Literae Humaniores Literae Humaniores is the name given to an undergraduate course focused on Classics (Ancient Rome, Ancient Greece, Latin, ancient Greek and philosophy) at the University of Oxford and some other universities. The Latin name means literally "more humane literature", and was in contrast to the other main field of study when the university began, i.e. res divinae, aka theology. Lit. Hum. is concerned with human learning, and Lit. Div. with learning that came from God. In its early days, it encompassed mathematics and natural sciences as well. Lit. The University of Oxford's classics course, also known as "Greats", is divided into two parts, lasting five terms and seven terms respectively, the whole lasting four years in total, which is one year more than most arts degrees at Oxford and other English universities. The course of studies leads to a Bachelor of Arts (B.A.) degree. Mods The Mods course runs for the first five terms of the course. Greats In 2004 the full Lit.
Neuroanatomy Anatomy of the human brain. Neuroanatomy is the study of the anatomy and stereotyped organization of nervous systems. In contrast to animals with radial symmetry, whose nervous system consists of a distributed network of cells, animals with bilateral symmetry have segregated, defined nervous systems, and thus we can make much more precise statements about their neuroanatomy. In vertebrates, the nervous system is segregated into the internal structure of the brain and spinal cord (together called the central nervous system, or CNS) and the routes of the nerves that connect to the rest of the body (known as the peripheral nervous system, or PNS). The delineation of distinct structures and regions of the nervous system has been critical in investigating how it works. For information about the composition of animal nervous systems, see nervous system. History Composition At the tissue level, the nervous system is composed of neurons, glial cells, and extracellular matrix.
Ocean An ocean (from Ancient Greek Ὠκεανός, transc. Okeanós, the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which occupies two-thirds of the planet's surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern, and Arctic Oceans. The word sea is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land. Earth's global ocean Global divisions Various ways to divide the World Ocean The major oceanic divisions are defined in part by the continents, various archipelagos, and other criteria. Physical properties The bluish color of water is a composite of several contributing agents. Zones with depth The major oceanic divisions Exploration Climate Biology
Isaiah Berlin Sir Isaiah Berlin OM CBE FBA (6 June 1909 – 5 November 1997) was a Russian-British social and political theorist, philosopher and historian of ideas. He was an essayist, conversationalist, raconteur, and lecturer. In its obituary of the scholar, the Independent stated that "Isaiah Berlin was often described, especially in his old age, by means of superlatives: the world's greatest talker, the century's most inspired reader, one of the finest minds of our time [...] there is no doubt that he showed in more than one direction the unexpectedly large possibilities open to us at the top end of the range of human potential". In 1932, at the age of 23, Berlin was elected to a prize fellowship at All Souls College, Oxford. He translated works by Ivan Turgenev from Russian into English and, during the war, worked for the British Diplomatic Service. From 1957 to 1967 he was Chichele Professor of Social and Political Theory at the University of Oxford. Life Thought Gerald C.
Neuroscience Neuroscience is the scientific study of the nervous system. Traditionally, neuroscience has been seen as a branch of biology. However, it is currently an interdisciplinary science that collaborates with other fields such as chemistry, computer science, engineering, linguistics, mathematics, medicine and allied disciplines, philosophy, physics, and psychology. It also exerts influence on other fields, such as neuroeducation and neurolaw. The term neurobiology is usually used interchangeably with the term neuroscience, although the former refers specifically to the biology of the nervous system, whereas the latter refers to the entire science of the nervous system. Because of the increasing number of scientists who study the nervous system, several prominent neuroscience organizations have been formed to provide a forum to all neuroscientists and educators. History The study of the nervous system dates back to ancient Egypt. Modern neuroscience Human nervous system
Surrealist automatism Automatism has taken on many forms: the automatic writing and drawing initially (and still to this day) practiced by surrealists can be compared to similar, or perhaps parallel phenomena, such as the non-idiomatic improvisation. Surrealist automatism is different from mediumistic automatism, from which the term was inspired. Ghosts, spirits or the like are not purported to be the source of surrealist automatic messages. Origins "Pure psychic automatism" was how André Breton defined surrealism, and while the definition has proved capable of significant expansion, automatism remains of prime importance in the movement. In 1919 Breton and Philippe Soupault wrote the first automatic book, Les Champs Magnétiques, while The Automatic Message (1933) was one of Breton's significant theoretical works about automatism. Surautomatism Automatic drawing Automatic drawing was pioneered by André Masson. Contemporary techniques See also  External links
