In this paper, we outline and defend a view on which in olfactory experience we can, and often do, smell ordinary things of various kinds—for instance, cookies, coffee, and cake burnings—and the olfactory properties they have. A challenge to this view are cases of smelling in the absence of the source of a smell, such as when a fishy smell lingers after the fish is gone. Such cases, many philosophers argue, show that what we perceive in olfactory experience are odour (...) objects, and not ordinary things. On behalf of our opponent, we articulate a screening-off argument based on cases of lingering smells for the thesis that we do not smell ordinary things. We then develop an alternative account of these cases that is consistent with our view. In doing so, we call into question two claims that are typically built into the notion of an odour object.

This chapter argues that olfactory experiences represent either everyday objects or ad hoc olfactory objects as having primitive olfactory properties, which happen to be uninstantiated. On this picture, olfactory experiences reliably misrepresent: they falsely represent everyday objects or ad hoc objects as having properties they do not have, and they misrepresent in the same way on multiple occasions. One might worry that this view is incompatible with the plausible claim that olfactory experiences at least sometimes justify true beliefs about the (...) world. This chapter argues that there is no such incompatibility. Since olfactory experiences reliably misrepresent, they can lead to true and justified beliefs about putatively smelly objects. (shrink)

Amodal completion is the representation of those parts of the perceived object that we get no sensory stimulation from. While amodal completion is rife and plays an essential role in all sense modalities, philosophical discussions of this phenomenon have almost entirely been limited to vision. The aim of this paper is to examine in what sense we can talk about amodal completion in olfaction. We distinguish three different senses of amodal completion – spatial, temporal and feature-based completion – and argue (...) that all three are present and play a significant role in olfaction.

While there is a growing philosophical interest in analysing olfactory experiences, the mereological structure of odours considered in respect of how they are perceptually experienced has not yet been extensively investigated. The paper argues that odours are perceptually experienced as having a mereological structure, but this structure is significantly different from the spatial mereological structure of visually experienced objects. Most importantly, in the case of the olfactory part-structure, the classical weak supplementation principle is not satisfied. This thesis is justified by (...) referring to empirical results in olfactory science concerning the human ability to identify components in complex olfactory stimuli. Further, it is shown how differences between olfactory and visual mereologies may arise from the way in which these modalities represent space. (shrink)

According to a common opinion, human olfactory experiences are significantly different from human visual experiences. For instance, olfaction seems to have only rudimentary abilities to represent space; it is not clear whether olfactory experiences have any mereological structure; and while vision presents the world in terms of objects, it is a matter of debate whether there are olfactory object-representations. This paper argues that despite these differences visual and olfactory experiences share a hierarchical subject/property structure. Within this structure, olfactorily experienced odours (...) and visual objects have the same status: they are primary subjects which unify other represented elements into perceptual units. (shrink)

The present study investigates the semantics of a dozen basic smell terms in Indonesian using data from a large corpus of written register. Examining how these smell terms lexicalize some odors but not others raises questions that are central to our understanding of the language of olfaction. How are smell terms structured? What does the structure of smell terms tell us about human behavior? By applying cluster analysis, the present study reveals that the Indonesian odor lexicon is structured based on (...) one dimension correlating with pleasantness. The large dataset of a written corpus enables the present study to reveal the differences in lexicalization and frequency: Indonesian smell terms have more negative types but more positive tokens in texts. This novel approach to investigating smell terms allows us to take a step closer toward our goal of understanding olfactory vocabulary, as data on token frequency are difficult to obtain in studies of minority languages. This key finding supports the Pollyanna Hypothesis: people tend to use positive words more often than negative words, but the negative words convey more information. (shrink)

Sensory perceptions represent things in the outside world. This mundane fact raises a major problem for naturalistic theories of content: the ‘distality problem’. In a previous paper for this journal, I presented a solution to this problem which makes central appeal to constancy mechanisms. Justin Garson, also in this journal, recently criticized my solution and suggested a Dretskean alternative to it. Here, I defend my proposal by arguing, first, that Garson's criticisms ultimately miss the mark, and secondly, that his Dretskean (...) alternative is not viable, because it faces two fundamental problems: the empirical problem and the problem of changing response functions.

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.

Philosophical research into olfaction often focuses on its limitations. We explore instead an underappreciated capacity of the sense of smell, namely, its role in interpersonal experience. To illustrate this, we examine how smell can enable continuing connections to deceased loved ones. Understanding this phenomenon requires an appreciation of, first, how olfaction's limitations can facilitate experiences of the deceased person and, second, how olfaction enables experiences of what we refer to as the ‘olfactory air’ of a person. This way of experiencing (...) someone privileges their status as an environmentally situated human animal. (shrink)

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)
