Effects of Pasteurization (Heating) on Milled Flaxseed Quality
Current food industry practices include the use of pasteurization (heat treatment) as a
means to reduce the microbial counts of flaxseed (Linum usitatissimum). Flaxseed was
pasteurized using a dry air heat treatment of 148 °C for 16.25 minutes and the oxidative stability
was observed over a 20 week storage period. Flaxseed quality was measured using peroxide
value, percent free fatty acid (as oleic), and propanal content. Peroxide values of the pasteurized
milled flaxseed were found to significantly increase (P †0.05) by week 2. Propanal formation
coincided with peroxide value development over 20 weeks of storage. Pasteurized flaxseed
milled under refrigerated temperatures (10 â 18 °C) did not exhibit any significant (P > 0.05)
improvement in oxidative stability. Flaxseed pasteurization at 148 °C for 16.25 minutes using
dry heat was found to be detrimental to the oxidative stability flaxseed once milled
The Cognitive Phenomenology Argument for Disembodied AI Consciousness
In this chapter I offer two novel arguments for what I call strong primitivism about cognitive phenomenology, the thesis that there exists a phenomenology of cognition that is neither reducible to, nor dependent upon, sensory phenomenology. I then contend that strong primitivism implies that phenomenal consciousness does not require sensory processing. This latter contention has implications for the philosophy of artificial intelligence. For if sensory processing is not a necessary condition for phenomenal consciousness, then it plausibly follows that AI consciousness (assuming that it is possible) does not require embodiment. The overarching goal of this paper is to show how different topics in the analytic philosophy of mind can be brought to bear on an important issue in the philosophy of artificial intelligence
The Metaverse: Virtual Metaphysics, Virtual Governance, and Virtual Abundance
In his article âThe Metaverse: Surveillant Physics, Virtual Realist Governance, and the Missing Commons,â Andrew McStay addresses an entwinement of ethical, political, and metaphysical concerns surrounding the Metaverse, arguing that the Metaverse is not being designed to further the public good but is instead being created to serve the plutocratic ends of technology corporations. He advances the notion of âsurveillant physicsâ to capture this insight and introduces the concept of âvirtual realist governanceâ as a theoretical framework that ought to guide Metaverse design and regulation. This commentary article primarily serves as a supplementary piece rather than a direct critique of McStayâs work. First, I flag certain understated or overlooked nuances in McStayâs discussion. Then, I extend McStayâs discussion by juxtaposing a Lockean inspired argument supporting the property rights of Metaverse creators with an opposing argument advocating for a Metaverse user's âright to virtual abundance,â informed by the potential of virtual reality technology to eliminate scarcity in virtual worlds. Contrasting these arguments highlights the tension between corporate rights and social justice in the governance of virtual worlds and bears directly on McStayâs assertion that there is a problem of the missing commons in the early design of the Metaverse
Online Echo Chambers, Online Epistemic Bubbles, and Open-Mindedness
This article is an exercise in the virtue epistemology of the internet, an area of applied virtue epistemology that investigates how online environments impact the development of intellectual virtues, and how intellectual virtues manifest within online environments. I examine online echo chambers and epistemic bubbles (Nguyen 2020, Episteme 17(2), 141â61), exploring the conceptual relationship between these online environments and the virtue of open-mindedness (Battaly 2018b, Episteme 15(3), 261â82). The article answers two key individual-level, virtue epistemic questions: (Q1) How does immersion in online echo chambers and epistemic bubbles affect the cultivation and preservation of open-mindedness, and (Q2) Is it always intellectually virtuous to exhibit open-mindedness in the context of online echo chambers and epistemic bubbles? In response to Q1, I contend that both online echo chambers and online epistemic bubbles threaten to undermine the cultivation and preservation of open-mindedness, albeit via different mechanisms and to different degrees. In response to Q2, I affirm that both a deficiency and an excess of open-mindedness can be virtuous in these online environments, depending on the epistemic orientation of the digital user
Augmented Reality, Augmented Epistemology, and the Real-World Web
