The thesis is intended to contribute to the growing understanding of the indispensable role played by phenomenal consciousness in human cognition, and specifically in making our concepts of the external world available. The focus falls on so called observational concepts, a type of rudimentary, perceptually-based objective concepts in our repertoire — picking out manifest properties such as colors and shapes. A theory of such concepts gets provided, and, consequently, the exact role that perceptual consciousness plays (...) in making concepts of this sort available gets settled. In the first half of the thesis, observational concepts get construed as a special type of recognitional concepts. On an analogy with perceptual demonstratives, having such concepts would involve having non-trivial knowledge of their reference. The experiential basis of such concepts would, among other things, provide for such constitutive knowledge. The theoretical background relevant to the hypothesis gets provided in the first chapter. A defence of the hypothesis follows in the second. In the second half of the thesis, care is taken to distinguish among two ways in which the constitutive knowledge of the reference of an observational concept could be fleshed out. In the third chapter, perceptual experience is shown to provide the basis both for knowledge of observational properties by acquaintance, and for knowledge of the essence of such properties — provided that knowledge of essence gets construed in the right, modest way. It might be natural to take knowledge by acquaintance to be the sort relevant to observational concept possession, especially given that in the case of perceptual demonstratives this is the role likely played by experience. However, this initial impression proves to be mistaken. The constitutive knowledge of the referent of an observational concept turns out to consist in the capacity to determine a priori the essence of the respective property. To show this, an argument gets provided in the penultimate fourth chapter, based on the key role played by experiences of instances of observational properties in optimal viewing conditions in enabling the possession of the respective observational concept.

In “Study of Concepts”, Peacocke puts forward an argument for non-conceptualism derived from the possession conditions of observational concepts. In this paper, I raise two objections to this argument. First, I argue that if non-conceptual perceptual contents are scenario contents, then perceptual experiences cannot present perceivers with the circumstances specified by the application conditions of observational concepts and, therefore, they cannot play the semantic and epistemic roles Peacocke wants them to play in the possession conditions (...) of these concepts. Second, I argue that if non-conceptual perceptual contents are protopropositions, then Peacocke’s account of the possession conditions of observational concepts falls into the Myth of the Given.

In the first part of my paper I discuss eight arguments in favour of the theory-dependence of observation: realistic content, guidance function of theories, perception as cognitive construction, expectation-dependence of perception, theory-dependence of scientific data, continuity between observational and theoretical concepts, language-dependence, and meaning holism. I argue that although these arguments make correct points, they do not exclude the existence of observations that are weakly theory-neutral in the sense that they don’t depend on acquired background knowledge. In the (...) second part I suggest an experimental method, the method of ostensive learning experiments, by which the degree of theory- and language-independence of a concept can be tested. (shrink)

The chapter presents a brief case study, in which we can observe the impact of Pierre Hadot's ideas on Martin O’Hagan, a person not far removed from us in terms of space, time, and aspirations. Hadot's concept of “Philosophy as a Way of Life (PWL)” could provide an option for a person who, excluded from and/or disillusioned by Academic philosophy, still felt the need to search for answers to a few centrally important questions that had direct impact on his life. (...) Even the characteristic that has returned like a Leitmotif throughout this chapter — analytic philosophy's tendency to ignore the so‐called Big Questions, such as that of the meaning of life — can be illuminated by means of Kuhn's theories. The author hopes that the interest in Hadot's concept of PWL will contribute to the rehabilitation of philosophy as it was before its takeover by Academic philosophy. (shrink)

Through a study of a sophisticated contemporary scientific experiment, it is shown how and why use of the term 'observation' in reference to that experiment departs from ordinary and philosophical usages which associate observation epistemically with perception. The role of "background information" is examined, and general conclusions are arrived at regarding the use of descriptive language in and in talking about science. These conclusions bring out the reasoning by which science builds on what it has learned, and, further, how that (...) process of building consists not only in adding to our substantive knowledge, but also in increasing our ability to learn about nature, by extending our ability to observe it in new ways. The argument of this paper is thus a step toward understanding how it is that all our knowledge of nature rests on observation. (shrink)

In the article I discuss the conceptual problem of other minds and different approaches to mental concepts. Firstly, I introduce the conceptual problem and argue that solutions proposed by theory-theory and direct perception approach are inadequate. I claim that mental concepts are neither theoretical terms nor observational terms. Then, I consider third option which states that mental concepts are dispositional terms, i.e. they concern particular patterns (stereotypes) of behavior. Finally, I argue that dispositional approach is to (...) some extent coherent with phenomenological account and that phenomenological concept of embodiment can improve this position. (shrink)

