Philosophy: An introduction…

Philosophy & Ethics

While the earliest philosophers sought to understand the earlier universe, it was not long before philosophy turned its attention to humans themselves, and the way we lead our lives. The idea of virtue was central to life in classical society, but difficult to define; concepts of good and evil, happiness, courage and morality became the subjects of debate in the branch of philosophy known as ethics, or moral philosophy.

In trying to ascertain the nature of a virtuous life, philosophers raised the question of what the goal of life should be – what is its ‘purpose’? How should we lead our lives, and to what end? The concept of the ‘good life’, eudemonia, figured largely in Greek philosophy, and embodies not only a virtuous life, but also a happy one. Several different schools of thought emerged as to how this ‘good life’ could be achieved, including the cynics, who believed in harmony with nature, the Epicureans, who believed pleasure to be the greatest good, and the stoics, who believed in acceptance of things beyond our control.

Where ethics and moral philosophy seek to define virtue and what constitutes the ‘good life’, the closely related branch of political philosophy examines the nature of concepts such as justice, and what sought of society can best allow its citizens to lead ‘good’ lives. The problems of how society should be organised and governed were of paramount importance not only to classical Greece, but also in the development of nation-states in China at much the same time, and elsewhere as new civilisations emerged.

As a branch of philosophy, political philosophy deals with ideas of justice, liberty and rights, and the relationship between a state and its citizens. It also examines various forms of government, such as monarchy, aristocracy, oligarchy, tyranny and democracy, and how each affects the rights and freedoms of the individual, as well as examining the relationship in how they exert their authority through the rule of law.

Aesthetics

As the classical Greek philosophers sought to define concepts such as virtue and justice, giving rise to the branches of moral and political philosophy, they also asked the question: ‘What is beauty?’ This is the fundamental question of aesthetics. As a branch of philosophy, aesthetics tries to establish what, if any, objective criteria there are for judging whether something is beautiful, but, in a wider sense also examines all aspects of art – including the very basic question ‘What is art?’

At various times in history, the emphasis of aesthetics has moved from what constitutes art to the religious or socio-political significance of works of art, a general theory of our appreciation of art and how we perceive it, and the process of artistic creativity itself. Philosophical and ethical problems are also raised when considering such matters as the authenticity of a work of art or the sincerity of its creator.

Eastern and Western philosophies

Although the tradition that began in ancient Greece still tends to dominant philosophical discussion in the Western world, philosophy is by no means restricted to that single tradition. Thinkers such as Laozi and Confucius in China also founded their own traditions of philosophy from different starting points, as, arguably, did Buddha in India. For them, and subsequent Eastern philosophers, questions of metaphysics were considered to be adequately explained by religion – hence the Eastern traditions are much more focused on concepts of virtue and the way in which we should lead our lives. In China especially, this moral philosophy was adopted by the ruling dynasties and took on a political dimension.

Eastern and Western philosophies developed very separately until the 19th century, when European philosophers, notably Schopenhauer, began to take an interest in Indian religious and philosophical thought. Elements of Eastern philosophy have subsequently been incorporated into some branches of Western philosophy.

Philosophy vs. religion

Religion and philosophy offered two distinctly different approaches to answering our questions about the world about us – religion through belief, faith and divine revelation, and philosophy through reason and argument – but they often cover much the same ground and are sometimes interrelated. Eastern philosophy developed side by side with religion, and Islam saw no incompatibility between its theology and the philosophy it inherited from the classical world, but the relationship between Western philosophy and Christianity was very often uneasy. Church authorities in the medieval period saw philosophy as a challenge to their dogma, and Christian philosophers risked being branded as heretics for attempting to incorporate Greek philosophical ideas into Christian doctrine. But more than that, philosophy also brought into question issues of belief as opposed to knowledge, faith as opposed to reason – questioning, for example, whether there was any evidence for miracles or even whether the existence of God could be proved.

Philosophy vs. science

Throughout much of the history of philosophy, there was no such thing as science in its modern form: in fact, it was from philosophical enquiry that modern science has evolved. The questions that metaphysics set out to answer about the structure and substance of the universe prompted theories that later became the foundations of ‘natural philosophy’, the precursor of what we now call physics. The process of rational argument, meanwhile, underpins the ‘scientific method’.

Since the 18th century, many of the original questions of metaphysics have been answered by observation, experiment and measurement, and philosophy appeared to be redundant in these areas. Philosophers have since changed their focus to examine science itself. Some, like Hume, challenged the validity of inductive reasoning in science, while others sought to clarify the meaning of terms used by science, opening up a ‘philosophy of science’ that considers areas such as scientific ethics and the way science makes progress.

