Query: Who are the three most important eastern philosophers?
The "Dao De Jing" ("Tao-Te-Ching," c. 4th century BCE), traditionally attributed to Laozi, and the "Nan Hua Jing" ("Zhuang Zi") are considered the key texts of the tradition. The first organized form of Taoism, the Tianshi (Celestial Masters') school arose in the 2nd century CE. Xuanxue ("deep learning", also "Neo-Taoism") was a major philosophical movement influenced by Confucian scholarship, which focused on the interpretation of the "Yijing," "Daodejing," and "Zhuangzi" and which flourished during the third to sixth centuries CE. The most important philosophers of this movement were He Yan, Wang Bi, the Seven Sages of the Bamboo Grove, Ge Hong and Guo Xiang. Thinkers like He Yan and Wang Bi focused on the deep nature of Tao, which they saw as being best exemplified by the term "Wu" (nothingness, non-being, negativity).
Dualism is a set of views about the relationship between mind and matter (or body). It begins with the claim that mental phenomena are, in some respects, non-physical. One of the earliest known formulations of mind–body dualism was expressed in the eastern Sankhya and Yoga schools of Hindu philosophy (c. 650 BCE), which divided the world into purusha (mind/spirit) and prakriti (material substance). Specifically, the Yoga Sutra of Patanjali presents an analytical approach to the nature of the mind.
Confucius (551–479 BCE) appeared in this period of political decadence and spiritual questioning. He was educated in Shang-Zhou theology, which he contributed to transmit and reformulate giving centrality to self-cultivation and human agency, and the educational power of the self-established individual in assisting others to establish themselves (the principle of 愛人 "àirén", "loving others"). As the Zhou reign collapsed, traditional values were abandoned resulting in a period of moral decline. Confucius saw an opportunity to reinforce values of compassion and tradition into society. Disillusioned with the widespread vulgarisation of the rituals to access Tian, he began to preach an ethical interpretation of traditional Zhou religion. In his view, the power of Tian is immanent, and responds positively to the sincere heart driven by humaneness and rightness, decency and altruism. Confucius conceived these qualities as the foundation needed to restore socio-political harmony. Like many contemporaries, Confucius saw ritual practices as efficacious ways to access Tian, but he thought that the crucial knot was the state of meditation that participants enter prior to engage in the ritual acts. Confucius amended and recodified the classical books inherited from the Xia-Shang-Zhou dynasties, and composed the "Spring and Autumn Annals".
Platonism was originally expressed in the dialogues of Plato, in which the figure of Socrates is used to expound certain doctrines, that may or may not be similar to the thought of the historical Socrates, Plato's master. Plato delivered his lectures at the Academy, a precinct containing a sacred grove outside the walls of Athens. The school continued there long after Plato's death. There were three periods: the Old, Middle, and New Academy. The chief figures in the Old Academy were Speusippus (Plato's nephew), who succeeded him as the head of the school (until 339 BC), and Xenocrates (until 313 BC). Both of them sought to fuse Pythagorean speculations on number with Plato's theory of forms.
While Western philosophical traditions, as exemplified by Descartes, equate mind with the conscious self and theorize on consciousness on the basis of mind/body dualism; some Eastern philosophies provide an alternate viewpoint, intimately related to substance dualism, by drawing a metaphysical line between consciousness and matter — where matter includes both body and mind.
What was later to be known as Plato's school probably originated around the time Plato inherited the property at the age of thirty, with informal gatherings which included Theaetetus of Sunium, Archytas of Tarentum, Leodamas of Thasos, and Neoclides. According to Debra Nails, Speusippus "joined the group in about 390 BC". She claims, "It is not until Eudoxus of Cnidos arrives in the mid-380s BC that Eudemus recognizes a formal Academy." There is no historical record of the exact time the school was officially founded, but modern scholars generally agree that the time was the mid-380s, probably sometime after 387 BC, when Plato is thought to have returned from his first visit to Italy and Sicily. Originally, the meetings were held on Plato's property as often as they were at the nearby Academy gymnasium; this remained so throughout the fourth century.