This dissertation focuses on the philosophy of Sextus Empiricus, a skeptic who provides the most complete account of Pyrrhonian skepticism that survives from antiquity. In particular, this dissertation examines Sextus' account of skeptical assent, the attitude that structures and informs the life of the skeptic. Accordingly, this dissertation has two aims: first, to elaborate and defend a novel method of interpreting Sextus' claims and concepts, one based on their significance in ordinary life and language; and, second, to apply this (...) method to Sextus' claims about the nature of skeptical assent in order to generate a novel account thereof. In the first chapter, the most widely-held and influential interpretations of skeptical assent are elaborated and taxonomized. It is argued that all these interpretations neglect to pay sufficient attention to the self-reflexivity of Sextus' skepticism, in consequence of which Sextus' own claims about skeptical assent must be understood as expressing skeptical assent. It is argued, moreover, that this neglect of self-reflexivity cannot be remedied without abandoning these interpretations. In the second chapter, Sextus' claims about ordinary life are examined and it is argued that Sextus regards skepticism as a distinctive expression of ordinary life. However, ordinary life may be understood in two different ways and the failure to distinguish them has resulted in a misconception of Sextus' outlook. The two different conceptions are therefore elaborated and it is argued that Sextus' understanding of ordinary life accords with only one of them. Finally, responses are provided to some important objections to the close connection between iii skepticism and ordinary life. In the third and final chapter, Sextus' conception of ordinary life is deployed to produce a novel understanding of skeptical assent. The focus here is Sextus' account of assent in Outlines of Pyrrhonism 1.13. Each of the key concepts in that account are explained in light of chapter two's results. Additionally, the roots of a concept central to skeptical assent are located in Aristotle's methodological reflections. Finally, the novel account of skeptical assent is distinguished from two other closely related accounts.. iv. (shrink)

I flesh out the sense in which the informational approach to interpreting quantum mechanics, as defended by Pitowsky and Bub and lately by a number of other authors, is (neo-)Bohrian. I argue that on this approach, quantum mechanics represents what Bohr called a “natural generalisation of the ordinary causal description” in the sense that the idea (which philosophers of science like Stein have argued for on the grounds of practical and epistemic necessity) that understanding a theory as a theory of (...) physics requires that one be able to “schematise the observer” within it is elevated in quantum mechanics to the level of a postulate in the sense that interpreting the outcome of a measurement interaction, as providing us with information about the world, requires as a matter of principle, the specification of a schematic representation of an observer in the form of a ‘Boolean frame’—the Boolean algebra representing the yes-or-no questions associated with a given observable representative of a given experimental context. I argue that the approach’s central concern is with the methodological question of how to assign physical properties to what one takes to be a system in a given experimental context, rather than the metaphysical question of what a given state vector represents independently of any context, and I show how the quantum generalisation of the concept of an open system may be used to assuage Einstein’s complaint that the orthodox approach to quantum mechanics runs afoul of the supposedly fundamental methodological requirement to the effect that one must always be able, according to Einstein, to treat spatially separated systems as isolated from one another.

In our daily lives we conceive of our surroundings as an objectively given reality. The world is perceived through our senses, and ~hese provide us, so we believe, with a faithful image of the world. But occ~ipnally we are forced to realize that our senses deceive us, e. g., by illusions. For a while it was believed that the sensation of color is directly r~lated to the frequency of light waves, until E. Land (the inventor of the polaroid camera) showed (...) in detailed experiments that our perception of, say, a colored spot depends on the colors of its surrounding. On the other hand, we may experience hallucinations or dreams as real. Quite evidently, the relationship between the "world" and our "brain" is intricate. Another strange problem is the way in which we perceive time or the "Now". Psychophysical experiments tell us that the psychological "Now" is an extended period of time in the sense of physics. The situation was made still more puzzling when, in the nineteen-twenties, Heisenberg and others realized that, by observing processes in the microscopic world of electrons and other elementary particles, we strongly interfere with that world. The outcome of experiments - at least in general - can only be predicted statistically. What is the nature ofthis strange relationship between "object" and "observer"? This is another crucial problem of the inside-outside or endo-exo dichotomy. (shrink)

