Sellars (1963) distinguished in Empiricism and Philosophy of Mind between ordinary discourse, which expressed his “manifest image”, and scientific discourse, which articulated his “scientific image” of man-in-the-world in a way that is both central and problematic to the rest of his philosophy. Our contention is that the problematic feature of the distinction results from Sellars theory of inner episodes as theoretical entities. On the other hand, as Sellars attempted to account for our noninferential knowledge of such states, (...) particularly in correspondence with Castañeda, discussed by Lehrer and Stern (2000), he is lead to account of representation of such states that incorporates the states into what Lehrer has called exemplar representation (2004, 2011a) and Ismael reflexive self-description (2007). What is common to the three accounts, with some differences, is that such states may be function reflexively in selfrepresentation. Our argument is that the elaboration of this account, suggested in Sellars, shows how the discourse of the manifest image can be transformed into the discourse of the scientific image as self-representations of scientific entities.

In a famous essay, Wilfrid Sellars makes a distinction between the manifest and scientific images.1 According to Sellars, these images represent the two dominant conceptual frameworks by which we understand ourselves as persons-in-the-world. The manifest image utilizes "perennial philosophy" and "sophisticated common sense" to effect that understanding, while the scientific image employs the resources of theoretical physics. The challenge for the philosopher, Sellars argues, is to fuse these two complete and competing images into (...) a single, synoptic view. It is important to note, however, that the fusion Sellars envisions is not between two equally adequate frameworks. Rather, he claims, the scientific image is more adequate than its manifest counterpart. Briefly put, he maintains that the former provides a coherent account of the mind and the world, while the latter is essentially dualistic. For this reason, the scientific image merits primacy in his synoptic view. ;The task of this dissertation is to assess the ultimate adequacy of Sellars's claim. I proceed by placing Sellars in conversation with Hilary Putnam, Richard Rorty and John McDowell, who, while owing significant philosophical debts to Sellars, do not believe we must privilege the scientific image to achieve a coherent account of the mind and the world. In effect, they argue that the manifest image is an entirely legitimate framework for addressing a problem that has haunted philosophy since the seventeenth century. By doing so, Putnam, Rorty and McDowell help us to see that there is something wrong with the way in which Sellars depicts the relationship between the manifest and scientific images---i.e. as complete and competing visions of persons-in-the-world. In the end, the efforts of Putnam, Rorty and McDowell remind us that resolving the difficulties that are implicit to the mind-world relation demands the resources of both images or frameworks; that is to say, it demands that we see the manifest and scientific images as partial and complementary, rather than complete and competing visions of persons-in-the-world. ;1See Wilfrid Sellars, "Philosophy and the Scientific Image of Man," reprinted in Science, Perception and Reality , 1--40.

Robert B. Brandom’s From Empiricism to Expressivism ranges widely over fundamental issues in metaphysics, with occasional forays into epistemology as well. The centerpiece is what Brandom calls ‘the Kant-Sellars thesis about modality’. This is ‘[t]he claim that in being able to use ordinary empirical descriptive vocabulary, one already knows how to do everything that one needs to know how to do, in principle, to use alethic modal vocabulary – in particular subjunctive conditionals’. Despite claiming descent from Sellars, Brandom defends here (...) a version of modal realism and tries hard to limit Sellarsian nominalism, all in the service of elaborating Brandom’s own version of pragmatism. The range of issues Brandom addresses defies adequate consideration in a critical notice, so I confine myself here to a single issue: What is.. (shrink)

There are striking differences between the scientific theoretical description of the world and the way it seems to us. The consequent task of relating science to ’the world we live in’ has been a problem throughout the history of science. But have we made this an impossibility by how we formulate the problem? Some say that besides the successive world-pictures of science there is the world-picture that preceded all these and continues to exist by their side, elucidated by more (...) humanistic philosophers. Wilfrid Sellars codified this conviction in his dichotomy of scientific image and manifest image. Others say that all our world-pictures are transient, evolve, conflict with and replace each other, undergo violent revolutions as well as periods of normal development, and may be incommensurable, allowing of no meaningful dialogue. All such formulations may themselves be tendentious metaphysics, full of false contrasts. Insistence on a radical separation between science and what we have apart from science, on the impossibility of accommodating science without surrender, may be a way of either idolizing or demonizing science rather than understanding it.

