«Universalmente admirada es la soberbia figura moral del hidalgo manchego. D. Alonso Quijano el bueno, convertido en andante caballero por la sugestión de los disparatados libros de caballería, representa, según se ha dicho mil veces, el más perfecto símbolo del honor y del altruismo. Jamás el genio anglo-sajón, tan dado á imaginar caracteres enérgicos y originales, creó personificación mas exquisita del individualismo indómito y de la abnegación sublime. Pero puntualicemos brevemente los rasgos psicológicos sobresalientes del protagonista de la novela inmortal.….

This compilation brings together 20 essays of Santiago Ramón y Cajal (1852-1934), the neuroscientist par excellence and 1906 Nobel Laureate in Medicine, on topics beyond neuroanatomy, most appearing in English for the first time. The annotated collection makes available in one handy volume Cajal's ideas on psychology, art and education, still current and still relevant, derived from his books La Psicología de los Artistas, Charlas de Café, El Mundo Visto a los Ochenta Años, Pensamientos Pedagógicos and (...) Escritos Inéditos. An acute observer of the intellectual and social scene of the avant-garde, Cajal emerged in 20th-century Spain in a further role as a philosopher and educator. The contents bespeak Cajal's inquiry into the varieties of human experience and shed new light on the breadth of his genius, imagination and passion, helping us to rethink what we thought we already understood about Don Santiago's own mind.

En octubre de 1944, nueve meses antes de su fallecimiento, Pío del Río Hortega pronunció en Montevideo una conferencia en el Homenaje a Ramón y Cajal en el décimo aniversario de su muerte organizado por la Institución Cultural Española de Uruguay.

Cajal realizó un soberano esfuerzo para que la ciencia de España figurase entre las naciones próceres de Europa. La teoría neuronal de Cajal ha significado una verdadera revolución no sólo en la histología sino también en la fisiología. La moderna tecnología electrónica también es cajalista.

En el desarrollo de las ciencias naturales, el siglo XVIII mostró, entre otras características, el intento de levantar el inventario del reino de los seres vivos. Pero es claro que la actividad de clasificar y sistematizar equivale a una descripción analítica de la naturaleza y presupone un prolijo y paciente estudio de datos y de hechos; de ahí que no sorprenda que la abrumadora cantidad de detalles predispusiera a los investigadores a descuidar un tanto la búsqueda de lo universal en (...) la naturaleza.….

Se intenta poner de manifiesto, en este artículo, a través de un somero análisis de la biografía y de la obra de Santiago Ramón y Cajal, como su contribución a la historia de la histología no fue un fruto del azar, sino de una profunda investigación propiciada por su deseo de saber.

El artículo es un breve análisis del discurso de Santiago Ramón y Cajal titulado Psicología de Don Quijote y el quijotismo, un texto poco conocido que fue una de las piezas principales producida en torno al tema con motivo del III centenario del Quijote. El discurso de Ramón y Cajal le fue encargado por el Colegio Médico de San Carlos, y se pronunció en Madrid el día 9 de Mayo de 1905. Las ediciones existentes contienen (...) algunas erratas e inexactitudes. Nuestro análisis expone las ideas de Ramón y Cajal en relación con la situación de la ciencia española y con los remedios que es necesario poner en práctica y con el espíritu que debe animarlos para poner luego en relación las ideas de Ramón y Cajal con las de Unamuno y Ortega, los dos principales autores españoles que escribieron sobre el tema en aquellos mismos años, subrayando la coincidencia entre Unamuno y Ramón y Cajal y la llamativa distancia de Ortega con las ideas de nuestro histólogo en relación con la ciencia.

