Prawitz conjectured that the proof-theoretically valid logic is intuitionistic logic. Recent work on proof-theoretic validity has disproven this. In fact, it has been shown that proof-theoretic validity is not even closed under substitution. In this paper, we make a minor modification to the definition of proof-theoretic validity found in Prawitz’s 1973paper ‘Towards a foundation of a general proof theory’ and refined by Schroeder-Heister in ‘Validity concepts in proof-theoretic semantics’ (2006). We will call the new notion generalized proof-theoretic validity and (...) show that the logic of generalized proof-theoretic validity is intuitionistic logic. (shrink)

Prawitz conjectured that proof-theoretic validity offers a semantics for intuitionistic logic. This conjecture has recently been proven false by Piecha and Schroeder-Heister. This article resolves one of the questions left open by this recent result by showing the extensional alignment of proof-theoretic validity and general inquisitive logic. General inquisitive logic is a generalisation of inquisitive semantics, a uniform semantics for questions and assertions. The paper further defines a notion of quasi-proof-theoretic validity by restricting proof-theoretic validity to allow double negation elimination (...) for atomic formulas and proves the extensional alignment of quasi-proof-theoretic validity and inquisitive logic.

The interplay of philosophical ambitions and technical reality have given birth to rich and interesting approaches to explain the oft-claimed special character of mathematical and logical knowledge. Two projects stand out both for their audacity and their innovativeness. These are logicism and proof-theoretic semantics. This dissertation contains three chapters exploring the limits of these two projects. In both cases I find the formal results offer a mixed blessing to the philosophical projects. Chapter 1. Is a logicist bound to the claim (...) that as a matter of analytic truth there is an actual infinity of objects? If Hume’s Principle is analytic then in the standard setting the answer appears to be yes. Hodes’s work pointed to a way out by offering a modal picture in which only a potential infinity was posited. However, this project was abandoned due to apparent failures of cross-world predication. I re-explore this idea and discover that in the setting of the potential infinite one can interpret first-order Peano arithmetic, but not second-order Peano arithmetic. I conclude that in order for the logicist to weaken the metaphysically loaded claim of necessary actual infinities, they must also weaken the mathematics they recover. Chapter 2. There have been several recent results bringing into focus the super-intuitionistic nature of most notions of proof-theoretic validity. But there has been very little work evaluating the consequences of these results. In this chapter, I explore the question of whether these results undermine the claim that proof-theoretic validity shows us which inferences follow from the meaning of the connectives when defined by their introduction rules. It is argued that the super-intuitionistic inferences are valid due to the correspondence between the treatment of the atomic formulas and more complex formulas. And so the goals of proof-theoretic validity are not undermined. Chapter 3. Prawitz (1971) conjectured that proof-theoretic validity offers a semantics for intuitionistic logic. This conjecture has recently been proven false by Piecha and Schroeder-Heister (2019). This chapter resolves one of the questions left open by this recent result by showing the extensional alignment of proof-theoretic validity and general inquisitive logic. General inquisitive logic is a generalisation of inquisitive semantics, a uniform semantics for questions and assertions. The chapter further defines a notion of quasi-proof-theoretic validity by restricting proof-theoretic validity to allow double negation elimination for atomic formulas and proves the extensional alignment of quasi-proof-theoretic validity and inquisitive logic.Abstract prepared by Will Stafford extracted partially from the dissertation.

Proof-theoretic validity has proven a useful tool for proof-theoretic semantics, because it explains the harmony found in the introduction and elimination rules for the intuitionistic calculus. However, the demonstration that a rule of proof is proof-theoretically valid requires checking an infinite number of cases, which raises the question of whether proof-theoretic validity is decidable. It is proven here that it is for the most prominent formulations in the literature for propositional logic.

An account of mathematical understanding should account for the differences between theorems whose proofs are “easy” to discover, and those whose proofs are difficult to discover. Though Hilbert seems to have created proof theory with the idea that it would address this kind of “discovermental complexity”, much more attention has been paid to the lengths of proofs, a measure of the difficulty of _verifying_ of a _given_ formal object that it is a proof of a given formula in a given (...) formal system. In this paper we will shift attention back to discovermental complexity, by addressing a “topological” measure of proof complexity recently highlighted by Alessandra Carbone ( 2009 ). Though we will contend that Carbone’s measure fails as a measure of discovermental complexity, it forefronts numerous important formal and epistemological issues that we will discuss, including the structure of proofs and the question of whether impure proofs are systematically simpler than pure proofs.