ABSTRACTThis paper distinguishes between the theoretical scientific image and the practical scientific image. The popular idea that there is a conceptual clash between the scientific and manifest images of the world is revealed as largely illusory. From the perspective of a liberal naturalism, the placement problem for ‘problematic’ entities or truths is not solved but dissolved. Persons, say, are not posits of any explanatory science, but beings acknowledged as rational agencies in second-personal space. Core elements (...) of the manifest image are more deeply rooted in our conceptual scheme than any version of the scientific image. (shrink)

In his new book, Brandom offers a new argument against the viability of Sellars’ scientific naturalism. Brandom attempts to show that if the Sellarsian it scientia mensura principle is understood as implying that manifest-image objects exist only if they are identical to scientific-image objects, it is undermined by the ‘Kant–Sellars’ thesis about identity which implies that manifest-image objects cannot be identical to scientific-image objects. This conclusion can be evaded by construing the relation between manifest (...) and scientific objects as weaker than that of identity, namely as a relation between manifest-image functional roles and scientific-image realizers. But Brandom again argues that even this weaker construal of the scientia mensura thesis is in conflict with another Sellarsian argument, this time against phenomenalism. It will be argued that this is not so. I will, moreover, suggest that the ‘function-realizer’ construal of the manifest-scientific image distinction is indeed tenable—especially if the process of determining the scientific-image realizers of functional roles specified in manifest-image is understood as the culmination of a self-correcting dynamic and diachronic process of conceptual change. Finally, I will argue that while Brandom is right to point out that Sellars’ adherence to the scientia mensura principle is based on a ‘unity-of-science’ view, he is wrong to think that his argument for the contrary conclusion is successful, because Brandom’s argument does not automatically tell against a weaker ‘unity-of-science’ view according to which incommensurability of explanatory levels in science is a pragmatically indispensable yet in principle dispensable feature of empirical inquiry.

The Sellarsian task of ontology is to reconcile two seemingly divergent images of ordinary objects such as persons, tomatoes and tables, namely, the manifest image of common sense and the scientific image provided by fundamental physics (Sellars, Science, Perception, and Reality, 1963). Can the genuine categories of the ontologies of Substantialism (Heil, The World as We Find It, 2012), Structural Realism (Ladyman and Ross,Every Thing Must Go: Metaphysics Naturalized, 2007; French, The Structure of the World: Metaphysics and (...) Representation, 2014), and Factualism (Cumpa, ‘A Materialist Criterion of Fundamentality’, American Philosophical Quarterly, 2014), such as ‘substance’, ‘structure’, and ‘fact’, help us to solve the problem of the reconciliation of the two images of ordinary objects? In this paper I defend the thesis that the ontology of Factualism does a better job of reconciling the manifest and the scientific images of ordinary objects than other ontologies. (shrink)

Wilfrid Sellars famously argued that we find ourselves simultaneously presented with the scientific and manifest images and that the primary aim of philosophy is to reconcile the competing conceptions of ourselves and our place in the world they offer. I first argue that Sellars’ own attempts at such a reconciliation must be judged a failure. I then go on to point out that Sellars has invited us to join him in idealizing and constructing the manifest and (...) scientific images by conflating a number of importantly distinct contrasts between heterogeneous forms of representation we employ and to argue that we are better off declining this invitation. Recognizing the important differences between these contrasts does not simply obviate the problems of integrating, connecting, and reconciling the various sorts of representations we have of various parts of the world and our own place within it, but it reveals as misguided the notion that there is just a single, fundamental problem of such reconciliation to be solved. It also suggests a potentially far more promising starting point for trying to satisfy the fundamental ambition Sellars attributes to philosophical inquiry itself. (shrink)

The paper bridges between a science-based metamathematical model of emerging truth and truth emerging from inquiry within ordinary contexts of argumentation. This requires that the underlying intuitions driving the notion of truth in the scientific image be made clear and analogues identified in a manner that permits their application within the ordinary contexts found in the manifest image.