This study presents abundant empirical evidence to sustain that the genius of Santiago Ramón y Cajal was the result of a conscious effort of self-construction, the key factors of which were psychosocial, some of which are also found in other highly creative scientists. In this case, new factors appear that have not been observed in other geniuses, such as a substantial vicarious and self-regulating capacity and a high degree of perceived self-efficacy. The procedure used is the narrative (...) analysis of essentially autobiographic texts. The theoretical framework on which the study is based is the psychology of science and Bandura cognitive-social theory. (shrink)

Santiago Ramón y Cajal, the primary architect of the neuron doctrine and the law of dynamic polarization, is considered to be the founder of modern neuroscience. At the same time, many philosophers, historians, and neuroscientists agree that modern neuroscience embodies a mechanistic perspective on the explanation of the nervous system. In this paper, I review the extant mechanistic interpretation of Cajal’s contribution to modern neuroscience. Then, I argue that the extant mechanistic interpretation fails to capture the (...) explanatory import of Cajal’s law of dynamic polarization. My claim is that the definitive formulation of Cajal’s law of dynamic polarization, despite its mechanistic inaccuracies, embodies a non-mechanistic pattern of reasoning (i.e., design explanation) that is an integral component of modern neuroscience.

In this article we scrutinize what can be called an "experimentalist dogma" presupposed in Pablo Melogno's analysis of empirical incommensurability in the chemical revolution. According to Melogno, the fact that experimental methods were preserved throughout the chemical revolution was an indication that there were no relevant perceptual differences between Joseph Priestley and Antoine Lavoisier. In order to refine Melogno's general analysis, we will present a taxonomy of varieties of empirical incommensurability and discuss their relationships. To exemplify this categorization, and to (...) show its metatheoretical adequacy, we will apply it to the neuronist revolution, that is, to the process of discovery of the neuron in the late 19th and early 20th centuries within neuroanatomy, taking as our main case study the controversy between Camillo Golgi and Santiago Ramón y Cajal. From the analysis of the controversies regarding dendritic spines and stellate cells of the cerebellum, in particular, we question the experimentalist dogma, highlighting how, in these controversies, the conservation of experimental practices does not guarantee the similarity of perceptual contents. Moreover, we will argue that, all other experimental conditions being equal, differences in experiential content between Golgi and Cajal are best explained by differences in their commitments to incompatible conceptual schemes.

El artículo analiza el nacimiento de la Junta para Ampliación de Estudios e Investigaciones Científicas (JAE) como primer planteamiento de diseñar y estructurar la política científica y la investigación en España y su continuidad tras la guerra civil con la creación del CSIC y, tras la democracia, el diseño de una política científica puesta al servicio de los españoles.

In his work, Michael Ruse underscores the significance of metaphors in science, with a particular focus on the “abyss” between mechanistic and organicist metaphors in the history and practice of biology. Ruse posits that the Darwinian revolution involved a radical “metaphor shift” in biology, transitioning from organicism to mechanism. In this article, I set out several objectives (i) to assess whether the neuronist revolution, pivotal in the inception of neuroscience, involved a shift from an organicist metaphor to a mechanistic one; (...) (ii) to highlight the indispensable influences of organicist metaphors in Cajal’s neuron doctrine; and, consequently, (iii) to challenge the idea of an abyss between mechanistic and organicist metaphors, at least, in neuroscience.

En este trabajo sostengo que la concepción mecanicista no captura la relevancia explicativa de la ley de polarización dinámica de Cajal. La relevancia explicativa de la ley se fundamenta en su rol como principio de diseño neuronal. Como tal, la ley nos brinda acceso epistémico a intervenciones ideales, conceptualmente posibles, sobre la localización de los diversos componentes de los centros nerviosos, y nos permiten evaluar el impacto de esas intervenciones sobre las condiciones de viabilidad del organismo.

