In his book Knowledge and Practical Interests Jason Stanley offers an argument for the conclusion that it is quite unlikely that an ambiguity theory of ‘knows’ can be “linguistically grounded”. His argument rests on two important assumptions: that linguistic grounding of ambiguity requires evidence of the purported different senses of a word being represented by different words in other languages and that such evidence is lacking in the case of ‘knows’. In this paper, I challenge the conclusion that there isn’t (...) a linguistic grounding for an ambiguity theory of ‘knows’ by making cases against both of Stanley’s major assumptions. I will do this by making a case for a prime facie linguistic grounding for a polysemy theory of ‘knows’ without appealing to word use in other languages. Given that a polysemy theory of ‘knows’ is a type of ambiguity theory of ‘knows’, if I succeed in linguistically grounding a polysemy theory of ‘knows’, then I have shown that at least one type of ambiguity theory of ‘knows’ can be linguistically grounded.

The ambiguity theory of “knows” is the view that knows and its cognates have more than one propositional sense—i.e., more than one sense that can properly be used in “knows that” etc. constructions. The ambiguity theory of “know” has received relatively little attention as an account of the truth-conditions for knowledge ascriptions and denials—especially compared to views like classical, moderate invariantism and epistemic contextualism. In this paper, it is argued that the ambiguity theory of knows has an advantage over both (...) classical, moderate invariantism and epistemic contextualism. This advantage is that it is the only one of these views that can account for “diverging knowledge responses without inconsistency” —i.e., cases in which, for the same subject S and proposition p, one and the same speaker says truly “S knows p” but instead could have truly said “S does not know p” and vice versa. This paper argues both for the existence of DRWI scenarios and the ability of the ambiguity theory of knows to best explain their existence. (shrink)

This essay answers the “Bayesian Challenge,” which is an argument offered by Bayesians that concludes that belief is not relevant to rational action. Patrick Maher and Mark Kaplan argued that this is so because there is no satisfactory way of making sense of how it would matter. The two ways considered so far, acting as if a belief is true and acting as if a belief has a probability over a threshold, do not work. Contrary to Maher and Kaplan, (...) Keith Frankish argued that there is a way to make sense of how belief matters by introducing a dual process theory of mind in which decisions are made at the conscious level using premising policies . I argue that Bayesian decision theory alone shows that it is sometimes rational to base decisions on beliefs; we do not need a dual process theory of mind to solve the Bayesian Challenge. This point is made clearer when we consider decision levels : acting as if a belief is true is sometimes rational at higher decision levels. (shrink)

The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one sense, and that which sense of ‘knows’ is used in a knowledge ascription or denial determines, in part, the meaning (and as a result the truth conditions) of that knowledge ascription or denial. In this paper, I argue that the ambiguity theory of ‘knows’ ought to be taken seriously by those drawn to epistemic contextualism. In doing so I first argue that the ambiguity (...) theory of ‘knows’ is a distinct view from epistemic contextualism. Second, I provide independent philosophical and linguistic considerations to motivate the ambiguity theory. Third, I argue that the ambiguity theory has the same central, generally agreed upon virtues ascribed to epistemic contextualism (namely, the ability to solve certain persistent epistemological problems relating to skeptical arguments and the ability to preserve the truth of most of our everyday, ordinary usages of ‘knows’ and its cognates). Finally, I provide an ambiguity-theory-friendly account of why contextualism may be initially appealing, and why this shouldn’t dissuade us from taking the ambiguity theory seriously nonetheless.

The ambiguity theory of ‘knows’ is the view that ‘knows’ and its cognates have more than one propositional sense – i.e. more than one sense that can properly be used in ‘knows that’ etc. constructions. Given that most of us are ‘intuitive invariantists’ – i.e. most of us initially have the intuition that ‘knows’ is univocal – defenders of the ambiguity theory need to offer an explanation for the semantic blindness present if ‘knows’ is in fact ambiguous. This paper is (...) an attempt to offer such an explanation. Section 1 contains a general argument for the ubiquity of semantic blindness for ambiguous words; the upshot being that semantic blindness for the ambiguity of ‘knows’ is thus unsurprising. Section 2 offers more specific arguments for why ‘knows’ is the type of ambiguous word that we’re very unlikely to quickly recognize is ambiguous. (shrink)

