We perceive smells as perduring complex entities within a distal array that might be conceived of as smellscapes. However, the philosophical orthodoxy of Odor Theories has been to deny that smells are perceived as having a distal location. Recent challenges have been mounted to Odor Theories’ veracity in handling the timescale of olfactory perception, how it individuates odors as a distal entities, and their claim that olfactory perception is not spatial. The paper does not aim to dispute these criticisms. Rather, (...) what will be shown is that Molecular Structure Theory, a refinement of Odor Theory, can be further developed to handle these challenges. The theory is further refined by focusing on distal perception that requires considering the perceptual object as mereologically complex persisting odor against a background scene conceived of as a smellscape. What will be offered is an expansion of Molecular Structure Theory to account for distal smell perception within natural environments. (shrink)

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)

Although vision is the de facto model system of consciousness research, studying olfactory consciousness has its own advantages, as this collection of articles emphatically demonstrates. One advantage of olfaction is its computational and phenomenological simplicity, which facilitates the identification of basic principles. Other researchers study olfactory consciousness not because of its simplicity, but because of its unique features. Together, olfaction's simplicity and its distinctiveness make it an ideal system for testing theories of consciousness. In this research topic, the results of (...) recent research into olfactory consciousness are presented. (shrink)

The chapter unfolds in the following sections. The first section exam- ines the reasons for claiming that olfactory perception is spatially unstruc- tured and our experience of smells has an abstract structure. The second section elucidates the further arguments that olfaction cannot generate figure-ground segregation. The third section assesses the conclusion that olfactory perception and experience cannot solve the MPP. Following the overview of the many problems inherent to distal olfactory percep- tion, MST will be introduced as an alternative perspective (...) that allows for figure-ground segregation and perceiving multiple olfactory objects within an array. The chapter then concludes by replying to the shared argument that olfactory distal perception does not have the requisite res- olution to resolve the many properties problem. (shrink)

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.

Quality-space theory (QST) explains the nature of the mental qualities distinctive of perceptual states by appeal to their role in perceiving. QST is typically described in terms of the mental qualities that pertain to color. Here we apply QST to the olfactory modalities. Olfaction is in various respects more complex than vision, and so provides a useful test case for QST. To determine whether QST can deal with the challenges olfaction presents, we show how a quality space (QS) could be (...) constructed relying on olfactory perceptible properties and the olfactory mental qualities then defined by appeal to that QS of olfactory perceptible properties. We also consider how to delimit the olfactory QS from other modalities. We further apply QST to the role that experience plays in refining our olfactory discriminative abilities and the occurrence of olfactory mental qualities in non-conscious olfactory states. QST is shown to be fully applicable to and useful for understanding the complex domain of olfaction. (shrink)

I begin by discussing an objection often lodged against higher-order theories of consciousness. The objection is that those theories do not preclude consciousness from misrepresenting the mental properties of our conscious states. I argue that there are several reasons why this objection cannot succeed. Sam Coleman agrees that the objection fails, but sees it as pointing to a related objection, which he argues poses difficulties the higher-order theorist cannot avoid. His solution is a variant theory of consciousness that invokes mental (...) quotation in the content of a higher-order awareness. I’ll argue that mental quotation cannot be understood in any way that helps with the objection. I’ll argue also that the objection Coleman articulates is question begging, since it in effect simply channels a first-order approach to consciousness, and has no independent basis apart from that. Resumo: Começo por discutir uma objeção muitas vezes apresentada contra as teorias da consciência de ordem superior. A objeção é que essas teorias não impedem a consciência de representar de modo errôneo as propriedades mentais de nossos estados conscientes. Eu argumento que existem várias razões pelas quais essa objeção não pode ter sucesso. Sam Coleman concorda que a objeção falha, mas a vê como apontando para uma objeção relacionada, que ele argumenta apresentar dificuldades que o teórico do pensamento de ordem superior não pode evitar. Sua solução é uma variante desta teoria, que invoca a “citação mental” como conteúdo da consciência de ordem superior. Eu argumentarei que a citação mental não pode ser entendida de alguma forma que satisfaça tal objeção. Argumentarei também que a objeção que Coleman articula incorre em petição de princípio, uma vez que, na prática, ela simplesmente escolhe uma abordagem de primeira ordem para a consciência, e não tem nenhuma justificativa independente para isso.
