Nasr and the Illusion of Conspiracy in the Scientific Community
Ata Kalirad, evolutionary biology researcher at the Institute for Research in Fundamental Sciences
«به تماشا مینشینی و میپرسی چرا، اما من آنچه را که نبوده است تجسم میکنم و میپرسم چراکه نه؟»
جرج برنارد شاو، بازگشت به متوشالح
به عقیده جان مینارد اِسمیت (2004-1920)، زیستشناس و تکاملدان برجسته انگلیسی، در نمادگرایی و تصادف (۱۹۸۱) علت اصلی سردرگمی شمار بسیاري از مردمان، ازجمله اندیشمندان، در برابر نظریه تکامل زیستی ماهیت این نظریه به مثابه روایتی در باب آفرینش است؛ برخلاف غالب روایات متعددی که در فرهنگهای مختلف در باب خلقت موجودات زنده مطرح میشود، نظریه تکامل زیستی فاقد هرگونه معنای نمادین است و راه را بر تفاسیر مختلف میبندد و روایتی که به دست میدهد تمامی سازوکارها و وقایع مورد نیاز برای وقوع چنین روایتی را آشکارا در برابر ما قرار میدهد.
این توضیح و توضیحات دیگر شاید توضیح دهند که چرا افراد اندیشمند گهگاه در فهم و درک نظریه تکامل ناتوانند. البته ناتوانبودن از فهم برخی مفاهیم یک حوزه علمی بههیچروی شرمآور نیست و تمامی علمورزان نیز تنها در حوزه محدودی توانایی دارند و از درک عمیق بسیاری از موضوعات علمی عاجزند، اما استفاده از این جهل بهمثابه داربستی برای برافراشتن نقدی بر این موضوعات و حوزههای علمی از عجایبی است که بیشتر، شاید به واسطه پیامدهای فلسفی آن، درخصوص نظریه تکامل زیستی صادق است.
دیدگاههای متفکری مانند سیدحسین نصر در باب تکامل زیستی گرچه شاید در چارچوب سنتگرایی بگنجد، اما بهتنهایی براي هر آن کس که حتی آشنایی سطحی با این مباحث داشته باشد، سرگیجهآور است. پروفسور نصر که صرفا چند واحد زیستشناسی را در دوران تحصیلش در دانشگاه امآیتی گذرانده است، خود را مجاز میداند که شاکله زیستشناسی مدرن در تمام دانشگاههای معتبر دنیا را نقد کند. وی در جوان مسلمان و دنیای متجدد، اظهار میکند که «... در زمینه مطالعه و طبقهبندی انواع گیاهان و حیوانات همچنان زیستشناسی ارسطویی مبنای مطالعات زیستشناختی است». (ص ۲۶۷)؛ کمترین آشنایی با نظام طبقهبندی موجودات زنده و گردشی سرسری در میان صفحات کتب مرجع زیستشناسی در سطح دبیرستان، ناآگاهی گوینده را هویدا میکند.
در جایی دیگر میفرمایند که «علیرغم آنهمه شواهد زیستشناختی در رد و ابطال نظریه تکامل [...] هنوز این انتقادات چندان جدی گرفته نمیشوند» (ص ۲۷۰). همانند تمامی متون همسنگی که در این باب نگاشته شدهاند، نصر علاقه چندانی به فهرستکردن شمهای از این شواهد نیز ندارد و چنان مینگارد که گویی این پیشفرض واقعیتی مسلم بوده و نیازی به گشودن این مسئله نمیبیند. این باور نصر به توطئهای نظاممند در مراکز علمی غرب به منظور سرکوب اشاعه هرگونه نظری در رد تکامل زیستی در اسلام، علم، مسلمانان و فناوری عریانتر بیان میشود. چنین باوری در میان هواداران طراحی هوشمندانه در ایالات متحده نیز بسیار رایج است و بیشتر ناشی از عدم آشنایی و تسلط به زبان فنی این حوزه است تا انعکاسی از واقعیت موجود و ماهیت نشر پژوهشهای علمی. بهعنوان کسی که چندی در بطن این رشته در غرب تحصیل و پژوهش کردهام باید بگویم که علمورزان در رقابتی دائم به منظور انتشار پژوهشهای انقلابیاند و نشریات برجسته علمی نیز همواره در پی انتشار چنین پژوهشهایی به منظور جلب هرچه بیشتر توجه. پروژه دانشنامه عناصر دِنا
(ENCODE) نمونهای بسیار جالب از چنین پدیدهای است: نتایج مرحله دوم این پژوهش در ۲۰۱۲ در قالب ۳۰ مقاله مختلف، از جمله شش مقاله در نشریه نِیچِر، منتشر شدند و ادعای اصلی این پژوهش مبنیبر عملکرد زیستی بخشهای عمدهای از ژنوم انسان (مجموعه محتوای ژنتیکی موجود در هر یاخته پیکر انسان) با برخی فرضهای ژنتیک جمعیت که از عمودهای خیمه تکامل است، جور درنمیآمد و همین مسئله منجر به انتشار مجموعهمقالات در نشریات مختلف در این خصوص شد و بحثی طولانی در این باب در میان زیستشناسان حوزههای مرتبط در گرفت که بخشی از آن تا به امروز نیز ادامه دارد.