Love, fear, hope, calculus, and game shows-how do all these spring from a few delicate pounds of meat? Neurophysiologist Ian Glynn lays the foundation for answering this question in his expansive An Anatomy of Thought, but stops short of committing to one particular theory. The book is a pleasant challenge, presenting the reader with the latest research and thinking about neuroscience and how it relates to various models of consciousness. Combining the aim of a textbook with the style of a (...) popularization, it provides all the lay reader needs to know to participate in the philosophical debate that is redefining our attitudes about our minds. Drawing on the rich history of neurological case studies, Glynn picks through the building blocks of our nervous system, examines our visual and linguistic systems, and probes deeply into our higher thought processes. The stories of great scientists, like Ramon y Cajal, and famous patients, like Sperry's split-brained epileptics, illuminate the scientific issues Glynn selects as essential for understanding consciousness. Some might argue that his lengthy explorations of natural selection overemphasize evolutionary explanations of psychological phenomena, but they must also agree that evolutionary psychology has distanced itself mightily from social Darwinism in recent years and merits a reappraisal. The great consciousness debate may form the core of the 21st-century Zeitgeist; get ready for it with An Anatomy of Thought. -Rob Lightner From Publishers Weekly How do we know? What do we think? How could a philosophical problem-'the mind-body problem,' say-induce a headache? What can evolutionary theory, molecular biology, the history of medicine and experimental psychology tell us about the features of human consciousness, and (once again) how do we know? Glynn, a physician and Cambridge University professor, meticulously attempts to answer these questions and more, setting forth the results of all sorts of research relevant to our brains-from 19th-century dissections to Oliver Sacks-like case studies, work with monkeys and supercomputers, and the enduring puzzles of philosophy, which he rightly saves for near the end. After explaining evolution by natural selection and 'clearing away much dross,' Glynn lays out the experiments and theories that have shown 'how nerve cells can carry information about the body, how they can interact' and how sense organs work; demonstrates the 'mixture of parallel and hierarchical organization' in our brains and 'the striking localization of function within it'; considers where neuroscience is likely to go; and admits that, among the many fields of exciting research just ahead, 'we can be least confident of progress toward a complete, scientific explanation of our sensations and thoughts and feelings.' Other recent explaining-the-brain books have sometimes advanced simplistic, or implausibly grand, claims about the nature and features of consciousness in general. Instead, Glynn offers a patient, informative, well-laid-out researcher's-eye view of what we have learned, how we figured it out and what we still don't know about neurons, senses, feelings, brains and minds. (Apr.) Copyright 2000 Reed Business Information, Inc. From Library Journal The nature of consciousness, which perennially troubles the minds of scientists and philosophers, is the subject of an ever-growing body of literature. Two of the latest entries approach the topic from different perspectives. Glynn, a professor of physiology and head of the Physiological Laboratory at Cambridge, offers a comprehensive summary of what we know about the brain-both its evolution and its mechanisms. Among the topics he covers are natural selection, molecular evolution, nerves and the nervous system, sensory perception, and the specific structures responsible for our intellect. Using the mechanisms involved in vision and speech as models, Glynn skillfully describes various neurological deficiencies that can lead to 'disordered seeing' and problems with the use of language. He carefully distinguishes what we know through experimental evidence from what we know through the observation of patients with neurological damage. He also describes some of the major theories that attempt to explain why these structures arose. While his book concentrates on the structures that make up the mind, Glynn is well aware that some physical events appear explicable only in terms of conscious mental events-a situation that conflicts with the laws of modern physics. Only briefly, however, does he consider the various approaches that have been taken to deal with the issues of mind/body and free will. In contrast, this is the primary focus of The Physics of Consciousness. After reviewing the fundamentals of classic physics, Walker (who has a Ph.D. in physics) summarizes elements of the new physics in which our knowledge of space, time, matter, and energy are all dependent on the moment of observation. Walker explores the meaning of consciousness as a characteristic of the observer. In this context both the observer and the act of measurement are critical. In essence, Walker leads his reader on a journey through his concept of a 'quantum mind,' which can both affect matter (including other minds) and can be affected by other distant matter/minds. To break up what would otherwise be an extremely dense text, Walker also relates the very touching story of the loss of his high-school sweetheart to leukemia. Indeed, it is his memory of their relationship that drives Walker to seek an understanding of ultimate reality. At times, he has a tendency to be dogmatic-as when he concludes, 'our consciousness, our mind, and the will of God are the same mind.' While An Anatomy of Thought is appropriate for most academic libraries, the Physics of Consciousness will be most accessible to readers with some knowledge of advanced physics. -Laurie Bartolini, Illinois State Lib., Springfield Copyright 2000 Reed Business Information, Inc. From Booklist The codiscoverers of natural selection-Charles Darwin and Alfred Wallace-disagreed over the possibility of finding an evolutionary explanation for the human mind. Glynn here argues Darwin's side of the debate, tracing an eons-long path of development starting from simple amino acids floating in primal seas and extending through the erect hominids in which the powers of a massive brain first manifest themselves. Patiently adducing evidence of an evolutionary origin for the underlying molecular machinery, Glynn dissects the nerve centers that make possible speech and hearing, sight, and reading. Pressing deeper, he lays bare the cortical foundations of personality. But those who deal with the mind must attend also to the arguments advanced by philosophers. And it is when he turns from dendrites to syllogisms (especially the vexing mind-body paradox) that Glynn's empirical reasoning fails him. In the end, he concedes his perplexity in trying to conceive of an evolutionary origin for human consciousness. This concession may set the shade of Alfred Wallace to chortling, but it will draw readers into an honest confrontation with a profound enigma. Bryce Christensen. (shrink)

