Here is the exchange between my friend who is interested in Duhem:
this comes from a recent article my "Duhem"
Google alert found for me:
Babette Babich, “Heidegger’s
Jews: Inclusion/Exclusion and Heidegger’s Anti-Semitism,” Journal
of the British Society for Phenomenology 47, no. 2 (April 2,
2016): 133–56, doi:10.1080/00071773.2016.1139927.
Babich, as fn. #62 says, is a student of Lonergan.
Here's where he discusses Duhem, ending with an interesting
observation. I haven't read Duhem's La science allemande
in its entirety; just the part I sent you regarding Einstein and
the "geometric/'mathematical' mind."
By contrast, especially for those of us up on our
Laruelle or our Stiegler or Meillassoux or our Simondon, and
even in conjunction with the present theme, thinking of
identities and differences, thinking of Heidegger and his Jews
in a French context, who reads Pierre Duhem, author of the
posthumous German Science?50
Have we today – even those of us interested, as I am interested,
in the history and philosophy and sociology of science – any
political geography of theory in science in connection to or
with hermeneutic reflection? In connection to Heidegger, ah,
yes, but not with respect to questioning science much less
technology? We leave to those in power their game plan, and we
do so without remainder. Critical theory has thus managed not to
be critical for years.
Where Duhem in 1916 criticizes the German turn of mind as it
finds expression in Gustav Kirchoff, a theorist of
mathematical physics, we could find Heidegger's words along
with Duhem's critique: “We can and will posit [poser] …
Wir können und wollen setzen … ”51
Note that this stipulative posing is by no means limited to a
dogmatic and axiomatic controversy. The mathematician David
Hilbert made this the watchword of the so-called Göttingen
programme, which project included Husserl.52
As Duhem continues to refute Heinrich Hertz's explicitly
deductive construction of mechanics,53
the problem is not that the postulate is arbitrary but rather
that it is, out of context and history, thereby articulated,
“imperiously”: “Sic volo, sic jubeo, sit pro ratione
voluntas. [I will it thus, I order it thus; let my will
stand in the place of reason.]”54
What Duhem ultimately sought, fierce as his gainsaying was,
was only the inclusion of specifically French science—this
would be the torch later taken up by Bachelard and Canguilhelm
and today, if less and less, Serres—finally admitted to the
table along with German science: “Scientia germanica
ancilla scientiae gallicae.”55
In the published version we can read Duhem citing Nietzsche's
contemporary and fellow philologist, Hermann Diels: “the
German is, here and now, on this earth, the sanctuary in which
the principle of order takes refuge.”56
Yet it is Duhem's extended citation of Wilhelm Ostwald that is
arguably the most disturbing, even using the language of a
“great secret” with respect to the German:
Germany wants to organize Europe
which, until now, has not been organized. I shall now
explain to you the great secret of Germany. We, or
perhaps rather the German race, have discovered the
factor of organization. Other people still live under
the regimes of individualism, when we are under that of
organization.57
When Duhem asks “[w]as Scholasticism not
essentially, as German science is, a work of the mathematical
mind”58
he can seem to approximate Heidegger's standpoint in his Beiträge
with respect to what Heidegger names Machenshaft,
where Heidegger writes in GA 95 (Überlegungen VIII, 5)
of the Black Notebooks currently under discussion.
“One of the most secret forms of the gigantic, and
perhaps the oldest, is the persistent skillfulness in
calculating, pushing, and intermingling through which the
worldlessness of Jewry is grounded.”59
Or else and still more troublingly, when Heidegger writes:
the temporary increase in the power
of Jewry has its ground in the fact that the metaphysics
of the West, especially in its modern development,
served as the point of attachment for the diffusion of
an otherwise empty rationality and calculative skill,
which in this way lodged itself in the “spirit” without
ever being able to grasp the concealed domains of
decision on its own. The more original and inceptive the
coming decisions and questions become, the more
inaccessible will they remain to this “race.”60
This last is only a prelude to the most
infamous of these quotes:
That in the age of machination,
race is elevated to the explicit and specially erected
“principle” of history (or just of historiology) is not
the arbitrary stipulation of “doctrinaires” but a consequence
of the power of machination, which must cast down
beings, in all their regions, into planned calculation.61
It can be argued that what Duhem calls “German science”
corresponds to what would come to be called “Jewish science”.62
52 I
discuss this with attention to the time that was the first few
decades of the twentieth century in the philosophy of science
(and mathematics) in Babich, “Early Continental Philosophy of
Science.