Claims such as ‘there are no tables and chairs’ have become increasingly common in the philosophical context, and eliminativism is now a fairly well-established position in contemporary debates in analytic metaphysics. This outbreak of eliminativism has prompted a number of responses aimed at saving the manifest image of reality. Prominent amongst the attempts to save the manifest image is a view, powerfully articulated by Frank Jackson in From Metaphysics to Ethics , according to which the manifest properties (...) of objects, properties such as solidity or fragility, can be spared from the eliminativist’s guillotine if it can be shown that they are entailed (through the relation of supervenience) by scientific properties. Jackson’s strategy for saving the manifest image rests on a modest conception of the role of conceptual analysis in metaphysics. On this view, the role of conceptual analysis is modest because it is not the task of philosophy to establish a priori what there is, but rather to determine which features of the manifest image can be located within the scientific image: the manifest properties which cannot be so located are shown to be rogue concepts that have no place in serious metaphysics. This chapter argues against the attempt to save the manifest image by invoking the relation of entailment (whether that implied by the notion of supervenience or by the more traditional notion of analytic entailment) on the grounds that the manifest image is sui generis. The defence of the manifest image that I propose as an alternative here rests on the idealist assumption that knowledge makes a difference to what is known, and that since the manifest and the scientific image are the correlative of two different ways of knowing they do not compete with one another. I call the idealist view that knowledge makes a difference to what is known the Reciprocity Thesis. Rather than seeking to determine what kind of manifest image one is entitled to have in order to comply with the scientific image, the Reciprocity Thesis limits the claims of science to its own explanandum and therefore sees no need to legitimise the manifest image by invoking the relation of entailment. The need to legitimise the manifest image in the light of the scientific image arises because the relation between the scientific and the manifest image has not been properly conceptualised. Once the scientific and the manifest image are understood as the correlative of different ways of knowing, the problem which the location strategy seeks to solve is shown to rest on a misconception of the relationship holding between different kinds of knowledge.

Fifty years ago the philosopher Wilfred Sellars identified two images of “man”, which he called respectively the “manifest image” and the “scientific image”; and he considered whether and how these two images could be reconciled. In this paper, I will very briefly look at the distinction drawn by Sellars and at his suggestions for reconciliation of these images. I will suggest that a broad distinction as suggested by Sellars can indeed usefully be drawn, but that (...) the distinction can be more helpfully characterised than it was by Sellars. I will argue that there are more ways of reconciling the two images than those proposed by Sellars. And I will elaborate on what I think are the most promising lines along which the reconciliation could take place. (shrink)

Sellars claims completeness for both the “manifest” and the “scientific images” in a way that tempts one to assume that they are independent of each other, while, in fact, they must share at least one common element: the language of individual and community intentions. I argue that this significantly muddies the waters concerning his claim of ontological primacy for the scientific image, though not in favor of the ontological primacy of the manifest image. The lesson (...) I draw is that we need to reassess the aims of ontology. (shrink)

In this paper I argue that the clash of the Sellars’ two images is particularly acute in the case of time. In Time and the World Order Sellars seems embarked on a quest to locate manifest time in Minkowski spacetime. I suggest that he should have argued for the replacement of manifest time with the local, path-dependent time of the “scientific image”, just as he suggests that manifest objects must be replaced by their scientific (...) counterparts. (shrink)

