It is argued that quantum theory is best understood as requiring an ontological duality of res extensa and res potentia, where the latter is understood per Heisenberg’s original proposal, and the former is roughly equivalent to Descartes’ ‘extended substance.’ However, this is not a dualism of mutually exclusive substances in the classical Cartesian sense, and therefore does not inherit the infamous ‘mind-body’ problem. Rather, res potentia and res extensa are proposed as mutually implicative ontological extants that serve to explain the (...) key conceptual challenges of quantum theory; in particular, nonlocality, entanglement, null measurements, and wave function collapse. It is shown that a natural account of these quantum perplexities emerges, along with a need to reassess our usual ontological commitments involving the nature of space and time. (shrink)

The Frauchiger–Renner Paradox is an extension of paradoxes based on the “Problem of Measurement,” such as Schrödinger’s Cat and Wigner’s Friend. All these paradoxes stem from assuming that quantum theory has only unitary physical dynamics, and the attendant ambiguity about what counts as a ‘measurement’—i.e., the inability to account for the observation of determinate measurement outcomes from within the theory itself. This paper discusses a basic inconsistency arising in the FR scenario at a much earlier point than the derived contradiction: (...) namely, the inconsistency inherent in treating an improper mixture as a proper, epistemic mixture. This is an illegitimate procedure that is nevertheless endemic if quantum theory is assumed to be always unitary. In contrast, under a non-unitary account of quantum state reduction yielding determinate outcomes, the use of a proper mixture for measurement results becomes legitimate, and this entire class of paradoxes cannot be mounted. The conclusion is that the real lesson of the FR paradox is that it is the unitary-only assumption that needs to be critically reassessed. (shrink)

In view of a resurgence of concern about the measurement problem, it is pointed out that the Relativistic Transactional Interpretation remedies issues previously considered as drawbacks or refutations of the original TI. Specifically, once one takes into account relativistic processes that are not representable at the non-relativistic level, absorption is quantitatively defined in unambiguous physical terms. RTI therefore provides a well-defined terminus to what appears to be a necessary infinite regress concerning ‘absorption’ when only the non-relativistic level is considered. In (...) addition, specifics of the relativistic transactional model demonstrate that the Maudlin ‘contingent absorber’ challenge to the original TI cannot even be mounted: basic features of established relativistic field theories dictate that the ‘slow-moving offer wave’ required for the challenge scenario cannot exist. It is concluded that issues previously considered obstacles for TI are no longer legitimately viewed as such, and that reconsideration of the transactional picture is warranted in connection with solving the measurement problem.

Explanations in psychiatry often integrate various factors relevant to psychopathology. Identifying genuine causes among them is theoretically and clinically important, but epistemically challenging. Woodward’s interventionism appears to provide a promising tool to achieve this. However, Woodward’s interventionism is too demanding to be applied to psychiatry. I thus introduce difference-making interventionism, which detects relevance in general rather than causation, to make interventionist reasoning viable in clinical practice. DMI mirrors the empirical reality of psychiatry even more closely than interventionism, but it needs (...) to be supplied with additional heuristics to disambiguate between causes and other difference-makers. To achieve this, I suggest employing heuristics based on multiple experiments, temporal order and scientific domain. (shrink)

In contemporary philosophy there has been a widespread reaction against the cartesian subjective-individualist conception of a person being normative to any understanding of human personality. Looking back to early greek tragedy we find another model such as the objective-participant conception which also dominates the political philosophy of Plato and Aristotle.

It is hypothesized that de Broglie’s ‘matter waves’ provide a dynamical basis for Minkowski spacetime in an antisubstantivalist or relational account. The relativity of simultaneity is seen as an effect of the de Broglie oscillation together with a basic relativity postulate, while the dispersion relation from finite rest mass gives rise to the differentiation of spatial and temporal axes. Thus spacetime is seen as not fundamental, but rather as emergent from the quantum level. A result by Solov’ev which demonstrates that (...) time is not an applicable concept at the quantum level is adduced in support of this claim. Finally, it is noted that de Broglie waves can be seen as the “bridge of becoming” discussed by ( 2005 ). (shrink)