53 “Let us agree that this point – which
is itself nothing but an algebraic expression, only a world of
geometric consonance take to designate an ensemble of n
numbers – changes, from one instant to another, by an
algebraic formula. From this convention, so perfectly
algebraic in nature, so completely arbitrary in appearance, we
deduce, with perfect rigor, the consequences that calculation
can draw from it, and we say that we are setting forth
mechanics.” Duhem, “Some Reflections on German Science”, p. 93
54 Ibid.
55 Ibid., p. 112.
56 Duhem, “German Science and German
Virtues”, here p. 122.
57 Ibid.
58 Ibid., p. 123

5, GA 95, p. 97.
60 Heidegger, GA 96, pp. 46 (from Überlegungen
XII, 24).
61 Heidegger, Ibid., p. 38.
62 That argument can be made, but for his
part, Duhem is talking about “scholasticism”, that is what my
old Jesuit teacher, the Canadian Thomist, Bernard Lonergan,
author of the conspicuously named Method in Theology
(1972) and Insight: A Study of Human Understanding
(1957), with its famous listings of points to the seemingly nth
degree, no mere sic et non, took the mid-twentieth
century to an extraordinary pitch well beyond the tradition of
generalized empirical method of “transcendental Thomism”
inaugurated by the Belgian Jesuit philosopher, Joseph
Maréchal. Indeed, Maréchal was probably one of the reasons
Lonergan was able to answer my questions regarding the
intersection of mysticism and empiricism as well as he did.
Maréchal's initial main works included: Le point de départ
de la métaphysique: leçons sur le développement historique
et théorique du problème de la connaissance, 5 vols
(Bruges-Louvain, 1922–47) and Études sur le psychologie
des mystiques, 2 vols (1926, 1937).
German/Jewish
science (my attempt at a compact definition): a fabricated (magical) new
“physical” science derived from hypothetical equations—e.g. relativistic
dynamics and its geometric implications dictating the replacement of a planar
space with a gravitational field by a curved spacetime without gravitational field. The transition from the former to the
latter is essentially magical, thanks to the concoction of highly elegant algebraic
tools. It would therefore be worth investigating how the actual magic, in the
truly occult sense of the term, has impacted “Jewish science” and its use of
mathematics (as the intellectual Talmudic culture is riddled with magic
practices related to gematric ideas).
Also,
as I read a little bit of Duhem’s writings and get a sense of his Ampèrian affinities,
I’m wondering whether he was aware of (and, if so, what he thought of) the
tensor-based reformulation of electrodynamics (relativistically rewriting Maxwell’s
equations to account for the electromagnetic potential in terms of R4
using an electromagnetic field tensor and a current tensor). Electrodynamics
assuming GR has always bothered me a great deal because it essentially unifies Einsteinian
gravitation (its spacetime continuum) and electromagnetism by way of geometry,
not physics (as though the physics of E&M was ultimately dependent upon and
constrained by the non-physical relativistic dogma of gravitation).
Yes, that was fascinating. And the author quoted Duhem's German.
Duhem published in French, English, and German, and knew Latin and
Greek as well as reading comprehension in Italian! He was a true
polymath and polyglot.
"Ampèrian affinities":
Duhem certainly admired Ampère's experimental and theoretical
genius, but he disagreed with Ampère's Newtonian inductivism, which
held that "phénomènes électrodynamiques" are "uniquement
déduite de l’expérience," as Ampère subtitled his famous work.
Duhem discusses this in his Théorie
physique ch. 6,
- §4 (PDF p. 154): a critique of Newton himself ("Critique de
la méthode newtonienne. - Premier exemple : La Mécanique
céleste")
- §5 (PDF p. 158): a critique of Ampère ("Critique de la
méthode newtonienne (suite ). – Second exemple :
L’Électrodynamique").
(Duhem was very good at making everyone on all sides of a
debate very uncomfortable. ☺)
Duhem was familiar with Riemann's mathematics. We know this based on
a citation he made to a paper by the Italian mathematician Enrico
Betti. Duhem's 2nd doctoral dissertation (the accepted one)
was, after all, in the mathematics department; his 1st (the rejected
one) was in the physics department.
By "tensor-based reformulation of electrodynamics," are you
referring to Maxwell's quaternion way of writing things? For
example, in his Treatise on
Electricity & Magnetism (vol. 2), p. 232-233, where
he introduces the displacement current, he wrote the Maxwell-Ampère
Law
as
where
i.e.,
(true current) = (conduction current) + (displacement current);
is
the magnetic force;
is the
vector part of
(i.e., curl).