In the beginning of the 20th century the groundbreaking work of Ramon y Cajal firmly established the neuron doctrine, according to which neurons are the basic structural and functional units of the nervous system. Von Weldeyer coined the term “neuron” in 1891, but the huge leap forward in neuroscience was due to Cajal’s meticulous microscopic observations of brain sections stained with an improved version of Golgi’s la reazione nera (black reaction). The latter improvement of Golgi’s technique made it (...) possible to visualize the arborizations of single neurons that were “colored brownish black even to their finest branchlets, standing out with unsurpassable clarity upon a transparent yellow background. All was sharp as a sketch with Chinese ink”. The high quality of both the visualization of individual nerve cells and the work performed on studying the anatomy of the central nervous system lead Ramon y Cajal to the conclusion that axons output the nervous impulses to the dendrites or the soma of other target neurons.

First of all, we would like to gratefully thank all commentators for the attention and effort they have put into reading and responding to our review paper [this issue] and for useful observations that suggest novel applications for our framework. We understand and accept that some of our claims might appear controversial and raise skepticism, because the overall neural framework we have proposed is difficult to frame in established categories, given its strong multidisciplinary character. To make an example, Elsevier is (...) publishing the British Neuroscience Association (BNA) 2017 Special Issue Collection. However, our paper could not fully fit in any of their Special Issues—attention, motivation, behavior; sensory and motor systems; novel treatments and translational neuroscience; genetics and epigenetics; learning and memory; neurodegenerative disorders and ageing; developmental neuroscience; neuronal, glial and cellular mechanisms; neuroendocrine and autonomic nervous systems; psychiatry and mental health; methods and techniques. Perhaps because our paper was mathematically, physically, biologically (neuroscientifically), and phenomenologically motivated from the start? Nevertheless, venturing in novel, fresh, testable proposals is badly needed in contemporary neuroscience, so to break into “the utter darkness of the inner mechanism of psychic acts… during the production of the concomitant phenomena of perception and thought, namely, feelings, consciousness and volition”—as Cajal had already observed in his opus magnus ‘Textura’. But as he soberly confessed: “This ideal is still very distant” (Ramon y Cajal, 1899-1904, p. 1,141). In the pursuit of that very ideal, neuroscience and psychology have had, and continue to have, a plethora of movements and schools of thought: behaviorism, cognitivism, neural Darwinism, social constructivism, Bayesian optimization...In our paper, we propose to go a step further, via the notion of topodynamics, towards “projectionism.” In what follows, trying to elucidate the main features of this Emperor’s new clothing, we proceed with the responses to the comments received.

