Science/Philosophy discussion on PF

Looks to be a very fascinating discussion about science and philosophy shaping up on the Philosophy Forums. At least, fascinating for my tastes, since I'm perennially interested in the question of what use philosophy really is these days compared to science.


Anyway, the thread starts out by directing several questions to John Searle (who is actually a member of the forums, although I suspect far too busy to be very active). Searle himself did give one response, but since then the thread's been drawing other participants; nonetheless, so far it has been a high caliber and well-reasoned discussion, by my estimation.

Here's a sample to whet your appetite, from the original poster (HamishMacSporran)'s response to Searle's own response:
... [M]any scientists take the view that the scientific revolution was made possible not by an accumulation of philosophical analysis, but instead by a rejection of the existing philosophical systems in favour of a new experimental method. From this point of view, scientists don't need philsophers [sic] to do their groundwork for them, but should instead ignore their clever arguments and focus on doing experiments. Hence the motto of the Royal Society, "Take nobody's word for it".
...

You [Searle] also raise the issue of computationalism within cognitive science, and your arguments against it. Whatever their merits, these arguments have not led to a conclusive rejection of computationalism. Dennett, for example, continues to deny your conclusions are valid, and the mind as a computer program metaphor continues to be common currency among cognitive scientists.

To many scientists this is just another symptom of philosophy's malaise: nothing ever gets resolved. That's why, instead of arguing for another thousand years about whether universals exist, they believe they need to focus on questions that can be definitively answered by experiment, with some even claiming that questions outside this domain are meaningless.

Does the computationalist hypothesis really have any experimental implications for cognitive scientists? What effects would you expect your arguments to have on a cognitive scientists research program? Are there benefits of philosophical dispute even in the case that no definite conclusion is reached?

Well-known philosophers who did not start out with philosophy

A while ago I noticed that quite a number of recent-ish philosophers did not actually receive B.A.s in philosophy--or whatever their equivalent undergraduate study was. So, I scoured Wikipedia (and the related internet) to compile a list of all the eminent philosophers who fit this criteria. The number is surprisingly high--or, perhaps I should say, the number of very influential philosophers on this list is quite high. I am certain that there are many, many more philosophers in general who did take philosophy as their first college degree, but if we only count only those philosophers with a very dramatic influence, I think we would find comparable numbers between those who began with philosophy and those who began with something else.

This list is unfortunately quite biased in favor of analytic philosophy, since that is the area I am most familiar with, although I did try to include some philosophers from other fields. I looked for philosophers from the end of the 19th century on--Nietzsche may be stretching it a little, but oh well. I also included a few notes about later/higher education, when it deviated from philosophy.

All sources are from Wikipedia unless noted otherwise. The list is in no particular order, although I did clump some names together based loosely on association or contemporaneity.

What was their focus as an undergrad?
---

Friedrich Nietzsche: philology (he later received a doctorate in this same subject)
Gottlob Frege: mathematics and physics
Bertrand Russell: mathematics (although he did study philosophy as an undergrad too)
Alfred North Whitehead: mathematics (also taught as a professor of mathematics for some time, before eventually becoming a professor in philosophy)
Ludwig Wittgenstein: mechanical engineering (until he came across Frege and Russell)
Karl Jaspers: medicine (received an M.D. and studied psychology. Did not study philosophy until he was 40)
Edmund Husserl: mathematics (followed by a PhD in the same subject)
Karl Popper: medicine? (I can't find anything that talks about his undergrad education, but he he received a PhD in Psychology, and this was early enough that he probably went to med school)
William James: another M.D. (Also did not study philosophy until he was older)
Thomas Kuhn: physics
Rudolph Carnap: physics (although he also studied logic and Kant's Critique). He originally intended to write a physics thesis--but both the philosophy and physics departments reputedly rejected his it as being too much like the other subject. He eventually wrote a more philosophically oriented thesis, so he ended up with a degree in philosophy.
Charles Sanders Peirce: chemistry (followed by an M.A. in chemistry too; source: SEP). In all fairness, it seems he also studied philosophy on his own time, and the reason he continued with chemistry was largely to support himself while he pursued logic.
Keith Donnellan: math education (source: biography on his site)
Max Black: mathematics. (I think, anyway. The only source I could find is a little unclear about it--and it does say that he talked much with many other budding philosophers of mathematics; source)
Saul Kripke: mathematics
David Chalmers: mathematics and computer science (afterwards studied for his PhD under Douglas Hofstadter (who is something of a computer scientist or cognitive psychologist--not a philosopher per se, but he is a very philosophically-minded polymath))
Otto Neurath: mathematics
Nancy Cartwright: B.Sc. in mathematics (source: cv from her site)
R.M. Hare: Classics (source)
Martha Nussbaum: theater and Classics
Jean Baudrillard: German (and later received a doctoral degree in sociology)
Arthur Danto: art and history
Hartry Field: mathematics (source)
---

