When inventing a situation that does not still exist, an engineer design new technical objects, fostering his capacities of observation, analysis and creativity. How develop those capacities in technical higher education by using knowledge and tools of design sciences? Design sciences mainly pay attention on the object to design, the process and reject the designer as a subject of his activity. We mobilize analysis of activity and human sciences for taking into account the designer as a full person with his (...) identity, his singularity and being author of his activity. We offer to analyse the epistemological gap between design and human sciences by reflecting an experience of learning inventive design in a French engineering school. We finally show that appear a paradox linked to design sciences. Before being inventive, design sciences are reproductive. Inventive design is outside design sciences, mainly in human interactions.

Dark matter is a fundamental component of the standard cosmological model, but in spite of four decades of increasingly sensitive searches, no-one has yet detected a single dark-matter particle in the laboratory. An alternative cosmological paradigm exists: MOND (Modified Newtonian Dynamics). Observations explained in the standard model by postulating dark matter are explained in MOND by proposing a modification of Newton's laws of motion. Both MOND and the standard model have had successes and failures – but only MOND has repeatedly (...) predicted observational facts in advance of their discovery. In this volume, David Merritt outlines why such predictions are considered by many philosophers of science to be the 'gold standard' when it comes to judging a theory's validity. In a world where the standard model receives most attention, the author applies criteria from the philosophy of science to assess, in a systematic way, the viability of this alternative cosmological paradigm.

We start by presenting three different views that jointly imply that every person has many conscious beings in their immediate vicinity, and that the number greatly varies from person to person. We then present and assess an argument to the conclusion that how confident someone should be in these views should sensitively depend on how massive they happen to be. According to the argument, sometimes irreducibly de se observations can be powerful evidence for or against believing in metaphysical theories.

Explores the cosmological and metaphysical thought in the Zhuangzi from the perspective of nothingness. Zhuangzi and the Becoming of Nothingness offers a radical rereading of the Daoist classic Zhuangzi by bringing to light the role of nothingness in grounding the cosmological and metaphysical aspects of its thought. Through a careful analysis of the text and its appended commentaries, David Chai reveals not only how nothingness physically enriches the myriad things of the world, but also why the Zhuangzi prefers nothingness (...) over being as a means to expound the authentic way of Dao. Chai weaves together Dao, nothingness, and being in order to reassess the nature and significance of Daoist philosophy, both within its own historical milieu and for modern readers interested in applying the principles of Daoism to their own lived experiences. Chai concludes that nothingness is neither a nihilistic force nor an existential threat; instead, it is a vital component of Dao’s creative power and the life-praxis of the sage. “Chai provides an elaborate philosophical meontological interpretation of the ontology/cosmology found in the Zhuangzi and the implications for existential practice. It’s a close, careful, but in many respects quite original reading of the classic that contributes significantly to the field of philosophical Daoist studies.” — Geir Sigurðsson, author of Confucian Propriety and Ritual Learning: A Philosophical Interpretation.

In this classic, David Bohm was the first to offer us his causal interpretation of the quantum theory. _Causality and Chance in Modern Physics_ continues to make possible further insight into the meaning of the quantum theory and to suggest ways of extending the theory into new directions.

Epistemologists have recently proposed a number of norms governing rational inquiry. My aim in this paper is to unify and explain recently proposed norms of inquiry by developing a general account of the conditions under which inquiries are rational, analogous to theories such as evidentialism and reliabilism for rational belief. I begin with a reason-responsiveness conception of rationality as responding correctly to possessed normative reasons. I extend this account with a series of claims about the normative reasons for inquiry that (...) we possess. I apply the account to shed light on two classes of norms that have featured prominently in recent discussions: norms of clutter avoidance forbidding agents from engaging in trivial inquiries, and norms of logical non-omniscience governing properties such as the deductive closure and consistency of an agent's belief state. I conclude with a discussion of the sense in which norms of inquiry should be regarded as epistemic norms. (shrink)

