Return to Philosophy Proseminar

9/1

This was our introductory class. We made introductions, went over the course goals, the course website, and wiki. We brought up a wide range of topics for use in class.

9/22

Dennett's general argument in Ch. 2:

IC/P. Darwin's theory of natural selection establishes a process by which variation and species can be explained as a result of incremental change.

IC/P. The features of the process of natural selection are also the features of algorithms (substrate neutrality, mindlessness, guaranteed results).

C. Natural selection may an instance of a broader algorithmic process which explains the emergence of order in natural systems.

Dennett's general argument in Ch. 3:

The following claims are argued for, but also occur as premises in the larger argument of the book.

IC/P. Darwin's algorithm allows for explanations of order without reference to telos.

IC/P. Explanations of order without reference to telos undermine traditional views of the role of mind in order.

IC/P. The algorithm of selection can be thought of as operating within a "design space." A good trick, such as "reinforcement learning" may give an organism a way of creating order in its phenotype, not just accumulating design in its genotype.

IC/P. Using the algorithm of selection in this way involves an acceptable reduction.

Some notes on readings:

Foucault:

124: "Foucault is often classified as a cultural historian, but he preferred the designation "archaeologist of knowledge."

127: "Of the universals that reason claims to know, none is more crucial in the modern era than what we call "human nature." In his analysis of this concept, Foucault avoids such abstract questions as "What is human nature?" and "Does human nature exist?" Instead he asks, "How has the concept of human nature functioned in our society?" Framing the question in this manner opens the way for his program of undermining the Enlightenment self. "

128: "All of this is to say that Foucault moves us beyond structuralism to "post-structuralism." He moves us over the boundary between modernism from postmodernism (although he himself does not use the term).25 Postmoderns like Foucault no longer engage in a quest for an independent self, a given reaUty governed by lawlike regvdarities. They tend to be engaged in something more like interpreting texts. And in this endeavor, they assume not that every text has a single unifying Structure but, to the contrary, that texts are almost infinitely complex. In short, the postmodern paradigm, as exemplified by Foucault, celebrates complexity?-^ "

132: "Knowledge inescapably linked to power."

Derrida:

139: "He was coming to what seemed to him the inescapable conclusion that philosophy is a literary genre. "

140: "In a sense, Derrida begins where Kant leaves off. He raises the question "What foundation can we offer for our use of reason?"2 But he questions the modern trust in reason chiefly by undertaking a ruthless exploration of the nature of language and its relation to the world. In this enterprise, Derrida offers a critique of the so-called "realist" understanding of language — the view that our statements are representations of the world as it actually is apart" from human activity. Derrida denies that language has a fixed meaning connected to a fixed ality or that it unveils definitive truth. He wants to divest us of thi modern concept and open us up to the "hermeneutical" possibilities of the written word, the possibilities that arise as we engage in an ongoing conversation with texts.7"

142: [Important to appreciate Husserl's position: "Husserl renews the perennial modern attempt to provide an indisputable foundation for reason and language. Reminiscent of Descartes, he sets out to discover the primordial structures of thought and perception. He is convinced that this is facilitated by elevating knowledge that arises from authentic "self-presence" above knowledge based on memory, anticipation, or traces of an absent experience. This differentiation, in turn, requires a demarcation between the "now," where the subject is located, and the receding horizons of past and future. "

144: "Derrida concludes that in the end language is merely "selfreferential. ... But how do we account for our experience of existing as a self in the "now"? Derrida suggests that the experience of a singular, objective present" is an illusion. What we experience in the present is actually the result of a complex web of meanings that is constantly changing. Through language and concepts, we impose the sense of objective meaning on the flux of experience."

148: "Derrida's primary goal is to divest us of logocentrism by showing the impossibility of dravmig a clear line between reality and our linguistic representations. His chief focus, of course, is written language texts. He wants to wean us from too quickly assuming that we can discover the meaning inherent in a text, and he does this by demonstrating the difficulties of any theory that defines meaning in a univocal way, whether by appeal to what the author intends, what literary conventions determine, or even what a reader experiences. 102 Afi 102 After aU our theorizing, there still remains "the free play of meaning," which is the result of what Derrida calls "the play of the world." The text always provides further connections, correlations, and contexts and hence always has the potential to yield further meanings. "

Rorty:

151: "The<Pragmatist Outlook At the heart of the pragmatist tradition pragmatism is the abandonment nf-x iA^^ 4-u^+ v,ac reianed in philosophy pragmatism is the abandonment of a idea that has reigned in philosophy since the Enlightenment — namely, that the mind is the "mirror of nature."

