Occupation Doctor, philosopher

Gómez Pereira (1500–1567) was a Spanish philosopher, doctor, and natural humanist from Medina del Campo. Pereira worked hard to dispel medieval concepts of medicine and proposed the application of empirical methods; as for his philosophy, it is of the standard direction and his reasonings are a clear precedent of René Descartes. [1] He was the first to propose the famous " Cogito ergo sum ", in 1554, commonly attributed to Descartes. He was famous for his practice of medicine, although he had many diverse occupations, such as owning businesses, engineering, and philosophy.

Spain Kingdom in Southwest Europe

Spain, officially the Kingdom of Spain, is a country mostly located in Europe. Its continental European territory is situated on the Iberian Peninsula. Its territory also includes two archipelagoes: the Canary Islands off the coast of Africa, and the Balearic Islands in the Mediterranean Sea. The African enclaves of Ceuta, Melilla, and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country (Morocco). Several small islands in the Alboran Sea are also part of Spanish territory. The country's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar; to the north and northeast by France, Andorra, and the Bay of Biscay; and to the west and northwest by Portugal and the Atlantic Ocean.

Philosopher person with an extensive knowledge of philosophy

A philosopher is someone who practices philosophy. The term "philosopher" comes from the Ancient Greek, φιλόσοφος (philosophos), meaning "lover of wisdom". The coining of the term has been attributed to the Greek thinker Pythagoras.

Physician professional who practices medicine

A physician, medical practitioner, medical doctor, or simply doctor, is a professional who practises medicine, which is concerned with promoting, maintaining, or restoring health through the study, diagnosis, prognosis and treatment of disease, injury, and other physical and mental impairments. Physicians may focus their practice on certain disease categories, types of patients, and methods of treatment—known as specialities—or they may assume responsibility for the provision of continuing and comprehensive medical care to individuals, families, and communities—known as general practice. Medical practice properly requires both a detailed knowledge of the academic disciplines, such as anatomy and physiology, underlying diseases and their treatment—the science of medicine—and also a decent competence in its applied practice—the art or craft of medicine.

Biography

Not much is known of his life, because there was no one who took care of his manuscripts. What is known is the result of the investigation of unrelated documents to which researchers have given shape, many of them having to do with business or lawsuits.

Born in 1500 in Medina del Campo, he was the second of five brothers; his father, Antonia Pereira, owned a small shop of " xerguería," i.e., fabrics and low quality cloths. His mother, Margarita de Medina, died in 1515 and her sons went to the care of her aunt Ana de Avila. It is thought that Pereira descended from a family of converted Jews originally from Portugal, though this is not certain because the source of this was a neighbor that testified against him in a lawsuit.

Medina del Campo Municipality in Castile and León, Spain

Medina del Campo is a town located in the province of Valladolid, Castile and León autonomous region, 45 km from Valladolid. It is the capital of a farming area, far away from the great economic centres.

However, we cannot rule out this conversion because we know that, until his marriage, Pereira lived with his parents on Serrano street, which is located in the old Jewish quarter of town.

Pereira studied natural philosophy at the University of Salamanca with professor Juan Martínez Silíceo (who later became the archbishop of Toledo between 1545 and 1557). There, apparently, he was actively involved in the disputes between the realists and the nominalists, preferring the latter and rejecting the authority of the old masters in favor of knowledge provided by experience and reason. Here, he also studied medicine, concluding his studies 1520.

University of Salamanca Spanish university

The University of Salamanca is a Spanish higher education institution, located in the city of Salamanca, west of Madrid, in the autonomous community of Castile and León. It was founded in 1134 and given the Royal charter of foundation by King Alfonso IX in 1218. It is the oldest university in the Hispanic world and the third oldest university in the entire world still in operation. The formal title of "University" was granted by King Alfonso X in 1254 and recognized by Pope Alexander IV in 1255.

In metaphysics, realism about a given object is the view that this object exists in reality independently of our conceptual scheme. In philosophical terms, these objects are ontologically independent of someone's conceptual scheme, perceptions, linguistic practices, beliefs, etc.

He then returned to Medina where he established himself as a doctor. He married Isabel Rodriguez and lived on Rúa Nueva (now Padilla Street) where he worked as a doctor and managed the business that he inherited from his family. He possessed a considerable amount of capital and invested in a wide range of business including responsibility for making the actual income and managing the collection of several parishes, trading and warehousing wines, and renting rooms to other merchants who went to the "Great Exhibitions of the Kingdom" that took place in Medina.

