Hobbes and modern science v. Descartes (v. Rorty)

Oct 20th, 2008 Posted in philosophy | No Comments »

When I first read the opening from Hobbes’ Leviathan as an undergraduate, I laughed.  I laughed heartily.   There was something clearly, and quaintly, absurd about his simple (though perhaps vaguely Rube-Goldberg-esque) chain of mechanistic causal events which for him became the workings of the universe.  From Hobbes, Leviathan, Chapter 1: Of Sense:

The cause of Sense, is the Externall Body, or Object, which
presseth the organ proper to each Sense, either immediatly,
as in the Tast and Touch; or mediately, as in Seeing, Hearing,
and Smelling: which pressure, by the mediation of Nerves, and other
strings, and membranes of the body, continued inwards to the Brain,
and Heart, causeth there a resistance, or counter-pressure,
or endeavour of the heart, to deliver it self: which endeavour
because Outward, seemeth to be some matter without.  And this Seeming,
or Fancy, is that which men call sense; and consisteth, as to the Eye,
in a Light, or Colour Figured; To the Eare, in a Sound; To the Nostrill,
in an Odour; To the Tongue and Palat, in a Savour; and to the rest
of the body, in Heat, Cold, Hardnesse, Softnesse, and such other qualities,
as we discern by Feeling.  All which qualities called Sensible,
are in the object that causeth them, but so many several motions
of the matter, by which it presseth our organs diversly.  Neither in
us that are pressed, are they anything els, but divers motions;
(for motion, produceth nothing but motion.)  But their apparence to
us is Fancy, the same waking, that dreaming.  And as pressing, rubbing,
or striking the Eye, makes us fancy a light; and pressing the Eare,
produceth a dinne; so do the bodies also we see, or hear, produce
the same by their strong, though unobserved action

The absurdity, to me, was not merely that Hobbes thought that he had figured out the mechanisms that ruled over our senses and feelings simply by expanding simple principles of interaction of bodies.  Rather, I laughed because I thought it was preposterous that Hobbes thought to account for non-physical things, like emotions and mental activity, by means of materialist mumbo-jumbo.

Curiously, I was simultaneously quite sincerely open to, if not entirely credulous of, the findings of modern psychological studies which played the exact same role–namely, making the naturalist presumption that those things which seem incorporeal (like thoughts, sensory data, and emotions) could be studied as causes of simple physical interactions observable, for instance, by means tools like nMRI.  Modern naturalist science (I’m convinced that naturalism is not in any way definitional of science, but rather a mere ubiquitous presumption of modern scientists and the in-vogue scientific paradigms) simply has a more complex version of Hobbes’ materialism.  Rather than simply positing that something “preseth on the eye”, biologists a conception of our senses as the products of a complex of chemical and physical interactions which can all be reduced, theoretically, to a naturalistic incarnation of particle physics.

Each of these two perspectives–Hobbesian materialism and modern naturalist science–has issues with the classical Cartesian mind/body dualism.  What I considered incredible in the Hobbesian perspective, I should recall, is not the given dualism ” between two sorts of ‘stuff’, material and immaterial” (as Rorty calls it), but was once an idea marked more by its novelty than its broad acceptance.  With what reasons did dualism replace materialism as the dominant metaphysical structural assumption?  Certainly a number of enticing dualist metaphysical systems exist, and we might have good reason/s–logical or practical–to accept any of these.  I am not convinced that this dualism is essentially reasonable (or for that matter, if it is, that it is reasonable that we should assume that the non-material side of this dualism should have laws similar to our empirically-derived laws for the natural world); I am likewise not convinced that the material dualism has any cogent appeal over metaphysical tri-ism, quad-ism, or infinit-isms (do metaphysicians have terms for these?), other than theoretical parsimony.

Rorty speaketh

Richard Rorty opens Philosophy and the Mirror of Nature, Chapter 1 with this to say about dualism:

Discussions in the philosophy of mind usually start off by assuming that everybody has always known how to divide the world into the mental and the physical–that this distinction is common-sensical and intuitive, even if that between two sorts of “stuff”, material and immaterial, is  philosophical and baffling”

While I don’t think that this position is completely fair or accurate, Rorty’s point is well-made.  If we need a dozen or more metaphysical systems for bridging that “between” in the mind/body dualism–epiphenominalism, parallelism, occasionalism, and their ilk–and the whole dualist project is so difficult for us to fine-tune, what makes this dualism seem so obvious?  I suspect Rorty is not just being eristic when he implies that its our dogmatic entrenchment which makes this dualism seem natural, not some objectively-apparent metaphysical substructure.  This dogmatic entrenchment, I think, is what made Hobbes’ materialist metaphysics seem so quaint and rediculous; meanwhile, my dogmatic entrenchment in the authority of modern scientific findings allowed me to provisionally accept a sort of materialist perspective.  Perhaps it is unfair of me to so readily accept one while simultaneously poo-poo-ing the other.