Summary The genealogy of observation as a philosophical term goes back to the ancient Greek astronomical and medical traditions, and the revival of the concept in the Renaissance also happened in the astronomical and medical context. This essay focuses primarily on the medical genealogy of the concept of observation. In ancient Greek culture, an elaboration of the concept of observation (tērēsis) first emerged in the Hellenistic age with the medical sect of the Empirics, to be further developed by the ancient (...) Sceptics. Basically unknown in the Middle Ages, the Empirics’ conceptualisation of tērēsis trickled back into Western medicine in the fourteenth century, but its meaning seems to have been fully recovered by European scholars only in the 1560s, concomitantly with the first Latin translation of the works of Sextus Empiricus. As a category originally associated with medical Scepticism, observatio was a new entry in early modern philosophy. Although the term gained wide currency in general scholarly usage in the seventeenth century, its assimilation into standard philosophical language was very slow. In fact, observatio does not even appear as an entry in the philosophical dictionaries until the eighteenth century—with one significant exception, the medical lexica, which featured the lemma, reporting its ancient Empiric definition, as early as 1564.

Alan Musgrave, Michael Friedman, Jeffrey Foss, and Richard Creath raised different objections against the Distinction between observables and unobservables when drawn within the confines of Bas C. van Fraassen's Constructive Empiricism, to the effect that the Distinction cannot be drawn there coherently. Van Fraassen has only responded to Musgrave but Musgrave claimed not to understand van Fraassen's succinct response. I argue that van Fraassen's response is not enough. What remains in the end is an unsolved problem which CE cannot afford (...) to leave unsolved, or so I argue; I then strengthen Musgrave's criticism and indicate that an extension of the epistemic policy of CE is mandatory to solve the problem. I also argue that Friedman's and Foss' objection against the Distinction in CE misses the mark on closer inspection. An objection due to Creath does hit the mark but can be taken care of without too much ado. All these objections seem alive and kicking until the present day; I try to put them all to rest. (shrink)

This paper argues that new light may be shed on mathematical reasoning in its non-pathological forms by careful observation of its pathologies. The first section explores the application to mathematics of recent work on fallacy theory, specifically the concept of an ‘argumentation scheme’: a characteristic pattern under which many similar inferential steps may be subsumed. Fallacies may then be understood as argumentation schemes used inappropriately. The next section demonstrates how some specific mathematical fallacies may be characterized in terms of argumentation (...) schemes. The third section considers the phenomenon of correct answers which result from incorrect methods. This turns out to pose some deep questions concerning the nature of mathematical knowledge. In particular, it is argued that a satisfactory epistemology for mathematical practice must address the role of luck. (shrink)

Using examples of observations of primates in the wild, I will focus in this chapter on the ways in which some of the main feminist critiques are applicable to the observation of non-human animals. In particular, I will focus on the relationship between primatology and various conceptions of human nature and on the fact that primatology has often been described as a “feminist science.” I argue that in primatology there is an openness to a diversity of approaches and to feminist (...) values that has made it possible for researchers to understand primates in new, more complex ways. Finally, I include a brief discussion of an avenue of future research that will show that even the feminist perspectives explored in this chapter are situated within a specific western background and that it is important to remember that this feminist perspective is just one among many different perspectives. To illustrate variations in the roles that feminist critiques can play in animal observation, I will use examples from my own personal experience of Latinx identity while conducting research in Gombe National Park (Tanzania, Africa).

This paper presents a specific concept of the legal system, bringing a contribution to the Theory of Law, from the line of analysis of the Semiotics of Law. The entire methodological approach of this concept is based on the contributions of the École de Paris, from a theoretical-semiotic perspective derived from the studies of Algirdas Julien Greimas. The analysis seeks to further and qualify previous studies and publications, and focuses on the task of presenting the concept of juridicity, deriving the (...) description of the concept of the legal system from it, understood as a set of connections between legal texts. Consequently, the paper presents a Mesh Model for the description of the legal system, replacing the positivist concept of the Pyramid Model, through restoring the relationship between Law and Moral, between Law and Society and Law and Justice. Throughout the theoretical explanation, the paper tries to trace, develop and qualify the main points with arguments that distinguish the operation of the legal system, such as the concentric movement, micro-universes of meaning, discursive practices, the task of legal actors, dynamic inter-textuality, the role of interpretation, the process of the production of legal meaning and the search for textual justice.

