Based on its productionguideline, organic agriculture has set foritself the goals of minimizing all forms ofpollution and maintaining sustainability of thefarming system. By striving for these goals,organic farming meets the demands of anincreasing number of consumers who are criticalof conventional production methods. This papergives an overview of the present state of theart in the different issues. Possibilities ofand limitations in performing the self-aimedgoals under the basic standards of organicagriculture are discussed. Concerningenvironmental protection, in general, the riskof adverse environmental effects is (...) lower withorganic than with conventional farming methods,though not necessarily so; with reference tosoil fertility and nutrient management, organicfarming is suited to improve soil fertility andnutrient management markedly on the farm level;regarding biodiversity, comparison studies showthat organic farming has more positive effectson biodiversity conservation; in relation toproduct quality, under the basic standards oforganic farming, there is no sufficientevidence for a system-related effect on productquality due to the production method.

This book is an annotated translation of Changuan cejin: Whip for Spurring Students Onward Through the Chan Barrier Checkpoints (commonly abbreviated to Chan Whip).

This book explores how one can bring about changes in the brain through meditation, both through attention-focus training and through compassion training. Recent findings in the natural sciences have confirmed that it is possible for humans to achieve these structural and functional changes through various life-style practices. It is argued that meditation enables us to influence some aspects of our biological make-up and, for example, could boost our cognitive flexibility as well as our ability to act compassionate. Such changes are (...) likely to facilitate the instilling of a number of epistemic virtues which have great bearing on our quality of life. This book offers the reader an accessible introduction to a set of neuro-enhancement methods, with a special focus on meditation techniques, and explores how such practices could contribute to make us better decision-makers and improve our moral virtues. The book is suitable for anyone looking for a text discussing the effects of neuro-enhancement from a secular ethics perspective. (shrink)

It has been argued that affordances are not meaningful and are thus not useful to be applied in contexts where specifically meaningfulness of experience is at stake (e.g. clinical contexts or discussions of autonomous agency). This paper aims to reconceptualize affordances such as to make them relevant and applicable in such contexts. It starts by investigating the ‘ambiguity’ of (possibilities for) action. In both philosophy of action and affordance research, this ambiguity is typically resolved by adhering to the agents intentions (...) and concerns. I discuss some recent accounts of affordances that highlight these concerns but argue that they tend to adopt an ‘atomistic’ approach where there is no acknowledgement of how these concerns are embedded in the agents wider concerns, values, projects and commitments. An holistic approach that does acknowledge this can be found in psychological research on agents having a sense of what they’re doing. I will discuss this research in the second part of the paper and argue that agents can analogously have a sense of what is afforded. This is deemed the entry point for understanding the meaningfulness of affordances. In the final part of the paper I apply this analysis to recent attempts which seek to make sense of authentic and autonomous agency in terms of affordances. (shrink)

Orthodoxy in the contemporary debate on knowledge ascriptions holds that the truth‐value of knowledge ascriptions is purely a matter of truth‐relevant factors. One familiar challenge to orthodoxy comes from intuitive practical factor effects . But practical factor effects turn out to be hard to confirm in experimental studies, and where they have been confirmed, they may seem easy to explain away. We suggest a novel experimental paradigm to show that practical factor effects exist. It trades on the idea that people (...) retract knowledge attributions when practical factors shift. We also explain why the resulting data raise a serious challenge to orthodoxy. (shrink)

Epistemic invariantism, or invariantism for short, is the position that the proposition expressed by knowledge sentences does not vary with the epistemic standard of the context in which these sentences can be used. At least one of the major challenges for invariantism is to explain our intuitions about scenarios such as the so-called bank cases. These cases elicit intuitions to the effect that the truth-value of knowledge sentences varies with the epistemic standard of the context in which these sentences can (...) be used. In this paper, I will defend invariantism against this challenge by advocating the following, somewhat deflationary account of the bank case intuitions: Readers of the bank cases assign different truth-values to the knowledge claims in the bank cases because they interpret these scenarios such that the epistemic position of the subject in question differs between the high and the low standards case. To substantiate this account, I will argue, first, that the bank cases are underspecified even with respect to features that should uncontroversially be relevant for the epistemic position of the subject in question. Second, I will argue that readers of the bank cases will fill in these features differently in the low and the high standards case. In particular, I will argue that there is a variety of reasons to think that the fact that an error-possibility is mentioned in the high standards case will lead readers to assume that this error-possibility is supposed to be likely in the high standards case.