Perspective, Symbol, and Symbolic Form: Concerning the Relationship between Cassirer and Panofsky During the last two decades of the twentieth century, there was a sudden surge of interest in Ernst Cassirer’s major work, The Philosophy of Symbolic Forms (1923–29), and Erwin Panofsky’s essay, ‘Perspective as Symbolic Form’ (1927), an interest that has continued uninterrupted to the present day. Particularly amongst art historians, however, a serious misunderstanding remains evident here – the confusing of ‘symbolic form’ with ‘symbol’. Cultural and perceptual mediations, (...) in which objects (and subjects) are only just in the process of forming, are carelessly turned into arbitrary, isolated objects of art history or pictorial history. Every work, in this view, is regarded as a ‘symbolic form’ to the extent that a representation of the world is ‘expressed’ in it. This article initially reviews Panofsky’s essay in order to establish the context in which the art historian uses the term ‘symbolic form’. His use of it is then compared with Cassirer’s original understanding of the term. A careful distinction is made between ‘symbol’, ‘symbolic pregnance’, and ‘symbolic form’, and this is followed by an analysis of scattered remarks in Cassirer’s writings, and particularly in his posthumous manuscripts and notes, on ‘art’ as symbolic form and on the spatial form that is prior to all perception and art production, as well as his call for a kind of art history that conceives of itself as a scholarly discipline. The article concludes with the recognition that Panofsky not only deliberately, but justifiably – that is, in the spirit of Cassirer, at least – transferred the expression ‘symbolic form’ to ‘perspective’.

Abstract In this article, we investigate the merits of an enactive view of cognition for the contemporary debate about social cognition. If enactivism is to be a genuine alternative to classic cognitivism, it should be able to bridge the “cognitive gap”, i.e. provide us with a convincing account of those higher forms of cognition that have traditionally been the focus of its cognitivist opponents. We show that, when it comes to social cognition, current articulations of enactivism are—despite their celebrated successes (...) in explaining some cases of social interaction—not yet up to the task. This is because they (1) do not pay sufficient attention to the role of offline processing or “decoupling”, and (2) obscure the cognitive gap by overemphasizing the role of phenomenology. We argue that the main challenge for the enactive view will be to acknowledge the importance of both coupled (online) and decoupled (offline) processes for basic and advanced forms of (social) cognition. To meet this challenge, we articulate a dynamic embodied view of cognition. We illustrate the fruitfulness of this approach by recourse to recent findings on false belief understanding.

In lieu of an abstract, here is a brief excerpt of the content:Talking Cures, the Clinic, and the Value of the IneffableDaniel Berthold (bio)KeywordsMadness, disease, the normal, the abnormal, the ineffable, Hegel, Kierkegaard, LacanI am most grateful to my readers, James Phillips and Louis Sass, who have led me to several new insights by suggesting ways of complicating my reading of a Lacanian approach to Hegel's and Kierkegaard's conceptions of madness. I am a Kierkegaard and Hegel scholar, with very (...) little pretense to expertise about Lacan and regrettably even less about the theory and practice of psychiatry. In submitting my essay to Philosophy, Psychiatry, & Philosophy, I was hoping to entice a community of practitioners and theoreticians I have great respect for to consider the musings of a philosopher on topics which engage them as thinkers and actors in their professions. I could not possibly have hoped for more intelligent and provocative replies than I have been given by my two respondents.Phillips' framing of his response in terms of the distinction between the "madness of the philosophers" and the "madness of the clinic" is very helpful. It is a distinction that is indeed central to the question of the possibility of dialogue between philosophers and clinicians—so central, in fact, that it is generous of Phillips not to reproach me for failing to mention it. On the one hand, the challenge for philosophers is to show that their descriptions are not merely metaphoric and that their preoccupation with the dark side of human experience connects in some way with the reality of disease, so that there is some way for clinicians to translate their language into the language of psychiatry. Otherwise, philosophers will have only poetic or literary interest for the psychiatrist or psychologist.On the other hand, the challenge for clinicians is the extent to which they are open to moving beyond a reduction of "mental illness" to a purely biological conception of disease. One needn't go so far—nor should we—as Thomas Szasz or Michel Foucault in seeing "mental disease" as itself merely a metaphor. But granting the evidence of underlying organic disorder, symptoms nevertheless display themselves as mental and behavioral states (what Hegel calls "shapes of consciousness") that, as Hegel argued, are paralleled in "normal" experience, so that the distinction between disease and normality (and hence illness and metaphor) is often elusive. Madness "has the healthy consciousness for its presupposition," Hegel writes, because the healthy mind is still grappling with the same sorts of contradictions and feelings of alienation, the same "infinite pain" which characterizes insanity. Madness is not the absolute "other" of rationality, but an echo of it (1978, 3:382, 408).Hegel himself accepted the medicalization of madness that began to occur in the late eighteenth [End Page 325] century, and rejected the metaphysical and theological categories of what was called "romantic medicine." But he also cautioned against the narrowness of the "somatic" school which he felt lacked sufficient explanatory value if not connected to a "speculative" (i.e., philosophic) framework (see Berthold-Bond 1995, ch. 2).It might even be argued that every person seeking therapy is first of all suffering from "philosophic" madness, at least in the sense that initially she does not understand her own suffering as "disease," but experiences her torment in the vocabulary of the philosopher. Thus the philosopher's descriptions are the closest to the subject's own self-understanding, and while the therapist must seek to rephrase these descriptions into the vocabulary of the clinic (just as Hegel, for example, translated his own philosophic description of the madness of his friend Hölderlin in the Phenomenology as the "lost soul" whose "light dies away within it" into the medical category of Wahnsinn—mania or frenzy, which today we would call schizophrenia—in the classificatory scheme of mental disorder he gives in the Encyclopaedia; 1977, 400; 1978, 408)—there is a real question about which vocabulary is a metaphor for the other.The second main point Phillips addresses, which is taken up in different ways by Sass as well, has to do with the relation between speech and silence in madness. Phillips finds that Kierkegaard offers a more complex and subtle view than... (shrink)