David McNeill, a pioneer in the ongoing study of the relationship between gesture and language, here argues that gestures are active participants in both speaking and thinking. He posits that gestures are key ingredients in an “imagery-language dialectic” that fuels speech and thought. The smallest unit of this dialectic is the growth point, a snapshot of an utterance at its beginning psychological stage. In _Gesture and Thought,_ the central growth point comes from a Tweety Bird cartoon. Over the course (...) of twenty-five years, the McNeill Lab showed this cartoon to numerous subjects who spoke a variety of languages, and a fascinating pattern emerged. The shape and timing of gestures depends not only on what speakers see but on what they take to be distinctive; this, in turn, depends on the context. Those who remembered the same context saw the same distinctions and used similar gestures; those who forgot the context understood something different and changed gestures or used none at all. Thus, the gesture becomes part of the growth point—the building block of language and thought. _Gesture and Thought _is an ambitious project in the ongoing study of how we communicate and how language is connected to thought.

This paper is an explication of Gadamer's idea of "application." I argue that the relation between the first and third persons in application contains a viable conception of the normativity of understanding. Application includes a measure for understanding. The thing that is to be understood must be allowed to address me, and such involvement responds to the text’s meaning. While this measure is not expressible in principled rules, application is normatively accountable both to the text’s third-person claim to meaning and (...) to my first-person involvement with the text. The participation of the interpreter with the item of her understanding forms a normative standard. (shrink)

The notion of natural kinds has been widely criticized in philosophy of science but also appears indispensable for philosophical engagement with classificatory practices. Rather than addressing this tension through a new definition of “natural kind”, this article suggests materiality as a substitute for naturalness in philosophical debates about scientific classification. It is argued that a theory of material kinds provides an alternative and more inclusive entry point for analyzing classificatory practices, which is specified through an account of “restricted malleability” of (...) materiality and further analyzed as (1) gradual, (2) multi-dimensional, (3) scalable, (4) interactive, and (5) purpose sensitive.

David Bloor provides a challenging and informative evaluation of Wittgenstein's account of rules and rule-following. Arguing for a collectivist reading, Bloor offers the first consistent sociological interpretation of Wittgenstein's work for many years.

David Miller is the foremost exponent of the purist critical rationalist doctrine and here presents his mature views, discussing the role that logic and argument play in the growth of knowledge, criticizing the common understanding of argument as an instrument of justification, persuasion or discovery and instead advocating the critical rationalist view that only criticism matters. Miller patiently and thoroughly undoes the damage done by those writers who attack critical rationalism by invoking the sterile mythology of induction and justification (...) that it seeks to sweep away. In addition his new material on the debate on verisimilitude is essential reading for all working in this field. (shrink)

Psychological and philosophical studies have extended J. J. Gibson’s notion of affordances. Affordances are possibilities for bodily action presented to us by the objects of our perception. Recent work has argued that we should extend the actions afforded by perception to mental action. I argue that we can extend the notion of affordance itself. What I call ‘Introspective Affordances’ are possibilities for mental action presented to us by introspectively accessible states. While there are some prima facie worries concerning the non-perceptual (...) nature of introspection, I will argue that our internal mental lives share enough commonalities with experiences in our environment to warrant this extension. I will demonstrate the value of introspective affordances by showing how they allow us to explain an underexplored aspect of thought insertion. (shrink)

There is a difference between merely thinking that P and really grasping that P. For example, Jackson's (1982) black-and-white Mary cannot (before leaving her black-and-white room) fully grasp what it means to say that fire engines are red, but she can perfectly well entertain the thought that fire engines are red. The contrast between merely thinking and grasping is especially salient in the context of certain moral decisions. For example, an individual who grasps the plight of starving children thanks to (...) evocative images seems much more likely to donate for the children's benefit than someone who is merely told about their plight. This paper offers a phenomenal account of grasping according to which grasping a content (whether a proposition or concept) consists in one's thoughts about the content being constituted by phenomenal experiences of constituents of the content. This account improves on earlier phenomenal accounts of grasping (Bourget 2017a, 2018) by allowing for partial grasping and generalizing to concepts. The paper also addresses objections to phenomenal accounts of grasping, including the objection that recent developments in AI technology show that consciousness is irrelevant to grasping and understanding.

