The desire-satisfaction theory of welfare says that what is basically good for a subject is the satisfaction of his desires. One challenge to this view is the existence of quirky desires, such as a desire to count blades of grass. It is hard to see why anyone would desire such things, and thus hard to believe that the satisfaction of such desires could be basically good for anyone. This suggests that only some desires are basically good when satisfied, and that (...) desire satisfactionists owe us an account of which desires these are, and why. In "Quirky Desires and Well-Being," Donald Bruckner proposes such an account: a desire is welfare-relevant (i.e., such that its satisfaction would be basically good for its subject) if and only if and because its subject could describe its object in a way that makes it comprehensible what about the object attracts him or appeals to him. We are inclined to view quirky desires as welfare-irrelevant because we assume that their objects cannot be described in such a way. But if there were a quirky desire whose object could be so described by the subject whose desire it is, then this desire would be relevant to that subject's welfare. I will argue that while Bruckner's view delivers plausible verdicts about the cases to which it is meant to apply, its account of what makes a desire welfare-relevant is unmotivated and implausible. Desire satisfactionists can retain what is plausible about his view while endorsing a better explanation of why welfare-relevant desires have that status if they accept the following account instead: a desire is welfare-relevant if and only if and because something about its object attracts, or appeals to, the subject who has the desire.

In this chapter, we examine the key moral issues for the intelligence community with regard to the use of robots for intelligence collection. First, we survey the diverse range of spy robots that currently exist or are emerging, and examine their value for national security. This includes describing a number of plausible scenarios in which they have been (or could be) used, including: surveillance, attack, sentry, information collection, delivery, extraction, detention, interrogation and as Trojan horses. Second, we examine several areas (...) in which spy robots present serious ethical and legal challenges. We conclude by examining some moral concerns with shifting from intelligence collection to action, as enabled by robotics technology. (shrink)

In ‘Equity and Marxist Buddhism,’ Tzu-wei Hung engages with the Marxist Buddhism developed by Taiwanese philosopher Lin Qiu-wu in the 1920s, brings this underexplored theory to the table and discusses a few merits and insights of the theory. Building on Hung’s analysis, this paper paper elaborates on the lessons and insights that Taiwanese Marxist Buddhism provides for modern times. The first three lessons are distinctive points that Taiwanese Marxist Buddhism brings to the discussion on combining Marxism and Buddhism: the connections (...) between the ethical and political, the responsibility for pursuing social justice and the nonviolence means towards social justice. The last lesson comes at the meta-philosophical level, focusing on how Hung’s engagement with Taiwanese Marxist Buddhism sheds light on the issue of diversifying the discipline philosophy. Overall, I argue that Taiwanese Marxist Buddhism not only makes contributions to theoretical frameworks while providing a practical means for pursuing equity and social justice, but it also manifests the epistemic and moral values for engaging with under-represented philosophical traditions.

: Perhaps the central problem which preoccupies Spinoza as a moral philosopher is the conflict between reason and passion. He belongs to a long tradition that sees the key to happiness and virtue as mastery and control by reason over the passions. This mastery, however, is hard won, as the passions often overwhelm its power and subvert its rule. When reason succumbs to passion, we act against our better judgment. Such action is often termed 'akratic'. Many commentators have complained that (...) the psychological principles that Spinoza appeals to in his account of akrasia are mere ad hoc modifications to his philosophical psychology. I show, on the contrary, that these principles follow from some of the most important and interesting aspects of Spinoza's philosophy of mind. (shrink)

Although the idea that sexual violence is a “structural” problem is not new, the lack of specification as to what that entails blocks effective responses to it. This paper illustrates the concept of sexual violence as structural in the sense of containing a type of moral wrong called “structural wrong” and discusses its practical implications. First, I introduce a distinction between two types of moral wrongs—interactional wrongs and structural wrongs—and I argue that the moral problem of sexual violence includes both (...) types, each of which calls for a different set of moral responses. Second, drawing on Iris Marion Young’s social connection model of responsibility, I argue that recognizing the structural-wrong element of sexual violence does not reduce individual perpetrators’ responsibility for it. Instead, it implies that a broader group of agents are required to join collective actions to reform the social structure. I conclude by evaluating some preventive programs against sexual violence through the lens of structural wrongs and providing directions to advance them. (shrink)