The purpose of this paper is threefold: First, I provide a framework – based on Sellars' distinction between the manifest and the scientific image – for illuminating the distinction between liberal and ‘orthodox’ scientific naturalism. Second, I level a series of objections against expanded liberal naturalism and its core commitment to the autonomy of manifest-image explanations. Further, I present a view which combines liberal and scientific naturalism, albeit construed in resolutely non-representationalist terms. Finally, I attempt (...) to distinguish my own (Sellars- and Peirce-inspired) position from the very similar pragmatic liberal naturalist view, that of Huw Price. I do this by suggesting that a ‘monistic’ Peircian evolutionary naturalism which accepts the Sellarsian scientia mensura principle not only is consistent with ungrudging recognition of the irreducibility of normative facts and the plurality of our discursive practices, but also shows how this irreducibility, by being understood in terms of an evolution-by-selection of a population of perceptual-practical-inferential habits, can be at the same time considered as naturalistically explicable – without any appeal to an expanded manifest-image conception of nature. (shrink)

This paper addresses the question whether or not philosophical discourse can avail the categories of the scientific image. I argue that the clash of the images is bet- ter understood on the semantic rather than the ontologic level and that it results from the challenge to the representational adequacy of the categories tha articulate the conceptual repertoires of the manifest image. A challenge that will be met by a succesful recategoriza- tion of the concept of a person (...) in the scientific image. I suggest some reasons to believe that such a recategoritazion is possible in principle without dismantling the philosophical discourse. (shrink)

Most readers of Sellars' philosophy learn about a Manifest-Scientific Image distinction, and because apparently nothing significant hinges on what at first sight seems just a neologistic labeling of a familiar distinction, it is henceforth wrongly associated with a pre-systematic commonsense/scientific framework distinction. The Manifest Image is not identical to the commonsense framework; nor is the Scientific Image identical to the scientific framework. In this paper I will concern myself only with arguing that the (...) class='Hi'>Manifest Image is not identical to the commonsense framework. (shrink)

Most discussion of Sellars’ deployment of the distinct images of “man-in-the-world” in "Philosophy and the Scientific Image of Man" focus entirely on the manifest and the scientific images. But the original image is important as well. In this essay I explore the importance of the original image to the Sellarsian project of naturalizing epistemology, connecting Sellars’ insights regarding this image to recent work in cognitive development.

It is very contentious whether the features of the manifest image have a place in the world as it is described by natural science. For the advocates of strict naturalism, this is a serious problem, which has been labelled ‘placement problem’. In this light, some of them try to show that those features are reducible to scientifically acceptable ones. Others, instead, argue that the features of the manifest image are mere illusions and, consequently, have to be eliminated from (...) our ontology. In brief, the two options that are open to strict naturalists for solving the placement problem are ontological reductionism and eliminativism. Other advocates of naturalist philosophy, however, claim that both these strategies fail and, consequently, opt for ‘mysterianism’, the view according to which we cannot give up the recalcitrant features of the manifest image even if we are not able to understand the ways in which they could be reduced to the scientific features. Mysterianism has the merit of facing the difficulties that whoever wants to explain reductively, or explain away, the features of the manifest image encounters. It is also a defeatist philosophical view, though, since it considers the most important philosophical problems as unsolvable mysteries. For this reason, I argue that mysterianism can also be taken as a reductio of strict naturalism, given its presumption that all phenomena are either explainable by the natural sciences or to be rejected as illusory. In this article, it is argued that the failures of reductionism, eliminativism and mysterianism should teach us that both the scientific image and the manifest image of the world are essential and mutually irreducible but not incompatible with each other. To support this claim, in the second part of the article, the case of free will is discussed. (shrink)