Critical comments on Guido Melchior’s book, Knowing and Checking: An Epistemological Investigation (2019). In the second part of his book, Melchior aims to employ his sensitivity account of the epistemic concept of checking to explain well-known puzzle cases about knowing. My comments focus on Melchior’s explanation of knowledge-closure puzzles, as exemplified by Dretske’s zebra case. I raise three critical points about the explanation Melchior proposes for puzzles of this type.

It is a challenge to explain how evolutionary altruism can evolve by the process of natural selection, since altruists in a group will be less fit than the selfish individuals in the same group who receive benefits but do not make donations of their own. Darwin proposed a theory of group selection to solve this puzzle. Very simply, even though altruists are less fit than selfish individuals within any single group, groups of altruists are more fit than groups of selfish (...) individuals. If a population is subdivided into many groups that vary in their altruistic tendencies, altruism will be favored at the level of selection among groups even as it is being disfavored at the level of selection among individuals within groups. Darwin’s scenario became the basis for a theoretical framework called multilevel selection theory. (shrink)

The resemblance theory of representation is the view that one thing represents another by virtue of resembling it. Typically, it is taken as non-controversial that Berkeley accepts the resemblance theory of representation – even if the plausibility of the resemblance theory itself comes under scrutiny. One piece of evidence in favour of this reading of Berkeley is his commitment to the ‘likeness principle’: the view that ‘an idea can be like nothing but an idea’ (PHK § 8). The likeness principle (...) is typically seen as a rejection of the kind of indirect theory of perception that is often attributed to Locke. However, by paying particular attention to Berkeley’s account of how mental representation via the imagination works, Dávid Bartha casts doubt on the consensus view that Berkeley does accept the resemblance theory of representation.

According to the Principle of Sufficient Reason, every fact has an explanation. An important challenge to this principle is that it risks being a counterexample to itself. What explains why everything needs to be explained? My first goal is to distinguish two broad kinds of answers to this question, which I call “Humean Rationalism” and “Non-Humean Rationalism”. My second goal will be to defend the prospects of Humean Rationalism.

Epistemology has taken a zetetic turn from the study of belief towards the study of inquiry. Several decades ago, theories of bounded rationality took a procedural turn from attitudes towards the processes of inquiry that produce them. What is the relationship between the zetetic and procedural turns? In this paper, I argue that we should treat the zetetic turn in epistemology as part of a broader procedural turn in the study of bounded rationality. I use this claim to motivate and (...) clarify the zetetic turn in epistemology, as well as to reveal the need for a second zetetic turn within practical philosophy. (shrink)

Consider the following two (hypothetical) generic causal claims: “Living in a neighborhood with many families with children increases purchases of bicycles” and “living in an affluent neighborhood with many families with children increases purchases of bicycles.” These claims not only differ in what they suggest about how bicycle ownership is distributed across different neighborhoods (i.e., “the data”), but also have the potential to communicate something about the speakers’ values: namely, the prominence they accord to affluence in representing and making decisions (...) about the social world. Here, we examine the relationship between the level of granularity with which a cause is described in a generic causal claim (e.g., neighborhood vs. affluent neighborhood) and the value of the information contained in the causal model that generates that claim. We argue that listeners who know any two of the following can make reliable inferences about the third: 1) the level of granularity at which a speaker makes a generic causal claim, 2) the speaker’s values, and 3) the data available to the speaker. We present results of four experiments (N=1,323) in the domain of social categories that provide evidence in keeping with these predictions. (shrink)