It is suggested that the apparently disparate cosmological phenomena attributed to so-called ‘dark matter’ and ‘dark energy’ arise from the same fundamental physical process: the emergence, from the quantum level, of spacetime itself. This creation of spacetime results in metric expansion around mass points in addition to the usual curvature due to stress-energy sources of the gravitational field. A recent modification of Einstein’s theory of general relativity by Chadwick, Hodgkinson, and McDonald incorporating spacetime expansion around mass points, which accounts well (...) for the observed galactic rotation curves, is adduced in support of the proposal. Recent observational evidence corroborates a prediction of the model that the apparent amount of ‘dark matter’ increases with the age of the universe. In addition, the proposal leads to the same result for the small but nonvanishing cosmological constant, related to ‘dark energy,’ as that of the causet model of Sorkin et al. (shrink)

When Humpty-Dumpty had his great fall nobody could put him together again. A vastly more moderate challenge is to reunite the two partial beams of a Stern-Gerlach apparatus with such precision that the original spin state is recovered. Nevertheless, as we demonstrate, a substantial loss of spin coherence always occurs, unless the experimenter is able to control the magnetic field's inhomogeneity with an accuracy of at least one part in 105.

In Flip Thinking, Berthold Gunster, the founder of the Dutch omdenken--or flip thinking--philosophy, presents fifteen strategies to transform your thinking away from limitations and negativities and towards possibilities and opportunities. From disrupting (turn all the rules upside down) to flaunting (play up what you want to hide) and from importing (get the enemy on board) to amplifying (do more of what works), Gunster's strategies and stories will have you approaching even the most challenging problems--from an annoying neighbor to an (...) angry colleague to an unhappy partner--in a whole new way.

A modified version of Young’s experiment by Shahriar Afshar indirectly reveals the presence of a fully articulated interference pattern prior to the post-selection of a particle in a “which-slit” basis. While this experiment does not constitute a violation of Bohr’s Complementarity Principle as claimed by Afshar, both he and many of his critics incorrectly assume that a commonly used relationship between visibility parameter V and “which-way” parameter K has crucial relevance to his experiment. It is argued here that this relationship (...) does not apply to this experimental situation and that it is wrong to make any use of it in support of claims for or against the bearing of this experiment on Complementarity.