Exploration of INTERSUBJECTIVITY is continued. Different kinds of if are differentiated and signs for its presence and effects are shown. The difference between it, subjectivity and objectivity are explored. Intersubjectivity is crucial and universal for general everyday discourse in all cultures, sub-cultures, institutions, communities and socio-cultural practices such as religion, sport, etc or the so-called Manifest Image. It is essential for specialized areas, for example religion, sport and disciplines such as the humanities, arts, sciences, philosophy and all institutions. It (...) is a necessity for both cultural, social, interpersonal as well as intra-personal existence, emotions, attitudes, values and norms. But, it is not limited to human existence, life-worlds, realities and worlds, but also required for animals and all organisms. Object Oriented Ontology would emphasize that is it not merely something anthropocentric and restricted to human existence and consciousness (and anthropocentric interpretations of and projections on other objects, non-human creatures and all organisms, as well as all objects.. In the case of the latter one would probably replace the notion of intersubjectivity with terms such as energy and other ways of action and interaction for example intra- and inter-atoms.) In the Appendix is included work related to the above by others such as Sellars, Brandom (and his two images, Manifest and Scientific), Davidson, Dennett, Habermas, Nagel, etc. (shrink)

It is often stated that the image of the world which our senses present to us contradicts the scientific worldview in important respects. I challenge this position through a number of arguments centered on the nature of perception and of perceived qualities.

Sellars claims completeness for both the “manifest” and the “scientific images” in a way that tempts one to assume that they are independent of each other, while, in fact, they must share at least one common element: the language of individual and community intentions. I argue that this significantly muddies the waters concerning his claim of ontological primacy for the scientific image, though not in favor of the ontological primacy of the manifest image. The lesson (...) I draw is that we need to re-assess the aims of ontology. (shrink)

Davidson’s anomalous monism is based on the assumption that a human being can be described or accounted for in two very different ways, using two very different and indeed incommensurable conceptual frameworks, namely the physicalistic vocabulary of science and the mentalistic vocabulary employed by the ‘theories’ we make about each other when we interact and communicate. Also Sellars maintains that we have two alternative pictures of the world and especially of us humans as its parts, namely the scientific image (...) and the manifest image. At first sight, the views of the two philosophers may seem quite similar; however, the true extent of this apparent similarity is worth exploring. To that end, in this paper we tackle the following questions: Are Sellars’ reasons for claiming the irreducibility of his manifest image to the scientific image the same or similar to those that Davidson has for asserting the irreducibility of his mentalistic idiom to the scientific one? Is the normativity informing Sellars’ manifest image of the same kind as that informing Davidson’s mentalistic idiom? Do the notions of rationality considered by Sellars and Davidson coincide?

The philosophical tradition of phenomenology, with its focus on human bodily perception, can be used to explore the ways scientific instrumentation shapes a user’s experience. Building on Don Ihde’s account of technological embodiment, I develop a framework of concepts for articulating the experience of image interpretation in science. These concepts can be of practical value to the analysis of scientific debates over image interpretation for the ways they draw out the relationships between the image-making processes and the rival (...) scientific explanations of image content. As a guiding example, I explore a contemporary debate over images of the surface of Mars which reveal a landmass that resembles river delta formations on Earth, and which thus has important implications for the history of Martian climate and water flow. The phenomenological framework I develop can be used to help evaluate the different interpretations on offer for these images, and to analyze the roles in this discussion played by spacecraft equipped with cameras and laser and thermal imaging devices.

The distinction between the manifest and the scientific image of man- in-the-world is widely seen as crucial to Wilfrid Sellars's philosophical work. The present essay agrees with this view. It contends, however, that precisely because the distinction is important, we should not hurry to a quick and superficial understanding of it. The essay identifies several oversimplifications that can be found in the literature on the topic and argues that they are at least partly rooted in too rigid a (...) view of the role that the two-image distinction plays in Sellars's philosophy. It shows that this rigid approach is quite common in the secondary literature, either explicitly or by implication. It then presents a more cautious, flexible approach to the problem of the two images and explains why this approach is fruitful on the basis of textual evidence, along with the overall advantages of interpreting Sellars's thought as a whole.