David Albert claims that classical electromagnetic theory is not time reversal invariant. He acknowledges that all physics books say that it is, but claims they are ``simply wrong" because they rely on an incorrect account of how the time reversal operator acts on magnetic fields. On that account, electric fields are left intact by the operator, but magnetic fields are inverted. Albert sees no reason for the asymmetric treatment, and insists that neither field should be inverted. I argue, to (...) the contrary, that the inversion of magnetic fields makes good sense and is, in fact, forced by elementary geometric considerations. I also suggest a way of thinking about the time reversal invariance of classical electromagnetic theory -- one that makes use of the invariant (four-dimensional) formulation of the theory -- that makes no reference to magnetic fields at all. It is my hope that it will be of interest in its own right, Albert aside. It has the advantage that it allows for arbitrary curvature in the background spacetime structure, and is therefore suitable for the framework of general relativity. (The only assumption one needs is temporal orientability.). (shrink)

Many policies hinge on determining whether someone’s situation is due to luck or choice. In political philosophy, this prevalence is mirrored by luck egalitarian theories. But overemphasizing the distinction between luck and choice will lead to tensions with the value of moral agency, on which the distinction is grounded.

Elaborating on this conflict, (...) we argue that it should lead us to modify how luck and choice are used in theories of justice. (shrink)

Rhetorically charged debates over theory have divided scholars of the humanities for decades. In Elegy for Theory, D. N. Rodowick steps back from well-rehearsed arguments pro and con to assess why theory has become such a deeply contested concept. Far from lobbying for a return to the "high theory" of the 1970s and 1980s, he calls for a vigorous dialogue on what should constitute a new, ethically inflected philosophy of the humanities. Rodowick develops an ambitiously cross-disciplinary critique of theory as (...) an academic discourse, tracing its historical displacements from ancient concepts of theoria through late modern concepts of the aesthetic and into the twentieth century. The genealogy of theory, he argues, is constituted by two main lines of descent—one that goes back to philosophy and the other rooted instead in the history of positivism and the rise of the empirical sciences. Giving literature, philosophy, and aesthetics their due, Rodowick asserts that the mid-twentieth-century rise of theory within the academy cannot be understood apart from the emergence of cinema and visual studies. To ask the question, "What is cinema?" is to also open up in new ways the broader question of what is art. At a moment when university curriculums are everywhere being driven by scientism and market forces, Elegy for Theory advances a rigorous argument for the importance of the arts and humanities as transformative, self-renewing cultural legacies.

In the ancient conversation between Western philosophy and Christian theology, powerful contemporary voices are arguing for monologue rather than dialogue. Instead of these two disciplines learning from and mutually informing each other, both philosophers and theologians are increasingly disconnected from, and thus unable to hear, what the other is saying, especially in Anglo-American scholarship. Some Christian philosophers are now found claiming methodological authority over doctrine, while some Christian theologians even deny that philosophy has its own integrity as a separate discipline. (...) Against these trends, David Brown has argued over the past thirty years that philosophy and theology are both necessary in order to grapple with the reality of divine mystery and Christian faith. Neither discipline can be reduced to the other, and each has its own contribution to make for a full understanding of what Brown describes as 'a single vision' of God. In this volume, Brown addresses some key topics in philosophical theology, including the created order, experience and revelation, incarnation and redemption, and heaven and our communal destiny. Combining analytic clarity, doctrinal substance, and historical depth, this volume exemplifies Brown's project of truly integrating philosophy and theology. It thus provides an ideal introduction to this vital conversation for undergraduate and postgraduate students, as well as a connected argument of interest to specialists in both disciplines.

Presentism and Eternalism are competing views about the ontological and temporal structure of the world, introduced and demarcated by their answers to questions about what exists and whether what exists changes.