Moral theories usually aspire to be explanatory – to tell us why something is wrong, why it is good, or why you ought to do it. So it is worth knowing how moral explanations differ, if they do, from explanations of other things. This paper uncovers a common unarticulated theory about how normative explanations must work – that they must follow what I call the Standard Model. Though the Standard Model Theory has many implications, in this paper I focus primarily (...) on only one. It plays a crucial role in an argument originally due to Cudworth that has been widely held to conclusively establish that voluntaristic ethical theories are incoherent. But if Cudworth’s argument works, then so would similar arguments against many other moral theories. All of these theories therefore need a different model for how normative explanations can work. So I also motivate and sketch one such alternative model. The result enables us to make progress in evaluating the prospects for a successful reductive view about the normative. (shrink)

According to the thesis of the guise of the normative, all desires are associated with normative appearances or judgments. But guise of the normative theories differ sharply over the content of the normative representation, with the two main versions being the guise of reasons and the guise of the good. Chapter 6 defends the comparative thesis that the guise of reasons thesis is more promising than the guise of the good. The central idea is that observations from the theory of (...) content determination can be used in order to constrain possible theories of the representational contents associated with desire. The authors argue that the initially most promising versions of the guise of the good fail to meet these constraints, and then explain the steep challenge confronting any who wish to craft a new guise of the good theory which meets the constraints while also preserving the initial motivations for adopting any guise of the normative theory at all. But a simple version of the guise of reasons not only avoids the troubles besetting the guise of the good but proceeds immediately from a deep diagnosis of the source of its difficulties. (shrink)

Physicists Brian Greene and Max Tegmark both make variants of the claim that if the universe is infinite and matter is roughly uniformly distributed, then there are infinitely many “people with the same appearance, name and memories as you, who play out every possible permutation of your life choices.” In this paper I argue that--while our current best theories in astrophysics may allow one to conclude that we have infinitely many duplicates whose lives are identical to our own from start (...) to finish--without either further advances in physics or advances in fields like biology, psychology, neuroscience, and philosophy, Greene’s and Tegmark’s claims about the ways in which our duplicates lives will differ from our own are not a consequence of our best current scientific theories. Rather, I argue that Greene and Tegmark’s conclusions rely on philosophically imprecise usages of the language of “possibility.”. (shrink)

This article considers two important problems for the idea that what we ought to do is determined by the balance of competing reasons. The problems are distinct, but the object of the article is to explore how they admit of a single solution. It is a consequence of this solution that objective reasons—facts that count in favor—are in an important sense less objective than they have consistently been assumed to be. This raises but does not answer the question as to (...) what evidence we ever had that reasons are as objective as has been assumed. (shrink)

The concept of a reason is now central to many areas of contemporary philosophy. Key theses in ethics, epistemology, political philosophy, philosophy of action, and the philosophy of the emotions, among others, have come to be framed in terms of reasons. And yet, despite their centrality, theorists seem to take inconsistent things for granted about how reasons work, what kinds of things can be reasons, what reasons favor, and more. Somehow reasons have come to be both indispensable and impenetrable. -/- (...) The Fundamentals of Reasons offers a comprehensive introduction to the philosophy of reasons. Focusing on the twin roles of reasons in explanation and deliberation, the book not only emphasizes what has made reasons central across philosophy but it also explores why philosophers have such incompatible pictures about what reasons are and how they work. Working from the inside out, Howard and Schroeder identify contentious assumptions about not only the internal structure of reasons but also their relationship to other important concepts, and then show how these contentious assumptions shape the many downstream applications of reasons in ethics, epistemology, political philosophy, and beyond. -/- This mildly opinionated exploration of key questions about the significance and nature of reasons helps the reader to navigate this important part of the philosophical landscape and to get clearer about why reasons seem important and what their import, ultimately, is.