Augmented reality (AR) technologies function to âaugmentâ normal perception by superimposing virtual objects onto an agentâs visual field. The philosophy of augmented reality is a small but growing subfield within the philosophy of technology. Existing work in this subfield includes research on the phenomenology of augmented experiences, the metaphysics of virtual objects, and different ethical issues associated with AR systems, including (but not limited to) issues of privacy, property rights, ownership, trust, and informed consent. This paper addresses some epistemological issues posed by AR systems. I focus on a near-future version of AR technology called the Real-World Web, which promises to radically transform the nature of our relationship to digital information by mixing the virtual with the physical. I argue that the Real-World Web (RWW) threatens to exacerbate three existing epistemic problems in the digital age: the problem of digital distraction, the problem of digital deception, and the problem of digital divergence. The RWW is poised to present new versions of these problems in the form of what I call the augmented attention economy, augmented skepticism, and the problem of other augmented minds. The paper draws on a range of empirical research on AR and offers a phenomenological analysis of virtual objects as perceptual affordances to help ground and guide the speculative nature of the discussion. It also considers a few policy-based and designed-based proposals to mitigate the epistemic threats posed by AR technology
The Extended Mind Argument Against Phenomenal Intentionality
This paper offers a novel argument against the phenomenal intentionality thesis (or PIT for short). The argument, which Iâll call the extended mind argument against phenomenal intentionality, is centered around two claims: the first asserts that some source intentional states extend into the environment, while the second maintains that no conscious states extend into the environment. If these two claims are correct, then PIT is false, for PIT implies that the extension of source intentionality is predicated upon the extension of phenomenal consciousness. The argument is important because it undermines an increasingly prominent account of the nature of intentionality. PIT has entered the philosophical mainstream and is now a serious contender to naturalistic views of intentionality like the tracking theory and the functional role theory. The extended mind argument against PIT challenges the popular sentiment that consciousness grounds intentionality
Neuromedia, Cognitive Offloading, and Intellectual Perseverance
This paper engages in what might be called anticipatory virtue epistemology, as it anticipates some virtue epistemological risks related to a near-future version of brain-computer interface technology that Michael Lynch (2014) calls 'neuromedia.' I analyze how neuromedia is poised to negatively affect the intellectual character of agents, focusing specifically on the virtue of intellectual perseverance, which involves a disposition to mentally persist in the face of challenges towards the realization of oneâs intellectual goals. First, I present and motivate what I call âthe cognitive offloading argumentâ, which holds that excessive cognitive offloading of the sort incentivized by a device like neuromedia threatens to undermine intellectual virtue development from the standpoint of the theory of virtue responsibilism. Then, I examine the cognitive offloading argument as it applies to the virtue of intellectual perseverance, arguing that neuromedia may increase cognitive efficiency at the cost of intellectual perseverance. If used in an epistemically responsible manner, however, cognitive offloading devices may not undermine intellectual perseverance but instead allow us to persevere with respect to intellectual goals that we find more valuable by freeing us from different kinds of menial intellectual labor
HoloFoldit and Hologrammatically Extended Cognition
How does the integration of mixed reality devices into our cognitive practices impact the mind from a metaphysical and epistemological perspective? In his innovative and interdisciplinary article, âMinds in the Metaverse: Extended Cognition Meets Mixed Realityâ (2022), Paul Smart addresses this underexplored question, arguing that the use of a hypothetical application of the Microsoft HoloLens called âthe HoloFolditâ represents a technologically high-grade form of extended cognizing from the perspective of neo-mechanical philosophy. This short commentary aims to (1) carve up the conceptual landscape of possible objections to Smartâs argument and (2) elaborate on the possibility of hologrammatically extended cognition, which is supposed to be one of the features of the HoloFoldit case that distinguishes it from more primitive forms of cognitive extension. In tackling (1), I do not mean to suggest that Smart does not consider or have sufficient answers to these objections. In addressing (2), the goal is not to argue for or against the possibility of hologrammatically extended cognition but to reveal some issues in the metaphysics of virtual reality upon which this possibility hinges. I construct an argument in favor of hologrammatically extended cognition based on the veracity of virtual realism (Chalmers, 2017) and an argument against it based on the veracity of virtual fctionalism (McDonnell and Wildman, 2019)