Regarding "occult" and "gematric [geometric?] ideas" in physics:
I like Steiner
(2009)'s term "Pythagorean analogies," i.e., "analogies
inexpressible in any other language but that of pure mathematics" (Karam
2014); he cites Maxwell's displacement current as the first
example of a "Pythagorean analogy" in physics.
Here are Duhem's views of quaternions and vector analysis (Théorie
physique ch. 4, §6 "L’École anglaise et la Physique
mathématique," PDF p. 62-63):
Mais chez les Anglais seuls l’amplitude d’esprit se
trouve d’une manière fréquente, habituelle, endémique ; aussi
est-ce seulement parmi les hommes de science anglais que les
Algèbres symboliques, le calcul des quaternions, la vector-analysis,
sont usuels ; la plupart des traités anglais se servent de ces
langages complexes et abrégés. Ces langages, les mathématiciens
français ou allemands ne les apprennent pas volontiers ; ils
n’arrivent jamais à les parler couramment ni surtout à penser
directement sous les formes qui les composent ; pour suivre un
calcul mené selon la méthode des quaternions ou de la vector-analysis,
il leur en faut faire la version en Algèbre classique. Un des
mathématiciens français qui avaient le plus profondément étudié
les diverses espèces de calculs symboliques, Paul Morin, me disait
un jour : « Je ne suis jamais sûr d’un résultat obtenu par la
méthode des quaternions avant de l’avoir retrouvé par notre
vieille Algèbre cartésienne. »
Also, you would be very interested in the
Notice
sur les Titres et Travaux scientifiques de Pierre Duhem
rédigée par lui-même lors de sa candidature à l'Académie des
sciences (mai 1913)
While Duhem wrote most of it—summarizing all his scientific,
philosophical, and historical researches—, Jordan wrote the
biography section, Hadamard wrote the section on the mathematical
aspects of Duhem's works, and Darbon (whom you may not have
heard of) wrote the section on Duhem's history of physics.
By the way, some considered Duhem "anti-Semitic" because of his
stance on the Dreyfus affair, yet he was close friends with the Jew
Hadamard, who held a very high opinion of Duhem.
Also, Duhem's influence has been vast, across many fields. For
example, the economist Schumpeter, in his preface to Fr. Dempsey,
S.J.'s erudite defense of the moderns' understanding of interest and
the medievals' arguments against usury, Interest
& Usury, mentions how Fr. Dempsey did for economics
what Duhem did for physics; they both showed the medievals'
contributions to their respective modern disciplines.
Thanks for this rich piece of Duhemian insights and many
references! Quite dense, owing to the vast extent (“across many fields”) of
Duhem’s multi-layer thought and writings.
Yes Maxwell’s equations can be reformulated using matrix
operators to represent quaternions. But, in field theories, quaternions are
broader algebraic tools than tensors and need not include any “relativistic”
alteration. Thus “Maxwell’s quaternion way of writing things” is not exactly
the same as a tensor-based reformulation of electrodynamics. The tensor version
of Maxwell’s equations (deriving E&M from the deformation of R4
geometry) describes the relationship between the electromagnetic potential Aµ (which, from the
perspective of quaternion operators, would be defined as a quadri-vector
potential), the electromagnetic field strength tensor Fµv (when Fµv = ωµv), and the current
tensor jµ, yielding the
“homogenous” form of Maxwell’s equations:
∂kFµv
+ ∂µFvk + ∂vFkµ = 0.
∂2Aµ = jµ ,
where ∂2 = ∂02
- ∂12- ∂22 - ∂32 = c-2∂t2 - ∇x2
“Gematric”, referring (adjectively) to the Jewish gematria and its many occult misuses of
mathematics and numbers.
Fascinating quote pertaining to “Duhem’s views of quaternions
and vector analysis”! Besides Cauchy and his stress tensor, I cannot think of
many French mathematicians and natural philosophers with a taste for the kind
of algebraic operations used in quaternion, vector, and tensor analyses.
Oh, I see. You were referring to relativity theory's tensorial
"simplification" of Maxwell's equations. To my knowledge, Duhem
never wrote about that (at least not directly, by writing
relativity's "'homogenous' form of Maxwell’s equations").