Self-representational theories of consciousness hold that a mental phenomenon is conscious if, and only if, it presents, among other things, itself. But in conscious perception one may lose oneself in the object perceived and not be aware of one’s perceiving. The paper develops a Brentano-inspired response to this objection. He follows Aristotle in holding that one is aware of one’s perceiving only ‘on the side’: when one perceives something one’s perception neither is nor can become observation of itself. I argue (...) that the arguments Brentano gave for this claim in Psychology from an Empirical Standpoint are wanting. However, a promising argument emerges if one takes Brentano’s conception of noticing into account. (shrink)

People sometimes use speech to interfere with other people’s speech, as in the case of a heckler sabotaging a lecture with constant interjections. Some people claim that such interference infringes upon free speech. Against this view, we argue that where competing speakers in a public forum both have an interest in speaking, free speech principles should not automatically give priority to the ‘official’ speaker. Given the ideals underlying free speech, heckling speech sometimes deserves priority. But what can we say, then, (...) about situations in which heckling clearly seems to infringe upon people’s civil liberties, in a way that intuitively justifies intervention? In such cases, we argue, heckling infringes upon people’s associative freedom. We present and defend an ethical framework for the institutional management of ‘Speech Fights’, geared around this insight. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Remembering Richard J. Bernstein (1932–2022)Tara Mastrelli and Mark SandersRemembrance for Richard J. BernsteinMy name is Tara Mastrelli. I am a graduate student at the New School for Social Research.1 Dick Bernstein was my teacher and my friend. I was also the TA for his final seminar on American Pragmatism this past spring, an experience that I want to share with you today.In the months leading up to this (...) seminar, Dick said something shifted for him in the way he understood pragmatism—a sort of awakening on his part. He redesigned his syllabus into two parts—the first, working through the classical pragmatists, namely, Peirce, James, and Dewey, as he had done for sixty-eight years. And then the second half would—in Dewey's words—turn toward "the problems of men" (though Dick would always say human beings), engaging with themes and texts from Black and feminist thinkers. To be clear, for Dick, this was not an expansion of the canon or an exercise in who should or should not count as a pragmatist. Rather his aim was something different altogether—to see if we could begin to understand pragmatism not as a canon at all, but rather as a living, evolving movement.Now the point is not that this was the perfect syllabus—it wasn't. The point is what redesigning his syllabus can tell us about the type of person and teacher that Dick was. At almost 90 years old, teaching a subject he had taught for almost seventy years, he did not sit back and say that he knew everything. He wanted to learn more—from his colleagues, his students, the world around him—to experience more, to challenge his assumptions, to understand more. [End Page 103]Beyond the syllabus, another factor that made this seminar unique was Dick's health. His illness started at the beginning of the semester. He taught our first class from an emergency room in New York City during the Omicron wave of COVID-19. He was wearing a mask and breathing tubes. Machines were beeping all around him. Nurses came in from time to time to check on him. Nonetheless … his enthusiasm was not remotely diminished. Laying out his aims and ambitions for the course, he referred to it as "an exciting adventure"—for him and for us.The syllabus was not perfect, and Dick's health ebbed and flowed throughout, and yet—as the course itself progressed—it evolved into the very thing he was hoping for, which was pragmatism as a living, evolving movement. He read and added new work from a colleague examining Black feminist pragmatism and its relationship to the Movement for Black Lives, adding a full session dedicated to it. On certain days, when his breath was weak, he asked me to lead our discussions, which took on more of an almost jazz-like character—my classmates and I riffing off each other as we tried to wrestle with concepts such as DuBois's color line against the backdrop of gentrification in our own neighborhoods. When I decided to run a progressive stack for our discussions on feminism, Dick replied, "Good for you!" and enthusiastically used the hand-raising function, patiently waiting his turn.At the end of the semester, he seemed to be feeling better—his voice was strong and his eyes were bright during our final session. He conveyed his sense that, despite his recurring lament that we did not have more time (he had always envisioned the course as two semesters, or sometimes two full years), the seminar had achieved what he had wanted to achieve: "Philosophy has come alive." A return to philosophy, "not just as a discipline to master, but something to be caught up in; the excitement of dealing with life—a return to a genuine Socratic conception of philosophy."I am sure many of you may know that Dick wrote his dissertation on Dewey. What you may not know is that he originally wanted to write it on Plato. (Phaedrus was his favorite.) But once he sat down, he realized he did not want to write something about Plato that, as he said... (shrink)

I propose a definition of the uncanny: an anxious uncertainty about what is real caused by an apparent impossibility. First, I outline the relevance of the uncanny to art and aesthetics. Second, I disambiguate theoretical uses of ‘uncanny’ and establish the sense of the term that I am interested in—namely, an emotional state directed towards particular objects in the world which are characteristically eerie, creepy, and weird. Third, I look at Edgar Allan Poe’s ‘The Fall of the House of Usher’ (...) as a means of drawing out the conditions that I claim are essential to uncanny experiences, and then elaborate the terms of my proposed definition. Finally, I show how the definition accounts for two paradigmatic kinds of uncanny phenomena: cases of ‘uncanny resemblances’, which include twins, doppelgangers, and very lifelike representations of the human body; and unlikely coincidences of events.