Research programs in empirical psychology over the past few decades have led scholars to posit implicit biases. This is due to the development of innovative behavioural measures that have revealed aspects of our cognitions which may not be identified on self-report measures requiring individuals to reflect on and report their attitudes and beliefs. But what does it mean to characterise such biases as implicit? Can we satisfactorily articulate the grounds for identifying them as bias? And crucially, what sorts of cognitions (...) are in fact being measured; what mental states or processes underpin such behavioural responses? In this paper, we outline some of the philosophical and empirical issues engaged when attempting to address these three questions. Our aim is to provide a constructive taxonomy of the issues, and how they interrelate. As we will see, any view about what implicit bias is may depend on a range of prior theoretical choices.

Clear, concise and authoritative, Professor Stafford summarises and discusses five key works of one of England's greatest nineteenth-century thinkers: Mill's autobiography, Considerations on representative government, On liberty, The subjection of women and utilitarianism. Every year students of a variety of disciplines, political thought, history, literature, must rapidly acquire a basic understanding of some of Mill's principal ideas, their historical importance and continuing significance. This original work will be an invaluable companion.

The paper will show that on women and the family his writings exhibit a contradictory stance between nineteenth-century patriarchalism and progressive ideas; he appears to oscillate, as it were, between Hegel or Ruskin and Engels or J.S. Mill. This seems curious to a late twentieth-century reader, but was by no means eccentric in the context of German feminist and socialist discourse of his time. His philosophy of gender cannot be dismissed as a mere collection of tired patriarchalist cliches; like (...) his philosophy of society it is rich and still worthy of attention. (shrink)

Intellectual virtues are an integral part of adequate environmental virtue ethics; these virtues are distinct from moral virtues. Including intellectual virtues in environmental virtue ethics produces a more fine-grained account of the forces involved in environmental exploration, appreciation, and decision making than has been given to date. Intellectual virtues are character traits that regulate cognitive activity in support of the acquisition and application of knowledge. They are virtues because they further the human quest for knowledge and true belief; possessing these (...) traits improves us epistemically. Five intellectual virtues illustrate the nature and relevance of intellectual virtues to environmental ethics: thoroughness, temporal/structural sensitivity, flexibility, intellectual trust, and humility. While these virtues share many features of the moral virtues, there are differences between them that have practical implications and give sound reasons for considering these two types as distinct kinds. Intellectual virtues bear a structural relation to knowledge that moral virtues do not, and it is this epistemological stamp that sets them apart. Additionally, the two types of virtue can be possessed independently of one another. Ideally, intellectual virtues will combine with moral virtues such as respect, compassion, and humility to facilitate environmentally respectful behavior. The moral and intellectual virtues are thus importantly distinct and mutually reinforcing. Both should be present in a truly excellent human being, and both have a role to play in fully developed environmental virtue ethics. (shrink)

There are now many important contributions to the scientific study of the brain-mind continuum. These results come both from research into non-ordinary states of consciousness and into the brain's intrinsic, largely unconscious mechanisms. The larger potential of such investigations consists precisely in making the parameters of our cognitive system apparent. But they also reveal the socio-cultural uses to which these parameters are currently, or in the foreseeable future, being applied. This article wrestles with that fact. Specifically, it examines the implications (...) for those of us interested in the dynamics of visual awareness and the structural and phenomenological aspects of noticing. Because some of the key characteristics of consciousness are so ingrained that we are usually blind to them, it is all the more important to understand how and why we pay attention to certain features of our environment. Subjective consciousness pertains to the realm of inner experience as well as focusing on the external world. What Daniel Dennett terms `intentionality' or directedness towards an object is a sign of our connectedness to the outside world. Beyond connection, I am interested in how complex works of art help us cognize, confer reality, or have knowledge of what lies before our eyes. I will argue that this calibration of the agent's experience and her perception of the world is under threat today. (shrink)