Many such examples can easily be found in the history of evolutionary thought; for instance, the school of neutralism, from the 1960s onward, with the research of Motoo Kimura (1924–1994), emphasized the ineffectuality of the majority of accumulated molecular changes during evolution on the fitness of organisms, and it was highly prevalent in the 1970s and 80s. However, sustained criticism of this view, along with the production of a vast amount of biological data, led to the emergence of the nearly neutral model; this debate over the role of natural selection in molecular changes is still ongoing, and in June 2018, a special issue of the prestigious journal Molecular Biology and Evolution (MBE) was dedicated to the critique and examination of neutral molecular evolution in light of new data and new models. Certainly, such a dynamic atmosphere of critique and exchange of ideas will have no place within the conspiracy delusion of Nasr and his ilk. The main issue is that proposing a new model and critiquing previous models in a field of science requires a deep mastery of the fundamental concepts of that field; a characteristic clearly not found in the critique of a scholar like Nasr.
Nasr apparently also cannot abide the reductionism present in the theory of biological evolution and, as a logical critique, remarks, “Do they [meaning evolutionists] ever think for a moment about how the greatest masterpieces of literature, such as the works of Dante and Shakespeare, could arise from a molecular soup?” (p. 164). In scientific methodology, the rule is that when discussing and examining questions, one should not confuse the limitations of an individual’s imagination with the limitations of the proposed mechanism. The fact that the imagination of the writer of these lines—who is not a pastry chef—cannot conceive of the transformation of flour, sugar, and other ingredients into a mille-feuille pastry is not a logical reason for the impossibility of this transformation.
Nasr’s reading of the theory of evolution, which clearly bespeaks a deep and extensive ignorance regarding the theory of evolution, raises a serious question in the author’s mind: Is Nasr fundamentally ignorant on this matter and also lacking any desire to understand this issue, or does his intellectual framework compel him to such a bizarre interpretation of evolution?

Nasr and the History of Science in Islamic Civilization
Amir-Mohammad Gamini. Assistant Professor, Institute for the History of Science, University of Tehran
Professor Seyyed Hossein Nasr is one of the leading figures of the Traditionalist movement. His numerous works critiquing modern civilization and extolling the outlook he calls “Tradition” have been translated and published in many languages, including Persian. Nasr is not only a critic of modern science and an enthusiast for ancient science, but his academic training is in the history of science. A look at Nasr’s many writings on the history of science can not only reveal the degree of historical and scientific precision in his and his fellow thinkers’ work, but may also shed light on useful points in the methodology of the historiography of science.
It could perhaps be said that David King (b. 1941), the prolific and renowned historian of Islamic astronomy and mathematics, was the first to warn of the numerous errors, blind citations, and misunderstandings in one of Nasr’s general works on the history of Islamic science. King, who examined only the astronomical section of the book Science in Islam (translated by Ahmad Aram), wrote:
“This work, which [contrary to its claim] has not engaged in the ‘research and analysis’ of any text, is replete with claims lacking sufficient evidence and with obvious mistakes. Most of Nasr’s statements referring to a particular person, work, or discovery contain some kind of distortion or exaggeration that indicates his unfamiliarity with primary sources or with the mathematical and astronomical sciences…. This is not a book written by an amateur; the author is a professor of the history of science…. It seems that his connection to the current research field in the discipline of the history of science is entirely severed (King, David. ‘A Critique and Review of the Astronomical and Mathematical Chapters of Seyyed Hossein Nasr’s Science in Islam.’ Journal of the Scientific Heritage of Iran and Islam. (5) 1, serial no. 9, 1395: p. 103).”
