While the objects of olfaction are intuitively individuated by reference to the ordinary objects from which they arise, this intuition does not accurately capture the complex nature of smells. Smells are neither ordinary three-dimensional objects, nor Platonic vapors, nor odors. Rather, smells are the molecular structures of chemical compounds within odor plumes. Molecular Structure Theory is offered as an account of smells, which can explain the nature of the external object of olfactory perception, what we experience as olfactory objects, and (...) what determines the olfactory quality of smells by which we can demarcate the spatiotemporal boundaries of smells.

There is consensus within the chemosciences that olfactory perception is of the molecular structure of chemical compounds, yet within philosophical theories of smell there is little agreement about the nature of smell. The paper critically assesses the current state of debate regarding smells within philosophy in the hopes of setting it upon firm scientific footing. The theories to be covered are: Naïve Realism, Hedonic Theories, Process Theory, Odor Theories, and non-Objectivist Theories. The aforementioned theories will be evaluated based (...) on their explanations of the (a) the olfactory quality of a smell, (b) smells as distal entities, and (c) our experience of smells as intentional objects. The paper concludes with a defense of Molecular Structure Theory that demonstrating its superiority in accounting for each of these three aspects of smell. (shrink)

Most philosophers consider olfactory experiences to be very poor in comparison to other sense modalities. And because olfactory experiences seem to lack the spatial content necessary to object perception, philosophers tend to maintain that smell is purely sensational or abstract. I argue in this paper that the apparent poverty and spatial indeterminateness of odor experiences does not reflect the “subjective” or “abstract” nature of smell, but only that smell is not directed to particular things. According to the (...) view defended in this paper, odors are properties of stuffs. This view, motivated by several arguments grounded in the phenomenology of olfactory experience, explains in particular why odors appear to be located both in the air around our nose and in the objects from which they emanate. It also explains the power of smell in the task of discriminating chemical compounds. (shrink)

Objects are central to perception and our interactions with the world. We perceive the world as parsed into discrete entities that instantiate particular properties, and these items capture our attention and shape how we interact with the environment. Recently there has been some debate about whether the sense of smell allows us to perceive odours as discrete objects, with some suggesting that olfaction is aspatial and doesn’t allow for object-individuation. This paper offers two empirically tractable criteria for assessing whether (...) particular objects are exhibited in perceptual experience— susceptibility to figure-ground segregation and perceptual constancies—and argues that these criteria are fulfilled by olfactory perception, and thus there are olfactory objects. I argue that there are, in fact, two different ways that olfaction allows for figure-ground segregation. First, I look at various Gestalt grouping principles, which are thought to govern when features are perceived as grouped into structured wholes, segregated from everything around them. I argue that these principles apply to olfactory experience, providing evidence of non-spatial figure-ground segregation. Second, I defend the contentious idea that a spatial variety of figure-ground segregation can also occur in olfaction. To see this, however, we need to look to empirical evidence showing that tactile stimulation and bodily movements play a crucial role in olfactory phenomenology. Finally, I draw on empirical evidence and olfactory phenomenology to argue that there are perceptual constancies in olfactory experience, allowing us to perceive odours as coherent objects that survive shifts in our perspectives on the world.

Humans are poorer at identifying smells and communicating about them, compared to othersensory domains. They also cannot easily organise odour sensations in a general conceptual space like with colours. We challenge the conclusion that there is no olfactory conceptual map at all. Instead we propose a new framework, with local conceptual spaces.

I sketch and defend an imperativist treatment of the phenomenology associated with disgusting smells. This treatment, I argue, allows us to make better sense than other intentionalist alter-natives both of the neuroanatomy of olfaction, and of a natural pre-theoretical stance regarding the sense of smell.

It is arguably the case that olfactory system contains two senses that share the same type of stimuli, sensory transduction mechanism, and processing centers. Yet, orthonasal and retronasal olfaction differ in their types of perceptible objects as individuated by their sensory qualities. What will be explored in this paper is how the account of orthonasal smell developed in the Molecular Structure Theory of smell can be expanded for retronasal olfaction (Young, 2016, 2019a-b, 2020). By considering the object of (...) olfactory perception to be the molecular structure of chemical compounds composing odor plumes, Molecular Structure Theory provides a means for determining an odor’s olfactory quality, how odors can be identified and individuated, and how we perceive smellscapes. Surveying the differences between orthonasal and retronasal olfaction provides the basis for the central argument of the paper that the perceptible objects we refer to as smells and individuated on the basis of their olfactory qualities are only relative to orthonasal olfaction. Retronasal olfaction it is speculatively concluded might play an essential role in our perception of flavorful objects. (shrink)