Moritz Schlick’s work shaped Logical Empiricism and thereby an important part of philosophy in the first half of the 20th century. A continuous thread that runs through his work is a philosophical diagnosis of the ‘great errors in philosophy’: philosophers assume that there is intuitive knowledge/knowledge by acquaintance. Yet acquaintance, it is not knowledge, but an evaluative attitude. In this paper I will reconstruct Schlick’s arguments for this conclusion in the light of his early practical philosophy and his reading of (...) Schopenhauer’s The World as Will and Idea. Having the historical roots of Schlick’s position in view will put us in a position to explore and question its presuppositions. (shrink)

Contrary to many interpreters, I argue that Thomas Aquinas’s account of divine simplicity is compatible with the accounts of divine simplicity given by John Duns Scotus and Gregory Palamas. I synthesize their accounts of divine simplicity in a way that can answer the standard objections to the doctrine of divine simplicity more effectively than any of their individual accounts can. The three objections that I consider here are these: the doctrine of divine simplicity is inconsistent with distinguishing divine attributes, with (...) the doctrine of the Trinity, and with the doctrine of divine freedom.

There is a growing body of literature that has sought to undermine systems of ethical regulation, and governance more generally, within the social sciences. In this paper, we argue that any general claim for a system of research ethics governance in social research depends on clarifying the nature of the stake that society has in research. We show that certain accounts of this stake—protecting researchers’ freedoms; ensuring accountability for resources; safeguarding welfare; and supporting democracy—raise relevant ethical considerations that are reasonably (...) contested. However, these accounts cannot underpin a general claim in favour of, or against, a system of research ethics governance. Instead, we defend governance in social research on the grounds that research, as an institutionalised form of enquiry, is a constitutive element of human flourishing, and that society ought to be concerned with the flourishing of its members. We conclude by considering the governance arrangements that follow from, and are justified by, our arguments. (shrink)

This chapter argues for an interpretation of Kant's psychology of moral evil that accommodates the so-called excluded middle cases and allows for variations in the magnitude of evil. The strategy involves distinguishing Kant's transcendental psychology from his empirical psychology and arguing that Kant's character rigorism is restricted to the transcendental level. The chapter also explains how Kant's theory of moral evil accommodates 'the badass'; someone who does evil for evil's sake.

My aim in this chapter is to extend the Realist account of the foundations of linguistics offered by Postal, Katz and others. I first argue against the idea that naive Platonism can capture the necessary requirements on what I call a ‘mixed realist’ view of linguistics, which takes aspects of Platonism, Nominalism and Mentalism into consideration. I then advocate three desiderata for an appropriate ‘mixed realist’ account of linguistic ontology and foundations, namely (1) linguistic creativity and infinity, (2) linguistics as (...) a theory of types (and not tokens) and (3) independence but structural respect between language and the linguistic competence thereof. My own brand of mixed realism, what I call ante rem realism, is defended along the lines of an ante rem or non-eliminative structuralism, the likes of which has been offered for mathematics by Resnik (1997) and Shapiro (1997). In other words, grammars describe a mind-independent (but not necessarily unconnected) linguistic reality in terms of linguistic patterns or structures also known as natural languages. I further amend this picture to allow for the possibility of a naturalistic account of language acquisition and evolution by arguing against a particular view of the type-token distinction. (shrink)

This chapter defends the claim that the space of human actions is really partitionable into five non-overlapping deontic categories: the three commonly recognized ones (the obligatory, the impermissible or wrong, and the optional), plus two additional ones labeled the expected and the contra-expected. These latter categories are typically not recognized in ethical theorizing but nonetheless they are part of everyday moral experience. The defense of these additional deontic categories appeals, via inference to the best explanation, partly to phenomenological considerations and (...) partly to moral-normative considerations. It is further argued that this five-way partition of the deontic realm helps explain why the hybrid categories of the supererogatory and suberogatory are deontically asymmetrical. (shrink)

The debate on probabilistic measures of coherence has focused on evaluating sets of consistent propositions. In this paper we draw attention to the largely neglected question of whether such measures concur with intuitions on test cases involving inconsistent propositions and whether they satisfy general adequacy constraints on coherence and inconsistency. While it turns out that, for the vast majority of measures in their original shape, this question must be answered in the negative, we show that it is possible to adapt (...) many of them in order to improve their performance.