 

ONE of the features of philosophy that distinguishes it from other ways at looking at the world is that its students are encouraged not to accept the conclusions of their teachers, but to discuss, argue and even disagree. This is exactly what happened in the very first school of philosophy, the Milesian school founded by Thales: his student Anaximander asked if the Earth was supported by water then what supported that? He suggested that the Earth was a drum-shaped cylinder hanging in space, with one of the flat surfaces forming the world we live on. Anaximander, also had a pupil, Anaximenes, who said that the world was self-evidently flat and floated on air. Using the same sort of arguments as Thales, he concluded that the single element from which everything is made is air. Although the conclusions of the Milesian philosophers seem to us hopelessly wrong in the light of later scientific discoveries, the process of reasoning used to reach them – especially argument and counter-argument – still forms the basis for philosophical investigation.

The argument Anaximander used to challenge his teacher’s theory of the Earth floating on water involved an idea that crops up in several strands of philosophy. If the world is supported by a body of water, then what supports the water? And then, what supports that? And so on, ad infinitum. The same pattern can be seen in arguments involving cause and effect: if something causes something else, then what causes that? This apparently unending chain is called infinite regress. Some philosophers saw the existence of infinite regress as proof that the universe is eternal, but many were uncomfortable with the idea and proposed that there must be an original or first cause for everything (an idea that chimes with the modern theory of the Big Bang). For some, the first cause or ‘prime mover’ was an abstract idea akin to pure thought or reason, but, for medieval Christian philosophers especially, it was God: indeed, the idea of a first cause was at the heart of Thomas Aquinas’s cosmological argument for the existence of God.

Heraclitus: everything is in flux

In contrast to the school of philosophy founded by Thales at Miletus, just along the Ionian coast in the city of Ephesus lived a solitary thinker, Heraclitus, who had very different philosophical views. Rather than suggesting a single element from which everything was derived, he suggested an underlying principle – that of change. Heraclitus saw everything as consisting of opposing properties or tendencies, which come to together to make up the substance of the world. The analogy he gave was that the path up a mountain is the same as the path down.

In this theory, known as the ‘unity of opposites’, the tension and contradiction of opposing forces is what creates reality, but is inherently unstable. Therefore, everything is constantly changing: everything is in a state of flux. Just as the water in a river is constantly flowing onwards, but the river itself remains the same, that which we consider to be permanent, unchanging reality consists not of objects, but processes.

Dresden and the Allied bombings of World War II…

70 YEARS ON

Today, the blossoming of Dresden in the east of Germany stands in stark contrast to how the city looked from the ruins of the Allied bombings towards the end of World War II.

British and American bombers dropped 3,900 tonnes of explosives on the Saxony city during four raids on 13th-15th February 1945, killing an estimated 25,000 people and reducing the city to rubble.

The bombing, ordered by Royal Air Force marshal Sir Arthur ‘Bomber’ Harris, was widely criticised because of the indiscriminate and ‘blanket bombing’ which hit civilian areas as well as military targets – killing thousands of innocents.

Over two days and nights in February 1945, 722 heavy bombers of the British Royal Air Force (RAF) and 527 of the United States Army Air Forces (USAAF), turned the city into a sea of flames and rubble.

The resulting firestorm is said to have reached temperatures of over 1,500C (2,700F), destroying over 1,600 acres of the city centre.

The victims – mostly women and children – died in savage firestorms whipped up by the intense heat of 2,400 tons of high explosive and 1,500 tons of incendiary bombs.

It was initially claimed that up to 250,000 civilians lost their lives in the Dresden bombings but an official report released after the war showed the casualty figure was in fact closer to between 22,500 and 25,000.

A police report written shortly after the bombings showed that the city centre firestorm had destroyed almost 12,000 houses, including 640 shops, 18 cinemas, 39 schools, 26 public houses and the city zoo.

The destruction of Dresden has been subjected to much fierce debate in the 70 years since the war. No one has ever been charged over the bombings, but several historians both in Germany and former Allied nations hold the opinion that the bombing was a war crime.

British Prime Minister Winston Churchill, ultimately responsible for the attack, distanced himself from the bombing of Dresden shortly afterwards.

An RAF memo issued to airmen on the night of the attack said:

… ‘Dresden, the seventh largest city in Germany and not much smaller than Manchester is also the largest unbombed built-up area the enemy has got. In the midst of winter with refugees pouring westward and troops to be rested, roofs are at a premium, not only to give shelter to workers, refugees, and troops alike, but to house the administrative services displaced from other areas.

