Observation in Science

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).

There is something important about the way human primates use touch in social encounters; for example, consider greetings in airports (hugs vs. handshakes) and the way children push each other in a playground (a quick push to warn, a really hard one when it is serious!). Human primates use touch as a way of conveying a wide range of social information. In this chapter I will argue that one of the best ways of understanding social cognition in non-human primates is (...) through touch. Moreover, I will argue that if we would like to describe the evolutionary history of social cognition, touch is one of the ideal modes to operationalize social interaction across different kinds of primates.

All methodologies used to characterize mother-infant interaction in non-human primates includes mother, infant, and other social factors. The chief difference is their understanding of how this interaction takes place. Using chimpanzees as a model, I will compare the different methodologies used to describe mother-infant interaction and show how implicit notions of communication and social interaction shape descriptions of this kind of interaction. I will examine the limitations and advantages of different approaches used in mother-infant studies and I will sketch an (...) alternative approach to studying mother-infant interaction in non-human primates that adopts Jerome Bruner’s developmental studies on human infant communication.

In his last book (2008), Bas van Fraassen, the originator of constructive empiricism, put forward a table containing a categorization of images. His aim, however, was to discuss the reality of what they represent and not addressing the issue of images per se. One of the consequences is that it remained an open question what ‘public hallucinations’ - reflections in the water, rainbows and the like - are. In this paper it will be defended that only images in the relevant (...) (representational) sense should be considered as such. For this and other reasons, van Fraassen’s diagram should be amended. Moreover, as Physics teaches us, the class of the so-called ‘images’ that are actually objects is wider than van Fraassen reckons. The set of the observable objects do not contain only concrete things, but goes beyond what ‘common sense realism’ suggests. In addition to rocks, oceans and bicycles, we can also see rainbows, reflections in the water and the like. (shrink)

In his famous book "Seeing Dark Things: The Philosophy of Shadows" (2008), Roy Sorensen put forward a ‘blocking theory of shadows’, a causal view on these entities according to which a shadow is an absence of light caused by blockage. This approach allows him to solve a quite famous riddle on shadows, ‘the Yale puzzle’, that was devised by Robert Fogelin in the late 1960s and that Sorensen presents in the form mentioned by Bas van Fraassen (1989). István Aranyosi has (...) recently criticized Sorensen’s solution to the Yale puzzle, on the grounds that it does not resist another version of the riddle, that Aranyosi calls ‘the Bilkent puzzle’. A new perspective on shadows, the ‘Material Exstitution View’, that allegedly permits to solve both puzzles, could be adopted as an alternative. In this paper I will show that Sorensen’s blockage theory can actually handle both the Yale and the Bilkent puzzle, plus another one that I put forward (‘the donut puzzle’), which instead is fatal to Aranyosi’s position. As Sorensen puts it, nothing aside from the original blockage of light is needed. (shrink)

According to Roy Sorensen, when one looks at the Moon, during a solar eclipse, what she sees is its inner part of the farther, reflective one, and not the always-facing-Earth side of our natural satellite. To make his point clearer, he put forward the famous example of a double eclipse involving the fictional planets Far and Near. From the observer’s vantage point, the two planets have the same apparent diameter and overlap. What the agent sees is a dark disk, but (...) believes that what she is seeing is Near, because Far is behind it. Sorensen claims that what she actually sees is planet Far and that the causal theory of perception explains why this is the case. Of course, this position stands against common sense. Sorensen shows that it counters Alvin Goldman’s renowned observation criteria too. Nonetheless, he maintains, since Near is causally idle and the agent does see something, the only possible conclusion is that she sees Far, pace Goldman – and common sense. In this paper, I try to demonstrate that Sorensen is wrong and that the correct solution to the eclipse riddle is that the observer sees Near. As a matter of fact, besides meeting common sense and Goldman’s observability criteria, Near can be legitimately be considered the object of a successful perceptual discrimination even in the light of the causal theory of perception.

Among philosophical analyses of Darwin’s Origin, a standard view says the theory presented there had no concrete observational consequences against which it might be checked. I challenge this idea with a new analysis of Darwin’s principal geographical distribution observations and how they connect to his common ancestry hypothesis.