Do pregnant mothers have fetuses as parts? According to the “parthood view” they do, while according to the “containment view” they don’t. This paper raises a novel puzzle about pregnancy: if mothers have their fetuses as parts, then wherever there is a pregnant mother, there is also a smaller thinking being that has every part of the mother except for those that overlap with the fetus. This problem resembles a familiar overpopulation puzzle from the personal identity literature, known as the (...) “Thinking Parts Problem”, but it’s not merely a special case of that problem. Rather, the fact that late-term fetuses have a mental life of their own makes the Problem of Pregnant Thinkers, as I will call it, a sui generis and especially recalcitrant problem. (shrink)

“Scientific research faces up with an open and unknown world”Within the work of C. S. Peirce, the most fundamental and contentious form of inference is that of abduction. According to Peirce, abduction is the only type of inference from which new ideas are created (CP 5.171, 1903). He wrote, “every single item of scientific theory which stands established today has been due to Abduction” (CP 5.172, 1903). Similarly, “All that makes knowledge applicable comes to us viâ abduction. […] Not the (...) smallest advance can be made in knowledge beyond the stage of vacant staring, without making an abduction at every step” (HP 2:899–900, 1901). It is little wonder that so much attention has been paid to this particular type of.. (shrink)

The Actual and the Possible presents new essays by leading specialists on modality and the metaphysics of modality in the history of modern philosophy from the seventeenth to the twentieth centuries. It revisits key moments in the history of modern modal doctrines, and illuminates lesser-knownmoments of that history. The ultimate purpose of this historical approach is to contextualise and even to offer some alternatives to dominant positions within the contemporary philosophy of modality. Hence the volume contains not only new scholarship (...) on the early-modern doctrines of Baruch Spinoza,G. W. F. Leibniz, Christian Wolff and Immanuel Kant, but also work relating to less familiar nineteenth-century thinkers such as Alexius Meinong and Jan Lukasiewicz, together with essays on celebrated nineteenth- and twentieth-century thinkers such as G. W. F. Hegel, Martin Heidegger and BertrandRussell, whose modal doctrines have not previously garnered the attention they deserve. The volume thus covers a variety of traditions, and its historical range extends to the end of the twentieth century, addressing the legacy of W. V. Quine's critique of modality within recent analyticphilosophy. (shrink)

Although an important part of the origins of analytic philosophy can be traced back to philosophy in Austria in the first part of the twentieth century, remarkably little is known about the specific contribution made by Austrian philosophy and philosophers. In The Austrian Contribution to Analytic Philosophy , prominent analytic philosophers take a fresh look at the roots of analytic philosophy in the thought of influential but often overlooked Austrian philosophers including Brentano, Meinong, Bolzano, Husserl, and Witasek. The contributors to (...) this volume investigate central topics in theoretical philosophy such as intentionality, consciousness, memory, attributes, and truth as well as political philosophy and aesthetics. This original collection will be of interest to anyone studying the origins of analytic philosophy as well as contemporary debates in philosophy of language, metaphysics and mind. (shrink)