… At one time, and well known for its china, Dresden has developed into an industrial city of first-class importance…. The intentions of the attack are to hit the enemy where he will feel it most, behind an already partially collapsed front… and incidentally to show the Russians when they arrive what Bomber Command can do.’

Bomber Command, which suffered the highest casualty rate of any British unit, losing 55,573 of its 125,000 men, eventually gained a memorial in 2012, but sections of society in Britain were outraged and disgusted with public recognition being given to such attacks. It is the view of many that such a memorial should never have been authorised by the British Government because of the attacks on civilians and on non-strategic targets.

Quantum Leaps: Archimedes…

c. 287 – 212 BC

“Give me a place to stand on, and I will move the earth,” Archimedes is reputed to have declared to the people of Syracuse. The practicalities of an earth-bound life may have denied him that particular pedestal but arranging for his patron King Heiron to move a ship by pushing a small lever was considered only a slightly miraculous feat. With such audacious displays, along with his brilliance as an inventor, mechanical scientist and mathematician, it is no wonder Archimedes was so popular and highly regarded among his contemporaries.

The Mathematician

It was not only his peers, however, who benefited from Archimedes’ work. Many of his achievements are still with us today. First and foremost, Archimedes was an outstanding pure mathematician, “usually considered to be one of the greatest mathematicians of all time,’ according to the Oxford Dictionary of Scientists. He was, for example, the first to deduce that the volume of a sphere was 4πr³ x 3, where r is the radius. Other work in the same area, as outlined in his treatise On the Sphere and Cylinder, led him to deduce that a sphere’s surface area can be worked out by multiplying that of its greatest circle by four: or, similarly, a sphere’s volume is two-thirds that of its circumscribing cylinder. He calculated pi to be approximately 22/7, a figure that was widely used for the next 1500 years.

The Archimedes Principle

Archimedes also discovered the principle that an object immersed in a liquid is buoyed or thrust upwards by a force equal to the weight of the fluid it displaces. The volume of the displaced liquid is the same as the volume of the immersed object. Legend has it that he discovered this when set a challenge by King Heiron to find out whether one of his crowns was made of pure gold or was a fake. While contemplating the problem Archimedes took a bath and noticed that the more he immersed his body in the water, the more the water overflowed from the tub. He realised that if he immersed the crown in a container of water and measured the water that overflowed he would know the volume of the crown. By obtaining a volume of pure gold equivalent to the volume of water displaced by the crown and then weighing both the crown and the gold, he could answer the King’s question. On making this realisation, Archimedes is said to have leapt from his tub and run naked along the street shouting ‘Eureka!’, ‘I have found it!’

Levers and Pulleys

Indeed, it was the practical consequences of Archimedes’ work which mattered more to his contemporaries and for which he became famous.

One such practical demonstration allowed King Heiron to move a ship with a single small lever – which in turn was connected to a series of other levers. Mathematically, he understood the relationship between the lever length, fulcrum position, the weight to be lifted and the force required to move the weight. This meant he could successfully predict outcomes for any number of levers and objects to be lifted.

Likewise he came to understand and explain the principles behind the compound pulley, windless, wedge and screw, as well as finding ways to determine the centre of gravity in objects.

Archimedes goes to war

Perhaps the most important inventions to his peers, however, were the devices created during the Roman siege of Syracuse in the second Punic War. The Romans eventually seized Syracuse, due to neglect of the defences, and Archimedes was killed by a Roman soldier while hard at work on mathematical diagrams. His last words are reputed to have been, ‘Fellow, do not disturb my circles!’

Further achievements

Inventions

. Archimedes’ Screw: a device used to pump water out of ships, and also to irrigate fields.

. Archimedes’ Claw: a huge war machine designed to sink ships by grasping the prow and tipping them over, used in the defence of Syracuse.

. Compound pulley systems: enabled the lifting of enormous weights at a minimal expenditure of energy.

. The method of exhaustion: an integral-like limiting process used to compute the area and volume of two dimensional lamina and three-dimensional solids.

Discoveries

. Archimedes was responsible for the science of hydrostatics, the study of the displacement of bodies in water. He also discovered the principles of static mechanics and pycnometry (the measurement of the volume or density of an object).

. Known as the ‘father of integral calculus’, Archimedes’ reckonings were later used by, among others, Kepler, Fermat, Leibniz and Newton.
