The Fragmented Mind: Working Memory Cannot Implement Consciousness, Javier Gomez-Lavin Sep 2018

The Fragmented Mind: Working Memory Cannot Implement Consciousness, Javier Gomez-Lavin

Dissertations, Theses, and Capstone Projects

In both philosophy and the sciences of the mind there is a shared commitment to the idea that there is a center—the seat of consciousness, the source of deliberation and reflection, and the core of personal identity—in the mind. My dissertation challenges this deeply entrenched view. I review the empirical literature on working memory, psychology’s best candidate for the workspace of the mind, and argue that it is not a natural kind and cannot inform these central cognitive processes. This deflationary view directly imperils many naturalistic theories of consciousness that rely on working memory, which are reviewed in this project. …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender May 2018

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Biosemiotics As An Argument For The Recontextualization Of Biological Discoveries: A Critical Analysis Of The Biosemiotic Model Of Marcello Barbieri., Augustus Morrissey Snyder May 2018

Biosemiotics As An Argument For The Recontextualization Of Biological Discoveries: A Critical Analysis Of The Biosemiotic Model Of Marcello Barbieri., Augustus Morrissey Snyder

Senior Honors Projects, 2010-2019

The primary purpose of this project was to investigate and explain the philosophical approach of biosemiotics to understanding living systems in contrast to the current scientific paradigm. Secondary goals were to evaluate the potential merits and relevance of this approach to biology and to introduce such a topic for discussion to biologists in a formal academic setting. My method consisted of critical textual analysis supplemented by analogy and biological examples where appropriate. In general, contemporary biosemiotics argues for a teleologic recontextualization of biological discoveries in practice and education. This is accomplished in a sophisticated fashion through the application and modification …

Another Scientific Revolution: Now Yielding A 'Cosmic Biology' Consistent With Natural Theology, Theodore Walker Apr 2018

Another Scientific Revolution: Now Yielding A 'Cosmic Biology' Consistent With Natural Theology, Theodore Walker

Perkins Faculty Research and Special Events

Beyond the Copernican revolution, another scientific revolution is now in process. Inspired by Sir Fred Hoyle and others, this contemporary extension of the Copernican revolution is replacing biology conceived as exclusively Earth science with biology conceived as including study of stellar evolution and cosmic evolution. Furthermore, astrobiology, panspermia, and cosmic biology (Hoyle and Wickramasinghe) are advancing in ways consistent with natural theology, especially with panentheism. Some of this was anticipated and advocated by Alfred North Whitehead, Charles Hartshorne, and other philosophers of nature.

De-Extinction And The Conception Of Species, Leonard Finkelman Jan 2018

De-Extinction And The Conception Of Species, Leonard Finkelman

Faculty Publications

Developments in genetic engineering may soon allow biologists to clone organisms from extinct species. The process, dubbed “de-extinction,” has been publicized as a means to bring extinct species back to life. For theorists and philosophers of biology, the process also suggests a thought experiment for the ongoing “species problem”: given a species concept, would a clone be classified in the extinct species? Previous analyses have answered this question in the context of specific de-extinction technologies or particular species concepts. The thought experiment is given more comprehensive treatment here. Given the products of three de-extinction technologies, twenty-two species concepts are “tested” …

Caterpillar/Basil-Plant Tandems, Paco Calvo Jan 2018

Caterpillar/Basil-Plant Tandems, Paco Calvo

Animal Sentience

According to Reber (2016), subjectivity springs from primitive life itself. Granting his non-neurocentric stance, I shall try to show that his framework falls prey to zoocentric preconceptions that divest certain non-animal life-forms of mentality. There is no reason to exclude the possibility that plants have evolved different structures that underlie their own subjective experiences, all according to Reber’s model. It is the degree of phenotypic flexibility and integration that we observe in the behavioral repertoire of plants that may end up supporting their capacity for subjective experience. This remains an open empirical question.

Animal Suicide: An Account Worth Giving?, Irina Mikhalevich Jan 2018

Animal Suicide: An Account Worth Giving?, Irina Mikhalevich

Animal Sentience

Peña-Guzmán (2017) argues that empirical evidence and evolutionary theory compel us to treat the phenomenon of suicide as continuous in the animal kingdom. He defends a “continuist” account in which suicide is a multiply-realizable phenomenon characterized by self-injurious and self-annihilative behaviors. This view is problematic for several reasons. First, it appears to mischaracterize the Darwinian view that mind is continuous in nature. Second, by focusing only on surface-level features of behavior, it groups causally and etiologically disparate phenomena under a single conceptual umbrella, thereby reducing the account’s explanatory power. Third, it obscures existing analyses of suicide in biomedical ethics and …

Measured Soil Hydraulic Properties As Rzwqm2 Input To Simulate Soil Water Dynamics And Crop Evapotranspiration, Saadi Sattar Shahadha Jan 2018

Measured Soil Hydraulic Properties As Rzwqm2 Input To Simulate Soil Water Dynamics And Crop Evapotranspiration, Saadi Sattar Shahadha

Theses and Dissertations--Plant and Soil Sciences

Agricultural system models integrate many different processes that cannot all be measured in field experiments and help quantify soil water dynamics, crop evapotranspiration, and crop growth with high temporal resolution. Understanding soil water dynamics and crop evapotranspiration is essential to improve agricultural management of field crops. For example, the interaction between nitrogen application rate and water dynamics is not sufficiently understood. In most cases, model simulations deviate from field measurements, especially when model input parameters are indirectly and unspecifically derived. The extent to which measured soil hydraulic property inputs decrease the discrepancy between measured and simulated soil water status is …