Carl Hempel introduced what he called "Craig's theorem" into the philosophy of science in a famous discussion of the "problem of theoretical terms." Beginning with Hempel's use of 'Craig's theorem," I shall bring out some of the key differences between Hempel's treatment of the "problem of theoretical terms" and Carnap's in order to illuminate the peculiar function of Wissenschaftslogik in Carnap's mature philosophy. Carnap's treatment, in particular, is fundamentally antimetaphysical—he aims to use the tools of mathematical logic to dissolve rather (...) solve traditional philosophical problems—and it is precisely this point that is missed by his logically-minded contemporaries such as Hempel and Quine.

This paper examines the theoretical differences obtaining between a mechanist like Moore and a teleologist like Rychlak. It is shown that mechanistic formulations invariably reduce the account to material and efficient causation, whereas teleologists want to bring in formal-final cause descriptions as well. Mechanists frame their explanations in third-person terms whereas teleologists often seek a first-person formulation of behavior. Moore's references to "private events" are shown to be extraspectively understood. A major theme of this paper is that Skinner actually capitalized (...) on the intentional nature of human behavior, and that it would be fairly easy to reconceptualize his theory and its empirical support in teleological terms. Careful examination of both the contingency and the discriminative-stimulus constructs are made in support of this contention. (shrink)

I believe observation is valued by scientists because it is an objective source of information. Objective here can mean two things. First, observation could be objective in that it is an assured source of truths about the world, truths whose meaning is the same for everyone regardless of their personal theoretical vantage points. I criticize this construal of observational objectivity in chapter one. The guilty doctrine, which I entitle 'empiricistic epistemological foundationalism', is shown to be untenable on, in part, historical (...) grounds. The historical episode I deploy for this task is the early stages of quantum theory, an episode I return to at various times throughout the thesis in illustration of my philosophical points. The sense of objective I favour views empirical data as the locus of extensive interpersonal agreement. Observation, from this perspective, plays the role of a communal judge in arbitrating our theoretical disputes. Returning to early quantum theory , I show how observation could not have had the adjudicative effect it exhibited unless it were objective in this sense. ;A crucial philosophical problem I take up is to provide the best definition of observation suited to accomplish the normative goals set out above for empirical data. Two major contenders are presented in chapter two, the semantic and pragmatic theories of observation, and other pragmatically-based proposals are discussed at the end of chapter four. In the end, I show that the pragmatic theory of observation triumphs as the philosophically most responsible account of the value of scientific observations. ;The final chapter turns to an examination of the bearing of evidence on theory. From my particular pragmatic viewpoint, I describe first how the rationality of induction can be established, and following this I reassess the value of Hempel's classic list of confirmation principles. My final task is to use a new, overtly pragmatic definition of confirmation to re-evaluate the experimental confirmation by Rubens and Kurlbaum of Planck's quantum hypothesis. (shrink)

Ever since work of Paul Feyerabend, Russell Hanson and Thomas Kuhn in the 1960s, the thesis of the theory-ladenness of scientific observation has attracted much attention both in the philosophy and the sociology of science. The main concern has always been epistemic. It was argued –or feared– that if scientific observations depend on prevalent theories, an objective empirical test of theories and hypotheses by independent observation and experience is impossible. This suggests that theories might appear to be well confirmed by (...) observation, and yet it is not likely that they are largely true or empirically adequate. While some philosophers like Ian Hacking have argued that serious theory-dependence is less common than often assumed, sociologists such as David Bloor, Stephen Shapin, Karin Knorr-Cetina or Harry Collins have based their constructivist programs for the sociology of science on strong claims of theory-ladenness.