Can the idea of a minimal proposition be successfully held? I will first formulate what the minimal proposition is in the minimalist’s mind, taking Emma Borg as the representative. What a minimalist seeks for a minimal proposition is the abstract and skeletal core meaning of a sentence, and this faith is founded on the notion of minimal word meaning—an atomic, code-like, conceptual thing. I show that the problem of this notion of minimal proposition lies in the three features, intuitive read-off, (...) invariantness, and truth-evaluability, that Borg ascribes to it. I shall argue, first, that positing a conceptual-like thing as the invariant minimal content of word cannot support the invariantness of the minimal proposition of a sentence, and second, that the skeletal content, as the minimal proposition of a sentence, is a grammatically analyzed product and thus is hardly truth evaluable. According to the analyses, the idea of a minimal proposition with these three features identified by minimalists cannot be maintained. (shrink)

In “Confucianism and Same-Sex Marriage,” published recently in Politics and Religion, Professor Tongdong Bai argues for a “moderate Confucian position on same-sex marriage,” one that supports its legalization and yet endeavors “to use public opinion and social and political policies to encourage heterosexual marriages, and to prevent same-sex marriages from becoming the majority form of marriages” (Bai 2021:146). Against the backdrop of downright homophobia prevalent among vocal Confucians in mainland China today, Bai claims that his pro-legalization rendition “show[s] a different (...) version of Confucianism that challenges the received perception of Confucianism that it is deeply conservative, a perception that often lies at the core of the rejection of its contemporary relevance, especially by the so-called ‘liberals’ in China and elsewhere” (Bai 2021:133). Furthermore, Bai claims that his moderate Confucianism is normatively preferrable to “the typical liberal or individualist position” of a marriage equality supporter, because the specter of polygamy – the conservative trope of invoking polygamy as a reductio ad absurdum against same-sex marriage – imposes “a serious challenge” to liberals but not to moderate Confucians (Bai 2021:146, 153). -/- Both of Bai’s claims falter upon scrutiny, however. Granted, it is applaudable that Bai tries to dissuade his more conservative Confucian colleagues from opposing the legalization of same-sex marriage. But as Section 1 of this Response will show, the alternative rendition of Confucianism he presents, along with the way he presents it, is premised on a highly contested conception of what shared Confucian values are; does injustice to Confucians who embrace marriage equality more unreservedly (i.e., without caveats à la Bai); fails to produce new arguments that “enrich the theoretical basis for same-sex marriage” (Bai 2021:133); and, ironically, reinforces – rather than “challenges” – the “received perception” of Confucianism as deeply conservative. Meanwhile, Section 2 will show that Bai’s comparison between liberalism and moderate Confucianism relies both upon an apparent unfamiliarity with the extensive and nuanced liberal discussions on polygamy, and upon fallacious methods of assessing comparative normative valence. -/- Finally, Section 3 will offer some concluding thoughts from the perspective of decolonial theory, examining the dynamic of spectacularized postcoloniality that propels the production and consumption of dubious theoretical projects like Bai’s. As it turns out, this case serves not only as a cautionary tale of how not to conduct comparative normative theorizing, but also as a cautionary tale of how not to let the spectacle of postcoloniality derail the pursuit of academic decolonization.

Structural injustice exists when the influence of social structure exposes some groups of people to undeserved burdens while conferring unearned power to others. It has been argued that the responsibility for addressing structural injustices should be shared among those participating in the social structure and can only be discharged through collective action; however, the proper form of collective action does not happen easily. To address structural injustice effectively, we need to gain clarity on the practical challenges that are involved and (...) explore possible means of implementing shared responsibility. This chapter thus aims to contribute to the study of addressing structural injustice in the following two ways. First, building on previous studies, I categorize three forms of practical challenges that have been encountered by existing proposals for discharging shared responsibility for structural injustice. Second, I offer an alternative proposal, which I will refer to as the deliberative mini-public proposal, and argue that it has the potential to mobilize structural change and better overcome the identified practical challenges.

In this paper, I respond to criticisms of my book Being and Reason recently made by Yitzhak Melamed.