Context: Society is faced with “wicked” problems of environmental sustainability, which are inherently multiperspectival, and there is a need for explicitly constructivist and perspectivist theories to address them. Problem: However, different constructivist theories construe the environment in different ways. The aim of this paper is to clarify the conceptions of environment in constructivist approaches, and thereby to assist the sciences of complex systems and complex environmental problems. Method: We describe the terms used for “the environment” in von Uexküll, Maturana & (...) Varela, and Luhmann, and analyse how their conceptions of environment are connected to differences of perspective and observation. Results: We show the need to distinguish between inside and outside perspectives on the environment, and identify two very different and complementary logics of observation, the logic of distinction and the logic of representation, in the three constructivist theories. Implications: Luhmann’s theory of social systems can be a helpful perspective on the wicked environmental problems of society if we consider carefully the theory’s own blind spots: that it confines itself to systems of communication, and that it is based fully on the conception of observation as indication by means of distinction.

The concept of observability of entities in physical science is typically analyzed in terms of the nature and significance of a dichotomy between observables and unobservables. In the present work, however, this categorization is resisted and observability is analyzed in a descriptive way in terms of the information which one can receive through interaction with objects in the world. The account of interaction and the transfer of information is done using applicable scientific theories. In this way, the question of observability (...) of scientific entities is put to science itself. ;Several examples are presented which show how this interaction-information account of observability is done. It is demonstrated that observability has many dimensions which are, in general, orthogonal. The epistemic significance of these dimensions is explained. ;This study is intended primarily as a method for understanding problems of observability rather than as a solution to those problems. The important issue of scientific realism and its relation to observability, however, demand attention. Hence, the implication of the interaction-information account for realism, and the implication of realism for the interaction-information account of observability are discussed in the end. (shrink)

Byron’s sharp insights propose an alternative ethical model based on engaged social participants who are committed to advancing the common good in (...) these difficult times. (shrink)

Founding our analysis on the Geneva-Brussels approach to the foundations of physics, we provide a clarification and classification of the key concept of observation. An entity can be observed with or without a scope. In the second case, the observation is a purely non-invasive discovery process; in the first case, it is a purely invasive process, which can involve either creation or destruction aspects. An entity can also be observed with or without a full control over the observational process. (...) In the latter case, the observation can be described by a symmetry breaking mechanism, through which a specific deterministic observational process is selected among a number of potential ones, as explained in Aerts’ hidden measurement approach. This is what is called a product test, or product observation, whose consequences are that outcomes can only be predicted in probabilistic terms, as it is the case in typical quantum measurements. We also show that observations can be about intrinsic (stable) properties of the observed entity, or about relational (ephemeral) properties between the observer and observed entities; also, they can be about intermediate properties, neither purely classical, nor purely quantum. Our analysis allows us to propose a general conceptual characterization of quantum measurements, as observational processes involving three aspects: (1) product observations, (2) pure creation aspects and (3) ephemeral relational properties. We also discuss the important concept of non-spatiality and emphasize some of the differences and similarities between quantum and classical/relativistic observations. (shrink)

ABSTRACT In an unpublished anatomical treatise written around 1670, the English anatomist and fellow of the Royal Society of London Edmund King proposed that the human body was ultimately an assemblage of tubes and contained liquids. Without literally seeing every of its constituents to be tubular, how did King come to posit a tubular body? This article tackles the question by examining King’s inquiry about the pulse against his framing of the circulatory system into a universally tubular model. Asking how (...) King registered this model despite the limited visibility of vascularity in practice, I discuss the place of analogy in his anatomical observation. I argue that analogy constituted an essential strategy for extending what King had perceived to account for the hardly perceptible nuances of the human body. I concentrate on two of his analogies, in which the artery was compared to the cord and the ureter. These two analogies revealed remarkable epistemic potency in representing and reasoning the pulse as the inherent motion of the living artery. They suggest that in seventeenth-century observation accounts, analogy was not simply a rhetoric suspicious of violating the principle of scientific empiricism; rather, they opened up ways of seeing and imagining nature.

This paper contains five observations concerning the intended meaning of the intuitionistic logical constants: (1) if the explanations of this meaning are to be based on a non-decidable concept, that concept should not be that of `proof"; (2) Kreisel"s explanations using extra clauses can be significantly simplified; (3) the impredicativity of the definition of → can be easily and safely ameliorated; (4) the definition of → in terms of `proofs from premises" results in a loss of the inductive character of (...) the definitions of ∨ and ∃ and (5) the same occurs with the definition of ∀ in terms of `proofs with free variables".