This is an important volume of seventeen essays that historicizes observation as a practice, concept and ideal. It belongs to the historiographical tradition of scrutinizing central aspects of the scientific enterprise such as experiments and objectivity that once appeared too self-evident to be probed. The challenge of historicizing such a significant idea is that it has to be a collective enterprise.The volume starts with three essays that provide a chronological survey of the period from 500 to 1800. Katherine Park, covering (...) the period from 500 to 1500, explains how observation for Cicero and Pliny had nothing to do with experiment or systematic investigation, but rather was a collective and largely anonymous process, associated with originary phrases of natural knowledge of a distant past and intelligible even by the illiterate. It was the basis for conjectural knowledge that lacked causal explanation. Observation of celestial events occurred from time to time, but in the context o .. (shrink)

A goal of most interpretations of quantum mechanics is to avoid the apparent intrusion of the observer into the measurement process. Such intrusion is usually seen to arise because observation somehow selects a single actuality from among the many possibilities represented by the wavefunction. The issue is typically treated in terms of the mathematical formulation of the quantum theory. We attempt to address a different manifestation of the quantum measurement problem in a theory-neutral manner. With a version of the two-slit (...) experiment, we demonstrate that an enigma arises directly from the results of experiments. Assuming that no observable physical phenomena exist beyond those predicted by the theory, we argue that no interpretation of the quantum theory can avoid a measurement problem involving the observer.

Agreement between "independent" measurements of a theoretically posited quantity is intuitively compelling evidence that a theory is, loosely speaking, on the right track. But exactly what conclusion is warranted by such agreement? I propose a new account of the phenomenon's epistemic significance within the framework of Bayesian epistemology. I contrast my proposal with the standard Bayesian treatment, which lumps the phenomenon under the heading of "evidential diversity".

We review the observational foundations of the ΛCDMΛCDM model, considered by most cosmologists as the standard model of cosmology. The Cosmological Principle, a key assumption of the model is shown to be verified with increasing accuracy. The fact that the Universe seems to have expanded from a hot and dense past is supported by many independent probes . The explosion of detailed observations in the last few decades has allowed for precise measurements of the cosmological parameters within Friedman–Lemaître–Robertson–Walker cosmologies leading (...) to the ΛCDMΛCDM model: an apparently flat Universe, dominated by a cosmological constant, whose matter component is dominantly dark. We describe and discuss the various observational probes that led to this conclusion and conclude that the ΛCDMΛCDM model, although leaving a number of open questions concerning the deep nature of the constituents of the Universe, provides the best theoretical framework to explain the observations.

New Methodological Perspectives on Observation and Experimentation in Science deals with a classic topic that is seen from new angles.

Attempts by twentieth-century historians to account for the successes and failures of the Hipparchian-Ptolemaic solar model provide valuable case studies for philosophers who are studying the relationship between observational data and theoretical constructs. A brief survey of recent literature on the solar model reveals that in some cases results which appear to be the product of highly accurate observation are, in fact, based on rather crude observations aided by a large measure of theoretical presupposition. On the other hand, mistaken results, (...) which have sometimes been explained as the outcome of theoretical bias or conscious deceit, can plausibly be accounted for as a result of honest mistakes at the observational level.

In the writings of scientists we find claim to the effect that we can observe items such as pulsars, gravity waves, quarks, electrons, etc. An epistemological theory, originally developed by Dretske and modified by Jackson, is used to give an account of such claims and the extent to which they may be deemed correct. The theory eschews talk of the theory-ladenness of observation while giving an account of how our observation reports may evolve with growth in scientific knowledge. The theory (...) is partially linked to Shapere's recent account of observation in science. (shrink)

Although quantum mechanics has significantly advanced our understanding of the physical world, it has also been a source of great confusion. Myriad interpretations, and interpretations of interpretations, have been proposed to try and explain away the seeming inconsistencies which lie at the heart of quantum mechanics. All of these attempts at interpretation center on the seemingly intractable measurement problem. In this essay I argue that a number of interpretations of quantum mechanics are plagued by inadequate and misleading assumptions about the (...) observer. These assumptions are based on a naïve “folk conception” of the observer. In discussing two phenomena studied in modern cognitive science, I will argue for a rejection of the naïve conception of the observer and adopt a more sophisticated view which offers a significant interpretational payoff. I argue that although the measurement problem in quantum mechanics appears to be a scientific problem requiring a scientific solution, it is plausible that the problem might be a pseudo-problem resulting from a conceptual confusion. The conceptual confusion is caused by naïve assumptions about the nature of the observer.1 Based on these arguments I will reevaluate a number of interpretations and assess the role of philosophy in interpreting quantum mechanics.