In attempting to derive irreversible macroscopic thermodynamics from reversible microscopic dynamics, Boltzmann inadvertently smuggled in a premise that assumed the very irreversibility he was trying to prove: ‘molecular chaos.’ The program of ‘Einselection’ within Everettian approaches faces a similar ‘Loschmidt’s Paradox’: the universe, according to the Everettian picture, is a closed system obeying only unitary dynamics, and it therefore contains no distinguishable environmental subsystems with the necessary ‘phase randomness’ to effect einselection of a pointer observable. The theoretically unjustified assumption of (...) distinguishable environmental subsystems is the hidden premise that makes the derivation of einselection circular. In effect, it presupposes the ‘emergent’ structures from the beginning. Thus the problem of basis ambiguity remains unsolved in Everettian interpretations. (shrink)

Zusammenfassung Das German Diagnosis Related Groups (G-DRG)-System hat zu einem weitgehend erlösorientierten Krankenhausfinanzierungssystem geführt. Im vorliegenden Beitrag werden die ethischen Implikationen und Folgen dieses Systems am Beispiel rekonstruktiver Maßnahmen (Defektversorgung) bei Patient*innen mit Mundhöhlenkarzinomen herausgearbeitet. Dabei gilt es zugleich, das Wechselspiel von G‑DRG-System und Leitlinienentwicklung zu beleuchten. Vorangestellt werden einführende Angaben zum Mundhöhlenkarzinom und den bestehenden Behandlungsoptionen: konventionelle Rekonstruktionstechnik versus kostenintensive High-End-Chirurgie. Methodische Grundlage und argumentativer Bezugspunkt der Arbeit ist das theoretische Fallszenario „Versorgung mittelgroßer Defekte nach Tumorresektion“. Das G‑DRG-System und (...) die dadurch geschaffenen ökonomischen Anreize haben weitreichende ethische Implikationen in der bedarfsorientierten Behandlung von Patient*innen und führen zu mehrdimensionalen Wechselwirkungen. Die bestehende Tendenz zur High-End-Chirurgie birgt das Risiko der Über- und Fehlversorgung und läuft demnach den Prinzipien Benefizienz und Nonmalefizienz zuwider. Die einseitige Indikationsstellung zugunsten der High-End-Chirurgie lässt zudem auf eine direktive Patientenaufklärung schließen (Verstoß gegen das Prinzip des Respekts der Patientenautonomie). Kostspielige High-End-Verfahren konterkarieren überdies das Wirtschaftlichkeitsgebot und berühren somit zugleich Fragen der Verteilungsgerechtigkeit. Schließlich wirkt die klinische Bevorzugung von High-End-Verfahren auch auf die innermedizinische Logik, namentlich auf die Publikationslandschaft (publication bias), die Ausgestaltung der betreffenden Leitlinien sowie auf die chirurgische Expertise. Zu fordern ist eine Sensibilisierung aller in der Chirurgie tätigen Akteur*innen (Chirurg*innen; Leitlinienexpert*innen, Gutachter*innen). (shrink)

The German term “Antiziganismus” could be translated as “antigypsyism”, but the semantic roots are, in fact, different. Coined in the 1980s, “Antiziganismus” might be misconceived as a sheer abstraction: a “close reading” of the term's context could indeed partially justify the assumption that it in many ways reproduces certain impacts and implications of its better known equivalent – an actively employed anti-Semitism. However, the article's main thesis is that “Antiziganismus” denotes a term in its own right. This status cannot be (...) challenged even by the most recent development, which is an interest group's attempt to internationalize the scope of the term by coining the derivative “antiziganism”.