The recent literature abounds with accounts of the semantics and pragmatics of so-called predicates of personal taste, i.e. predicates whose application is, in some sense or other, a subjective matter. Relativism and contextualism are the major types of theories. One crucial difference between these theories concerns how we should assess previous taste claims. Relativism predicts that we should assess them in the light of the taste standard governing the context of assessment. Contextualism predicts that we should assess them in the (...) light of the taste standard governing the context of use. We show in a range of experiments that neither prediction is correct. People have no clear preferences either way and which taste standard they choose in evaluating a previous taste claim crucially depends on whether they start out with a favorable attitude towards the object in question and then come to have an unfavorable attitude or vice versa. We suggest an account of the data in terms of what we call hybrid relativism. (shrink)

This article brings together two sets of data that are rarely discussed in concert; namely, disagreement and testimony data. I will argue that relativism yields a much more elegant account of these data than its major rival, contextualism. The basic idea will be that contextualists can account for disagreement data only by adopting principles that preclude a simple account of testimony data. I will conclude that, other things being equal, we should prefer relativism to contextualism. In making this comparative point, (...) I will also defend self-standing relativist accounts of disagreement and testimony data. (shrink)

EDITOR’S ABSTRACTThe popular Chinese portrayal of the victory of Confucianism, or in Chinese terms “dismiss the hundred schools of thought and revere only the Confucian arts,” has been challenged by some scholars in the past decades. Ding’s essay illustrates not only how it has been challenged but also how the catch phrase influences the scholarly discussion. As he indicates, recent Chinese studies that attempt to subvert the traditional theory share the same “flow.” They fail to note that the expression (...) “dismiss the hundred schools of thought and revere only the Confucian arts” has had very negative connotations since it was invoked by Yi Baisha 易白沙 to harshly denounce Confucianism for being responsible for the centuries-long Chinese autocracy.

Can affordances help in understanding psychiatric illness and psychopathological experience? In recent work on the philosophy of psychiatry and phenomenology, the answer appears to be a clear ‘yes’, but some recent worries have emerged that the affordance-concept might be “insufficiently discerning” and thus ill-suited to make sense of psychiatric illness and experience. In this paper I briefly review recent attempts to use the affordance-concept to make sense of psychopathology, as well as the worries voiced by the critics. I argue that (...) much of this criticism is, in fact, best understood as a call for more research and offer some exploratory considerations on how this research might proceed. Specifically, I argue that an improved understanding of the self-referentiality that is inherent to experiencing affordances can be useful for psychiatry. (shrink)

Relativism entails that sentences like ‘Liquorice is tasty’ are used to assert relativistic propositions—that is, propositions whose truth-value is relative to a taste standard. I will defend this view against two objections. According to the first objection, relativism is incompatible with a Stalnakerian account of assertion. I will show that this objection fails because Stalnakerian assertions are proposals rather than attempts to update the common ground. According to the second objection, relativism problematically predicts that we can correctly assess beliefs as (...) false but faultless. I will show that it doesn't. Such assessments come out as incorrect because correct relativistic assertion requires the absence of a presupposition of non-commonality. (shrink)

This book shows how pressing issues in bioethics – e.g. the ownership of biological material and human cognitive enhancement – successfully can be discussed with in a virtue ethics framework. This is not intended as a complete or exegetic account of virtue ethics. Rather, the aim here is to discuss how some key ideas in Aristotle’s Nicomachean Ethics, when interpreted pragmatically, can be a productive way to approach some hot issues in bioethics. In spite of being a very promising theoretical (...) perspective virtue ethics has so far been underdeveloped both in bioethics and neuroethics and most discussions have been conducted in consequentialist and/or deontological terms. ​.

