the Nonhuman Rights Project, as the issues surrounding those litigation efforts will likely be familiar to readers here, who will be wondering how this theory interacts with what Wise seeks to achieve.

Many powers metaphysicians postulate both active and passive powers, understood as distinct kinds of intrinsic causal properties of objects. I argue that the category of passive power is superfluous. I also offer a diagnosis of how philosophers are misled to postulate passive powers.