His fame as a physician exceeded the boundaries of Medina, and he practiced in Burgos, Segovia, Ávila and other important cities of Castille. He even came to the court of Phillip II where he was summed to attend upon Prince Charles, heir to the unfortunate throne, who had suffered a serious accident. Thanks to Pereira, the Prince lived until 1568. He was also interested in the construction of hydraulic devices and, with his companion Francisco Lobato, designed a watermill dam that could function without water, which was patented in 1563.

Philip II of Spain 16th-century King of Spain who became King of England by marriage

Philip II of Spain was King of Castile and Aragon (1556–98), King of Portugal, King of Naples and Sicily, and jure uxoris King of England and Ireland. He was also Duke of Milan. From 1555 he was lord of the Seventeen Provinces of the Netherlands.

Carlos, Prince of Asturias Prince of Asturias

Carlos, Prince of Asturias, also known as Don Carlos, was the eldest son and heir-apparent of King Philip II of Spain. His mother was Maria Manuela of Portugal, daughter of John III of Portugal. Carlos was mentally unstable and was imprisoned by his father in early 1568, dying after half a year of solitary confinement. His fate was a theme in Spain's Black Legend, and inspired a play by Friedrich Schiller and an opera by Giuseppe Verdi.

In folio 26 of the Manuscripts of Francisco Lobato, the Medinan engineer decided to design a special mill, at the initiative of King Maxmilian II of Austria, who at the time was in Vallodolid (ca. 1550), a refugee from the wars against the Protestants. The future king of Bohemia took a fancy to go up the Douro River, so he commanded a galley be built and ordered the removal of any building that disrupted his navigation, i.e., fisheries and mills. This greatly harmed the locals who came to Lobato and Pereira to design a mill that could grind with the force of water without being directly on the river bank. Lobato goes on to explain that a model they tested on the Zapardiel River "milled and shook with reasonable force…, but it sucked in so much water that, by midday, there wasn't a single drop." Although the model was refined with a dam that returned the water to the river, the king paid no attention, and the project fell into oblivion. Lobato complained bitterly that, despite the promises of funding by the Habsburgs, "we have already spent 150 ducats…and he never paid me anything—someday I'll have to ask for it."

Pereira's unique thought arose from his synthesis of philosophy and medicine. He rejected the authority of the old masters and medievals in favor of reason, logic and experience. Moreover, he often used paradoxes and syllogisms to expose the errors of those he questioned. Thus, it can be argued that his philosophy was more negative than positive, but this is understandable considering the context of ideological suppression in the face of religious authority, as well the veiled accusations about Pereira's Jewish origins. The famous essayist Menéndez Pelayo wrote of this famous thinker:

In experimental psychology, Gómez Pereira is, without a doubt, more advanced than his time, more than the seventeenth century, more than Bacon, more than Descartes. None noted the phenomenon of his intelligence.

Novae veraeque Medicinae

Novae veraeque Medicinae is a medical treatise that focuses on the study of fevers [its causes and types] as well as other specific diseases like leprosy and smallpox. In this work, which he dedicated to Prince Don Carlos, Pereira challenges the tradition of Aristotle and Galen, as well as the medieval tradition of " magister dixit ". His is an entirely empirical and rational method, based in his experience as a physician. The healing methods are simple, and the doctor, because of his method and experience, is the final criterion of truth (as opposed to truths of religion or faith). "In no case of religious things will I give the opinion and sentence of some philosopher if it is not based on reason."

Gómez Pereira felt that the heat generated by a fever is the body's defense mechanism to remove the damage that affects it and, thus, nature restores the natural balance of any body, a surprisingly modern conception of fever as a reaction against disease. As for his studies of diseases such as leprosy or smallpox, Pereira's conclusions were later commended by the physician and historian Antonio Hernández Morejón.

Antoniana Margarita

Antoniana Margarita Antoniana-Margarita.png
Antoniana Margarita

Antoniana Margarita was reprinted many times but only very recently translated into Spanish (2000, from the original Latin). [2] The work is dedicated to his teacher Juan Martínez Siliceo and is a tribute to his parents, Antonio and Margarita, even though the subtitle of clearly indicates its scientific and philosophical contents: "a work so useful and necessary for medical, physical, and theologians ("Opus nempe phisicis, ac medicis teologis, non minus utile quam necessarium").

