The thesis is that contrary to the received popular wisdom, the combination of David Hume's sceptical enquiry and Charles Darwin's provision of an alternative theoretical framework to the then current paradigm of natural theology did not succeed in defeating the design argument. I argue that William Paley's work best represented the status quo in the philosophy of biology circa 1800 and that with the logical mechanisms provided us by William Dembski in his seminal work on probability, there is a strong argument for thr work of Michael Behe to stand in a similar position today to that of Paley two centuries ago. The argument runs as follows: In Sections 1 and 2 of Chapter 1 I introduce the issues. In Section 3 I argue that William Paley's exposition of the design argument was archetypical of the natural theology school and that given Hume's already published criticism of the argument, Paley for one did not feel the design argument to be done for. I further argue in Section 4 that Hume in fact did no such thing and that neither did he see himself as having done so, but that the design argument was weak rather than fallacious. In Section 5 I outline the demise of natural theology as the dominant school of thought in the philosophy of biology, ascribing this to the rise of Darwinism and subsequently neo-Darwinism. I argue that design arguments were again not defeated but went into abeyance with the rise of a new paradigm associated with Darwinism, namely methodological naturalism. In Chapter 2 I advance the project by a discussion of William Dembski's formulation of design inferences, demonstrating their value in both everyday and technical usage. This is stated in Section 1. In Sections 2 and 3 I discuss Dembski's treatment of probability, whilst in Section 4 I examine Dembski's tying of different levels of probability to different mechanisms of explanation used in explicating the world. Section 5 is my analysis of the logic of the formal statement of the design argument according to Dembski. In Section 6 I encapsulate objections to Dembski. I conclude the chapter (with Section 7) by claiming that Dembski forwards a coherent model of design inferences that can be used in demonstrating that there is little difference between the way that Paley came to his conclusions two centuries ago and how modem philosophers of biology (such as I take Michael Behe to be, albeit that by profession he is a scientist) come to theirs when offering design explanations. Inference to the best explanation is demonstrated as lying at the crux of design arguments. In Chapter 3 I draw together the work of Michael Behe and Paley, showing through the mechanism of Dembski's work that they are closely related in many respects and that neither position is to be lightly dismissed. Section 1 introduces this. In Section 2 I introduce Behe's concept of irreducible complexity in the light of (functional) explanation. Section 3 is a detailed analysis of irreducible complexity. Section 4 raises and covers objections to Behe with the general theme being that (neo-) Darwinians beg the question against him. In Section 4 I apply the Dembskian mechanic directly to Behe's work. I argue that Behe does not quite meet the Dembskian criteria he needs to in order for his argument to stand as anything other than defeasible. However, in Section 5 I conclude by arguing that this is exactly what we are to expect from Behe's and similar theories, even within competing paradigms, in the philosophy of biology, given that inference to the best explanation is the logical lever therein at work. / KMBT_363 / Adobe Acrobat 9.54 Paper Capture Plug-in

A presente tese carrega o ônus de afirmar a relevância dos textos de Henry David Thoreau para a filosofia moral. Duas estratégias paralelas foram utilizadas para cumprir a tarefa. A primeira consiste na discussão pormenorizada de um conjunto de autores que apresentaram para Thoreau diferentes visões sobre a moralidade e o papel da filosofia na tecitura de uma vida digna de ser vivida: o Unitarismo de William Ellery Channing, as doutrinas do Scottish Common Sense de Dugald Stewart e Thomas Reid, o utilitarismo teológico de William Paley, o intuicionismo racional dos Platonistas de Cambridge (representados aqui por Ralph Cudworth), Orestes Brownson e Ralph Waldo Emerson – dois dos principais nomes do Transcendentalismo da Nova Inglaterra e Samuel Taylor Coleridge, Victor Cousin e Thomas Carlyle – primeiros intérpretes do Idealismo Alemão para o mundo de língua inglesa. A segunda estratégia articula a reação de Thoreau a essas diferentes posições sobre a moralidade, mostrando como, a partir dessa reação, ele foi capaz de formular um exercício de pensamento moral, cristalizado, emblematicamente, na escritura de Walden. O conceito de “identidade ficcional” foi pensado para capturar as diferentes técnicas utilizadas nesse exercício. / The present thesis carries the burden of asserting the relevance of Henry David Thoreau´s texts for moral philosophy. Two parallel strategies have been used to complete the task. The first is a thorough discussion of a group of authors who presented to Thoreau different views on morality and the role of philosophy in the weaving of a life worthy of being lived: William Ellery Channing´s Unitarianism, the doctrines of the Scottish Common Sense - Dugald Stewart and Thomas Reid, William Paley´s theological utilitarianism, rational intuitionism of Cambridge Platonists (represented here by Ralph Cudworth), Orestes Brownson and Ralph Waldo Emerson - two of the leading names of New England Transcendentalism and Samuel Taylor Coleridge, Victor Cousin and Thomas Carlyle - first interpreters of German Idealism to the English-speaking world. The second strategy articulates Thoreau´s reaction to these different positions on morality, showing how, from this reaction, he was able to formulate an exercise in moral thinking, crystallized, emblematically, in the writing of Walden. The concept of "fictional identity" was designed to capture different techniques used in this exercise.