Piéron's Law describes the relationship between stimulus intensity and reaction time. Previously (Stafford & Gurney, 2004), we have shown that Piéron's Law is a necessary consequence of rise-to-threshold decision making and thus will arise from optimal simple decision-making algorithms (e.g., Bogacz, Brown, Moehlis, Holmes, & Cohen, 2006). Here, we manipulate the color saturation of a Stroop stimulus. Our results show that Piéron's Law holds for color intensity and color-naming reaction time, extending the domain of this law, in line (...) with our suggestion of the generality of the processes that can give rise to Piéron's Law. In addition, we find that Stroop condition does not interact with the effect of color saturation; Stroop interference and facilitation remain constant at all levels of color saturation. An analysis demonstrates that this result cannot be accounted for by single-stage decision-making algorithms which combine all the evidence pertaining to a decision into a common metric. This shows that human decision making is not information-optimal and suggests that the generalization of current models of simple perceptual decision making to more complex decisions is not straightforward.

In this panel six IS researchers from varying backgrounds will discuss whether epistemological anarchy, as proposed by the controversial philosopher Paul Feyerabend, has the potential to foster research progress and can help to create new insights in the IS field. Feyerabend is well known for his notion that "anything goes" in terms of methodology, and many scholars are concerned that this seemingly anarchistic sentiment can undermine efforts to systematically build and structure an epistemological and methodological foundation for an academic (...) discipline. This panel, which will be moderated by Horst Treiblmaier, includes as panelists Andrew Burton-Jones, Shirley Gregor, Rudy Hirschheim, Michael Myers, and Tom Stafford. The outcome of this discussion will be incorporated into a paper published in the DATA BASE for Advances in Information Systems. (shrink)

The history of British cybernetics offers us a different form of science and engineering, one that does not seek to dominate nature through knowledge. I want to say that one can distinguish two different paradigms in the history of science and technology: the one that Heidegger despised, which we could call the Modern paradigm, and another, cybernetic, nonModern, paradigm that he might have approved of. This essay focusses on work in the 1950s and early 1960s by two of Britain’s leading (...) cyberneticians, Stafford Beer and Gordon Pask, in the field of what one can call biological computing. My object is to get as clear as I can on what Beer and Pask were up to. At the end, I will discuss Beer’s hylozoist ontology of matter, mind and spirit. This material is not easy to get the hang of—but that is what one should expect from an unfamiliar paradigm. (shrink)

This article examines the connecting lines between the Chilean Project Cybersyn’s interface design, the German Hochschule für Gestaltung Ulm and its cybernetically inspired approaches towards information design, and later developments in interaction design and the emerging field of Human–Computer Interaction in the USA. In particular, it first examines how early works of designers Tomàs Maldonado and Gui Bonsiepe on operative communication, that is, language-independent pictogram systems and visual grammars for computational systems, were intertwined with attempts to ground industrial design in (...) a scientific methodology, to address an era of computing machines, and to develop the concept of the interface as a heuristic for a renovated design thinking. It thereby also reconstructs further historical vanishing lines—e.g. the pictorial grammar of Otto Neurath’s ISOTYPE—of the development of the ‘ulm model’ of design. Second, the article explores how an apprehension of first-order cybernetics in West Germany—e.g. represented by hfg ulm staff like Max Bense or Abraham Moles, merged with Cybersyn’s second-order cybernetics ideas, as represented by Stafford Beer’s Viable System Model. And third, it asks about a further conceptual turn regarding an understanding of design which resulted in a focus on communicative interaction, e.g. in the later works of Fernando Flores and Terry Winograd on HCI, or in Beer’s Team Syntegrity approach. As an effect, the text will explore a specific and international network of cybernetic thinking between Latin America, Europe, and North America which emerged around Project Cybersyn, and which was occupied with questions of HCI, a democratization of design, and intelligence amplification.

In 1972, in Chile, the German designer Gui Bonsiepe was in charge of the Industrial Design Department of Technological Institute of the National Corporation for the Promotion of Production INTEC Corfo, during the government of socialist President Salvador Allende in Chile. In this article from the INTEC magazine n.2, published this time for the first time in English, Bonsiepe develops a theoretical formulation, applied to the field of design, through which he proposes a concept that will be fundamental in (...) the field of interactive development, both analog and digital: the Interface. Thus, it also includes concepts of cybernetics such as variability and predictive study of behavior in the field of projecting disciplines. Bonsiepe is an exceptional representative during the formation of the iconic Hochschule für Gestaltung in Ulm. And among other elements, one very outstanding was his time as a student of Professor Max Bense and Horst Rittel, who would have introduced the concepts of first-order Cybernetics in the teaching of communication, and the design of information, in a pioneering way. The challenge posed in 1972, in Chile, focused on the possibility of calculating elements of criticism of political economy, in the field of knowledge generated by sensitive experiences, "calculating the use value" of the field of esthetics. As a renowned disciple of Max Bense and Tomas Maldonado, Bonsiepe represents the meeting of two Cybernetic traditions, collaborating with the emblematic Cybersyn Corfo project, in which the formulation of interaction mechanisms was strategic in combination with Stafford Beer's approaches to a second-order Cybernetics, according to the Viable System Model, for a project of decentralized state production, and transmission of information in real time.