A difficult text to read because there are no chapters or paragraphs, the document uses the language of the "christianos nuevos" (New Christians) to explore new ideas from empiricism and materialism, possibly an effort to hide potentially controversial and blasphemous methods of reasoning (16th Century Castile, the Council of Trent had already begun). Thus, the Pereira did not venture to develop the logical conclusions to their fullest extent.

It is a philosophical treatise that addresses three key issues: the "automatism of beasts"; the theory of human knowledge; the immortality of the soul.

The insensibility of animals

Pereira's paradigm is typical of the Christian humanism of the Renaissance, denying that animals are equal to humans, while acknowledging some resemblance. Both have a body with five senses, but in the case of animals, the senses do not lead to knowledge, but cause automatic reactions. Indeed, many animals are capable of acting on internal impulses (soma), upon external stimuli (specie and phantasma), and have some non-conscious ability to learn (memoria). Nevertheless, Pereira denies animals the capacity for real knowledge: "bruta sensu carent."

The idea had many supporters, because, as indicated by the author himself, if animals feel just like humans, there would be nothing to differentiate, and if humans and animals are equal, animals can also learn about the Universal, which would be "absurd and impious." But he also had detractors, some of them very close. The physician Francisco de Sosa, who published in 1556 his work "Endecálago against Antoniana Margarita, in which is treated many and very sensitive reasons and authorities of the proofs of the feeling and movement of brutes."

Human knowledge

In this sense, Pereira's ideas are radically opposed to medieval scholasticism. He argues that knowledge enters through the sensory organs, as in animals, but only the human soul, its spirit, is capable of converting the information provided by the senses into real thought. This is one of the qualities of the soul, the ability to extract from physical sensations the substance of things (universals) through this process of abstraction. But Gómez Pereira believes that sensation and intellect go together in such a way that in human beings there is something that identifies the faculty of feeling with the quality of thought, in the same way, e.g., that thought and language are linked: "if you feel, you understand."

The immortality of the soul

Thus, knowledge would be an essential faculty of the soul, and, moreover, the human being has a soul conscious of itself, that exists thanks to the thoughts it develops. In this work (Antoniana Margarita), there is the phrase "I know that I know something, anyone who knows exists, then I exist" ("Nosco me aliquid noscere, & quidquid noscit, est, ergo ego sum"). [3] [4]

History has not recognized his contribution even though Descartes had already been accused of plagiarism in his time, for example by Pierre Daniel Huet. [5]

Although Pereira recognizes that animals have souls, it dies with them. The human soul, however, is self-sufficient and thus immortal. He provides three proofs that he claims had not been discovered. First, because of its consciousness, the human soul is capable of knowing independent of the body, and thus is capable of existing despite the body's death. Secondly, the human soul does not change even though the body ages or becomes diseased, that is, its essence is not affected by extrinsic factors. Thirdly, it is the desire of all humans to attain happiness, which, alongside the wish to know the future and the consequences of our actions, are the reasons that prompt us to do good, because evil deeds lead to punishment and misfortune.

Pereira and Descartes

After René Descartes published his Discourse on Method in 1637, the originality of the thoughts was questioned and even said to be an overt plagiarism of Gómez Pereira, as the Spanish philosopher had been studied by many prestigious intellectuals during the 16th and 17th Centuries.

The first to suggest the similarities between the two was Pierre Daniel Huet, originally a follower then an opponent of Cartesian philosophy. Descartes himself was forced to defend himself against these accusations, as is evidenced by a letter he wrote in 1641 to his friend Father Marin Mersenne:

I have not seen Antoniana Margarita, nor do I have a great need to see it any more than the Theses of Louvain or the book of Hansenius, but I would like to know where to find a copy if you think it necessary.

Many scholars of the 17th and 18th Centuries sided with Descartes and despised the work of Pereira, among them Pierre Bayle (although he did recognize the similarity between the two) and the Enclyopedists Diderot and d'Alembert who said:

Descartes is the first philosopher who dared to consider animals as mere machines: therefore, Gómez Pereira, who said this some time before him . . . stumbled upon this hypothesis by chance.