The concern with the objectivity of observations is as old as empirical study itself. Protagoras’ assertion that ‘Man is the measure of all things’, though not particularly directed at observations, raised general doubts concerning the objectivity of our beliefs. In the twentieth century, the concern has been brought under the banner ‘theory-ladenness of observation’. In simple terms, since observations are conducted and formulated in theory-specific contexts, they are inadvertently imbued with the prejudices of those contexts - the terms ‘theory’ and (...) ‘observation’ are here broadly construed. Accordingly, it is argued, observations cannot be neutral in the testing of theories. (shrink)

Discussions of theory-ladenness have traditionally focused on the extent to which observations and observational language are pure, i.e. unaffected by theory, and hence can function as neutral adjudicators in theory testing. By contrast, the purity of theories and of theoretical language is never brought into question. My aim in this paper is to contest this view by arguing that theories and theoretical terms can be afflicted by observation-ladenness.

Scientists obtain a great deal of the evidence they use by observingnatural and experimentally generated objects and effects. Much of thestandard philosophical literature on this subject comes from20th century logical positivists and empiricists, theirfollowers, and critics who embraced their issues and accepted some oftheir assumptions even as they objected to specific views. Theirdiscussions of observational evidence tend to focus on epistemologicalquestions about its role in theory testing. This entry follows theirlead even though observational evidence also plays important andphilosophically interesting roles (...) in other areas including scientificdiscovery and the application of scientific theories to practicalproblems.

This book develops an explanation for the roles of observation and theory in scientific endeavor that occupies the middle ground between empiricism and rationalism, and captures the strengths of both approaches. Brown argues that philosophical theories have the same epistemological status as scientific theories and constructs an epistemological theory that provides an account of the role that theory and instruments play in scientific observation. His theory of perception yields a new analysis of objectivity that combines the traditional view of observation (...) as the foundation of scientific objectivity with the contemporary recognition that observation is theory-dependent.

Operationalism and theoretical entities. The thesis of the“theory ladenness” of observation leads to an antinomy. In order to solve this antinomy a technical operationalism is sketched, according to which theories should in principle not contain anything that cannot be reduced to technical procedures. This implies the rejection of Quine's underdeterminacy thesis and of many views about the theoretical-observational distinction, e.g. neopositivistic views, van Fraassen's view, Sneed-Stegmüller's view. Then I argue for the following theses: 1. All scientific concepts are theory laden (...) in the sense that they allow us to anticipate possible experiences, but they have to be in principle fully observable, i.e. integrally convertible into operational-technical applications. 2. The observation/theory distinction can be maintained as a historical one: what is observable depends on the instruments that are available at any stage of the development of science. 3.In principle theoretical entities are empirically real in Hacking's sense. However, some aspects of Hacking's realism are to be criticized. Theoretical entities are to be resolved into the totality of the interrelated properties accessible to us by means of theoretical points of view embodied in scientific instruments. (shrink)

The nature of the connection between theory and observation has been a major source of difficulty for philosophers of science. It is most vexing for those who would reduce the terms of a theory to those of an observation language, e.g. Carnap, Braithwaite, and Nagel. Carnap's work, particularly his treatment of physical theories as partially interpreted formalisms, forms the point of focus of this paper. Carnap attempted to make the connection between theory and observation through correspondence postulates. It is pointed (...) out that such postulates depend in critical ways upon theoretical truths. This particular type of theoretical dependence produces serious trouble for Carnap's approach. For reasons given it may make it untenable. Furthermore, this problem when generalized creates difficulty for any similar reductionist program. Not only is this kind of theoretical dependence pointed out, but more important, the logical conditions which produce it are revealed. In this way light is shed upon the formal characteristics of the notion of theory dependence, especially upon the way in which observation terms depend upon theories for their meaning. (shrink)

If observation is 'theory-laden', how can there be 'observationally equivalent theories'? How can the observations 'laden' by one theory be 'the same as' those 'laden' by another? The answer might lie in the expressibility of observationally equivalent theories in a common mathematical formalism.