Humans are poorer at identifying smells and communicating about them, compared to other sensory domains. They also cannot easily organize odor sensations in a general conceptual space, where geometric distance could represent how similar or different all odors are. These two generalities are more or less accepted by psychologists, and they are often seen as connected: If there is no conceptual space for odors, then olfactory identification should indeed be poor. We propose here an important revision to this conclusion: We (...) believe that the claim that there is no odor space is true only if by odor space, one means a conceptual space representing all possible odor sensations, in the paradigmatic sense used for instance for color. However, in a less paradigmatic sense, local conceptual spaces representing a given subset of odors do exist. Thus the absence of a global odor space does not warrant the conclusion that there is no olfactory conceptual map at all. Here we show how a localist account provides a new interpretation of experts and cross‐cultural categorization studies: Rather than being exceptions to the poor olfactory identification and communication usually seen elsewhere, experts and cross‐cultural categorization are here taken to corroborate the existence of local conceptual spaces.

Qualitative-consciousness arises at the sensory level of olfactory processing and pervades our experience of smells to the extent that qualitative character is maintained whenever we are aware of undergoing an olfactory experience. Building upon the distinction between Access and Phenomenal Consciousness the paper offers a nuanced distinction between Awareness and Qualitative-consciousness that is applicable to olfaction in a manner that is conceptual precise and empirically viable. Mounting empirical research is offered substantiating the applicability of the distinction to olfaction and showing (...) that olfactory qualitative-consciousness can occur without awareness, but any olfactory state that we are aware of being in is always qualitative. Evidence that olfactory sensory states have a qualitatively character in the absence of awareness derives from research on mate selection, the selection of social preference for social interaction and acquaintances, as well as the role of olfactory deficits in causing affective disorders. Furthermore, the conservation of secondary processing measures of olfactory valence during olfactory imagery experiments provides verification that olfactory awareness is always qualitatively conscious—all olfactory consciousness smells phenomenal. (shrink)

The thesis that smells are objective and independent of perceivers may seem to be in tension with the phenomenon of perceptual variation. In this paper, I argue that there are principled reasons to think that perceptual variation is not a threat to objectivism about smells and is indeed integral to our perceptual relation to the objective world. I first distinguish various kinds of perceptual variation, and argue that the most challenging cases for the objectivist are those where an odourant smells (...) different in different conditions or to different perceivers but the odourant does not change, and there is neither misperception nor a simple failure to perceive a smell. I then argue that there is an independently plausible conception of olfactory experience on which even these challenging cases do not pose a threat to objectivism about smells. Following Kalderon’s work in the domain of colour perception, I argue that olfactory perception provides us with a partial perspective on the smells around us, where this perspective is constrained by the conditions of perception as well as by features of the perceiver. Within this framework, we can allow that perceivers with different sensitivities, or the same perceiver in different conditions, genuinely perceive the same objective smell even though this smell appears different to them. In turn, smells are best understood as qualitatively complex entities, different aspects of which can become perceptually available in different conditions and to different perceivers. (shrink)

The sense of smell occupies a peculiar intermediate position within Aristotle's theory of sense perception: odours, like colours and sounds, are perceived at a distance through an external medium of air or water; yet in their nature they are intimately related to flavours, the proper objects of taste, which for Aristotle is a form of touch. In this paper, I examine Aristotle's claims about odour and smell, especially in De Anima II.9 and De Sensu 5, to see what (...) light they shed on his theory of sense perception more generally. In the first half, I argue that neither of the two most influential recent ways of understanding Aristotle's theory of perception can adequately account for what he says about the sense of smell. In the second half, I offer my own positive account, considering and resolving various puzzles raised by Aristotle's claims about the nature of odour and its relation to flavour. Finally, I conclude that Aristotle's discussions of odour and smell suggest a plausible and interesting way of understanding the relationship, on his view, between ordinary, material changes in the sense organs and the activation of the capacity to perceive, considered merely as such.

Much of the philosophical work on perception has focused on vision. Recently, however, philosophers have begun to correct this ‘tunnel vision’ by considering other modalities. Nevertheless, relatively little has been written about the chemical senses—olfaction and gustation. The focus of this paper is olfaction. In this paper, I consider the question: does human olfactory experience represents objects as thus and so? If we take visual experience as the paradigm of how experience can achieve object representation, we might think that the (...) answer to this question is no. I argue that olfactory experience does indeed represent objects—just not in a way that is easily read from the dominant visual case. (shrink)

Researching user experience in smell perception I will contribute to a methodological approach of generating meaning creating knowledge and awareness in a culture of senses, understanding smell as a storying element in myth corresponding with design. In my paper I address images in Homeric language triggering mythical ‘smell scapes’. I examine smell perception in the perspective of narrative elements reflecting interactions of actants and agency in actor networks: Addressing myth as a challenge of narrative framings of (...) two levels, i.e. media in smell and language, I suggest that smell research is not only a way to understanding media (McLuhan), but also to a new way of designing research tools that contribute to cultivate odor perception as a cultural quality of space and time perception.