This essay examines the philosophical significance of $\Omega$-logic in Zermelo-Fraenkel set theory with choice (ZFC). The categorical duality between coalgebra and algebra permits Boolean-valued algebraic models of ZFC to be interpreted as coalgebras. The hyperintensional profile of $\Omega$-logical validity can then be countenanced within a coalgebraic logic. I argue that the philosophical significance of the foregoing is two-fold. First, because the epistemic and modal and hyperintensional profiles of $\Omega$-logical validity correspond to those of second-order logical consequence, $\Omega$-logical validity is genuinely (...) logical. Second, the foregoing provides a hyperintensional account of the interpretation of mathematical and metamathematical vocabulary. (shrink)

There is an apparent tension in Shepherd’s accounts of space and time. Firstly, Shepherd explicitly claims that we know that the space and time of the unperceived world exist because they cause our phenomenal experience of them. Secondly, Shepherd emphasizes that empty space and time do not have the power to effect any change in the world. My proposal is that for Shepherd time has exactly one causal power: to provide for the continued existence of self-same or changing objects. Because (...) Shepherd takes causation to be a relation whereby two objects combine to form a third, their effect, whenever we perceive a continually existing object, since time is a proper part of such objects, our perception of time is caused by time itself. Likewise, space’s causal power is to provide for the possibility of the motion or rest of objects, and so when we perceive objects with space as a proper part, we come into causal contact with space.

Cet article s’intéresse à la manière dont Aristote utilise l’hylémorphisme pour son explication de la reproduction sexuée dans la Génération des animaux. Il se concentre sur GA I 19 où Aristote établit que les menstrues sont analogues au sperma. Dans les théories de la double semence, le mâle et la femelle apportent l’un et l’autre une contribution de statut causal identique. Aristote montre au contraire que les menstrues ne sont pas du sperma ; menstrues et sperma jouent deux fonctions causales (...) différentes dans la génération : les menstrues apportent la matière et le sperma, la cause motrice et la forme. Mais l’hylémorphisme suppose qu’il existe aussi une identité entre les deux contributions, puisque la matière menstruelle est en puissance ce que les mouvements de la semence du mâle sont en entéléchie. Aristote maintient donc une identité entre les deux contributions. Il la conçoit de deux façons : le plus souvent comme une identité analogique (les menstrues sont analogues au sperma), parfois comme une identité quasi générique (semence et menstrues sont l’un et l’autre du sperma, moins élaboré dans le cas des menstrues). Aristote hésite entre ces deux solutions : dans le premier cas, le dernier résidu utile devient ou menstrues ou sperma ; dans l’autre, c’est le sperma qui devient menstrues chez la femelle ou semence chez le mâle. Aristote semble avoir hésité à considérer que le sperma est forme, chez le mâle, et matière, chez la femelle, ce qui l’aurait conduit à afficher une sorte de théorie du double sperma, chose qu’il refuse en vertu de l’identité profonde qui existe selon lui entre les menstrues et la semence du mâle.

This paper explores the topic of military ethics, what we mean by that term, what it covers, how it is understood, and how it is taught. It suggests that the unifying factor that makes this a coherent subject beyond individual national interpretations of it is the core idea of military professionalism. The paper draws out the distinction between training and education and draws on research conducted by a number of different people and agencies, including the International Committee of the Red (...) Cross, to establish what factors contribute to effective pedagogy and the inculcation of appropriate attitudes and behaviours. The paper concludes by looking at the way military ethics contributes to military outcomes from protecting civilians and the vulnerable to building resilience in our own military personnel to protect their mental health, through to the strategic costs of losing the moral high ground if behaviour is seen to fall short of that expected from military professionals.

Know how and ability have a seemingly fraught relationship. I deepen the tension here, by arguing for two new pieces of data concerning know how and ability. First, know how ascriptions have two distinct readings that differ in their entailments to ability: one entails ability, the other does not. Second, in certain cases, the indeterminacy of certain ability claims infects both readings of know how claims. No existing accounts of the relationship between know how and ability captures both data points, (...) I argue; but a certain kind of intellectualism has special resources to account for them. Ascriptions of knowledge of infinitival questions give rise to a distinctive kind of context-sensitivity specific to infinitivals. I show how on an intellectualist view where, very roughly, knowing how to do something is knowing an answer to an infinitival question about your abilities, this context-sensitivity accounts for the relationship between know how and ability.