Very interesting, is it not? What I find particularly fascinating is that there seem to be many more "crossovers" from non-philosophical fields among those philosophers who wrote on metaphysics or the philosophies of science, mind, logic, or math--rather than, say, philosophers who are known principally for their work in ethics. And that's not all. Observe the following list of double (and more) undergrad majors:

W.V.O. Quine: mathematics and philosophy
Frank Jackson: mathematics and philosophy
Hilary Putnam: mathematics and philosophy
Jaegwon Kim: French, mathematics, and philosophy
Ernst Mach: philosophy, mathematics, and physics (followed by a doctorate in physics).
Imre Lakatos: philosophy, mathematics, and physics
Carl Hempel: philosophy, mathematics, physics (source: IEP)
Paul Churchland: philosophy, mathematics, and physics (Source: c.v. from his website)
Philip Kitcher: mathematics and history & philosophy of science (source: c.v. from his website)
Nick Bostrom: philosophy, mathematics, mathematical logic, and artificial intelligence (source: cv from website)

Timothy Williamson: Philosophy and mathematics.

Notice any, ah, glaringly obvious trends there? So, if you're an analytic philosopher interested in something beyond ethics--why aren't you brushing up your math skills right now? Some physics surely couldn't hurt either.

(I should note that a few other relatively frequent double majors showed up--such as law, economics, political science, and the Classics--but these were largely dwarfed by the majors in mathematics. This may be due to my afore-mentioned analytical philosophy bias, but I find it very noteworthy nonetheless.)

The Aftermath of Absurdity: H?

The title of this post ("The Aftermath of Absurdity: H?") contains an oblique reference to the futurist philosophy known as transhumanism. Transhumanism, as the Wiki link shows at the time of this writing, is occasionally represented/symbolized by the characters >H or H+ to indicate progressing beyond humanity in its current form (which is presumably symbolized by H). I will use H?, then, to indicate a curiosity or uncertainty about what exactly a human is in the first place, before we go about augmenting it.

What does it mean to be human?

It means to be a finite being {limited to subjectivity; prey to irrational impulses; hampered by the physical world} with aspirations toward divinity {sub species aeternitatis; pure rationality; transcending physicality}. Even those of an atheistic persuasion frequently seek this divinity in one way or another--and, in fact, the atheist strives to see through God's eyes much more often than the theist, since the theist normally considers the very thought blasphemous {Lucifer went astray when he desired God's position; humanity was punished when it built a tower meaning to ascend to the heavens; and, of course, original sin is the very product of seeing through God's eyes--the serpent tells Eve that knowledge of Good and Evil will make her godlike, and this is indeed what condemns humanity}. When the scientist desires to understand the operations of the universe beyond our immediate ability to perceive {knowledge of particles; the constituents of stars; DNA; functioning of the body}, when she desires a simple system of laws from which everything else may be derived {Grand Unified Theory}, she is desiring to transcend her senses (and all that which is given immediately and simply) to discover the true nature of reality--something which, presumably, only a god would have direct access to. What was the pre-human world like? How was it formed? What "makes" a plant grow? Does the universe exhibit counterfactual definiteness? If not, is Laplace's demon an impossibility? Would a god be subject to Heisenberg's uncertainty principle, or to the observer effect?

The aspiration to know this, coupled with the apparent impossibility of truly knowing, is one of the things that makes the human absurd. So many humans for so long have wanted to know what goes on "behind the scenes," and wanted to transcend this paltry, unreliable chunk of biological flesh and bones. Science/technology is presumably our best bet to facilitate this transcendence: it allows us to cleverly sneak around the limitations placed upon us by Nature, augmenting our vision through microscopy and telescopy, detecting and analyzing electromagnetic waves beyond our senses' ability to register, measuring quantities which we could never observe unaided. And, with the deepening of our knowledge, the greater becomes our ability to construct devices which manipulate nature for our own ends. This is the transhumanist goal, and, to a lesser extreme, the intention of nearly every technological endeavor since the dawn of time: harness natural forces so that we may prolong our life, ease our suffering, enable our own enjoyment.

Ever since we first realized that we could more regularly and readily find food if we planted seeds in the right kind of earth, that we can use sticks and rocks and other things to help us hunt and defend ourselves, that we can warm ourselves with animal skins and leaves, we have been on this path. The path which will make us God, perhaps? The path toward perfection?

Perhaps not. Perhaps I again assume too much about the rest of humanity, and I ascribe lofty, grandiose ambitions where they may not be entertained. Perhaps most people want simple, material/social comforts; they are not concerned with knowledge, or even with "transcending" the physical body through virtual reality and cybernetic augmentation. But I think they must be, otherwise why would the promise of heaven be so enticing? Why else would television and computer/console games enjoy the intense, sometimes addicting popularity that they have?

But then, perhaps it is only philosophers who dream this way.

What does it mean to be a philosopher ("What does 'P?' mean")?

Among other things, the philosopher examines presuppositions which underly our most fundamental beliefs. She makes the implicit explicit. She wanders the borders of human thought, heroically grappling with those speculative concepts which are on the outer limits of our ability to reason about, attempting to "make sense" of it all. ("Make sense" is an appropriate way to describe the process: humans often rely on metaphors derived from our senses when attempting to apprehend an abstract concept. See Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being by George Lakoff and Raphael E. Núñez for some fascinating examples of how humans tend to map abstract mathematical concepts onto familiar experiential concepts.)