This paper calls for a paradigm shift in studying academic dependency, towards the paradigm of brokered dependency. Using Chinese academia as an example, I demonstrate how the neocolonial condition of academic dependency is always mediated through blockage-brokerage mechanisms. The two most salient blockage-brokerage mechanisms of dependency in the Chinese context are linguistic barrier and authoritarian malepistemization, and the effects of the latter consist of three layers: institutional, informational and incorporational. On top of their domestic impacts, those mechanisms jointly exacerbate spectacularized (...) postcoloniality in anglophone-hegemonic global academic publishing. The paradigm of brokered dependency not only represents a more nuanced approach to the study of academic dependency, but also underscores the fact that the dismantling of the neocolonial condition cannot be conceived and pursued in isolation from comprehending and confronting the authoritarian condition, especially when the latter pertains under the disguise of anticolonialism.

This paper attempts to revive interest in the speech act theory of literature by looking into Monroe C. Beardsley's account in particular. Beardsley's view in this respect has received, surprisingly, less attention than deserved. I first offer a reconstruction of Beardsley's account and then use it to correct some notable misconceptions. Next, I show that the reformulation reveals a hitherto unnoticed discrepancy in Beardsley's position and that this can be explained away by a weak version of intentionalism that Beardsley himself (...) actually tolerates. Finally, I assess the real difficulty of Beardsley's theory and its relevance today. (shrink)

With the naturalist worldview having become widely accepted, the trend of naturalistic Buddhism has likewise become popular in both academic and religious circles. In this article, I preliminarily reflect on this naturalized approach to Buddhism in two main sections. In section 1, I point out that the Buddha rejects theistic beliefs that claim absolute power over our destiny, opting instead to encourage us to inquire intellectually and behave morally. The distinguishing characteristics of naturalism such as a humanistic approach, rational enquiry, (...) empirical observation, as well as a pragmatic and realistic outlook can all be seen in the Buddha’s teachings. In section 2, however, I advance arguments to show that while the Buddha is opposed to theistic doctrines, his views are not entirely in accordance with the presuppositions of naturalism. Firstly, the Buddha’s foremost concern is not purely intellectual in nature—the purpose of his teachings is to realize a soteriological goal through spiritual practice. Secondly, naturalism tends to subscribe to ‘self-being,’ while the Buddha holds all things to exist conditionally and impermanently. Because of the dependent nature of all things, it is not possible to discover their essence through reduction. Thirdly, naturalized philosophy would be a kind of belief-habit that follows from certain preconditioned assumptions. But the Buddha encourages us to re-examine our conceptual proliferation leading to biased views, as that ultimately leads to suffering. I conclude by proposing a broader naturalist outlook that would allow for a more inclusive conception of the natural world that would take the axiological dimension of human transcendence into account and increase an overall understanding of human potentiality.

Gilbert Ryle’s The Concept of Mind (1949/2002. Chicago, IL: University of Chicago Press) is generally considered a landmark in the quest to refute Cartesian dualism. The work contains many inspirational ideas and mainly posits behavioral disposition as the referent of mind in order to refute mind–body dualism. In this article, I show that the Buddhist theory of ‘non-self’ is also at odds with the belief that a substantial soul exists distinct from the physical body and further point out similarities between (...) the Buddhist outlook and Ryle’s ideas in three parts. First, I illustrate that Ryle’s ‘category mistake’ has certain points in common with the Buddhist refutation of ‘self’. Within the Buddhist framework, referents such as ‘mind’ and ‘self’ are merely imputed terms. The presumed existence of an independent substance such as a ‘soul’, when considered in isolation from the expedient usage of the term ‘mind’, can therefore also be viewed as a ‘category mistake’. Second, attempting to solve the questions of ‘what mind is’ and ‘how mind operates’ are two entirely different approaches to the study of mind. I argue that it is necessary to focus on ‘knowing-how’ rather than ‘knowing-that’, if we are to gain a more comprehensive understanding of mind and avoid any kind of category mistake such as those that follow from isolating the physical properties of brain or drawing inferences from a mystical soul. Third, I aim to show why investigating mind from the perspective of ‘dispositions’ of behavior is a valid approach. The Buddhist concept of karma-vāsanā elucidates the habitual tendency to act or not act in various situations. Based on this theory, I argue that the workings of the human mind bears strong links to the formation of karma and as such have important axiological implications that cannot be ignored. I conclude by pointing out that Ryle’s insightful ideas could in certain ways be complemented by the Buddhist theory of mind. In my view, his philosophy is not only a mediator between Analytic Philosophy and Phenomenology, but could perhaps also be seen as a mediator between traditional Eastern systems of thought and contemporary philosophies of mind.