The phrase ‘synthetic biology’ is used to describe a set of different scientific and technological disciplines, which share the objective to design and produce new life forms. This essay addresses the following questions: What conception of life stands behind this ambitious objective? In what relation does this conception of life stand to that of traditional biology and biotechnology? And, could such a conception of life raise ethical concerns? Three different observations that provide useful indications for the conception of life in (...) synthetic biology will be discussed in detail: 1. Synthetic biologists focus on different features of living organisms in order to design new life forms, 2. Synthetic biologists want to contribute to the understanding of life, and 3. Synthetic biologists want to modify life through a rational design, which implies the notions of utilising, minimising/optimising, varying and overcoming life. These observations indicate a tight connection between science and technology, a focus on selected aspects of life, a production-oriented approach to life, and a design-oriented understanding of life. It will be argued that through this conception of life synthetic biologists present life in a different light. This conception of life will be illustrated by the metaphor of a toolbox. According to the notion of life as a toolbox, the different features of living organisms are perceived as various rationally designed instruments that can be used for the production of the living organism itself or secondary products made by the organism. According to certain ethical positions this conception of life might raise ethical concerns related to the status of the organism, the motives of the scientists and the role of technology in our society.

I argue for an alternative to Quine’s conception of observation sentences, one that better satisfies the roles Quine envisages for them, and that otherwise respects Quinean constraints. After reviewing a certain predicament Quine got into in balancing the needs of the intersubjectivity of observation sentences with his notion of the stimulus meaning of an observation sentence, I push for replacing the latter with what I call the ‘stimulus field’ of an observation sentence, a notion that remains ‘proximate’ but is shared (...) between different language users. Throughout, I emphasize the epistemological role of observation sentences. (shrink)

An interesting metatheoretical controversy took place during the 1980’s and 1990’s between pattern and phylogenetic cladists. What was always at stake in the discussion was not how work in systematics should be carried out, but rather how this practice should be metatheoretically interpreted. In this article, we criticize Pearson’s account of the metatheoretical factors at play in this discussion. Following him, we focus on the issue of circularity, and on the role that phylogenetic hypotheses play in the determination of “primary (...) homologies”. Pearson argues that the recognition of primary homologies cannot be achieved without recourse to previous phylogenetic knowledge, and that to claim otherwise is to state that primary homologies are observable. To show why that view would be inadequate, he appeals to Hanson’s views about theory-laden observation, alongside with a specific case study, which allegedly illustrates the more complex relation between observation and theory. We will argue that the pattern cladists’ point is better addressed by taking a quite different approach: instead of thinking in terms of observability, the topic can be tackled by paying attention to the way in which concepts are determined. We will take the notion of T-theoricity from metatheoretical structuralism and show that, once the issue is discussed with the appropriate metatheoretical framework, the alleged counterexample brought up by Pearson is not problematic at all for pattern cladism.

Observer memories, memories where one sees oneself in the remembered scene, from-the-outside, are commonly considered less accurate and genuine than visual field memories, memories in which the scene remembered is seen as one originally experienced it. In Remembering from the Outside (OUP, 2019), Christopher McCarroll debunks this commonsense conception by offering a detailed analysis of the nature of observer memories. On the one hand, he explains how observer and field perspectives are not really mutually exclusive in an experience, including memory (...) experiences. On the other hand, he argues that in observer memories there is no additional explicit representation of oneself experiencing the event: the self-presence is transparent and given by the mode of presentation. Whereas these are two lines of strategic and original argumentation, they are not exempt of problems. In this critical notice, I focus on the problematic aspects of McCarroll’s account. I show that it presents some issues that affect the internal coherence of the overall framework, and that some aspects and central notions would have needed more development to offer a precise picture of the nature of observer memories.