However, many others have defended the contrary thesis. Even accepting that Descartes may not have read the work of Pereira, they argue that he was influenced indirectly, especially through the work of another Spanish physician and philosopher, Francisco Valles, who read it in French. Among those who accuse Descartes of being a counterfeit are Isaac Cardoso and Voltaire.

The basis for this criticism is the striking similarities between the two thinkers on some key points:

  1. The empirical method: Descartes' is a priori and deductive, whereas Pereira's is a posteriori and inductive.
  2. Souls of animals: for both, it is a material soul, limited and mortal
  3. The "automatism of beasts": whereas Descartes says that animals have a body, mind and memory, Pereira says the same using different language, viz., animals have internal structure or soma, external stimuli or phantasmae, and the ability to learn or memoria.
  4. The basic syllogism is strikingly similar in both, the "Cogito ergo sum" ("je pense, donc je suis") of Descartes versus the "quidquid noscit, est, ergo ego sum" of Pereira (which precedes Descartes by some one hundred years).

<i>Cogito, ergo sum</i> philosophical proposition by René Descartes

Cogito, ergo sum is a Latin philosophical proposition by René Descartes usually translated into English as "I think, therefore I am". The phrase originally appeared in French as je pense, donc je suis in his Discourse on the Method, so as to reach a wider audience than Latin would have allowed. It appeared in Latin in his later Principles of Philosophy. As Descartes explained, "we cannot doubt of our existence while we doubt...." A fuller version, articulated by Antoine Léonard Thomas, aptly captures Descartes's intent: dubito, ergo cogito, ergo sum. The concept is also sometimes known as the cogito.

Epistemology A branch of philosophy concerned with the nature and scope of knowledge

Epistemology is the branch of philosophy concerned with the theory of knowledge.

René Descartes 17th-century French philosopher, mathematician, and scientist

René Descartes was a French philosopher, mathematician, and scientist. A native of the Kingdom of France, he spent about 20 years (1629–1649) of his life in the Dutch Republic after serving for a while in the Dutch States Army of Maurice of Nassau, Prince of Orange and the Stadtholder of the United Provinces. One of the most notable intellectual figures of the Dutch Golden Age, Descartes is also widely regarded as one of the founders of modern philosophy.

Skepticism or scepticism is generally a questioning attitude or doubt towards one or more items of putative knowledge or belief or dogma. It is often directed at domains, such as the supernatural, morality, theism, or knowledge. Formally, skepticism as a topic occurs in the context of philosophy, particularly epistemology, although it can be applied to any topic such as politics, religion, and pseudoscience.

Reason is the capacity of consciously making sense of things, establishing and verifying facts, applying logic, and changing or justifying practices, institutions, and beliefs based on new or existing information. It is closely associated with such characteristically human activities as philosophy, science, language, mathematics and art, and is normally considered to be a distinguishing ability possessed by humans. Reason, or an aspect of it, is sometimes referred to as rationality.

In philosophy, rationalism is the epistemological view that "regards reason as the chief source and test of knowledge" or "any view appealing to reason as a source of knowledge or justification". More formally, rationalism is defined as a methodology or a theory "in which the criterion of the truth is not sensory but intellectual and deductive".

Islamic philosophy

Islamic philosophy is a development in philosophy that is characterised by coming from an Islamic tradition. Two terms traditionally used in the Islamic world are sometimes translated as philosophy—falsafa, which refers to philosophy as well as logic, mathematics, and physics; and Kalam, which refers to a rationalist form of Islamic theology.

Early Islamic philosophy or classical Islamic philosophy is a period of intense philosophical development beginning in the 2nd century AH of the Islamic calendar and lasting until the 6th century AH. The period is known as the Islamic Golden Age, and the achievements of this period had a crucial influence in the development of modern philosophy and science. For Renaissance Europe, "Muslim maritime, agricultural, and technological innovations, as well as much East Asian technology via the Muslim world, made their way to western Europe in one of the largest technology transfers in world history.” This period starts with al-Kindi in the 9th century and ends with Averroes at the end of 12th century. The death of Averroes effectively marks the end of a particular discipline of Islamic philosophy usually called the Peripatetic Arabic School, and philosophical activity declined significantly in Western Islamic countries, namely in Islamic Spain and North Africa, though it persisted for much longer in the Eastern countries, in particular Persia and India where several schools of philosophy continued to flourish: Avicennism, Illuminationist philosophy, Mystical philosophy, and Transcendent theosophy.