In lieu of an abstract, here is a brief excerpt of the content:Live or TellDaniel BertholdTwo of the more notoriously elusive authors writing in the first half of the nineteenth century—a century noteworthy on the European continent for producing more than its fair share of elusive authors—are the German idealist Georg Hegel and his posthumous tormentor, the Christian existentialist Søren Kierkegaard. Their elusiveness is such that to read either of them is much like taking a Rorschach test: what we find (...) tells us as much about ourselves as it does about Kierkegaard or Hegel themselves. But to think through the relationship between the two is a yet more challenging task, perhaps like seeking to align the ink-blotted lenses of a Rorshachian kaleidoscope. Some commentators have found no alignment of the lenses to produce anything resembling a meaningful picture, and have concluded, as Niels Thulstrup puts it in his study of Kierkegaard's Relation to Hegel, that, "Hegel and Kierkegaard have in the main nothing in common." 1 With equal forthrightness, Richard Kroner suggests in his essay on "Kierkegaard's Understanding of Hegel" that "Hegel and Kierkegaard are separated from each other by an abyss which no agreement can ever succeed in bridging." 2Such a reading of the Kierkegaard-Hegel relation is in fact made tempting by Kierkegaard's own construction of the relation as one of radical difference. Hegel is the archetypal Other, the perpetual foil whose philosophic values and whole way of thinking and writing Kierkegaard devotes his own authorship to perfectly inverting. If Kierkegaard's Hegel is the philosopher of the "objective spirit" and the champion of reason, more interested in the logical relations between concepts than in the actual reality of existing individuals, Kierkegaard presents himself as the adherent of subjectivity, of faith, of existence.In what follows, I wish to explore one of the most recurring of [End Page 361] Kierkegaard's representations of his difference from Hegel, the contrast between action and thinking about action, existing and contemplating existence, living and philosophizing about living. "In the objective [Hegelian] sense," Kierkegaard's pseudonym Johannes Climacus writes, "thought is understood as being pure thought,... [and] this objective thought has no relation to the existing subject; and while [it is difficult to know] how the existing subject slips into this... pure abstraction,... it is certain that the existing subjectivity tends more and more to evaporate." 3As the contrast gets developed, we will come to focus on Kierkegaard's phrasing of the difference in terms of the role of language. Kierkegaard portrays himself as speaking (writing) in order to act: "to be an author is to act." 4 Hegel, on the other hand, is presented as writing so as to merely speak about acting; hence Hegel is a "mere scribbler" and his philosophy occurs "only on paper" (CUP, p. 176, 375f). In many ways, Kierkegaard understands his contest with Hegel in terms of the ultimatum of the tormented diarist of Jean-Paul Sartre's novella Nausea, Roquentin: "you have to choose: live or tell." 5 Roquentin is doubly cursed, first by a need to write so as to escape his sense of the nausea of existence by distancing himself from the cloying taste of reality, but second, by a recognition that his writing removes him from the possibility of truly existing. His ultimatum, "live or tell," is the constant reminder he carries with him of his inability to reconcile his fear of existence and his self-disgust at his escapism.The contrast between action and thinking leads to a question about the ethics of authorship: how is one to use words, to write, in such a way as to act—and to elicit action from one's reader? I will suggest that a readjustment of Kierkegaard's alignment of the kaleidoscope lenses which display the image of his relation to Hegel allows for a more rewarding dialogue between the two. In this altered image, there is as much telling as living in Kierkegaard as in Hegel (indeed, as we will see, in some respects more so), and as much a choice for living in Hegel as in Kierkegaard. Perhaps most importantly, this reorientation invites us to see the either/or construction of "living... (shrink)

Order and change in nature have been for a long time understood in philosophy and theology as founded in divine reason. In the neo-Darwinist theory of evolution, their explanation is reduced to material change without reason. Molecular biologists like M. Behe and W. Demski argue that any reductionist explanation of living beings must be wrong. The evolution of irreducible complex structures is impossible on the basis of random variation and natural selection alone, and must be the result of intelligent design. (...) The article argues that ID-theory, unlike Biblical Creationism, is a challenge for neo-Darwinism and for modern theology as well—for, unlike the Roman magisterium, many Catholic theologians try to harmonize reductive explanation with the notion of creation.

The article begins by recalling the most important understandings associated with the term prudence in the history of philosophy.Then it introduces the Aristotelian concept of prudence linked to practical truth—prudence seen in contrast to wisdom and knowledge of manufacturing. The article discusses various forms of rational knowledge associated with the right will, and proves the need of linking prudence to all the other ethical virtues based on moral principles. It emphasizes the problem of how to relate general principles to specific (...) actions which involve particular goods. For resolving this problem, the article refers to Aristotle who sees the solution in political ethics which has a significant impact on individual behavior; consequently, good law and proper education are considered to be necessary conditions which allow to form the moral judgment skills for providing a morally good life. The article concludes with the claim that the proper field to capture the specificity of prudence includes the theory of human action and that of human morality. (shrink)