Moderate pragmatic invariantism (MPI) is a proposal to explain why our intuitions about the truth-value of knowledge claims vary with stakes and salient error-possibilities. The basic idea is that this variation is due to a variation not in the propositions expressed (as epistemic contextualists would have it) but in the propositions conversationally implicated. I will argue that MPI is mistaken: I will distinguish two kinds of implicature, namely, additive and substitutional implicatures. I will then argue, first, that the proponent of (...) MPI cannot appeal to additive implicatures because they don’t affect truth-value intuitions in the required way. Second, I will argue that the proponent of MPI cannot appeal to substitutional implicatures either because, even though they may have the required effects on truth-value intuitions, they don’t feature in the relevant cases. It follows that MPI is mistaken because whether the proponent of MPI appeals to additive or substitutional implicatures, at least one of the claims that make up her view is false. Along the way, I will suggest principles about implicatures that should be relevant not only to MPI, but to pragmatic accounts of seemingly semantic intuitions in general. (shrink)

It is commonly held that retraction data, if they exist, show that assessment relativism is preferable to non-indexical contextualism. I argue that this is not the case. Whether retraction data have the suggested probative force depends on substantive questions about the proper treatment of tense and location. One’s preferred account in these domains should determine whether one accepts assessment relativism or non-indexical contextualism.

In this paper, I will discuss what I will call “skeptical pragmatic invariantism” as a potential response to the intuitions we have about scenarios such as the so-called bank cases. SPI, very roughly, is a form of epistemic invariantism that says the following: The subject in the bank cases doesn’t know that the bank will be open. The knowledge ascription in the low standards case seems appropriate nevertheless because it has a true implicature. The goal of this paper is to (...) show that SPI is mistaken. In particular, I will show that SPI is incompatible with reasonable assumptions about how we are aware of the presence of implicatures. Such objections are not new, but extant formulations are wanting for reasons I will point out below. One may worry that refuting SPI is not a worthwhile project given that this view is an implausible minority position anyway. To respond, I will argue that, contrary to common opinion, other familiar objections to SPI fail and, thus, that SPI is a promising position to begin with. (shrink)

The mentioning of error-possibilities makes us less likely to ascribe knowledge. This paper offers a novel psychological account of this data. The account appeals to “subadditivity,” a well-known psychological tendency to judge possibilities as more likely when they are disjunctively described.

Episodic memories can no longer be seen as the re-activation of stored experiences but are the product of an intense construction process based on a memory trace. Episodic recall is a result of a process of scenario construction. If one accepts this generative framework of episodic memory, there is still a be big gap in understanding the role of the narrative self in shaping scenario construction. Some philosophers are in principle sceptic by claiming that a narrative self cannot be more (...) than a causally inefficacious attributed entity anyway. Thus, we first characterize a narrative self in detail and second we clarify its influential causal role in shaping our episodic memories by influencing the process of scenario construction. This happens at three stages, namely at the level of the input, the output and the process of scenario construction. (shrink)

This paper presents a novel understanding of the notion of calculability. In Gricean frameworks, calculability is defined in terms of how speakers can infer an implicature. The relevant inferences must e.g. be based on maxims of conversation or cooperation principles. Meanwhile, I suggest to define calculability in terms of when, or under which conditions, speakers can infer an implicature. An implicature is calculable if hearers can infer its existence even supposing that the implicature is not semantically encoded. This approach avoids (...) familiar challenges, including recently prominent challenges from pragmatic particularism. (shrink)