Barbara Stafford is at the forefront of a growing movement that calls for the humanities to confront the brain’s material realities. In Echo Objects she argues that humanists should seize upon the exciting neuroscientific discoveries that are illuminating the underpinnings of cultural objects. In turn, she contends, brain scientists could enrich their investigations of mental activity by incorporating phenomenological considerations—particularly the intricate ways that images focus intentional behavior and allow us to feel thought. This, then, is a book for (...) both sides of the aisle, a stunningly broad exploration of how complex images—or patterns that compress space and time—make visible the invisible ordering of human consciousness. Stafford demonstrates, for example, how the compound formats of emblems, symbols, collage, and electronic media reveal the brain’s grappling to construct mental objects that are redoubled by prior associations. On the other hand, she compellingly shows that findings in evolutionary biology and the neurosciences are providing profound opportunities for understanding aesthetic conundrums as old and deep-seated as the human urge to imitate, the mapping of inner space, and the role of narrative and nonnarrative representation. As precise in her discussions of firing neurons as she is about the coordinating dynamics of image making, Stafford locates these major transdisciplinary issues at the intersection of art, science, philosophy, and technology. Ultimately, she makes an impassioned plea for a common purpose—for the acknowledgement that, at the most basic level, these separate projects belong to a single investigation. (shrink)

In his book SEXUAL DESIRE, Roger Scruton wrongly maintains that human sexual experience is essential intentional. His thesis depends on his highly revisionary definition of 'sexual desire', the artificial nature of which I expose and criticise. He admits that homosexual desire is capable of the same kind of intentionality as heterosexual desire, and is therefore not intrinsically obscene or perverted, but he advances reasons why homosexuality is morally different from heterosexuality and is therefore an object of disapproval. His arguments presuppose (...) 'an impassable moral divide' between the sexes, and are, on his own admission, not very cogent. Since he allows that homosexual desire is a natural and spontaneous phenomenon and also proposes that moral education should guide us towards a state in which our sexuality is entirely integrated within a life of personal affection and responsibility, consistency requires that he adopt a sexual ideology which does not discriminate against homosexuality. For homosexuals are unlikely to achieve the 'sexual integrity' which Scruton advocates (and which I endorse) if they are constantly encouraged to disparage their own sexual nature and if social institutions make no positive provision for them.

Modalists think that knowledge requires forming your belief in a “modally stable” way: using a method that wouldn't easily go wrong, or using a method that wouldn't have given you this belief had it been false. Recent Modalist projects from Justin Clarke-Doane and Dan Baras defend a principle they call “Modal Security,” roughly: if evidence undermines your belief, then it must give you a reason to doubt the safety or sensitivity of your belief. Another recent Modalist project from Carlotta Pavese (...) and Bob Beddor defends “Modal Virtue Epistemology”: knowledge is a belief that is maximally modally robust across “normal” worlds. We'll offer new objections to these recent Modalist projects. We will then argue for a rival view, Explanationism: knowing something is believing it because it's true. We will show how Explanationism offers a better account of undermining defeaters than Modalism, and a better account of knowledge. (shrink)