King, who focused on the scientific errors in the astronomical section of the book, said of Nasr’s statement that “the unity of the cosmic sciences [in Islam] branches from the epistemic fabric of the Quranic revelation” (on the cover): such claims should be “considered more a personal interpretation and impression than historical research” (King: 103). He quotes a passage from Nasr’s book that merits further reflection:
“Muslims possessed all the necessary technical knowledge to overthrow the Ptolemaic system, including knowledge of the heliocentric system, but they did not do so, because they had forgotten neither the symbolic significance of traditional astronomy nor the fact that the best way to remind most human beings of the Divine Presence is to remind them of the limitations of the created universe (Nasr, Science in Islam, p. 143 / 133a).”
Let us see what this passage means. It seems Nasr wants to say that Muslim scientists were not in search of discovering the scientific and natural truths of the universe. They apparently had a more important task, which was religious preaching, and they wanted to use their scientific theories to turn the hearts of Muslims toward God. Certainly, Islamic scientists had many religious motivations in their scientific activities and valued contemplation of the divine signs. But is it not an insult to the entirety of those scientists’ scientific and religious activities to suppose that they did not prioritize scientific objectivity and, due to religious motivations, did not tell people the truth? Professor Nasr does not limit himself to this statement about new scientific theories, and elsewhere in his book claims that the astronomers of sixteenth- and seventeenth-century Europe were able to arrive at the heliocentric theory because “... they lived in a cosmos that had already lost its religious coloring and had taken on a secular and non-religious hue, and they reached results that differed greatly from those of the Muslims, who drew upon both their own ideas and astronomical instruments” (p. 56). From this it becomes clear that Nasr is not only unaware of even the religious motivations behind the scientific activities of astronomers such as Copernicus, Galileo, and Kepler, but also considers the only path to progress and transformation in science to be the abandonment of religion and religious beliefs.
Muzaffar Iqbal, in his interview with Professor Nasr, asks about King’s critique of his book and receives the answer that yes, “King led to a few minor corrections… and I am grateful to him for that… although the more important matter is the overall perspective within which I have examined the history of Islamic science” (Nasr, Islam, Science, Muslims, and Technology, Elmi va Farhangi Publications, 1396: p. 89). Thus, Nasr does not attach great importance to his technical inaccuracies and considers the main value to lie in his ideological message. But is this not precisely what separates a meticulous, cautious researcher with epistemic integrity from other high-profile but hollow professors?
Another example of Nasr’s technical inaccuracies in the field of the history of science is the entry on “Qutb al-Din al-Shirazi” that he wrote for the Dictionary of Scientific Biography (Gillispie (ed.)).
I have shown in another piece (Journal of the History of Islamic Civilization, Vol. 48, No. 2, Fall and Winter 2016) that Nasr thinks Shaykh Shihāb al-Dīn Suhrawardī's Philosophy of Illumination has something to do with the science of optics, or geometrical optics, and by virtue of this delusion, imagines that Quṭb al-Dīn Shīrāzī, who wrote a commentary on the Philosophy of Illumination, must also have great achievements in the science of optics. The result is that Nasr falls into a deep misunderstanding in comprehending those few pages that Shīrāzī devoted to geometrical optics in his astronomical book Nihāyat al-idrāk fī dirāyat al-aflāk; such that he mistakes Shīrāzī's simple analysis of a ray of light entering a room and reflecting around it for an advanced theory about the formation of the rainbow. Of course, Quṭb al-Dīn Shīrāzī's achievements in the science of hayʾa (astronomy) are very valuable, and I have introduced a corner of them in detail in my book, The Minaʾi Circles: A Study in the History of Cosmology in Islamic Civilization. Furthermore, a time-consuming examination is needed to determine the extent of the scientific errors present in Nasr's other works, including the book Science and Civilization in Islam; a task that the author of these lines may undertake in the future, but here we can return to Nasr's general view on the history of Islamic science.