EDITOR’S ABSTRACTThis article argues that the early Laozi text underwent three stages: The first had section divisions on the basis of the meaning. The second stage was the formative period of the Laozi text influenced by cosmological numerology; the Silk Manuscript version A is its testimony. The third stage finalized the text through the canonization of the Classic by Emperor Jing; it is represented by the Peking University Han Bamboo Slips, Yan Zun, and Liu Xiang versions and became the received (...) edition. From the Han Bamboo Slips to the Liu Xiang version, the Laozi’s two parts and section numbering became increasingly balanced and symmetric. Ding urges scholars to pay attention to all these developments when studying the Laozi text. (shrink)

While many authors distinguish belief from acceptance, it seems almost universally agreed that no similar distinction can be drawn between degrees of belief, or credences, and degrees of acceptance. I challenge this assumption in this paper. Acceptance comes in degrees and acknowledging this helps to resolve problems in at least two philosophical domains. Degrees of acceptance play vital roles when we simplify our reasoning, and they ground the common ground of a conversation if we assume context probabilism, i.e., that the (...) common ground must be represented with probability spaces rather than possible worlds.

Communication can be risky. Like other kinds of actions, it comes with potential costs. For instance, an utterance can be embarrassing, offensive, or downright illegal. In the face of such risks, speakers tend to act strategically and seek ‘plausible deniability’. In this paper, we propose an account of the notion of deniability at issue. On our account, deniability is an epistemic phenomenon. A speaker has deniability if she can make it epistemically irrational for her audience to reason in certain ways. (...) To avoid predictable confusion, we distinguish deniability from a practical correlate we call ‘untouchability’. Roughly, a speaker has untouchability if she can make it practically irrational for her audience to act in certain ways. These accounts shed light on the nature of strategic speech and suggest countermeasures against strategic speech. (shrink)

Doxastic dualists acknowledge both outright beliefs and credences, and they maintain that neither state is reducible to the other. This gives rise to the ‘Bayesian Challenge’, which is to explain why we need beliefs if we have credences already. On a popular dualist response to the Bayesian Challenge, we need beliefs to simplify our reasoning. I argue that this response fails because credences perform this simplifying function at least as well as beliefs do.

Relativism and contextualism have been suggested as candidate semantics for “knowledge” sentences. I argue that relativism faces a problem concerning the preservation of beliefs in memory. Contextualism has been argued to face a similar problem. I argue that contextualists, unlike relativists, can respond to the concern. The overall upshot is that contextualism is superior to relativism in at least one important respect.

Many experiential properties are naturally understood as dispositions such that e.g. a cake tastes good to you iff you are disposed to get gustatory pleasure when you eat it. Such dispositional analyses, however, face a challenge. It has been widely observed that one cannot properly assert “The cake tastes good to me” unless one has tried it. This acquaintance requirement is puzzling on the dispositional account because it should be possible to be disposed to like the cake even if this (...) disposition has never been manifested. We argue that familiar response strategies on behalf of the dispositionalist fail. These include appeals to conversational implicatures, expressivism, semantic presuppositions and norms of assertion. Against this background, we propose a new analysis in terms of what we call tendencies, where a tendency is a disposition that has been manifested. The acquaintance requirement comes out as an entailment. We point out a hitherto unnoticed parallel to sentences ascribing character traits such as “Hannah is brave,” and extend our tendency-based analysis to this domain. (shrink)

In this paper we investigate problems about densities ofe-generic,s-generic andp-generic degrees. We, in particular, show that allp-generic degrees are non-branching, which answers an open question by Jockusch who asked: whether alls-generic degrees are non-branching and refutes a conjecture of Ingrassia; the set of degrees containing r.e.p-generic sets is the same as the set of r.e. degrees containing an r.e. non-autoreducible set.

This article explores from a semiotic perspective the structural features of the ‘poetic logic’ that lies behind metonymy and metaphor. More specifi-cally, it treats metonymy and metaphor not as ‘abnormal’ uses of language but as the results of the same indexical and iconic ways of thinking that we see elsewhere in our lives. The paper also brings to bear on the topic of metaphor some important insights from the late Chinese scholar Qian Zhong-shu, whose ‘two handles and several sides’ theory (...) of metaphor seems to complement contemporary Western ‘metaphorology’ very well.