Ways of the Hand tells the story of how David Sudnow learned to improvise jazz on the piano. Because he had been trained as an ethnographer and social psychologist, Sudnow was attentive to what he experienced in ways that other novice pianists are not.

He realized that he could now do a much better job of describing his experiences in a way that would not require facility with formal social science and philosophical discourse. The result is a revised version of the book that carries the same intellectual energy as the original but is accessible to a much wider audience. (shrink)

In the early seventeenth century Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed--from Kepler to Newton to Einstein. But in the early twentieth (...) century when quantum physics, with its deeply complex mathematics, entered into the picture, something began to change. Many physicists began looking to the equations first and physical reality second. As we investigate realms further and further from what we can see and what we can test, we must look to elegant, aesthetically pleasing equations to develop our conception of what reality is. As a result, much of theoretical physics today is something more akin to the philosophy of Plato than the science to which the physicists are heirs. In The Dream Universe, Lindley asks what is science when it becomes completely untethered from measurable phenomena? (shrink)

This book concerns the foundations of epistemic modality and hyperintensionality and their applications to the philosophy of mathematics. I examine the nature of epistemic modality, when the modal operator is interpreted as concerning both apriority and conceivability, as well as states of knowledge and belief. The book demonstrates how epistemic modality and hyperintensionality relate to the computational theory of mind; metaphysical modality and hyperintensionality; the types of mathematical modality and hyperintensionality; to the epistemic status of large cardinal axioms, undecidable propositions, (...) and abstraction principles in the philosophy of mathematics; to the modal and hyperintensional profiles of the logic of rational intuition; and to the types of intention, when the latter is interpreted as a hyperintensional mental state. Chapter 2 argues for a novel type of expressivism based on the duality between the categories of coalgebras and algebras, and argues that the duality permits of the reconciliation between modal cognitivism and modal expressivism. I also develop a novel topic-sensitive truthmaker semantics for dynamic epistemic logic, and develop a novel dynamic epistemic two-dimensional hyperintensional semantics. Chapter 3 provides an abstraction principle for epistemic (hyper-)intensions. Chapter 4 advances a topic-sensitive two-dimensional truthmaker semantics, and provides three novel interpretations of the framework along with the epistemic and metasemantic. Chapter 5 applies the fixed points of the modal μ-calculus in order to account for the iteration of epistemic states in a single agent, by contrast to availing of modal axiom 4 (i.e. the KK principle). The fixed point operators in the modal μ-calculus are rendered hyperintensional, which yields the first hyperintensional construal of the modal μ-calculus in the literature and the first application of the calculus to the iteration of epistemic states in a single agent instead of the common knowledge of a group of agents. Chapter 6 advances a solution to the Julius Caesar problem based on Fine's `criterial' identity conditions which incorporate conditions on essentiality and grounding. Chapter 7 provides a ground-theoretic regimentation of the proposals in the metaphysics of consciousness and examines its bearing on the two-dimensional conceivability argument against physicalism. The topic-sensitive epistemic two-dimensional truthmaker semantics developed in chapters 2 and 4 are availed of in order for epistemic states to be a guide to metaphysical states in the hyperintensional setting. Chapters 8-12 provide cases demonstrating how the two-dimensional hyperintensions of hyperintensional, i.e. topic-sensitive epistemic two-dimensional truthmaker, semantics, solve the access problem in the epistemology of mathematics. Chapter 8 examines the interaction between my hyperintensional semantics and the axioms of epistemic set theory, large cardinal axioms, the Epistemic Church-Turing Thesis, the modal axioms governing the modal profile of Ω-logic, Orey sentences such as the Generalized Continuum Hypothesis, and absolute decidability. These results yield inter alia the first hyperintensional Epistemic Church-Turing Thesis and hyperintensional epistemic set theories in the literature. Chapter 9 examines the modal and hyperintensional commitments of abstractionism, in particular necessitism, and epistemic hyperintensionality, epistemic utility theory, and the epistemology of abstraction. I countenance a hyperintensional semantics for novel epistemic abstractionist modalities. I suggest, too, that observational type theory can be applied to first-order abstraction principles in order to make first-order abstraction principles recursively enumerable, i.e. Turing machine computable, and that the truth of the first-order abstraction principle for hyperintensions is grounded in its being possibly recursively enumerable and the machine being physically implementable. Chapter 10 examines the philosophical significance of hyperintensional Ω-logic in set theory and discusses the hyperintensionality of metamathematics. Chapter 11 provides a modal logic for rational intuition and provides a hyperintensional semantics. Chapter 12 avails of modal coalgebras to interpret the defining properties of indefinite extensibility, and avails of hyperintensional epistemic two-dimensional semantics in order to account for the interaction between the interpretational and objective modalities and truthmakers thereof. This yields the first hyperintensional category theory in the literature. I invent a new mathematical trick in which first order structures are treated as categories, and Vopenka's principle can be satisfied because of the elementary embeddings between the categories and generate Vopenka cardinals while bypassing the category of Set in category theory. Chapter 13 examines modal responses to the alethic paradoxes. Chapter 14 examines, finally, the modal and hyperintensional semantics for the different types of intention and the relation of the latter to evidential decision theory. (shrink)