Hannah Arendt claims the concept of brotherhood presents false notions of political community that elide historic hatreds of others and threaten modern political life. This paper explores Arendt’s critical assessment of the concept of brotherhood in order to reflect on one specific example: the politics of the Muslim Brotherhood in Egypt in the wake of the Arab Spring of 2011. While some observers reject Arendt’s assessment of brotherhood as too narrow, her criticisms raise useful questions about democracy and plurality, which (...) confront any community that exhorts its members to act as ‘brethren’ rather than as ‘citizens.’ The Muslim concept of brotherhood suggests many different possibilities for belonging: a classic universalism of the Abrahamic natural law tradition; a progressive counter-public sphere; and as well the authoritarian private community of believers as represented in the early writings of the Muslim Brotherhood leadership. Therefore, the politically controversial Muslim Brotherhood has no monopoly over the understanding of the Muslim concept of brotherhood. However, it is the most powerful, most well-organized brotherhood movement. The paper opens and ends with reflections on the Arab Spring of 2011, its one-year anniversary in January 2012, and considers other possibilities for the concept of brotherhood against the backdrop of Arendt’s analysis.

A long series of studies in social psychology have shown that the explanations people give for their own behaviors are fundamentally different from the explanations they give for the behaviors of others. Still, a great deal of uncertainty remains about precisely what sorts of differences one finds here. We offer a new approach to addressing the problem. Specifically, we distinguish between two levels of representation ─ the level of linguistic structure (which consists of the actual series of words used in (...) the explanation) and the level of conceptual structure (which consists of the concepts these words are used to express). We then formulate and test hypotheses both about self-other differences in conceptual structure and about self-other differences in the mapping from conceptual structure to linguistic structure.

We develop a relativistic perspective on structures of quantum observables, in terms of localization systems of Boolean coordinatizing charts. This perspective implies that the quantum world is comprehended via Boolean reference frames for measurement of observables, pasted together along their overlaps. The scheme is formalized categorically, as an instance of the adjunction concept. The latter is used as a framework for the specification of a categorical equivalence signifying an invariance in the translational code of communication between Boolean localizing contexts and (...) quantum systems. Aspects of the scheme semantics are discussed in relation to logic. The interpretation of coordinatizing localization systems, as structure sheaves, provides the basis for the development of an algebraic differential geometric machinery suited to the quantum regime.

Observation and conceptual interpretation constitute the two major ways through which human beings engage the world. _The World Observed/The World Conceived _presents an innovative analysis of the nature and role of observation and conceptualization. While these two actions are often treated as separate, Hans Radder shows that they are inherently interconnected-that materially realized observational processes are always conceptually interpreted and that the meaning of concepts depends on the way they structure observational processes and abstract from them. He (...) examines the role of human action and conceptualization in realizing observational processes and develops a detailed theory of the relationship between observation, abstraction, and the meaning of concepts. This book provides a critical analysis of the work of various other philosophers and their accounts of scientific and ordinary-life observation and conceptualization. Radder discusses the formation and nature of concepts and demonstrates how concepts structure the phenomenal world. He then introduces and defines the notions of extensible concepts, abstraction and nonlocal meanings and explores the philosophical implications of his theory. _The World Observed/The World Conceived_ offers fresh insights in practices of observation and conceptualization, that will prove useful to many areas of scholarly study including ontology, epistemology, philosophy of language, philosophy of science, science studies, and cognitive science.

This collection of five essays by Germany’s most prominent and influential social thinker both links Luhmann’s social theory to the question “What is modern about modernity?” and shows the origins and context of his theory. In the introductory essay, “Modernity in Contemporary Society,” Luhmann develops the thesis that the modern epistemological situation can be seen as the consequence of a radical change in social macrostructures that he calls “social differentiation,” thereby designating the juxtaposition of and interaction between a growing number (...) of social subsystems without any hierarchical structure. “European Rationality” defines rationality as the capacity to see the difference between systems and their environment as a unity. Luhmann argues that, in a world characterized by contingency, rationality tends to become coextensive with imagination, a view that challenges their classical binary opposition and opens up the possibility of seeing modern rationality as a paradox. In the third essay, “Contingency as Modern Society’s Defining Attribute,” Luhmann develops a further and probably even more important paradox: that the generalization of contingency or cognitive uncertainty is precisely what provides stability within modern societies. In the process, he argues that medieval and early modern theology can be seen as a “preadaptive advance” through which Western thinking prepared itself for the modern epistemological situation. In “Describing the Future,” Luhmann claims that neither the traditional hope of learning from history nor the complementary hope of cognitively anticipating the future can be maintained, and that the classical concept of the future should be replaced by the notion of risk, defined as juxtaposing the expectation of realizing certain projects and the awareness that such projects might fail. The book concludes with “The Ecology of Ignorance,” in which Luhmann outlines prospective research areas “for sponsors who have yet to be identified.”. (shrink)