Parvez Hoodbhoy, a physicist at MIT, in his book Islam and Science (published by the Institute for Humanities Research and Development, 2005), has strongly opposed Nasr's criticisms of modern science. But, most regrettably, Hoodbhoy agrees with Nasr on this point that "the determinate function of the natural sciences [of the Islamic era] was teleological and sought the divine order of the cosmos, whose main coordinates were revealed through revelation (Hoodbhoy, pp. 164-5)." I have shown elsewhere, in a critique of the book The Formation of Islamic Science, that one cannot say that the sciences of Islamic civilization were derived from Islam or were wholly placed in the service of theology (Quarterly Book Review on Kalām, Philosophy and Mysticism, No. 15-16, Fall and Winter 2018). Of course, religious rulings had raised new scientific problems for mathematicians, such as determining canonical times and the direction of the qibla, but neither were the main scientific activities of scholars for religious purposes, nor did solving such problems mean the closure of the path to free scientific inquiry. Incidentally, religious needs provided a pioneering motivation for thinking about various new mathematical problems that the Greek predecessors of Islamic scientists had not considered.
I certainly do not deny that Islamic scientists held metaphysical and even mythical views about the universe; many scientists of the Islamic period, in their theological or philosophical works, spoke of the hierarchies of being, vertical causation, the souls of the spheres, and numerous metaphysical and theological theories. Nevertheless, the study of their scientific works shows that they did not involve their theological views in their scientific activity. They saw no need to introduce theological presuppositions into scientific work in order to preserve their religious and philosophical beliefs. Even if these metaphysical presuppositions sometimes appeared, they did not detract from the scientific nature of their achievements (refer to my book The Minaʾi Circles, Hekmat-e Sina Publication: pp. 29-40).
Nasr's conception of the science of Islamic civilization causes him not to observe fairness in his judgment about modern science either. He cannot accept that "according to the modern understanding of science, whether scientists believe in God or not has no bearing on the science they pursue." In his view, "the entire procedure of modern science is based on forgetting the spiritual aspect present in nature, and this means severing God's hands from His creation." He therefore finds fault with why an atheist physicist and a Catholic physicist jointly win the Nobel Prize in Physics (Nasr, 2017: p. 86). But does modern science and the understanding of the secrets of existence through non-religious methods really lead to the irreligiosity of the youth? Was the science of Islamic civilization, which Nasr introduces as the model of Islamic sciences, less non-religious than modern sciences? Did the irreligiosity of scientists like Zakariyyā al-Rāzī prevent him from entering scientific activities? Can a point be found in the sciences of Islamic civilization where a scientist's religious faith directly or even indirectly entered the content of his scientific work? Is it not strange that Muslims were the inheritors of the sciences of polytheistic Greek scientists like Euclid and Ptolemy? In reality, neither were the sciences of Islamic civilization religious, nor is modern science anti-religion. If anything causes the youth to turn away from religious beliefs, it is precisely these pronouncements of Nasr.
Nasr's simplistic thinking about the content of the sciences of Islamic civilization reveals itself in other points as well, in comparison with modern science. For example, he complains that "[modern] cosmological theories... change every few years” (Nasr, 2017: p. 92). This remark, coming from someone with an education in the history of science, is very strange. The history of science is the history of developments and revolutions in scientific theories. In Islamic civilization, too, we witness the presentation of new theories and even revolutions; for example, Ibn al-Haytham’s scientific revolution in optics and the critiques of the Maragha school astronomers of Ptolemaic planetary models, which led them to present new planetary models every few years (see The Minaret Circles: Chapter Two). But is change and transformation in science not a necessity of it? And can anything but a dogmatic outlook expect stasis from science and its history?

Dinosaurs and Their Feathers
Erfan Khosravi. Paleontologist
Hossein Nasr’s most serious critique of the theory of evolution in Religion and the Order of Nature revolves around two axes: 1) the denial of biological teleology and the extension of a mechanistic conception to the realm of life. Both charges, of course, from the perspective of modern biology, are a compliment that brings honor and standing; but Nasr also resorts to other claims in order to portray evolution as an unscientific topic and the standard-bearer of an ideology of atheism.