U tekstu autor nastoji istražiti Wittgensteinove pojmove djelovanja, prakse i pragmatizma iz njegove knjige O izvjesnosti. Nastoji se ocrtati kriterij Wittgensteinove analize izvjesnosti i definirati ključne pojmove poput slike svijeta, prakse, izvjesnosti i opravdanja. Analiza pokazuje da Wittgenstein primjenjuje specifičan oblik pragmatičnoga rješenja problema opravdanja, koji se na kraju krajeva može i treba nazvati nekom vrstom pragmatizma. To je predmet prvog i drugog dijela teksta. U trećemu se dijelu pokazuje primjena ove pragmatične teorije opravdanja na Wittgensteinovo opovrgavanje skepticizma. Autor sugerira (...) da je njegova pragmatična analiza izvjesnosti prikladno sredstvo za opovrgavanje skepticizma.

U zaključku autor primjenjuje ovo antiskeptičko rješenje na tzv. problem slijeđenja pravila i pokazuje da postoje dalekosežne posljedice ove interpretacije Wittgensteinova kasnog djela na njegova shvaćanja jezika, učenja, ontologije i znanja.In the text the author tries to investigate Wittgenstein’s notions of action, practice and pragmatism in his book On Certainty. An attempt is made to sketch the criterion of Wittgenstein’s analysis of certainty and to define the crucial concepts such as world-picture, practice, certainty and justification.

This is the subject of the first and the second part of the text. The third part shows the application of this pragmatic theory of justification to Wittgenstein’s refutation of scepticism. The author suggests that his pragmatic analysis of certainty presents an adequate means for the refutation of scepticism. However, his anti-scepticism is situated in the tradition of common sense and ordinary language philosophy and epistemology . In the conclusion the author applies this anti-sceptical solution to the so called rule-following problem and shows that there are some far reaching consequences of this interpretation of Wittgenstein’s later work to his position on language, learning, ontology and knowledge.

The dual role of olfaction in both smelling and tasting, i.e. flavour perception, makes it an important test case for philosophical theories of sensory individuation. Indeed, the psychologist Paul Rozin claimed that olfaction is a “dual sense”, leading some scientists and philosophers to propose that we have not one, but two senses of smell: orthonasal and retronasal olfaction. In this paper I consider how best to understand Rozin’s claim, and upon what grounds one might judge there to be one (...) or two distinct olfactory modalities. I conclude that while Rozin may be right that humans have dual occurrences of an olfactory ‘sense’, the concept of a sense-modality, and hence the ‘sense’ of smell, is ambiguous between two different notions: a physiological sensory channel and an experiential modality, along the lines suggested by J. J. Gibson. Furthermore, recognising that these are complementary rather than competing conceptions of a sense-modality enables the formulation of a powerful ‘dual-concept’ framework for posing and addressing questions concerning the complex architecture of human multisensory experience.

Conscious experience of the sensation of smell provides exemplars of the sensation exhibiting to us what it is like. These exemplars of experiences can become vehicles or terms of representation and meaning. I call this exemplar representation and the process exemplarization. The notion of exemplarization is indebted to Hume and Goodman. I modify the notion here to apply to the sensation of smell. Exemplar representation differs from verbal representation because the exemplar, like a sample, exhibits what the represented (...) items smell like, a perfume, a spice, or an animal. The exemplar represents the sensation and, at the same, represents external objects, my example is the spray of a skunk, by exhibiting what a skunk smells like. The exemplar is part of the meaning and conception of the external object. This solves the problem, as Reid insisted, of how experience of smell justifies perceptual belief in the existence of external objects. The meaning of thought and discourse about external objects is not exhausted by the exemplarization of the sensation of smell, but the exemplar becomes evidence of their existence as part of the meaning of what they smell like. The evidence and justification of the exemplar is fallible and defeasible. However, exemplar justification, when undefeated by error in the way it coheres with a background system, becomes knowledge of the external world. (shrink)