It is a commonplace amongst communitarians, socialists and feminists alike that liberalism is to be rejected for its excessive ‘individualism’ or ‘atomism,’ for ignoring the manifest ways in which we are ‘embedded’ or ‘situated’ in various social roles and communal relationships. The effect of these theoretical flaws is that liberalism, in a misguided attempt to protect and promote the dignity and autonomy of the individual, has undermined the associations and communities which alone can nurture human flourishing.My plan is to examine (...) the resources available to liberalism to meet these objections. My primary concern is with what liberals can say in response, not with what particular liberals actually have said in the past. Still, as a way of acknowledging intellectual debts, if nothing else, I hope to show how my arguments are related to the political morality of modem liberals from J.S. Mill through to Rawls and Dworkin. The term ‘liberal’ has been applied to many different theories in many different fields, but I’m using it in this fairly restricted sense. First, I’m dealing with a political morality, a set of moral arguments about the justification of political action and political institutions. Second, my concern is with this modem liberalism, not seventeenth-century liberalism, and I want to leave entirely open what the relationship is between the two. It might be that the developments initiated by the ‘new liberals’ are really an abandonment of what was definitive of classical liberalism. G.A. Cohen, for example, says that since they rejected the principle of ‘self-ownership’ which was definitive of classical liberalism, these new liberals should instead be called ‘social democrats.’My concern is to defend their political morality, whatever the proper label.

Every set can been thought of as a directed graph whose edge relation is ∈. We show that many natural examples of directed graphs of this kind are indivisible: for every infinite κ, for every indecomposable λ, and every countable model of set theory. All of the countable digraphs we consider are orientations of the countable random graph. In this way we find indivisible well‐founded orientations of the random graph that are distinct up to isomorphism, and ℵ1 that are distinct (...) up to siblinghood. (shrink)

Received opinion holds that it would be more efficient, hence more economical, to compress and thus dissolve the holdings of the Warburg Institute Library into an overarching university library system. This essay argues two points: first, that we should not be automatically persuaded by the popular and largely unexamined goal of efficiency; and second, that the Library indeed requires its own space but that that space must now be reconceived. In line with Aby Warburg's belief that the past should engage (...) the present by expanding and refreshing it, the Warburg Institute Library's rare and singular collections are less about the books and more about the uniqueness of the content and what it does. This essay proposes that what makes the Library vital to today's networked epistemology is the insights that its volumes provide to the varieties of human ordering, organization, formatting, and categorization—visibly exhibited in the spatial arrangement of its holdings. As its users have long felt, the Warburg is more than a library: it is a complex physical space demonstrating the formal evolution or framing of human thought. The Warburg should thus be reconceived as a “house museum” along these lines. (shrink)

Recent work on testimony has raised questions about the extent to which testimony is a distinctively second-personal phenomenon and the possible epistemic significance of its second-personal aspects. However, testimony, in the sense primarily investigated in recent epistemology, is far from the only way in which we acquire knowledge from others. My goal is to distinguish knowledge acquired from testimony (learning from being told) from knowledge acquired from teaching (learning from being taught), and to investigate the similarities and differences between the (...) two with respect to the interpersonal dimensions of their structures.

Many of us, and I am no exception, have been led to assume, almost un-consciously, that Śankara is India's greatest philosopher and that the non-dualist philosophy he consolidated, Advaita Vedānta, is the supreme spiritual philosophy of India, if not of the whole world. Dualist opponents like Madhva, on the other hand, have usually been appreciated very little, if at all. Several of my colleagues think of Madhva as a reactionary, if brilliant, theist whose philosophy best serves as a foil to (...) Śankara's. Madhva, it almost seems, is studied not for his own philosophical virtues but as a means the better to appreciate Śankara's. I believe that we must weigh more carefully the dualist position, particularly its trenchant critique of non-dualism. We may discover in the process that Śankara, whatever else he was – brilliant stylist, mystic par excellence , deft polemicist – was not the originator or consolidator of anything like an internally consistent metaphysics.

ABSTRACT:Many scholars and managers endorse the idea that the primary purpose of the firm is to make money for its owners. This shareholder wealth maximization objective is justified on the grounds that it maximizes social welfare. In this article, the first of a two-part set, we argue that, although this shareholder primacy model may have been appropriate in an earlier era, it no longer is, given our current state of economic and social affairs. To make our case, we employ a (...) utilitarian moral standard and examine the apparent logical sequence behind the link between shareholder wealth maximization and social welfare. Upon close empirical and conceptual scrutiny, we find that utilitarian criteria do not support the shareholder model; that is, shareholder wealth maximization is only weakly linked to social welfare maximization. In view of the dubious validity of this sequential argument, we outline some of the features of a superior corporate objective—a variant of normative stakeholder theory. In the second article, we will advance and defend our preferred alternative and then discuss some institutional arrangements under which it could be implemented. (shrink)