Emotion is an important issue in Wittgenstein’s philosophy of psychology, yet the literature on this topic is quite small. Wittgenstein’s philosophical investigation is a grammatical one, and he tries to dissolve philosophical problems by using many philosophical methods. In this paper I examine the grammatical rules for some emotion words and the methods he employs in dealing with the philosophical problem of emotion. To facilitate this examination, I first analyze Wittgenstein’s treatment of the problem of sudden understanding, where the grammar (...) and methods are easier to comprehend. I will then show that the grammar and methods used by Wittgenstein in the cases of sudden understanding and emotion are rather similar. (shrink)

Forgiveness is mostly seen as a virtuous human response to wrongful conduct. But what happens when there is no acknowledgement of wrongdoing on the part of the wrongdoer? Does the forgiveness of the unrepentant still count as forgiveness? The Fourteenth Dalai Lama, for instance, is a figure who highly promotes the value of forgiveness. His homeland has been occupied by China since 1950, yet he maintains that he forgives and feels no enmity towards the Chinese government. The Chinese authorities, for (...) their part, have never admitted to wrongful invasion of the ‘roof of the world’, hence there has been no acceptance of the Dalai Lama’s forgiveness. Can the Dalai Lama’s forgiving under these circumstances, however, still be seen as forgiveness? In the present contribution, I shed light on the Buddhist view on forgiveness in the hope of inspiring ideas that might contribute to the pursuit of peace. Firstly, I explore certain matters surrounding the general idea of forgiveness and subsequently introduce Buddhist perspectives. Secondly, I respond to the key question of this paper by highlighting the Dalai Lama’s views as a means to elaborate on the Buddhist stance. I conclude by comparing Buddhist points of view with some contemporary philosophical perspectives and illustrating some distinguishing features of the Buddhist notion of forgiveness. From the above, I endeavour to establish that the Buddhist take on forgiveness is ultimately unconditional. (shrink)

In last part of his life, Kuhn claimed that he is a post-Kantian in many aspects. This paper aims to inquire the post-Kantian thesis of Kuhn from two paths. One is metaphors in science, and the other is Kuhn's theory of concepts. Following Andersen, Barker and Chen , who apply the new results of cognitive psychology (particularly, the frame model of concept representation), I propose a reinterpretation of Kuhn' s latest philosophy of science.

If different translations of the same literary work have different syntaxes and semantics, how are they supposed to be about one and the same fictional character? In order to answer this question it’s necessary to (a) know what fictional characters are and (b) present reference conditions for them. Relying on Amie Thomasson’s (1999, 2003, 2007) and Saul Kripke’s (1980, 2013) works I argue that fictional characters are abstract artifacts whose reference is fixed by the baptism performed by an author; and (...) that the identity of a fictional character is preserved due to the maintenance of the same chain of reference. Finally, I show how translators maintain the chain of reference initiated by the author of a given work and how consequently a fictional character remains the same abstract artifact throughout different translations.

Intuitively there are many different things that non-derivatively contribute to well-being: pleasure, desire satisfaction, knowledge, friendship, love, rationality, freedom, moral virtue, and appreciation of true beauty. According to pluralism, at least two different types of things non-derivatively contribute to well-being. Lopsided lives score very low in terms of some types of things that putatively non-derivatively contribute to well-being, but very high in terms of other such types of things. I argue that pluralists essentially face a trilemma about lopsided lives: they (...) must either make implausible claims about how they compare in terms of overall well-being with more balanced lives, allow overall well-being to be implausibly hypersensitive to very slight nonevaluative differences, or else adopt implausible seeming limits on what things lives can contain or how much they can contribute to overall well-being. Such problems about lopsided lives thus push us away from pluralism and toward simpler theories of well-being, toward hedonism in particular. (This piece is the subject of Eden Lin’s paper “Well-Being and Hedonic Indispensability”.). (shrink)