In philosophical discussions of the secondary qualities, color has taken center stage. Smells, tastes, sounds, and feels have been treated, by and large, as mere accessories to colors. We are, as it is said, visual creatures. This, at least, has been the working assumption in the philosophy of perception and in those metaphysical discussions about the nature of the secondary qualities. The result has been a scarcity of work on the “other” secondary qualities. In this paper, I take smells and (...) place them front and center. I ask: What are smells? For many philosophers, the view that colors can be explained in purely physicalistic terms has seemed very appealing. In the case of smells, this kind of nonrelational view has seemed much less appealing. Philosophers have been drawn to versions of relationalism—the view that the nature of smells must be explained (at least in part) in terms of the effects they have on perceivers. In this paper, I consider a contemporary argument for this view. I argue that nonrelationalist views of smell have little to fear from this argument. (shrink)

Smell 'sensations' are among the most mysterious of conscious experiences, and have been cited in defense of the thesis that the character of perceptual experience is independent of the physical events that seem to give rise to it. Here we review the scientific literature on olfaction, and we argue that olfaction has a distinctive profile in relation to the other modalities, on four counts: in the physical nature of the stimulus, in the sensorimotor interactions that characterize its use, in (...) the structure of its intramodal distinctions and in the functional role that it plays in people's behaviour. We present two thought experiments in which we detail what would be involved in transforming sounds into smells, and also smells into colours. Through these thought-experiments, we argue that the experiential character of smell derives precisely from the structural features of olfaction, and that an embodied account of olfactory phenomenology is called for.

Abstract:Qu Yuan (c. 340–278 BC) is often called “the first Chinese poet,” because the primary work attributed to him, Li sao (“Sublimating Sorrow”), is the first in the tradition to evoke a distinctive persona engaged in self-reflection and personal narrative. To explain why this story of frustrated political ambition became arguably the first instance of Chinese autobiography or life writing, this paper uses the notion of “biological handicap,” proposed by Amotz Zahavi. As a peacock’s cumbersome tail feathers reduce its individual (...) chances of survival but communicate valuable information to potential mates, the Li Sao’s poetic persona uses images its audience understood as external marks of invisible, spiritual potency, like long eyebrows and fragrant adornments, to evoke unfulfilled political potential, resulting in an early model of literary interiority.

_Human Kindness and the Smell of Warm Croissants _makes philosophy fun, tactile, and popular. Moral thinking is simple, Ruwen Ogien argues, and as inherent as the senses. In our daily experiences, in the situations we confront and in the scenes we witness, we develop an understanding of right and wrong as sophisticated as the moral outlook of the world's most gifted philosophers. By drawing on this knowledge to navigate life's most perplexing problems, ethics becomes second nature. Ogien explores, through (...) experimental philosophy and other methods, the responses nineteen real-world conundrums provoke. Is a short, mediocre life better than no life at all? Is it acceptable to kill a healthy person so his organs can save five others? Would you swap a "natural" life filled with frustration, disappointment, and partial success for a world in which all of your needs are met, but through artificial and mechanical means? Ogien doesn't seek to show how difficult it is to determine right from wrong or how easy it is for humans to become monsters or react like saints. Helping us tap into the wisdom and feeling we already possess in our ethical "toolboxes," Ogien instead encourages readers to question moral presuppositions and rules; embrace an intuitive sense of dignity, virtue, and justice; and pursue a pluralist ethics suited to the principles of human kindness.

Building on the computer science concept of code smells, we initiate the study of law smells, i.e., patterns in legal texts that pose threats to the comprehensibility and maintainability of the law. With five intuitive law smells as running examples—namely, duplicated phrase, long element, large reference tree, ambiguous syntax, and natural language obsession—, we develop a comprehensive law smell taxonomy. This taxonomy classifies law smells by when they can be detected, which aspects of law they relate to, and how (...) they can be discovered. We introduce text-based and graph-based methods to identify instances of law smells, confirming their utility in practice using the United States Code as a test case. Our work demonstrates how ideas from software engineering can be leveraged to assess and improve the quality of legal code, thus drawing attention to an understudied area in the intersection of law and computer science and highlighting the potential of computational legal drafting.

In this paper I argue that olfactory experience, like visual experience, is exteroceptive: it seems to one that odours, when one smells them, are external to the body, as it seems to one that objects are external to the body when one sees them. Where the sense of smell has been discussed by philosophers, it has often been supposed to be non-exteroceptive. The strangeness of this philosophical orthodoxy makes it natural to ask what would lead to its widespread acceptance. (...) I argue that philosophers have been misled by a visuocentric model of what exteroceptivity involves. Since olfaction lacks the spatial features that make vision exteroceptive the conclusion that olfaction is nonexteroceptive can appear quite compelling, particularly in the absence of an alternative model of exteroceptivity appropriate to olfaction. I offer a model according to which odours seem to be external to the body because they seem to be brought into the nose from without by sniffing and breathing through the nostrils. I argue that some natural-seeming objections to this model rely on substantive assumptions about how the senses are distinguished from one another, and how perceptual experience is put together out of its modality-specific parts, that require defence.