Two Concepts of Liberty "Positive liberty... is a valid universal goal. I do not know why I should have been held to doubt this, or, for that matter, the further proposition, that democratic self-government is a fundamental human need, something valuable in itself, whether or not it clashes with the claims of negative liberty or of any other goal... What I am mainly concerned to establish is that, whatever may be the common ground between them, and whatever is liable to graver distortion, negative and positive liberty are not the same thing." Isaiah Berlin, Five Essays on Liberty: An Introduction "Two Concepts of Liberty" was the inaugural lecture delivered by the liberal philosopher Isaiah Berlin before the University of Oxford on 31 October 1958. It was subsequently published as a 57-page pamphlet by Oxford at the Clarendon Press. "As for Otanes, he wished neither to rule nor to be ruled — the exact opposite of Aristotle's notion of true civic liberty... Summary Positive liberty See also
Gaia hypothesis The study of planetary habitability is partly based upon extrapolation from knowledge of the Earth's conditions, as the Earth is the only planet currently known to harbour life The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that organisms interact with their inorganic surroundings on Earth to form a self-regulating, complex system that contributes to maintaining the conditions for life on the planet. Topics of interest include how the biosphere and the evolution of life forms affect the stability of global temperature, ocean salinity, oxygen in the atmosphere and other environmental variables that affect the habitability of Earth. Introduction Less accepted versions of the hypothesis claim that changes in the biosphere are brought about through the coordination of living organisms and maintain those conditions through homeostasis. In some versions of Gaia philosophy, all lifeforms are considered part of one single living planetary being called Gaia.
Abiogenesis Scientific hypotheses about the origins of life can be divided into a number of categories. Many approaches investigate how self-replicating molecules or their components came into existence. On the assumption that life originated spontaneously on Earth, the Miller–Urey experiment and similar experiments demonstrated that most amino acids, often called "the building blocks of life", can be racemically synthesized in conditions which were intended to be similar to those of the early Earth. Early conditions The Hadean Earth is thought to have had a secondary atmosphere, formed through degassing of the rocks that accumulated from planetesimal impactors. The Hadean environment was highly hazardous to modern life. The earliest life on Earth Between 3.8 and 4.1 Ga, changes in the orbits of the gaseous giant planets may have caused a late heavy bombardment that pockmarked the Moon and the other inner planets (Mercury, Mars, and presumably Earth and Venus).

Counter-Enlightenment The Counter-Enlightenment was a term that some 20th-century commentators have used to describe multiple strains of thought that arose in the late-18th and early-19th centuries in opposition to the 18th-century Enlightenment. The term is usually associated with Isaiah Berlin, who is often credited with coining it, though there are several earlier uses of the term, including one by German philosopher Friedrich Nietzsche, who wrote of Gegenaufklärung at the end of the 19th century. The first known use of the term in English was in 1908, but Berlin may have re-invented it. Berlin published widely about the Enlightenment and its enemies and did much to popularise the concept of a Counter-Enlightenment movement that he characterised as relativist, anti-rationalist, vitalist, and organic, and which he associated most closely with German Romanticism.

James Lovelock James Ephraim Lovelock, CH, CBE, FRS (born 26 July 1919) is an independent scientist, environmentalist and futurist who lives in Dorset, England. He is best known for proposing the Gaia hypothesis, which postulates that the biosphere is a self-regulating entity with the capacity to keep our planet healthy by controlling the interconnections of the chemical and physical environment. Biography Career James Lovelock around 1960 A lifelong inventor, Lovelock has created and developed many scientific instruments, some of which were designed for NASA in its program of planetary exploration. In early 1961, Lovelock was engaged by NASA to develop sensitive instruments for the analysis of extraterrestrial atmospheres and planetary surfaces. Lovelock was elected a Fellow of the Royal Society in 1974. On 8 May 2012, he appeared on the Radio Four series "The Life Scientific", talking to Jim al-Khalili about the Gaia hypothesis.