<i>Discourse on the Method</i> book by Descartes

Discourse on the Method of Rightly Conducting One's Reason and of Seeking Truth in the Sciences is a philosophical and autobiographical treatise published by René Descartes in 1637. It is best known as the source of the famous quotation "Je pense, donc je suis", which occurs in Part IV of the work. A similar argument, without this precise wording, is found in Meditations on First Philosophy (1641), and a Latin version of the same statement Cogito, ergo sum is found in Principles of Philosophy (1644).

<i>Meditations on First Philosophy</i> philosophy book by Descartes

Meditations on First Philosophy in which the existence of God and the immortality of the soul are demonstrated is a philosophical treatise by René Descartes first published in Latin in 1641. The French translation was published in 1647 as Méditations Métaphysiques. The title may contain a misreading by the printer, mistaking animae immortalitas for animae immaterialitas, as suspected by A. Baillet.

Self-reflection humanitys search for intrinsic meaning and purpose

Human self-reflection is the capacity of humans to exercise introspection and the willingness to learn more about their fundamental nature, purpose and essence.

In philosophy, the Cartesian Self, part of a thought experiment, is an individual's mind, separate from the body and the outside world, thinking about itself and its existence. It is distinguished from the Cartesian Other, anything other than the Cartesian self. According to the philosopher Rene Descartes, there is a divide intrinsic to consciousness, such that one cannot ever bridge the space between one's own consciousness and that of another.

<i>Nous</i> the faculty of the human mind necessary for understanding what is true or real

Nous, sometimes equated to intellect or intelligence, is a term from classical philosophy for the faculty of the human mind necessary for understanding what is true or real. English words such as "understanding" are sometimes used, but three commonly used philosophical terms come directly from classical languages: νοῦς or νόος, intellēctus and intellegentia. To describe the activity of this faculty, the word "intellection" is sometimes used in philosophical contexts, as well as the Greek words noēsis and noeîn. This activity is understood in a similar way to the modern concept of intuition.

French philosophy, here taken to mean philosophy in the French language, has been extremely diverse and has influenced Western philosophy as a whole for centuries, from the medieval scholasticism of Peter Abelard, through the founding of modern philosophy by René Descartes, to 20th century philosophy of science, existentialism, phenomenology, structuralism, and postmodernism.

<i>Passions of the Soul</i> book

In his final philosophical treatise, The Passions of the Soul, completed in 1649 and dedicated to Queen Christina of Sweden, René Descartes contributes to a long tradition of philosophical enquiry into the nature of "the passions". The passions were experiences – now commonly called emotions in the modern period – that had been a subject of debate among philosophers and theologians since the time of Plato.

Cartesianism philosophical and scientific system of René Descartes

The Cartesian Method is the philosophical and scientific system of René Descartes and its subsequent development by other seventeenth century thinkers, most notably François Poullain de la Barre, Nicolas Malebranche and Baruch Spinoza. Descartes is often regarded as the first thinker to emphasize the use of reason to develop the natural sciences. For him, the philosophy was a thinking system that embodied all knowledge, and expressed it in this way:

Cartesian doubt form of methodological skepticism associated with the writings and methodology of René Descartes

Cartesian Doubt is a form of methodological skepticism associated with the writings and methodology of René Descartes. Cartesian doubt is also known as Cartesian skepticism, methodic doubt, methodological skepticism, universal doubt, systematic doubt or hyperbolic doubt.

Common sense set of widely accepted beliefs

Common sense is sound practical judgment concerning everyday matters, or a basic ability to perceive, understand, and judge that is shared by nearly all people. The first type of common sense, good sense, can be described as "the knack for seeing things as they are, and doing things as they ought to be done." The second type is sometimes described as folk wisdom, "signifying unreflective knowledge not reliant on specialized training or deliberative thought." The two types are intertwined, as the person who has common sense is in touch with common-sense ideas, which emerge from the lived experiences of those commonsensical enough to perceive them.

Floating man, flying man or man suspended in air is a thought experiment by Avicenna to argue for the existence of the soul. The argument is used to argue for the knowledge by presence.