One vexing question for Desire Satisfactionism is this: At what time do you benefit from a satisfied desire? Recently Eden Lin has proposed an intriguing answer. On this proposal – Asymmetrism – when past-directed desires are satisfied, the time interval during which you benefit is the time of the desire; and, when future-directed desires are satisfied, the time interval during which you benefit is the time of the object. In this essay, I argue that Asymmetrism forces us to give implausible (...) answers to a different question: To what extent does a given satisfied desire benefit you? (shrink)

Subjectivists about welfare face two problems that pull them in opposite directions. The Paradox Problem, outlined by Ben Bradley, is that, for an agent who desires that her life go badly, subjectivist theories are sometimes unable to give a determinate answer about how well her life goes. This problem demands that subjectivists choose a complex mental attitude to ground well-being. The Infant Problem, from Eden Lin, is that many subjective theories end up denying that infants (and some others) have welfare. (...) This problem demands that subjectivists choose a simple attitude to ground well-being. I argue that subjectivists should respond by adopting Disjunctive Subjectivism. Your welfare depends on your judgements that things are intrinsically good or bad for you (c.f. Dorsey), unless you are not capable of such judgements. In that case, it depends on your desires. I then defend DS against objections from Lin, and the potential charge of being ad hoc. (shrink)

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

Background: Food-borne outbreaks have been associated with sourcing unsafe food. Therefore, the first preventative strategy should be to source safe food. Even if the sourced food is safe, measures need to be put in place to ensure that it remains safe during the transfer, storage, preparation and serving activities that follow. An understanding of the ship food supply and transfer chain will help to illustrate the points at which the food can become contaminated en route to the point of consumption. (...) Objectives: The study was conducted in selected sea port in the core Niger Delta to assessed the microbiological quality of food served at different ship galley to crew and passengers and compared it to standard. Methods: Samples of food were taken from three (Port Harcourt Area one (PHSP), Warri (WSP) and Koko (KSP)) seaports within the South-South zone for laboratory analysis to uncover food spoilage microorganisms capable of causing disease outbreak among ship which could result to Transborder diseases. Eleven samples of different ready to eat food were collected from the locations, which included cooked rice; fried fish, irish potato porridge, vegetable soup, griki, pepper soup, fried irish potato, salad and bread were collected randomly. The samples were prepared and analyzed using standard procedures. Mean viable counts of aerobic and anaerobic bacteria were determined, ranging from (13×103cfu/g to 78×104 cfu/g) for ready to eat food. Results: Based on the finding KSP I, KSP J and KSP K food samples had the highest bacterial contamination on food while WSP F, WSP G and WSP H food samples had the least with the following isolates Salmonella spp, Nocardia spp, Shigella spp, Listeria spp, Bacillus cereus, Leuconostoc spp, Acinetobacter spp, Acetobacter spp, campylobacter spp, Clostridium spp and Vibrio spp which revealed that the isolates were susceptible to any of these antibiotics Septrin, Chloramphenicol, Gentamycin, Tarvid, Streptomycin, Reflacin, Augumetin, Ceporex, Nalidixic acid, Ampicillin, Ciproflox, Penicillin and Erythromycin. Conclusion: Thus, ships operators and regulatory body are expected to take all practicable measures to ensure that they do not receive unsafe or unsuitable food and maintain adequate food temperature at all time.