This interdisciplinary exploration discusses the intricate conceptual linkages among Buddhism’s Eighth State of Consciousness, Quantum Holography, and the Jungian Collective Unconscious. Central to this study is examining the Eighth Consciousness in Buddhist thought—a realm that transcends the conventional sensory and mental states to connect with a more universal and profound awareness. Drawing parallels, Quantum Holography posits that every part of the universe retains information about the whole, much like a hologram. This notion seemingly mirrors the Jungian concept of the Collective (...) Unconscious, which postulates a shared reservoir of memories and ideas across humanity. The paper contends that the intricate dance of photons, oscillating between particle and wave states, mediates perception through resonance and hints at a multi-layered consciousness stratum that mirrors the vast, enigmatic quantum reality expanse. The study illuminates the intersections and divergences among these frameworks through meticulous comparative analysis, positing that an integrative understanding of quantum theories and Buddhist wisdom can unravel the human psyche’s profound depths. By weaving Eastern philosophies with Western psychological and quantum theoretical tapestry, the discourse unveils a multifaceted consciousness comprehension, championing integrative approaches as invaluable tools for decoding the mind and universe's enigmatic interplay from a quantum viewpoint.

Agents sometimes have a final, de dicto desire to do what is right. They desire to do what is right for its own sake and under this description. These agents have pure moral motivation (PMM). It is often surmised that PMM is in some sense defective. Most famously, it has been suggested that PMM manifests a kind of moral fetishism. However, it also seems defective if an agent shows no concern whatsoever for moral rightness in their motivations. In this paper, (...) I attempt to resolve this puzzling tension. I argue, first, that PMM is defective insofar as it manifests a failure to respond to reasons. I argue, second, that not every instance of PMM manifests a responsiveness failure. In particular, we need to distinguish between the de dicto final desire to do what is right and the de dicto final desire to do what is right for the right reasons. (shrink)

According to a popular idea, freedom is grounded in orthonomy – the ability to be responsive to normative demands. But how exactly must an agent’s action relate to their reasons in order for this orthonomous relationship to hold? In this paper, I propose a novel explanationist answer to this question. I argue that extant answers – causalism and modalism about orthonomy – fail because they fail to account for the fact that intuitions about freedom and orthonomy track facts about explanation. (...) And these facts cannot be reduced to either causal or modal facts. Instead, I propose that we should understand freedom as grounded in special accidentality-dispersing explanations in terms of normative reasons. The resultant view is to be understood as following a Frankfurtian intuition: only factors that explain action can be relevant to whether the action is free. (shrink)