152: "The pragmatist view of truth is nonrealist rather than realist. ist. The alist works from the assumption that we have direct access to the world independent of language and that our language follows from our observations of this objective, given worid.... The nonrealist, in contrast, begins with the assumption that our iccess to the world is mediated by language. "

153 "Because it is nonrealist, nonessentialist, and nonrepresentationalist, the pragmatist view of truth elevates coherence rather than correspondence. The modem epistemological project is grounded m the correspondence theory of truth. Rorty characterizes the goal of this theory as penetrating the veil of appearances in order to glimpse things as they are in themselves. Measured by the correspondence criterion, statements always have a clear truth value: they are either true or false. And we can discover the veracity of an assertion by checking whether or not it corresponds to the reality it purports to describe. ... Rorty credits Dewey for pointing us in a morrhelpful direction. In place of the assumption that beliefs represent reality, Dewey substitutes the idea that beliefs are tools for dealing with reality; they are maxims that dictate the behavior of the one that holds them."

156 "First, Rorty joins the postmodern assault on the modern concept of the self. He rejects Descartes's view of the self as an autonomous thinking substance, characterizing it instead as a centerless and everchanging web of beliefs and desires that produces action. 134

157: "But rather than bemoaning the loss of a transcendental vantage point, Rorty welcomes the new situation. It is beneficial, he says, because it builds our sense of community."

Range of positions on faith and reason

1. Faith is no less rational and susceptible to demonstration than science.

2. Faith and Science have distinct forms of rationality, language games, validity criteria, etc. (persons/bodies)

3. Faith involves commitments of individuals to communities on the basis of shared experience and belief. Faith doesn't just involve a distinct kind of rationality, but it focuses on distinct objects of knowledge, such as our relationship to totality. Scientific investigation asks fundamentally different questions in fundamentally different ways.

4. Faith is experiential; reason is theoretical. Reason comes late to faith. (evidence from sociology of religion on conversion, history of christianity).

Quotes from Fides et Ratio

"Faith and reason are like two wings on which the human spirit rises to the contemplation of truth"

establishes the authority of reason through philosophy but indicates that a reason for talking about faith and reason is that modernity has abandoned the search for transcent truth, focusing instead on human subjectivity.

"For the inspired writer, as we see, the desire for knowledge is characteristic of all people. Intelligence enables everyone, believer and non-believer, to reach "the deep waters" of knowledge (cf. Prov 20:5). It is true that ancient Israel did not come to knowledge of the worid and its phenomena by way of abstraction, as did the Greek philosopher or the Egyptian sage. Still less did the good Israelite understand knowledge in the way of the modem world which tends more to distinguish different kinds of knowing. Nonetheless, the biblical world has made its own distinctive contribution to the theory of knowledge. "

pars 37-39 -- good discussion of Catholic adoption of philosophy and wariness about it.

43: "More radically, Thomas recognized that nature, philosophy's proper concern, could contribute to the understanding of divine Revelation. Faith therefore has no fear of reason, but seeks it out and has trust in it."

46: "5t. It is not too much to claim that the development of a good part of modem philosophy has seen it move further and further away from Christian Revelation, to the point of setting itself quite explicitly in opposition. This process reached its apogee in the last century."

48: "48. This rapid survey of the history of philosophy, then, reveals a growing separation between faith and philosophical reason.

Calls for a recovery of the unity of faith and reason. Claims Modern Philosophy has made "wrong turns".

54 "Later, in his Encyclical Letter Humani Generis, Pope Pius XII warned against mistaken interpretations linked to evolutionism, existentialism and historicism. He made it clear that these theories had not been proposed and developed by theologians, but had their origins outside the sheepfold of Christ".^ He added, however, that errors of this kind should not simply be rejected but should be examined critically: "Catholic theologians and philosophers, whose grave duty it is to defend natural and supernatural tmth and instill it in human hearts. cannot afford to ignore these more or less erroneous opinions. Rather they must come to understand these theories well, not only because diseases are properly treated only if rightly diagnosed and because even in these false theories some tmth is found at times, but because in the end these theories provoke a more discriminating discussion and evaluation of philosophical and theological tmths".^ "

74ff "75. As appears from this brief sketch of the history of the relationship between faith and philosophy, one can distinguish different stances of philosophy with regard to Christian faith. first, there is a philosophy completely independent of the Gospel's Revelation: t\ ...76. A second stance adopted by philosophy is often designated as Christian philosophy. The term seeks rather to indicate a Christian way of philosophizing, a philosophical speculation conceived in dynamic union with faith."