While ideals of racial purity may be out of fashion, other sorts of purity ideals are increasingly popular in the United States today. The theme of purity is noticeable everywhere, but it is especially prominent in our contemporary fixation on health and hygiene. This may seem totally unrelated to issues of racism and classism, but in fact, the purveyors of purity draw upon the same themes of physical and moral purity that have helped produce white identity and dominance in the (...) US. Historically, this is where the purity rhetoric gets its power. To invoke purity ideals in the US is to mobilize this genealogy of racialized associations. Today's zealous preoccupation with hygiene is part of our living heritage in a racist culture.Just as ideas of race and racial purity were debunked by biologists long before the public would begin to question them, ideals of extreme hygienic purity linger with us, even flourish, despite scientific evidence of their futility and harm. Why are we still so enamored with purity? Because, to some extent, our very self-conceptions are at stake. Other scholars have described how our process of self individuation is based upon exclusion. The unique contribution of a genealogical approach to this issue is that, instead of merely locating the problem in ideologies held by others, it can evoke self-recognition and self-transformation. We will tend to assume the problem lies elsewhere until we learn to recognize ourselves in practices that reproduce cultural ideals. As inheritors of this racist culture, we are all lovers of purity, and we are all responsible for rethinking this value. (shrink)

Statistical learning is often taken to lie at the heart of many cognitive tasks, including the acquisition of language. One particular task in which probabilistic models have achieved considerable success is the segmentation of speech into words. However, these models have mostly been tested against English data, and as a result little is known about how a statistical learning mechanism copes with input regularities that arise from the structural properties of different languages. This study focuses on statistical word segmentation in (...) Arabic, a Semitic language in which words are built around consonantal roots. We hypothesize that segmentation in such languages is facilitated by tracking consonant distributions independently from intervening vowels. Previous studies have shown that human learners can track consonant probabilities across intervening vowels in artificial languages, but it is unknown to what extent this ability would be beneficial in the segmentation of natural language. We assessed the performance of a Bayesian segmentation model on English and Arabic, comparing consonant-only representations with full representations. In addition, we examined to what extent structurally different proto-lexicons reflect adult language. The results suggest that for a child learning a Semitic language, separating consonants from vowels is beneficial for segmentation. These findings indicate that probabilistic models require appropriate linguistic representations in order to effectively meet the challenges of language acquisition. (shrink)

Tim Maudlin's argument for the inconsistency of Cramer's Transactional Interpretation of quantum theory has been considered in some detail by Joseph Berkovitz, who has provided a possible solution to this challenge at the cost of a significant empirical lacuna on the part of TI. The present paper proposes an alternative solution in which Maudlin's charge of inconsistency is evaded but at no cost of empirical content on the part of TI. However, Maudlin's argument is taken as ruling out Cramer's heuristic (...) "pseudotime" explanation of the realization of one transaction out of many. (shrink)

In this paper we investigate with a case study from chemistry under what conditions a simulation can serve as a surrogate for an experiment. The case-study concerns a simulation of H2-formation in outer space. We find that in this case the simulation can act as a surrogate for an experiment, because there exists comprehensive theoretical background knowledge in form of quantum mechanics about the range of phenomena to which the investigated process belongs and because any particular modelling assumptions as can (...) be justified. If these requirements are met then direct empirical validation may even be dispensable. We conjecture that this is not the case in the absence of comprehensive theoretical background knowledge.

It is argued that if the non-unitary measurement transition, as codified by Von Neumann, is a real physical process, then the ‘probability assumption’ needed to derive the Second Law of Thermodynamics naturally enters at that point. The existence of a real, indeterministic physical process underlying the measurement transition would therefore provide an ontological basis for Boltzmann’s Stosszahlansatz and thereby explain the unidirectional increase of entropy against a backdrop of otherwise time-reversible laws. It is noted that the Transactional Interpretation of quantum (...) mechanics provides such a physical account of the non-unitary measurement transition, and TI is brought to bear in finding a physically complete, non-ad hoc grounding for the Second Law.

A modified version of Young's experiment by Shahriar Afshar demonstrates that, prior to a ``which-way'' measurement indicating which slit a particle goes through, an interference pattern exists. It has been claimed that this result constitutes a violation of the Principle of Complementarity. This paper discusses the implications of this experiment and considers how Cramer's Transactional Interpretation accomodates the result. It is shown that the Afshar experiment is isomorphic in key respects to a a spin one-half particle prepared as ``spin up (...) along x'' and post-selected in a specific state of spin along z. It is concluded that Bohr would have had no more problem accounting for the Afshar result than he would in accounting for the aforementioned pre- and post-selection spin experiment, in which the particle's preparation state is confirmed by a nondestructive measurement prior to post-selection.