Spinoza’s conatus doctrine, the main proposition of which claims, “[e]ach thing, to the extent it is in itself, strives [conatur] to persevere in its being” (E3p6), has been the subject of growing interest. This is understandable, for Spinoza’s psychology and ethics are based on this doctrine. In my paper I shall examine the way Spinoza argues for E3p6 in its demonstration which runs as follows: "For singular things are modes by which God’s attributes are expressed in a certain and determinate (...) way (by 1p25c), i.e. (by 1p34), things that express, in a certain and determinate way, God’s power, by which God is and acts. And no thing has anything in itself by which it can be destroyed, or which takes its existence away (by p4). On the contrary, it is opposed to everything which can take its existence away (by p5). Therefore, to the extent it can, and is in itself, it strives to persevere in its being." This argument has been severely criticized for being defective in many ways. E3p6d contains four items, E1p25c, 1p34, 3p4, and 3p5. Most often, only the two last mentioned are regarded as doing any real work in the demonstration. However, I shall argue that having a proper grasp of Spinoza’s concept of power enables us see that the demonstration’s beginning, built on E1p25c and 1p34, brings forth a certain dynamic framework in which finite things are centers of causal power, capable of producing effects in virtue of their essences. My examination of this framework shows the beginning of the demonstration to be irreplaceable: in the end, conatus is one form of power, and E1p25c and 1p34 not only bring the notion of power into play, but also inform us on how finite things’ power should be understood in the monistic system. So, I disagree with such commentators as Jonathan Bennett, Edwin Curley, Daniel Garber, Michael Della Rocca, and Richard Manning, who see Spinoza as trying to derive the conatus doctrine from E3p4 and 3p5 alone; and I agree with Alexandre Matheron, Henry Allison, and Martin Lin, who stress the importance of E1p25c and 1p34. -/- However, this still leaves us the task of reconstructing the whole derivation and showing how its various ingredients fit together. If E1p25c and 1p34 are so important, could E3p6 not be derived from them alone, as Martin Lin has argued? In other words, why are E3p4 and 3p5 needed at all? To answer these questions I shall provide an interpretation of E3p6d that explains how the argument is supposed to work. E1p25c and 1p34 say that finite things are, in essence, dynamic causers, which, in case of opposition, truly resist opposing factors with their power and do not simply cease their causal activities whenever facing obstacles; in other words, they strive against any opposition. However, this is not enough to guarantee that they could not act self-destructively or restrain their own power, which would make them incapable of self-preservation. But this would go against E3p4, “No thing can be destroyed except through an external cause,” and Spinoza uses it to claim, “no thing has anything in itself by which it can be destroyed, or which takes its existence away.” So all this allows Spinoza to hold that finite things are consistent causers, that is, entities endowed with power and, insofar they cause effects solely in virtue of their essence, they never use their power self-destructively. The significance and role of the final item in the demonstration, E3p5 (“Things are of a contrary nature, i.e., cannot be in the same subject, insofar as one can destroy the other”), still needs to be determined. Indeed, considering its content and the way it is used in the demonstration, it seems to be a surprisingly decisive ingredient in the argument. Namely, what “each thing, to the extent it is in itself,” that is, insofar as any thing is considered disregarding everything external to it, strives to preserve, is its being (esse), not simply its present state. This together with E3p5’s view of subjecthood – which I shall explicate in my paper – suggests that we should rethink what kind of “being” or “existence” is meant in E3p6. Indeed, for Spinoza, each subject has a definable essence from which, as far as the subject in question is in itself, certain properties or effects necessarily follow; consequently a subject’s full being involves not only instantiating a certain essence, but also those properties inferable from the essence-expressing definition. Thus, E3p5 is meant to bring forward that things are not merely non-self-destroyers but subjects from whose definitions properties follow; and as Spinoza thinks to have shown (by E1p25c and 1p34) that finite modifications are entities endowed with power, any subject has true power to produce the properties or effects derivable from its definition, which, Spinoza claims, implies opposing everything harmful. In other words, things exercise power as their definition states, i.e. according to their definitions, and thus bringing in the idea of things as expressers of power enables Spinoza to convert logical oppositions (of E3p5) into real ones (of E3p6). To summarize, Spinoza reasons that each true finite thing is, in itself, an expresser of power (E1p25c, 1p34) that never acts self-destructively (E3p4) but instead strives to drive itself through opponents to produce effects as they follow from the definition of the thing in question (E1p25c, 1p34, and 3p5). Therefore, “each thing, to the extent it is in itself, strives to persevere in its being.” The demonstration of E3p6 has its roots deep in Spinoza’s ontology, and since its concept of power is supposed to provide the metaphysical grounding for real opposition, the importance of E1p25c and 1p34 should not be underestimated just because Spinoza – as often happens – puts his point exceedingly briefly. Moreover, the derivation is basically valid and contains no superfluous elements. Finally, all this tells us something decisive about the meaning of Spinoza’s doctrine: according to it, things are active causers whose “power to exist and act” has conatus character in temporality, amounting not only to striving to prolong the duration of one’s actualization but also to striving to be as active or autonomous as possible, that is, to attain a state determined by the striving subject’s essence alone.