Now, the curious thing about philosophizing is its notorious "arm-chair" method of inquiry. In contrast with the empirical sciences, philosophy presumes to discover knowledge in a peculiar manner: reasoning built off of common intuitions, supplemented and refined by 1) the arguments of other philosophers, both those from the past and those contemporaneous; and 2) the discoveries handed down from the sciences. Rather than going out into the world and poking about, setting up controlled environments and acquiring measurements to discover regularities, the philosopher sits atop a mountain of academia, arguing vociferously about the ultimate truths of possibility and necessity. Truths applicable, presumably, to all modes of knowledge and all realms of inquiry--that is to say, truths applicable universally.

Early science - natural philosophy

This has not always been the case: during the Modern Era, "natural philosophy" gained prominence with its new-fangled focus on experimentation. A number of noteworthy philosophers either contributed directly to what we now call science or influenced it strongly with their theories, such as Descartes, Kant, Sir Francis Bacon, and Leibniz. Isaac Newton's legendary tome that lay the groundwork for classical physics was titled Philosophiae Naturalis Principia Mathematica, or "mathematical principles of natural philosophy." Newton and the other members of the Royal Society certainly considered their work to be "natural philosophy," and the continued use of "Philosophical Transactions of the Royal Society" as a name for the longest running science journal in existence is a testament to that attitude. This was by no means exclusive to the Modern period: Aristotle may have been one of the world's first biologists, for all that his conclusions were rife with what we now know are accuracies. Copernicus and Galileo no doubt considered themselves philosophers, etc. etc.

However, with the rise of natural philosophy and its subsequent successes came a devaluation of regular philosophy. By the 19th century (or perhaps the early 20th at the latest), "natural philosophy" had separated even farther from traditional philosophy; it was hereafter known as "science." Strong borders began to appear between the two, spurred on by the anti-metaphysical, pro-empirical agenda of the logical positivists. Since then, science, along with every other field in academia, has undergone a radical process of specialization: we have the natural sciences of physics, chemistry, and biology, then the social sciences of psychology and sociology (and perhaps economics and political science, depending on where ones draws the line). Finally, we have mathematics and computer science, which are hardly empirical, yet they are of such a systematic nature and of such relevance to science proper that they often fall under the general category "science." This segregation of subject matter seems to have arisen as a method of shared labor, or divide-and-conquer strategy: as scientific knowledge accumulates, it becomes inefficient--perhaps impossible--for one person to stay abreast of the current research, and impossible furthermore to devote one's own time to experimentation and theorizing toward the many facets of science at once. Specialization in academia, not surprisingly, mirrored the socio-economic specialization that sprung forth during the Industrial Revolution in the form of division of labor, mechanization, and streamlined factory assembly. Not that it was a new concept: Plato's Republic, Hume's Treatise, and Adam Smith's Wealth of Nations (and no doubt other sources) advocated specialization as the key to efficiency; and, indeed, natural selection itself preceded every thinker through the specialization of cells within an organism and the specialization of individuals within a pack or colony. However, the exponential, near-simultaneous growth of technology, population, science, and the humanities in the last two hundred years exquisitely highlights the role specialization has played, and it is doubtful we would have made the progress we have without it.

Specialization, in conjunction with cooperation, is a wonderful thing which enables synergy--a mysterious emergent property resulting from the pooling and interaction of individual components. Unfortunately, specialization has its drawbacks too: namely, the walls which develop between the expert and the non-expert. Mathematics is a perfect example; from what I hear, mathematics is perhaps the most inaccessible field even to expert mathematicians: at the highest levels of specialization, there might be some ten or fifteen people in the world capable of fully understanding what a given paper tries to prove. A mathematician who studies one niche branch of mathematics may be completely lost when faced with another.

So what does this have to do with philosophy? Well, philosophy was the mother of all inquiry--rational speculation began here, but academic subjects splintered off into child fields that have since then gained their own prominence. In the case of the sciences, that prominence now dwarfs philosophy such that philosophy is the "handmaiden of science," at best, and useless dialectical gobbledygook at worst. And, the inaccessibility that is a byproduct of specialization exacerbates the divide by making it difficult for science to communicate with non-scientific disciplines (see C.P. Snow's Two Cultures for a notorious take on the gulf between the science culture and non-science culture).

So, I suppose I am interested in what relevance philosophy has to non-moral matters. Is there any point to philosophers talking about science and mathematics when many scientists and mathematicians pretty much ignore us? If we have ascertained that philosophy does not give results the way that science has, what role does it play for us? I am interested in science and mathematics, but I do not have the training nor time required to get a full grasp on what the experts are doing. Should this concern me? Is there anything that can be done about it?

Is there a way to be a better/improved/augmented philosopher ('P+'), and what is the relationship between 'P?' and 'H?'?