I consider the role of psychology and other sciences in telling us about our senses, via the issue of whether empirical findings show us that flavours are perceived partly with the sense of smell. I argue that scientific findings do not establish that we're wrong to think that flavours are just tasted.

Any comprehensive theory of smell must account for (1) the distal nature of smells, (2) how smells are represented within odorous experiences, and (3) the olfactory quality of smells. Molecular Structure Theory (MST) and more recent developments arguably provide an account of these questions. It has been argued that we can account for (3) olfactory quality in light of the molecular structure of chemical compounds that compose the odorant plumes which we perceive as (1) distal mereological complex perduring objects (...) within smellscapes. Additionally it has been argued that olfactory perceptual and cognitive processing implements (2) a non-conceptual representational system that is incompatible with the compositional format employed by semantic processing systems. The theory I have been developing generates a comprehensive account of smell by treating these as nested issues inherent in for the nature of smell (Young, 2016, 2019a-d, 2020). However, the chapter assesses the adequacy of my theory by addressing recent criticisms of MST’s account of olfactory quality (Barwich 2014, 2015; Keller 2015, 2017), the need for positing odor objects (Barwich 2019), and a possible incompatibility between my account of synchronic odor perception in MST and more recent developments focusing on the diachronic experiences of smellscapes.

Smells are often said to be ineffable, and linguistic research shows that languages like English lack a dedicated olfactory lexicon. Starting from this evidence, I propose an account of how we talk about smells in English. Our reports about the way things smell are comparative: When we say that something smells burnt or like roses, we characterise the thing's smell by noting its similarity to the characteristic smells of certain odorous things (burnt things, roses). The account explains both (...) the strengths and limitations of our smell discourse, and has implications for philosophical discussions of the relation between language and appearances. (shrink)

In the present article, I review some evidence that shows how body odor disgust sensitivity plays a central role in the so-called behavioral immune system, a set of processes aimed at detecting, emotionally reacting, and behaviorally avoiding pathogen threats. I also report empirical evidence on how the BODS relates to social attitudes such as authoritarianism, xenophobia, and condemnation of “impure” moral violations. This research is interpreted from an Evolutionary psychology framework.

Short piece for The Philosophers' Magazine on why philosophers should pay attention to olfaction.

There are many accounts of representation in the philosophical literature. However, regarding olfaction, Burge’s (2010) account is widely endorsed. According to his account, perceptual representation is always of an objective reality, that is, perception represents objects as such. Many authors presuppose this account of representation and attempt to show that the olfactory system itself issues in representations of that sort. The present paper argues that this myopia is a mistake and, moreover, that the various arguments in favor of olfactory objects (...) fail. Yet, by taking seriously a minimal notion of representation, adopted from Shea (2018), we can see that the olfactory system is representational after all even if it doesn’t represent objects as such. That is, olfaction issues in minimal representations. Crucially, however, this paper will conclude with an argument to the effect that olfactory object files (objectual representations of olfactory objectual properties) are constructed by interactions between various mental systems. The claim to be defended is that objectual representations of olfactory objects are constructed when minimal olfactory content is embedded in object-files that contain other non-olfactory properties that meet Burge’s criteria for representation. Some extant work on feature-binding, attention, and object-files will be introduced to support the suggestion. (shrink)

Mental Imagery, whereby we experience aspect of a perceptual scene or perceptual object in the absence of direct sensory stimulation is ubiquitous. Often the existence of mental imagery is demonstrated by asking one’s reader to volitionally generate a visual object, such as closing ones eyes and imagining an apple. However, mental imagery also arises in auditory, tactile, interoceptive, and olfactory cases. A number of influential philosophical theories have attempted to explain mental imagery in terms of belief-based forms of representation using (...) the Dependence Thesis, dependence upon means of access, such as enactivism, or in terms of the similarity of content with perceptual processing. The focus of this paper concerns the later approach and in particular assessing if Nanay’s promissory note that his theory is applicable to modalities other than vision, such as smell, seems likely to be of theoretical tender. The thesis argued for in this paper is that olfactory imagery exists and is best accounted for by considering it as a type of perceptual processing with a unique representational format relative to the olfactory perceptual modality. The paper concludes by summarizing the applicability of Nanay’s theory of mental imagery for olfaction and suggests some further issues that arise when transitioning to multi-modal mental imagery.