Re: "Duhem’s multi-layer thought and writings":
Duhem even spoke about Loti, Corneille, Shakespeare, and Dickens
in his Théorie physique. Duhem contrasts
Corneille with Shakespeare (∵ he considers both as not
strictly having an esprit de géométrie) and Loti
with Dickens (∵ both are prime examples of an esprit de géométrie). I read Tale of Two Cities
because I was curious if Dickens indeed has an "English mind" (esprit de géométrie), and he certainly does; I wasn't that impressed
with Tale of Two Cities because it didn't have much of an
"Ariadne's thread" (coherent idea/theme) running through it. It was
a disconnected smorgasbord of events and myriads of characters. As
Hertz said, Maxwell's theory is nothing more than Maxwell's
equations. Maxwell did not even derive these equations from a single
principle, like an energy law, which was customary to do in E&M
in the era between Ampére and Maxwell; thus, Maxwell's theory is an
example par excellence of the English/German/geometrical
mind, juggling many disconnected ideas around—which Poincaré said,
in that quote I sent you awhile back [translated on p. 8 of this], makes French minds ill-at-ease
when reading Maxwell for the first time.
Have you read any Corneille? I know he wrote Le Cid;
have you seen/read that? Does it exemplify the French esprit de finesse?
Duhem certainly is not opposed to analogies in physics.
Classification is impossible without the ability to form analogies,
and Duhem defines physical theory as a classification of
experimental laws (not a classification of equations!). Duhem
explicitly mentions "analogie" in Physique
du croyant p. 146 ff. (on the analogy between
cosmology [natural philosophy] and physical theory; Duhem
essentially proves Aristotle Physica 191a7-8: "The underlying
nature is known by analogy."), which you may have already
read. He describes very well what Fr. Wallace, O.P., says is the
"teaching that is distinctive of Thomism," i.e., that "analogical
middle terms are sufficient for a valid demonstration" (cf. this).
This is vital for there to be "mixed sciences" or scientia media,
where minor and major premises are taken from distinct fields, like
mathematics and physics, with distinct principles of their own. Fr. William A. Wallace, O.P., who pioneered
research into Galileo's logical treatises, describes this very well
in the best logic-of-science work I've ever read: The Modeling
of Nature (if Duhem wrote a logical work, which
I wish he did!, it would probably be similar to Fr. Wallace's).
Thus, what I think best describes "German" or "Jewish science" is
not that it uses analogy, which all physical theory does, but that
it's Neo-Pythagorean, inverting the 1st (physical) and 2nd (mathematical) degrees of abstraction. Duhem, where he
mentions Einstein in the La science allemande, makes it
clear that one cannot define time from a mathematical equation as
Einstein does. The inversion of the first two degrees of abstraction
has become so extreme that Max Tegmark, who is a hardcore
Pythagorean, even wrote a paper on the "Mathematical Universe Hypothesis," i.e., that the universe is mathematics!
Pythagoreans appear to be the first gematrists.
I was pleased to see Steiner
(2009) quote Peirce regarding analogies between physical
theories (p. 52fn9):
These universal super-laws were, to Peirce's thinking,
the key to the formal mathematical analogies we see between
laws—such as the inverse square laws in gravity and
electricity—analogies that demand explanation (7.509-7.511). But
Peirce looked to these super-laws also to explain, not only the
mathematical form of laws, but even the specific values of the
constants (like the gravitational constant) appearing in them.
This reminds me of what St. Thomas said is impossible in
that Super Iob quote I sent you, where he says some
things cannot have a natural explanation but are up to the will of
God. A "physical" theory being the analogy between two mathematical
laws is not a physical theory, but a mathematical one, at best, and
a confusing of mathematics with the will of God, at worst.
This reminds me: I need to read the article ["De Analogia
secundum Doctrinam Aristotelico-Thomisticam"] by Fr. Ramírez, O.P.,
that formed the foundation of his multi-volume De Analogia.
Fr. Rimírez is the master of analogy, and I'm curious what he has to
say about Duhem claim that (p.
147):
…si l'on prononce à cet endroit les mots de preuve
par analogie, il convient d'en fixer exactement le sens et
de ne point confondre une telle preuve avec une véritable
démonstration logique. Une analogie se sent ; elle ne se conclut
pas ; elle ne s'impose pas à l'esprit de tout le poids du principe
de contradiction. Là où un penseur voit une analogie, un autre,
plus vivement frappé par les contrastes des termes à comparer que
par leurs ressemblances, peut fort bien voir une opposition ; pour
amener celui-ci à changer sa négation en affirmation, celui-là ne
saurait user de la force irrésistible du syllogisme…
How is "preuve par analogie" not "une véritable
démonstration logique" thet "ne se conclut pas" and "ne
s'impose pas à l'esprit de tout le poids du principe de
contradiction"?