This book offers new insights into the nature of human rational capacities by engaging inferentialism with empirical research in the cognitive sciences. Inferentialism advocates that humans' unique kind of intelligence is discursive and rooted in competencies to make, assess and justify claims. This approach provides a rich source of valuable insights into the nature of our rational capacities, but it is underdeveloped in important respects. For example, little attempt has been made to assess inferentialism considering relevant scientific research on (...) human communication, cognition or reasoning. By engaging philosophical and scientific approaches in a productive dialogue, this book shows how we can better understand human rational capacities by comparing their respective strengths and weaknesses. In this vein, the author critically revisits and constructively develops central themes from the work of Robert Brandom and other language rationalists: the nature of the assertoric practice and its connection to reasoned discourse, the linguistic constitution of the shared space of reasons, the social nature and function of reasoning, the intersubjective roots of social-normative practices and the nature of objective thought. Practices of Reason will be of interest to scholars and advanced students working in philosophy of mind, philosophy of language and philosophy of logic. (shrink)

I defend a pragmatist reinterpretation of Sellars’s famous manifest-scientific distinction. I claim that in order to do justice to this important distinction we must first recognize, despite what philosophers—including, arguably, Sellars—often make of it, that the distinction does not draw an epistemological or metaphysical boundary between different kinds of objects and events, but a pragmatic boundary between different ways in which we interact with objects and events. Put differently, I argue that the manifest-scientific distinction, in my (...) view, can be best understood, not as a metaphysical distinction between apparent and real objects and events, or an epistemological distinction between perceptible and imperceptible objects and events, but rather as a distinction, which is not necessarily rigid over time, between distinct ways in which we collectively deal, in practice, with objects and events.

The paper focuses on the pragmatist image of humanity based on a re-reading of the philosophical “manifesto” of Wilfrid Sellars in which he became entangled in the dichotomy between “scientific” and “manifest” images. The key to solving this problem, according to the author, is the new pragmatist understanding of science as a cultural practice, which provide us with a new framework for transcending this dichotomy. By reconstructing Sellars in an anthropological rather than a scientistic way and by (...) drawing on humanistic philosophical intentions that are present both in pragmatism and in Sellars, it becomes possible to outline a concept of “science with a human face.” The purpose of all kinds of images, including scientific ones, is to serve the enrichment of human understanding and life.

This collection of new essays on the systematic thought and intellectual legacy of the American philosopher Wilfrid Sellars (1912–1989) comes at a time when Sellars’s influence on contemporary debates about mind, meaning, knowledge, and metaphysics has never been greater. Sellars was among the most important philosophers of the twentieth century, and many of his central ideas have become philosophical stock-in-trade: for example, his conceptions of the ‘myth of the given’, the ‘logical space of reasons’, and the ‘clash’ between the ‘ (...) class='Hi'>manifest and scientific images of man-in-the-world’. This volume of well-known contemporary philosophers who have been strongly influenced by Sellars – Robert Brandom, Willem deVries, Robert Kraut, Rebecca Kukla, Mark Lance, John McDowell, Ruth Millikan, James O’Shea, David Rosenthal, Johanna Seibt, and Michael Williams – critically examines the groundbreaking ideas by means of which Sellars sought to integrate our thought, perception, and rational agency within a naturalistic outlook on reality. Topics include Sellars’s inferentialist semantics and normative functionalist view of the mind; his attempted reconciliations of internalist and externalist aspects of thought, meaning, and knowledge; his novel nominalist account of abstract entities; and a speculative ‘pure process’ metaphysics of consciousness. Of particular interest is how this volume exhibits the ongoing fruitful dialogue between so-called ‘left-wing Sellarsians’, who stress Sellars’s various Kantian and pragmatist defenses of the irreducibility of normativity and rationality within the space of reasons, and ‘right-wing Sellarsians’ who defend the plausibility of Sellars’s highly ambitious and systematic scientific naturalism.