Suele señalarse la fuerte influencia que la teología natural tuvo sobre Darwin en su conceptualización del fenómeno de la adaptación. La teoría de la selección natural explicaría el mismo fenómeno que los teólogos naturales querían explicar: la adaptación. Recientemente ha sido señalado, sin embargo, que la forma darwiniana de conceptualizar la adaptación es novedosa. Las adaptaciones de la teología natural presupondrían la idea de que los organismos existen para la realización y manutención del equilibrio natural establecido por el creador. El (...) punto de este trabajo discutir esta cuestión, asumiendo el marco del estructuralismo metateórico. The strong influence that natural theology had over Darwin’s conceptualization of the adaptation phenomenon is frequently noted. The natural selection theory would explain the same phenomenon that the natural theologist intended to explain: the adaptation. Recently has been claimed, on the contrary, that the Darwinian way of conceptualizing adaptation is new. The concept of adaptation from natural theology presupposes the idea that organisms exist for realization and support of the natural equilibrium stated by the creator. In this work I will discuss this point, assuming the metatheoretical structuralism frame. (shrink)

The scientific revolution of the XVII siècle is normally described as erasing final causes and the teleology of physics. Nevertheless, the functional language plays a central role in certain areas of biological practice. This is why many philosophers have tried to explicate the concept of function, sometimes to defend the relevance of its use, some other times to show that it is merely a way of speaking that could be easily eliminated without any relevant information loss. The principal purpose of (...) this paper is to show the necessity of appealing to functional concepts for an adequate reconstruction of the Darwinian natural selection theory. Thus, functional language is used in the conceptualization of the theory’s domain of application, and that domain should be determined independently of the natural selection theory. (shrink)

Resumen: Usualmente se ha asumido que una única distinción puede dar cuenta del rol que cumplen los conceptos en una teoría respecto de la contrastación y respecto de la explicación. Intentaremos mostrar que esta asunción es incorrecta.

La base de contrastación de una teoría no tiene por qué coincidir con el (...) explanandum de la teoría. Para defender este punto se asumirá el estructuralismo metateórico. Se extraerán consecuencias para la concepción metateórica presupuesta. Palabras claves: Explicación; contrastación; T-teoricidad; Estructuralismo metateórico; Distinción teórico observacional -/- Title: Explain and test Abstract: It is usually held that one distinction can account for the role that concepts play in a theory regarding both test and explanation. We will demonstrate that this assumption is incorrect. On the one hand, there is no reason to think that this coincidence should exist. On the other, this is not the case, as we will show analysing several examples. The testing basis of a theory does not have to coincide with the explanandum of the theory. To defend this point we will endorse de metatheoretical structuralism. In addition, we will consider some repercussions that this discussion has for the assumed metatheoretical framework.

La discusión acerca de funciones es de larga data en filosofía. Normalmente se describe a la revolución científica del siglo XVII como eliminando las causas finales y la teleología de la física. Sin embargo, el lenguaje funcional cumple un papel central en ciertas áreas de la práctica biológica. Esto ha llevado a muchos filósofos a intentar elucidar el concepto de función, en algunos casos para defender la relevancia de estos usos, en otros para mostrar que se trata de meras formas (...) de hablar que podrían ser eliminadas sin pérdida de ningún tipo de información relevante. El objetivo principal de este trabajo es mostrar la necesidad de apelar a conceptos funcionales para una reconstrucción adecuada de la teoría de la selección natural darwiniana. Pues, se utiliza lenguaje funcional en la conceptualización del campo de aplicación de esta teoría, y tal campo debe ser determinable con independencia la teoría de la selección natural. (shrink)

Para algunos la selección natural se identifica con las diferencias de éxito de distintos organismos en la reproducción diferencial. Si esto fuese así, el principio de Hardy-Weinberg, por permitir determinar con bastante precisión bajo ciertos supuestos que la frecuencia génica en una población no es la esperada, podría ser visto como una versión cuantitativa de la selección natural cualitativa propuesta por Darwin.