The
formalism of quaternions was very much Maxwellian in spirit and has actually been
extended in Germano-Anglo-American electromagnetic field theory on the basis of
the tensor field equations of Einstein. But it is the introduction of the
electromagnetic tensor field Fµv,
combined with the spin connection vector ωab
(the electrodynamics simplification of this amounts to equating F and ω by retranslating the
latter into a rotation tensor, ωµv)
that makes up for “relativity
theory’s tensorial "simplification" of Maxwell’s equations”,
which consists in the merging of electrodynamics with GR I was referring to (and
wondering whether Duhem had had any thought on this “tensorization” of E&M,
which is all the rage today among pan-relativists).
About
tragedians and the difference between “esprit
de finesses” and “esprit de géométrie”,
Duhem was probably keen on his contrasting assessment of Corneille and
Shakespeare on the one hand and Loti Dickens on the other. Corneille, as Molière,
also was a comedy writer and therefore, to my view, does exemplify something of
“un esprit de finesse”, since finesse
was rather characteristic of the kind of spirit 17th century French political/social
satires would famously convey through penetrating comedies (hardly the
under-the-belt level of our contemporary late wisecracking shows on T.V.).
Regarding
the centrality of analogies to the life of the created intellect, you correctly
write: “Classification
is impossible without the ability to form analogies”,
and logically justify the validity of Duhem’s definition of “physical theory as a classification
of experimental laws”, namely by way of analogous abstraction (which is what modeling
physical data in the logical formal of a physical theory really amounts to). In
a broader (cross-field) sense, I would define analogicity (ἀνα-λογία,
meaning quite literally the logic of
comparative relation between that which is lower to that which is higher) as a
critical way of both intuitively and intellectually seeing the similitude of
the invisible (the higher) mirrored in the visible (the lower). Both the Hebrew
word for intellectus (בִינָה,
“understanding” as the attitude of the intellect seeing in between two things,
meaning re-cognizing the like features by which two essentially distinct things
can coherently be related) and the Aramaic word for “comparison” (ܒ݁ܡܰܬ݂ܠܶܐ ,מתלא) clearly suggest that an analogy is actually
more than simply a ratio-nal
proportion (in the arithmetic, Aristotelian sense). In revealed anthropology,
it appears (my theory) that the created intellect (whose life is intellectus) is constitutionally analogic (together in inner structure and
cognitive motion).
I
did notice Duhem’s mention of analogy in Physique
du croyant. The distinction he makes
(referring to your final question) between “preuve
par analogie” and “une véritable
démonstration logique” does not imply that the first is less intellectually
powerful and epistemologically meaningful than the second. In fact, a mere
logical demonstration, however valid, may not have the same epistemological
value as a proof by analogy, even though the latter’s proof value is technically
more limited than a syllogistic demonstration. What this means is that analogical
knowledge is not reducible to logical validity. Thus a little like he did in La science allemande—first lesson (Les Sciences de Raisonnement)—when
distinguishing between axioms and theorems (which the following sentence on p.
6 summarizes like an aphorism: “Les principes se sentent, les propositions se
concluent…”), Duhem is essentially right to say on p. 147 of Physique du croyant: “Une analogie se
sent ; elle ne se conclut pas…”
The
confusion of degrees of abstraction you talk about is indeed critical! My sense
is that it is typically indulged in because there is actually more to numbers
and their multifaceted relations and properties than their simply being abstract
entities bereft of positive existence outside the mind (entia rationis).1 However, no one really knows how much
more, and what the true nature of this “more” is. That is the reason why mathematical
physics can really lead to ontological problems (as the nature of the 2nd
degree of abstraction is so evasive), but without possibly providing a
solution. If you remember, it was the sense of my comparative (analogical) “syllogism”
used here
to extend Gödel’s incompleteness results from mathematics to all-encompassing
Neo-Pythagorean physical theories whose ultimate Galilean assumption is that “the
universe is mathematics.”
“Duhem,
where he mentions Einstein in the La
science allemande, makes it clear that one cannot define time from a
mathematical equation as Einstein does.”
Yes,
and it is very significant that Newton did not include “time” in his descriptive
“universal super-law” of gravitation, while Einstein did. The Neo-Pythagorean
thinking undergirding GR and its inclusion of the time dimension times the
square root of - 1 was never meant to account for empirical results (contrary
to the regular claims appealing to the “countless corroborations” of the curved
geometry of Einsteinian gravitational field). GR was intended to provide a mathematical way out of the
contradiction between the instantaneous Newtonian gravitational field and the new
principles couched in the Einsteinian formulas pertaining to spacetime in SR (implying
action at a distance).
I
read Fr. Ramírez’s The authority of St.
Thomas, not his De Analogia.