A False Dilemma
In the notes to the fourth chapter of Religion and the Order of Nature, he considers “the most virulent form of atheism endorsed by science” to arise from evolutionary biology, and brings as evidence a comparison between “someone like Stephen Hawking [sic] and Richard Dawkins.” This divergence between the theory of evolution and theism, which is a point of agreement between Nasr and Dawkins, is, in the view of many other biologists and philosophers, even an atheist philosopher like Elliott Sober, a false dilemma arising from a misunderstanding.2 Some of Nasr’s other interpretations of Darwin’s views also continue to demonstrate his superficial understanding of the subject. For example, in Religion and the Order of Nature, Nasr says that the evolutionary account “transformed the longitudinal hierarchy of the chain of life or the chain of being, which was usually conceived ‘spatially’—that is, as ever-present—into a temporal and horizontal chain.” Although a kind of longitudinal hierarchy of the chain of life existed in the minds of naturalists before Darwin, this notion that Darwin’s theory rearranged the ladder of life along the axis of time is one of the most important common misunderstandings about the theory of evolution.3
The Zeno-Nasr Paradox
Nasr, who began his education in the field of geology, claims to be well acquainted with the theory of evolution and its scientific flaws. In the same book, he acknowledges that his aim is “not to present a metaphysical, religious, logical, or even scientific critique of the theory of evolution,” but immediately speaks of the “logical-metaphysical meaninglessness [unreasonableness]” of this theory and also of the “vast body of paleontological evidence indicating the sudden appearance of various species.” Besides Nasr, many other critics of the theory of evolution have also claimed that what is found in fossils, in their view, never indicates a sequence of gradual changes.4 This group of critics of the theory of evolution always emphasizes the minute and major differences among various organisms, especially fossils thought to be related to present-day creatures, and claims: “These differences could not have changed gradually.” In fact, people like Nasr who argue based on the “vast body of paleontological evidence indicating the sudden appearance of various species” are deploying a modern version of Zeno of Elea’s paradoxes. Just as Zeno argued that swift-footed Achilles would never overtake his slow-moving rival, the tortoise, in a race, critics of the theory of evolution say, “Such-and-such a fossil is so different from such-and-such present-day animals that it cannot be reached through evolutionary changes.” The simplest answer to this criticism is similar to the answer given to the Achilles and the tortoise paradox: some infinite series that tend toward zero have a finite sum; therefore, not only can Achilles overtake the tortoise in a finite time, but present-day living organisms can also have evolved from the lineage of different organisms in the past. The important point that should not be forgotten in the evolutionary version of Zeno’s paradox (it is better to call it the Zeno-Nasr paradox) is that all the colorful and multidimensional manifestations of life are a crystallization of the linear sequence of nucleic acids (DNA and RNA); therefore, the minute and major differences among various organisms are reducible to differences in the sequence of their hereditary code, and when we measure this difference, we realize that the difference between some apparently distinct species is very slight. This means that, in a finite time, chance mutations alongside natural selection (which non-randomly eliminates some mutations and preserves others) can create such a difference and transform one genome into another. If we accept that the genetic structure of all past organisms on Earth was probably similar to that of present-day organisms, it is natural to be able to claim, for example, that today’s toothless birds evolved from an ancestor that had teeth, especially if we know that the genes encoding tooth structure still exist in the genome of birds; but because the promoter sequence for these genes is silenced, today’s birds have become toothless.