The study of the mind in Eastern philosophy has parallels to the Western study of the Philosophy of mind as a branch of philosophy that studies the nature of the mind. Dualism and monism are the two central schools of thought on the mind–body problem in the Western tradition, although nuanced views have arisen that do not fit one or the other category neatly. Dualism is found in both Eastern and Western traditions (in the Sankhya and Yoga schools of Hindu philosophy as well as Plato) but its entry into Western philosophy was thanks to René Descartes in the 17th century. This article on mind in eastern philosophy deals with this subject from the standpoint of eastern philosophy which is historically strongly separated from the Western tradition and its approach to the Western philosophy of mind.
The first recorded school of anatomy was in Alexandria from about 300 to the 2nd century BC. Ptolemy I Soter was the first to allow for medical officials to cut open and examine dead bodies for the purposes of learning how human bodies operated. On some occasions King Ptolemy even took part in these dissections. Most of the early dissections were done on executed criminals. The first use of human cadavers for anatomical research occurred later in the 4th century BCE when Herophilos and Erasistratus gained permission to perform live dissections, or vivisection, on condemned criminals in Alexandria under the auspices of the Ptolemaic dynasty. Herophilos in particular developed a body of anatomical knowledge much more informed by the actual structure of the human body than previous works had been. Herophilos was the first physician to dissect human bodies and is considered to be the founder of Anatomy. He reversed the longstanding notion made by Aristotle that the heart was the "seat of intelligence". He argued instead that this seat was the brain. He established the brain as the center of intelligence, distinguished between veins and arteries, and made many other accurate observations about the structure of the human body, especially the nervous system. However, Herophilos was eventually accused by his contemporaries of dissecting live criminals. The number of victims is said to be around 600 prisoners.
During the second half of the first millennium BC, the Ancient Greeks developed differing views on the function of the brain. However, due to the fact that Hippocratic doctors did not practice dissection, because the human body was considered sacred, Greek views of brain function were generally uninformed by anatomical study. It is said that it was the Pythagorean Alcmaeon of Croton (6th and 5th centuries BC) who first considered the brain to be the place where the mind was located. According to ancient authorities, "he believed the seat of sensations is in the brain. This contains the governing faculty. All the senses are connected in some way with the brain; consequently they are incapable of action if the brain is disturbed...the power of the brain to synthesize sensations makes it also the seat of thought: The storing up of perceptions gives memory and belief and when these are stabilized you get knowledge." In the 4th century BC Hippocrates, believed the brain to be the seat of intelligence (based, among others before him, on Alcmaeon's work). During the 4th century BC Aristotle thought that, while the heart was the seat of intelligence, the brain was a cooling mechanism for the blood. He reasoned that humans are more rational than the beasts because, among other reasons, they have a larger brain to cool their hot-bloodedness.
In Plato's Gorgias (and in the Protagoras 345c4-e6), Socrates argues that no one does wrong willingly, one of the most famous doctrines to be associated with him. When framed in modern (Western) terms, the implication is that it is ignorance, rather that free individual agency, that is responsible for morally wrong actions.
Several Oxyrhynchus Papyri fragments were found to contain parts of the Republic, and from other works such as Phaedo, or the dialogue Gorgias, written around 200-300 CE. Fragments of a different version of Plato's Republic were discovered in 1945, part of the Nag Hammadi library, written ca. 350 CE. These findings highlight the influence of Plato during those times in Egypt.
Group C
Although most of the relevant tissues and endocrine glands had been identified by early anatomists, a more humoral approach to understanding biological function and disease was favoured by the ancient Greek and Roman thinkers such as Aristotle, Hippocrates, Lucretius, Celsus, and Galen, according to Freeman et al., and these theories held sway until the advent of germ theory, physiology, and organ basis of pathology in the 19th century.
Group D
Descartes refused to accept the authority of previous philosophers. He frequently set his views apart from those of his predecessors. In the opening section of the "Passions of the Soul", an early modern treatise on emotions, Descartes goes so far as to assert that he will write on this topic "as if no one had written on these matters before". His best known philosophical statement is "I think, therefore I am" (; ), found in "Discourse on the Method" (1637; written in French and Latin) and "Principles of Philosophy" (1644; written in Latin).
Early Islamic philosophy began in the 2nd century AH of the Islamic calendar (early 9th century CE) and lasted until the 6th century AH (late 12th century CE). The period is known as the Golden Age of Islam, and the achievements of this period had a crucial influence on the development of modern philosophy and science in the Western world; for Renaissance Europe, the influence represented from the Islamic Golden Age was “one of the largest technology transfers in world history”. This period began with al-Kindi in the 9th century and ended with Averroes (Ibn Rushd) at the end of 12th century. The death of Averroes effectively marked the end of a particular discipline of Islamic philosophy usually called the Peripatetic Arabic School, and philosophical activity declined significantly in Western Islamic countries such as Islamic Iberia and North Africa.