Die individuellen und gesellschaftlichen Folgen des demographischen Wandels rücken moralische Fragen, die den angemessenen Umgang mit älteren Menschen und die sinnvolle Gestaltung des Lebens im Alter betreffen, verstärkt in den Mittelpunkt öffentlicher Aufmerksamkeit sowie medizin- bzw. pflegeethischer und gesundheitspolitischer Auseinandersetzungen. Allerdings wird das Altern als Prozess und das höhere Alter als Lebensphase in vielen dieser medizin- bzw. pflegeethischen und gesundheitspolitischen Debatten zumeist lediglich unter dem spezifischen Gesichtspunkt der jeweils erörterten Praktiken, Fragestellungen und Problemlagen thematisiert. Eine Betrachtung, die diese verschiedenen konkreten (...) Praxis- und Diskussionskontexte übergreift, das in ihnen jeweils vorausgesetzte Verständnis des Alter(n)s als solches thematisiert und in seiner Bedeutung für die ethische Fachdiskussion grundsätzlich reflektiert, findet dagegen kaum statt. Die Arbeitsgruppe „Altern und Ethik“ in der Akademie für Ethik in der Medizin soll zur Entwicklung einer solchen grundlegenderen und umfassenderen Betrachtungsweise beitragen. Der vorliegende Beitrag gibt einen ersten orientierenden Überblick über die zentralen Themenschwerpunkte, Problemstellungen und Kontroversen in den aktuellen medizin- bzw. pflegeethischen und gesundheitspolitischen Diskursen um das Alter(n) und markiert offene Fragen und Forschungsdesiderate. Wie sich dabei zeigt, kann eine eingehendere Auseinandersetzung mit dem Alter(n) nicht nur den einschlägigen alter(n)sbezogenen Fachdebatten zu fundierteren Perspektiven verhelfen, sondern auch der ethischen Diskussion insgesamt wichtige Impulse im Hinblick auf ihre anthropologischen Grundlagen und ihren normativen Bezugsrahmen vermitteln.

In an earlier paper, Mark Spencer synthesized three understandings of divine simplicity, arguing that the Thomist account can be enriched by Scotist and Palamite distinctions. After summarizing that earlier work, this paper builds upon it in four main ways. Firstly, it relates Scotus’ logical (diminished) univocity to Aquinas’ metaphysical analogy in language about God. Secondly, it explores the limits of univocity and the formal distinction as applied to the divine essence (in the Palamite sense), utilising the scientific metaphor of (...) tomography. Thirdly, it defends Palamite energies from the charge of being Thomistic accidents by introducing the concept of “intrinsic ramification” and applying that concept to the Thomistic divine ideas. Fourthly, it tabulates some significant pre-existing parallels between the three systems’ nomenclature in referring to similar aspects of the divine. (shrink)

To have a propositional attitude, a thinker must possess the concepts included in its content. Surprisingly, this rather trivial principle refl ects badly on many theories of concept possession because, in its light, they seem to require too much. To solve this problem, I point out an ambiguity in attributions of the form 'S possesses the concept of Fs'. There is an undemanding sense which is involved in the given principle, whereas the theoretical claims concern a stronger sense which can (...) be brought out by formulations such as 'S has an adequate conception of Fs' or 'S knows what Fs are'.

Current work on first-person thought takes its distinctive feature to be epistemological. First-person thinking is non-observational and immune to errors to which other varieties of thought about us are open. In contrast, the nineteenth century philosopher Hermann Lotze (1817-81) put the distinctive concern we have for the object of first-person thought at the center of his account. His arguments suggest that first-person thought is essentially evaluative. In this paper I will reconstruct and defend the core of Lotze’s view of self-consciousness.

When we assume that we have cultural competence rather than thoroughly engaging in what Dewey calls the pattern of inquiry, we fail to achieve cultural humility. By analyzing how habits undermine inquiry and underlie failure in situations that call for cultural humility, we may be better equipped to address unintentional offenses. In this essay, I define cultural humility and contrast it with cultural competence, explaining why aiming for cultural competence alone is problematic. Next, I consider the attributes necessary for cultural (...) humility and the attitudes that Dewey considers beneficial for inquiry. This is followed by an outline of Dewey’s pattern of inquiry and explanation of how unquestioned habits of thought short-circuit our ability to become culturally humble. I suggest that we forgo attempting to achieve cultural competence and instead use Dewey’s pattern of inquiry with the attitudes he recommends as tools to work toward cultural humility. (shrink)

One problem facing Hockney and Falco is the lack of evidence among optical sources to support their claim that artists used image-projection by the early 1400s. After all, if quattrocento artists knew about image-projection, they must have learned about it from experts in the field, and no one was more expert at the time than Perspectivist opticians. As I argue in this paper, however, Perspectivist reflection-analysis posed certain theoretical and conceptual constraints that would have prevented Perspectivist opticians from recognizing, much (...) less understanding, image-projection. Their silence on this matter is therefore not evidence against the Hockney-Falco thesis. (shrink)