Amidst the progress being made in the various (sub-)disciplines of the behavioural and brain sciences a somewhat neglected subject is the problem of how everything fits into one world and, derivatively, how the relation between different levels of discourse should be understood and to what extent different levels, domains, approaches, or disciplines are autonomous or dependent. In this paper I critically review the most recent proposals to specify the nature of interdiscourse relations, focusing on the concept of supervenience. Ideally supervenience (...) is a relation between different discourses which has all the advantages of reduction, but without its disadvantages. I apply the more abstract considerations to two concrete cases: schizophrenia and colour. Usually an interlevel or interdiscourse relation is seen as asymmetrical: the overlaying discourse depends on the underlying discourse (and not vice versa), where the out- or un-spoken assumption is that the ultimate underlying discourse is physical. Instead I argue that scientific categories referred to in interdiscourse relations are, ultimately, dependent on common sense categories and common sense normative criteria. It is the manifest categories and common sense ideas about what is reasonable and what is right that determine the relevant categorisations at the deeper, underlying levels. I suggest that the implications of this are not merely methodological or epistemological. (shrink)

In resisting attempts to explain the unity of a whole in terms of a multiplicity of interacting parts, quantum mechanics calls for an explanatory concept that proceeds in the opposite direction: from unity to multiplicity. Being part of the Scientific Image of the world, the theory concerns the process by which (the physical aspect of) what Sellars called the Manifest Image of the world comes into being. This process consists in the progressive differentiation of an intrinsically undifferentiated entity. (...) By entering into reflexive spatial relations, this entity gives rise to (i) what looks like a multiplicity of relata if the reflexive quality of the relations is not taken into account, and (ii) what looks like a substantial expanse if the spatial quality of the relations is reified. If there is a distinctly quantum domain, it is a non-spatial and non-temporal dimension across which the transition from the unity of this entity to the multiplicity of the world takes place. Instead of being constituents of the physical world, subatomic particles, atoms, and molecules are instrumental in its manifestation. These conclusions are based on the following interpretive principle and its more direct consequences: whenever the calculation of probabilities calls for the addition of amplitudes, the distinctions we make between the alternatives lack objective reality. Applied to alternatives involving distinctions between regions of space, this principle implies that, owing to the indefiniteness of positions, the spatiotemporal differentiation of the physical world is incomplete: the existence of a real-valued spatiotemporal background is an unrealistic idealization. This guarantees the existence of observables whose values are real per se, as against “real by virtue of being indicated by the values of observables that are real per se.” Applied to alternatives involving distinctions between things, it implies that, intrinsically, all fundamental particles are numerically identical and thus identifiable with the aforementioned undifferentiated entity.

This paper reconstructs the major transformations in the Marburg neo-Kantian account of experience. By focusing on the problem of ‘conceptualism’, it traces connections between four issues that are central to the transcendental projects of the Marburg philosophers: the interpretation of Kant, the critique of experiential givenness, the account of objective cognition in science, and the relation between scientific and pre-scientific experience. My historical narrative identifies two shifts. The first is from Cohen's conceptualist answer to the threat of subjectivism (...) to Cassirer's functionalist answer to empiricism. The second is from Cassirer's conceptualism about scientific experience to his symbolic non-conceptualism about everyday perception. My reconstruction reveals the fate of neo-Kantian conceptualism to be linked to the fate of pre-scientific perception and suggests that the continuing significance of the Marburg philosophers lies in their responses to the coming apart of the manifest and the scientific image.

b>: there is no “mind-body problem”, or “hard problem of consciousness”; if there is a hard problem of something, it is the problem of reconciling the manifest and scientific images.

In this book van Fraassen develops an alternative to scientific realism by constructing and evaluating three mutually reinforcing theories.

The aim of philosophy, abstractly formulated, is to understand how things in the broadest possible sense of the term hang together in the broadest possible sense of the term. Under 'things in the broadest possible sense' I include such radically different items as not only 'cabbages and kings', but numbers and duties, possibilities and finger snaps, aesthetic experience and death. To achieve success in philosophy would be, to use a contemporary turn of phrase, to 'know one's way around' with respect (...) to all these things, not in that unreflective way in which the centipede of the story knew its way around before it faced the question, 'how do I walk?', but in that reflective way which means that no intellectual holds are barred.