I enjoy Rorty’s criticism of this dualism, but I think my position is still largely gauche to his.  We should not ignore the predominant metaphysical assumption of dualism–nor, conversely, the metaphysical (or physical) presumption of monism/materialism (or other metaphysical -isms).  We simply ought to be aware of, but not necessarily strictly opposed to, our dogmatic assumptions.  Likewise, we should take note when our various presumptions do not jibe well.  Do we assume dualism, yet affirm the findings of research that presumes or requires monism?  If so, is it merely the result of the brute cultural force of one over the other, or are there good reasons for believing both?  Certainly we might simply mean “monism” and “dualism” in different ways.  Dualisms, of course, may be distinctions between “subtances”, “properties”, or “predicates”, among other things; or perhaps it is fair of us to utilize dualist assumptions in a monist reality or monist assumptions in a dualist reality, if they get us the practical results we desire in some parsimonious way in some areas.  In the same way that we still utilize Newton’s laws for some gravity calculations, despite the existence of more precise post-Einstein calculations, it may simply be the best to use one or the other as a tool.  By this point you surely have figured out that this is my pragmatic proposition for an approach to metaphysics; It is my belief that a “dualism assumption awareness” campaign is much more likely to give us the results we desire than a “dualist-smashing” campaign which it seems to me Rorty is using to get us to agree to presume materialism for pragmatic purposes (corrections/comments greatly appreciated!).

Philosophy and the Mirror of Nature: Introduction

Oct 15th, 2008 Posted in philosophy | No Comments »

Having now crossed the introductory threshold into Rorty’s work, a few general notions have struck me.  The first is that it seems to me that Rorty, despite having a varied set of philosophical positions as a youth (assuming his autobiography is correct) and during his early philosophical career, held a remarkably stable philosophical position from the writing of Philosophy and the Mirror of Nature through the end of his life.  Waggish thinks that you can sort Rorty’s positions into three categories: analytic, decontsructionist, and liberal populist (see Richard Rorty, 1931-2007).  So far, I disagree.  Yes, there are thematic differences in Rorty’s works.  It may also be true that pre-Philosophy and the Mirror of Nature-Rorty is a code-cracking (as Rorty calls himself) analytic philosopher with little to foreshadow his later anti-foundationalism aside from a caustic devil-may-care style of criticism.

However, Rorty’s topical differences, which even Waggish says exist simultaneously, hardly come off as differences in philosophical perspective.  If Rorty, who at this point in the work is wearing his goals and influences on his sleeve, is being honest about where this book is going and how it is getting there, the only foreseeable potential for change from 1979 to 2000 would be mere nuance.  Of course, this conclusion is both tentative and flippant, based on a few pages from a handful of varied books written decades apart.

Summary

To return to the content of the introduction itself, Rorty begins with a small gift–a brickbat for modern philosophy.  Philosophers since Kant, he claims, like to think of themselves as having access to the timeless problems and the timeless answers (or search for answers) that serve as the basis for all other human knowledge (and, I suspect he would be willing to agree, founds not only metaphysics/epistemology, but also ethics and now “meaning” as well).  We owe this foundationalism/arrogance, he states matter-of-factly, to John Locke’s ” ‘theory of knowledge’ based on an understanding of ‘mental processes’ ” as well as to Descartes’ conception of “the mind” as a distinct, process-like intangible.  From that point, the role of philosophy was developed into a “tribunal of pure reason, upholding or denying the claims of the rust of culture” with the assumption that philosophers had access to foundational mind/process upon which all of the rest of human knowledge is contingent.  Most of the grunt work here was done by Kant, but the job was not finished until neo-Kantians so embedded this foundationalism that ” ‘philosophy’ became, for the intellectuals, a substitute for religion.”

Many philosophers undermined this position.  Many, like William James and Nietzsche, were simply ignored or marginalized.  Eventually, though, criticisms became too great, and the works of Wittgenstein, Heidegger, and Dewey, for instance, have helped erode the authority and faith in philosophical foundationalism.  While many–notably Husserl and Russell–have attempted to re-foundationalize philosophy, Rorty seems to think that philosophy is ineluctably bound to be demoted from its position as high-meta-priest of knowledge and culture, certainly with his help.

Rorty promises to try to convince his readers not to think of philosophy as a means of obtaining objective truth (a mirror of nature); we ought to ditch our Greek/Cartesian dualisms, embrace a mildly Kuhnian historicism and a Deweyian conception of truth, and move on.

Discussion

So, are Rorty’s charges of philosophical foundational arrogance fair?  Anecdotally, I have found many of the philosophers whom I have met to be among the most humble, despite being among the most intelligent, of people with whom I have associated in general.  As a student of philosophy, I suspect that I’m prone to awarding philosophy that arrogant prize that Rorty wants to take away–the claim to holding, if not the answers that provide universal foundational knowledge, the meaningful questions that humans desire, or should desire, to ask.