این حقیقت به علاوه نشان میدهد روند تکامل، همواره از طریق کمترین تغییرات ژنتیک انجام شده و مثلا برای اینکه نیای دنداندار پرندگان در تکامل بیدندان شود، سادهترین جهش ممکن (خاموششدن توالی راهانداز) کافی بوده است؛ اما آیا میتوان به همین شیوه استدلال کرد که پرندگان از نسل موجوداتی با ظاهر کاملا متفاوت تکامل یافتهاند؟
پدربزرگ پردار و پیش از او
آرکیوپتریکس (Archaeopteryx) پرنده سنگوارهای است که در سال ۱۸۶۰ کشف شد و بهخاطر داشتن بالهایی با سه انگشت پنجهدار، دم بلند سوسمارمانند و آروارهای دنداندار، بهعنوان ابتداییترین پرنده و شاهد تکامل پرندهها از نسل دایناسورها معرفی شد. در دهههای پایانی سده بیستم، مخالفان نظریه تکامل ادعا کردند آرکیوپتریکس فاصله ریختشناختی زیادی با هر دو دسته دارد و نمیتواند خویشاوند هیچکدام باشد. دیدیم که دستکم از نظر ژنتیک تغییرات بسیار جزئی در ژنوم آرکیوپتریکس میتواند به تکامل پرندگان بیدندان منتهی شود، اما با توجه به اینکه تقریبا درباره ساختار ژنوم دایناسورها هیچ نمیدانیم۵، درباره ارتباط ریختشناسی آرکیوپتریکس و دایناسورها چه میتوان گفت؟ در پاسخ به این ادعا، مقاله پژوهشی جالب ریختشناختی آرکیوپتریکس را با دایناسورهایی که نوعا خویشاوندان این پرنده شمرده میشوند، مقایسه و روند انباشت این یافتههای سنگوارهای را نیز در دهههای ۱۹۲۰ تا ۲۰۱۰ میلادی بررسی كرد. این مقاله با استفاده از مقایسههای ریختشناختی موردعلاقه مخالفان نظریه تکامل اما با اتکا به دادههای یافتشده در دهههای اخیر، نشان داد در دهههای آغازین سده بیستم، انواع کشفشده دایناسورها آنقدر نادر بودند که فاصله ریختشناختی زیادی بین آرکیوپتریکس و دایناسورها به چشم بیاید، اما تا ۲۰۱۰، آنقدر انواع مختلف دایناسورهای ریزودرشت کشف شدند که بتوان سیر تکامل آرکیوپتریکس از دایناسورهای متعارف را قدمبهقدم در این سنگوارههای نویافته تماشا کرد۶. برخلاف ادعای حسین نصر و خلقتگرایان مسیحی، این یافتههای دیرینهشناختی حاکی از ظهور دفعی گونهها نیست؛ بلکه مسیر تغییرات تکاملی بهقدری کامل کشف شده که در عمل عبارتهایی مثل «حلقه گمشده»۷ منسوخ شدهاند.
تکامل عضو نامربوط
اما فنیترین نقدی که نصر به نظریه تکامل ارائه میکند، مربوط به پیدایش سازگاریهایی از قبیل بال پرندگان است که تنها در حالت کامل میتواند برای پرواز استفاده شود، اما ضروری است که از صورتی ابتداییتر تکامل یافته باشد که به درد پرواز نمیخورد: «وقتی شما پرندهای را در حال پرواز میبینید، هیچ منطقی برای این فرض وجود ندارد که بال بهتدریج از یک عضو نامربوط به پرواز ایجاد شده باشد»۸. این همان پرسشی است که جرج میوارت، زیستشناس معاصر داروین و منتقد نظریه انتخاب طبیعی، طرح کرده بود. میوارت مثل داروین قائل به تکامل بود، منتها با سازوکار انتخاب طبیعی موافق نبود. پاسخهای نظری محکمی در 60 سال اخیر به این اشکال داده شده که از همه جامعتر، پاسخ گولد و وربا بود که نشان دادند سازگاریهای تکاملی، میتوانند پس از اینکه برای مقصود خاصی انتخاب شدند و توسعه یافتند، در ترکیب با سازگاریهای دیگر یا شرایط جدید، نقشهای تازهای بپذیرند۹. بال پرندگان نمونه خوبی از اندامهایی است که به قول نصر از «عضوی نامربوط» تکامل یافته، ولی بهرغم نصر و همفکران او، منطقی قوی این فرایند را تشریح و توجیه میکند. نمونه مشهور دیگری که ساختاری پیچیده از تکامل و پیوستگی اجزای نامربوط متفاوت تکامل یافته، تاژک باکتریهاست. در تاژک باکتریها بیش از 20 نوع پروتئین مختلف وجود دارد که ظاهرا بدون برخی از آنها، تاژک کاملا غیرفعال و بیفایده است. اغلب منتقدان تکامل میپرسند چگونه ممکن است 20 نوع پروتئین مختلف همزمان جهش یافته و مورد انتخاب طبیعی قرار گیرند، درحالیکه اگر 19تای آنها جهش مییافتند و یکی که مهمتر بود، جهش نمییافت، تاژکی غیرفعال و بیفایده به وجود میآمد که نمیتوانست مورد انتخاب طبیعی قرار بگیرد. در پاسخ باید گفت اولا همه پروتئینهای تاژک برای عملکرد آن ضروری نیستند و حذف برخی از آنها، تنها عملکرد تاژک را کاهش میدهد و البته برخی جهشهای دیگر هم هستند که ممکن است عملکرد تاژک را از حالت طبیعی فعلی حتی بهبود دهند. Therefore, the