82: "A radically phenomenalist or relativist philosophy would be ill-adapted to help in the deeper exploration of the riches found in the word of God."

seems to expect philosophy to be metaphysical. "If I insist so strongly on the metaphysical element, it is because I am convinced that it is the path to be taken in order to move beyond the crisis pervading large sectors of philosophy at the moment, and thus to correct certain mistaken modes of behaviour now widespread in our society. " [Arguably, using this commitment to a prior conclusion about philosophy could involve some circularity in the argument.]

dangers: eclecticism (87), scientism (88) -- not a great characterization, pragmatism (89), postmodernism (91)

Michael Tkacz on Gould and the Catholic Tradition

Gold's NOMA hypothesis [1] recognizes that moral and religious values might be established by different kinds of authority and argument than strictly scientific questions.

Tkacz tries to equate Gould with Fideism. In one sense this is a reasonable comparison. If rationality is one thing and fideist believe in a sharp separation of faith and reason, then it makes sense that fideists would regard faith as non-rational (or irrational). But that is not Gould's position. I think he would deny that NOMA implies the nonrationality or subjectivity of non-scientific questions. In any case, one could argue that faith and reason operate differently within a normal rational individual without committing yourself to the existence of the object of faith beliefs. That's a variant of NOMA, but it should show you some of the theoretical room you have here.

Thesis: "At the same time, the order of learning shows that theology is as much a science as are the sciences of physical being; that is, the religious beliefs which theology investigates and articulates as knowledge are no less rational and objective than are the beliefs about the physical world investigated and established in the natural sciences. This is because the same intellectual capacity which allows for human knowledge of the objects of the natural sciences is also that by which human beings know the object of theology."

Barrett, Cognitive Science of Religion

1:"Rather than specify what religion is and try to explain it in whole, scholars in this field have generally chosen to approach 'religion' in an incremental, piecemeal fashion, identifying human thought or behavioral patterns that might count as 'religious' and then trying to explain why those patterns are cross-culturally recurrent."

2:CSR "seeks to detail the basic cognitive structure of thought and action that might be deemed religious and invites historians, anthropologists, sociologists, psychologists and other religion scholars to fiU in the hows and whys of particular religious phenomena."

":...through the course of development in any cultural context, human mind/brains exhibit a number of functional regularities regarding how they process information. These functional regularities are also known as domain-specific inference systems or 'mental tools'.^ Foi For instance, one mental tool concerns language. Humans (especially pre-pubescent humans) readily acquire and use natural languages but are not facile with non-natural symbolic communication systems such as binary code."

TC - Theological Correctness -- studies involving online/offline tasks

MCI - Minimally Counterintuitive Ideas -- 4 " Compare the idea of a barking dog that is brown on the other side of the fence to a barking dog that is able to pass through solid objects on the other side of the fence. The first dog is wholly intuitive and excites litde interest. The second dog is slightly or minimally counterintuitive and is, consequently, more attention demanding but without overloading on-line conceptual systems. The idea of a dog that passes through soUd objects is made of metal parts, gives birth to chickens, experiences time backwards, can read minds, and vanishes whenever you look at it would amount to a massively counterintuitive concept - if it is a coherent concept at all."

-transmission advantages for MCI's?

Older research -- Guthrie "Faces in the Clouds" - evolution would favor false positives in "agency detection". This may explain hyperactive agency detection. HADD

6: "Additional motivation to talk about and believe in gods may come firom their ability to account for striking events that otherwise have no intuitive explanation."

1. Why is Hobbes credited with anticipating the kind of thinking in game theory?

2. What is the distinction between parametric and non-parametric considerations?

3. What is utility in game theory? Why do ordinal rankings matter more than absolute preferences?

4. What is the Prisoner's Dilemma? What does it show?

5. What is a Nash equilibrium?

6. What are some characteristics and strategies of repeated games?

7. How is game theory applied to evolutionary contexts?