If this is all that Rorty is getting at, his assessment seems somewhat fair.  I would add, however, that in modernity philosophy is not the only field which makes claims of this sort.  Religion, and theological studies, often make claims or seek objective meaning, objective ends, foundational understanding of truth, a method of prioritizing which places religion or religious belief or religious ethics or religious questions at the foundation of human existence.  Psychology, likewise, has claims to begin at the foundation of knowledge, the human mind itself.  Do not biology and biochemistry seek the same foundational understanding?  Don’t astronomers look for clues which they hope would give us foundational understanding of life and meaning?  Would not particle physicists claim that all these other pursuits are dependent upon their foundational knowledge?  Even in the humanities and social sciences–sociology, rhetoric, anthropology, history–it seems to me that some incarnation of claims to foundational access to knowledge, meaning, or importance are made.  Perhaps few or none of these claims have the same sort of epistemic or metaphysical bent to them, but I reckon that each is guilty of its claims to arrogance in its own way–perhaps moreso the product of the values of those entering these fields than by virtue of the unified claims of the field in general.

However, if perhaps only for historical and cultural reasons, the field of philosophy may be just a bit more chauvinistic than other areas of study.  Certainly after having been the apex of renaissance humanism’s educational hierarchy, after having been Boethius’s consolation, and having been the salient intellectual perspective enduring since the supposed Greco-Roman founding of Western Civilization, Philosophy may yet have a little humility due it.  Rorty thinks philosophers might need to quit calling their questions and answers eternal; we should recognize that philosophy as time and culture bound as the hard sciences.  Yale’s Anthony T. Kronman argues, in Education’s End (sold here), that philosophy and the rest of the so-called humanities are simply the last fields of study to be brought under the research ideal; perhaps an eventual full incorporation into this ideal (which neither I nor Kronman support) would give philosophy that historicist humility which has so far escaped so many philosophers still seeking to write that “last book”.

The “Cash Value” of my reading

I certainly think that Rorty’s criticisms are worth bearing in mind.  Perhaps I am guilty of being too-far embedded in the goals, practice, and culture of philosophy, but I think it is better that we meet Rorty only half way.  His historicist and antifoundationalist positions ought to be recognized and ought to strongly discourage us from believing in the permanence of any philosophical questions and/or answers.  However, I do not think that this means we should not still attempt or cannot ever achieve the kind of permanence or foundationalism that Rorty rails against.  While philosophy may seem old, I argue that is quite young.  Even if you claim that what we today call philosophy is the same animal that arose in Ancient Greece; or perhaps when Gilgamesh first contemplates his mortality; or perhaps the first time the first person “desired to know”, humans are a young species on a young planet with heck of a lot of learning yet to do.  Writing off foundationalism at this youthful stage of our development is, if nothing else, closing a giant door to inquiry.  Yes, Rorty, philosophers do not seem anywhere close to coming up with foundational answers, but leave us, please, our foundational questions and let us cavil a bit about them just in case.

Philosophy and the Mirror of Nature

In my attempt to learn a bit more from some “post”-analyitic philosophers, I’ve decided to begin by revisiting Richard Rorty’s Philosophy and the Mirror of Nature (sold here).  I rather regret going back to this text before having had direct experience with the work of Heidegger in particular, but I am also displeased that I have yet to read any substantial works from Wilfrid Sellars, David Donaldson, Rudolph Carnap and W.V.O. Quine.  However, I suspect that I will be aided by the fact that I have ventured at least gotten my feet wet in exploring John Dewey, Hans Gadamer, Richard J. Bernstein, Quine, and Wittgenstein since i first rushed through parts of Rorty’s work two years ago.

I have chosen to start with Rorty’s Philosophy and the Mirror of Nature for a number of reasons.  First, it seems to me something of a seminal work–for Rorty, for philosophy internally, and about philosophy from an external perspective.  Rorty’s criticisms are, if I remember well and if my sources are accurate, poignant, reflective, but not pleasing to the ears of most philosophers.  As such, he cannot be ignored.  Either Rorty’s harsh words are valid and philosophy must reform itself in some dramatic ways or philosophers must make a cogent rejoinder.  Since the writing of Rorty’s book, I suspect both have been done with countless subtle incarnations of each, and perhaps some not so subtle.

I have also selected this work for pragmatic reasons, because I think it represents a noteworthy pastiche of early Neopragmatist/postanalytic philosophers’ works (namely Quine, Sellars, and Davidson), as well as those of some of their influences (Wittgenstein, Heidegger, and to some extent Dewey).  Furthermore, there is a marked lack of analytic tradition philosopherss in my formal education in philosophy–a deficiency which I hope to allay at least to some degree by reading this work.  Finally, I have selected Rorty’s text over those of his peers because the philosophical exploration that I have just begun was encouraged by epistemological criticisms of Rorty’s later work–work which is foreshadowed very strongly in Philosophy and the Mirror of Nature.