structure of the flagellum in bacteria is not even in a fully optimal state, but rather in a “relatively optimal” condition. More importantly, however, the structure of almost all flagellar proteins is similar to independent proteins that have a singular, natural function outside the flagellum; for instance, the motor portion of the flagellum appears to be a type of specialized protein pump for ion transport, which, before assuming a motor role in the flagellum, was selected for and evolved by natural selection as a structure for transporting ions (across the cell membrane). Just as with the bacteria whose protein pumps ended up in the structure of the flagellum, thanks to the feathered dinosaurs discovered in just the last two or three decades, we know that the wing, too, in fact evolved from an unrelated organ (the arm) in the body of dinosaurs; dinosaurs of various sizes, from half a meter to 10 meters, whose bodies were covered in feathers. In some specimens, the feathers served only to keep the body surface warm, and in others, they grew as long, quill-like feathers from around the tail and the back of the hands. These quill-like feathers gave the dinosaurs' hands an appearance similar to the wings of modern birds, but their structure is completely non-aerodynamic and useless for flying. The feathers of these dinosaurs show that non-flight quill feathers were selected for by natural selection for a purpose other than flight, including attracting the attention of the opposite sex for mating. The final step in the emergence of flight wings was only a slight change in the proportion and dimensions of the feathers, so that display wings evolved into a tool that, in addition to attracting attention, could also be used for flying.10

Nasr and Modern Science
Mohammad Reza Tavakoli-Saberi. Author and translator of scientific works
After Galileo turned his astronomical telescopes toward the sky and released his balls down inclined planes, he set off a tremendous revolution in science and philosophy—a revolution that continues to this day. Before that, philosophers studied the world and existence through rational and logical methods and interfered in the experimental work of scientists. Galileo’s important achievement was to show that the method of observation and experiment holds the upper hand in understanding nature and must ultimately test the validity of the rational method. In doing so, he made humanity more aware of the powerful tool of experiment and experience, enabling a better explanation of the natural world than before. A tool that allowed humans to see the farthest galaxies and the tiniest organisms, and to travel to the heights of the skies and the depths of the oceans.
Nevertheless, even in our age there are those who do not see this immense power and this great achievement, and who try to belittle them. They prefer the pre-Galilean world—a world in which everything was interconnected. The Earth was the center of the universe and the other planets revolved around it. The celestial spheres determined human destiny, diseases were caused by humors or the influence of the stars upon humans, and enemas, fumigations, and herbal concoctions cured all human illnesses. The scholars and sages of the past were wiser and more comprehensive than contemporary scientists because their knowledge encompassed a wide spectrum of learning. The driving factor behind these individuals’ outlook is their specific ideology, philosophy, and religious perspective.