Derrida, the father of deconstruction, practiced philosophy as a form of textual criticism. He criticized Western philosophy as privileging the concept of presence and "logos", as opposed to absence and markings or writings.
Kant developed his moral philosophy in three works: "Groundwork of the Metaphysic of Morals" (1785), "Critique of Practical Reason" (1788), and "Metaphysics of Morals" (1797).
Between 1509 and 1511, Raphael also completed another work on the wall opposite the "Disputa". This third painting, entitled "The School of Athens", represents the degrees of knowledge or the truth acquired through reason. The fresco's position as well as the philosophers' walk in direction of the Holy Sacrament on the opposite wall suggested the interpretation of the whole room as the movement from the classical philosophy to the true religion and from the pre-Christian world to Christianity. It was meant to reside over the philosophical section of Pope Julius II's library. It is perhaps Raphael's most famous fresco.
Thales used geometry to solve problems such as calculating the height of pyramids and the distance of ships from the shore. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. As a result, he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. Pythagoras established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The Pythagoreans are credited with the first proof of the Pythagorean theorem, though the statement of the theorem has a long history, and with the proof of the existence of irrational numbers. Although he was preceded by the Babylonians and the Chinese, the Neopythagorean mathematician Nicomachus (60–120 AD) provided one of the earliest Greco-Roman multiplication tables, whereas the oldest extant Greek multiplication table is found on a wax tablet dated to the 1st century AD (now found in the British Museum). The association of the Neopythagoreans with the Western invention of the multiplication table is evident in its later Medieval name: the "mensa Pythagorica".
René Descartes, with "je pense donc je suis" or "cogito ergo sum" or "I think, therefore I am", argued that "the self" is something that we can know exists with epistemological certainty. Descartes argued further that this knowledge could lead to a proof of the certainty of the existence of God, using the ontological argument that had been formulated first by Anselm of Canterbury.
He left a very rich corpus of philosophical and theological works that reveals influence from the works of Ibn Sīnā, Abu'l-Barakāt al-Baghdādī and al-Ghazali. Two of his works titled "Mabāhith al-mashriqiyya fī ‘ilm al-ilāhiyyāt wa-'l-tabi‘iyyāt" ("Eastern Studies in Metaphysics and Physics") and "al-Matālib al-‘Aliya" ("The Higher Issues") are usually regarded as his most important philosophical works.
Aristotle of Stagira, the most important disciple of Plato, shared with his teacher the title of the greatest philosopher of antiquity. But while Plato had sought to elucidate and explain things from the supra-sensual standpoint of the forms, his pupil preferred to start from the facts given us by experience. Except from these three most significant Greek philosophers other known schools of Greek philosophy from other founders during ancient times were Stoicism, Epicureanism, Skepticism and Neoplatonism.
During the 1930s, Georges Florovsky undertook extensive researches in European libraries and wrote his most important works in the area of patristics as well as his magnum opus, "Ways of Russian Theology". In this massive work, he questioned the Western influences of scholasticism, pietism, and idealism on Russian theology and called for a re-evaluation of Russian theology in the light of patristic writings. One of his most prominent critics was Nikolai Berdyaev, the religious philosopher and social critic.
Recent attempts to incorporate Western philosophy into Eastern thought include the Kyoto School of philosophers, who combined the phenomenology of Husserl with the insights of Zen Buddhism. Watsuji Tetsurô, a 20th-century Japanese philosopher attempted to combine the works of Søren Kierkegaard, Nietzsche, and Heidegger with Eastern philosophies. Some have claimed that there is also a definite eastern element within Heidegger's philosophy. For the most part this is not made explicit within Heidegger's philosophy, apart from in the dialogue between a Japanese and inquirer. Heidegger did spend time attempting to translate the Tao Te Ching into German, working with his Chinese student Paul Hsaio. It has also been claimed that much of Heidegger's later philosophy, particularly the sacredness of Being, bears a distinct similarity to Taoist ideas. There are clear parallels between Heidegger and the work of Kyoto School, and ultimately, it may be read that Heidegger's philosophy is an attempt to 'turn eastwards' in response to the crisis in Western civilization. However, this is only an interpretation.