In their commentaries on Zoopolis, Alasdair Cochrane and Oscar Horta raise several challenges to our argument for a “political theory of animal rights”, and to the specific models of animal citizenship and animal sovereignty we offer. In this reply, we focus on three key issues: 1) the need for a groupdifferentiated theory of animal rights that takes seriously ideas of membership in bounded communities, as against more “cosmopolitan” or “cosmo- cosmopolitan” or “cosmo- cosmopolitan” or “cosmo- ” or “cosmo- or “cosmozoopolis” (...) alternatives that minimize the moral significance of boundaries and membership; 2) the challenge of defining the nature and scope of wild animal sovereignty; and 3) the problem of policing nature and humanitarian intervention to reduce suffering in the wild.

For many people "animal rights" suggests campaigns against factory farms, vivisection or other aspects of our woeful treatment of animals.

Barbara Stafford is a pioneering art historian whose research has long helped to bridge the divide between the humanities and cognitive sciences. In _A Field Guide to a New Meta-Field_, she marshals a distinguished group of thinkers to forge a ground-breaking dialogue between the emerging brain sciences, the liberal arts, and social sciences. Stafford’s book examines meaning and mental function from this dual experimental perspective. The wide-ranging essays included here—from Frank Echenhofer’s foray into shamanist hallucinogenic visions to David (...) Bashwiner’s analysis of emotion and danceability—develop a common language for implementing programmatic and institutional change. Demonstrating how formerly divided fields are converging around shared issues, _A Field Guide to a New Meta-Field _maps a high-level, crossdisciplinary adventure from one of our leading figures in visual studies.

This article critically evaluates current developments in marketing fair trade labelled products and "no sweat" manufactured goods, and argues that both the fair trade and ethical trade movements increasingly rely on strategies for bottom-up change, converting consumers "one cup at a time". This individualistic approach, which we call "shopping for a better world", must, we argue, be augmented by more collectivist approaches to affect transformative change. Specifically, we look at the concept of mission-driven organizations pursuing leadership roles in developing affinity (...) relationships to promote fair and ethical trade and developing ethical spaces. Increasingly, a range of organizations are restructuring their operations, so that their mission is reflected in ethical practices throughout their operations, including product sourcing and product sales. First, ethical purchasing policies operated by non-profits and public agencies represent markets through which fair/ethical products reach end consumers. The efforts discussed to create ethical spaces through direct democracy and electoral mandate build on a broad-based affinity with the principles of fair and ethical trade. Second, we explore the potential for "mission-driven" non-profit organiza- tions, such as zoos and aquaria for merging their mission of conservation education with their marketing activities through the operation of their shops and cafes. Interesting initiatives to link the conservation message to food choices is being undertaken by a number of zoos and aquaria, while there is scope for increased linkages in the giftware sold in their shops.

Philosophy has often been represented by its detractors, and even sometimes by its practitioners, as a subject which, unlike the natural sciences, exhibits a degree of progress far from commensurate with its long history. Many of the questions entertained by the ancients are still very much alive: answers proffered are put forward very tentatively, seldom meet with universal acceptance, and frequently give rise to controversy even more prolific than that which they were intended to lay low.

In the recent literature on the nature of knowledge, a rivalry has emerged between modalism and explanationism. According to modalism, knowledge requires that our beliefs track the truth across some appropriate set of possible worlds. Modalists tend to focus on two modal conditions: sensitivity and safety. According to explanationism, knowledge requires only that beliefs bear the right sort of explanatory relation to the truth. In slogan form: knowledge is believing something because it’s true. In this paper, we aim to vindicate (...) explanationism from some recent objections offered by Gualtiero Piccinini, Dario Mortini, and Kenneth Boyce and Andrew Moon. Together, these authors present five purported counterexamples to the sufficiency of the explanationist analysis for knowledge. In addition, Mortini devises a clever argument that explanationism entails the violation of a plausible closure principle on knowledge. We will argue that explanationism is innocent of all these charges against it, and we hope that the strength of the defense we offer of explanationism is evidence in its favor, and a reason to investigate explanationism further as the long-elusive truth about the nature of knowledge.

This small book is very large: it contains the living universe. It is a privilege to be asked to write this preface, and a delight to do so. That is because I recognize here a really important book, both in general and specifically. Before talking about the specific contents at all, I would like to explain why this is in general so.