Dr. Seyyed Hossein Nasr is one of those who has written numerous books and articles on the history and philosophy of science in Islam and is among the Traditionalists who believe that the Islamic world needs Islamic science—that is, a type of scholarship built upon Islamic foundations and beliefs. Dr. Nasr considers the modern experimental sciences to be entirely separate from the definition of science, and even deems the pursuit of them un-Islamic and condemns it. In his article “Islam and Science,” Dr. Nasr states: “Many Muslims have tried to show that Islam, unlike Christianity, is not in conflict with science, but what they meant by science was knowledge in the sense of wisdom and the traditional sciences, not the modern sciences.” (Book: Islam and Contemporary Society) Dr. Nasr believes that modern sciences are incompatible with Islam because they cause young people to lose faith in religion. In his view, science must possess characteristics that do not destroy the faith of Muslims. He believes that “the sciences produced by Muslims in no way challenged Islam or Islamic scholarship in the manner of modern sciences. They did not abandon their prayers the way today’s students abandon their religious duties upon studying mathematics or chemistry. Something very important separates the modern sciences of today from the traditional sciences of the past. This ‘something’ lies at the heart of the problem of the confrontation between Islam and modern sciences. Until this ‘something,’ or the factors that separate modern sciences from traditional sciences, is identified and understood, there is no hope of resolving the threat and challenge posed by modern sciences to the traditional sciences and the Islamic worldview. No matter how much the existence of this problem is denied and it is said that Islam is in agreement with science, this does not prevent the spread of this secular science, whose foundation rests upon the forgetting of God, nor does it prevent the erosion of the foundations of the edifice of Islamic faith.” (Same source)
Another aspect of Dr. Nasr’s opposition to modern sciences is the reductionism of science. He says that Islam cannot accept the reductionism of the sciences and their reduction into more specialized branches, because these sciences reduce metaphysics to psychology, psychology to biology, biology to chemistry, and chemistry to physics, thus bringing all elements of reality down to the lowest level of manifestation, namely the physical realm. Dr. Nasr’s objection to the reductionism of scholarship is unwarranted, because this division does not conflict with Islamic science. Did not the scholars of Islam, over successive centuries, make science more specialized and branched? Did they not make algebra and arithmetic more specialized, or, as they themselves have said, separate pharmacology from medicine? If that same scientific tradition of Muslims had continued until now, Muslims would probably have followed the same path as Christians. Science is a dynamic and active human endeavor and cannot fail to grow and develop. Even now, it is impossible for anyone to study all branches of physics or astronomy, let alone other fields such as medicine, theology, and philosophy, as the Islamic and Christian sages and scholars once did.
In his book Science and Civilization in Islam, Dr. Nasr says that in the history of Islam, the central and principal figure in the transmission of science was the wise man or hakim.
A hakim was usually a physician, writer, or poet. In the figure of the hakim one can observe the unity of all sciences, as he would teach various branches of knowledge. The hakim or polymath, Dr. Nasr, corresponds to those scholars or Renaissance men, one of the last and finest examples of whom was the Italian Leonardo da Vinci, whose artistic works in painting and sculpture and scientific works in mechanics, physics, and other fields of human knowledge were far more advanced than those of many Islamic sages of his time and after them.
Dr. Nasr is so immersed in and enamored of the past that he ultimately disregards the achievements of knowledge and thought over the past four centuries, considering them a negative trait for human beings because they have been emptied of their metaphysical burden. Instead of taking pride in and boasting about the science of the past, Dr. Nasr and his like would do better to devote their efforts to encouraging modern science in various fields (especially the theoretical sciences), so that perhaps in the long run someone might emerge to reconcile Islamic metaphysics with the new scholarship. Scholarship cannot subordinate itself to metaphysics; rather, it is metaphysics and the supernatural that are influenced by scholarship and adapt themselves to it. Santillana is therefore right in saying that if Abu Rayhan had been in the place of Copernicus or Galileo, he would have done the same as they did, which is a sign of the truth-seeking of genuine scholars, regardless of philosophical and religious considerations, in the process of scientific discovery.
نام آقای نصر تنها نام ایرانی در فهرست صد فیلسوف زنده جهان است،اما شهرت ایشان در غرب به دلیل رویکرد ایشان در مواجهه با مشکلات و بحرانهای جهان مدرن میباشد.در واقع ایشان برای غربی که در مدرنیسم غوطه ور است،حرفی برای گفتن دارد(حتی مهم نیست که نظر او درست یا اشتباه باشد،همین که طرح مسئله میکند برای آنها غنیمت است).اما تردید نباید کرد که استقبال از ایده های ایشان در جایی مانند ایران که هنوز در حال چالش با سطحی ترین ابعاد مدرنیته است و کمتر درکی از اعماق این زیست جهان دارد،حرکتی ضد فرهنگی و نوعی ضدیت با پویش ترقی خواهانه علمی صنعتی جامعه ایرانی است.

منظور حضرت عالی آن است که حتما باید صبر کنیم تا به همان جهان مدرنیته پیشرفته غرب برسیم و با آفات این مدرنیته مواجه شویم و بعد حرفهای نصر را گوش بدهیم؟!یعنی علاج واقعه قبل از وقوع نکنیم؟!!

انگاره های ضدعلمی نصر به ویژه از طریق شاگردان و پیروانش مانع رشد علم در ایران بوده است . نقد نصر هر چند دیرهنگام اما ضروری و ستودنی است .
