Road to Serfdom free essay sample

Hayek has written one of the most important books of our generation. It restates for our time the issue between liberty and authority. It is an arresting call to all well-intentioned planners and socialists, to all those who are sincere democrats and liberals at heart, to stop, look and listen. ’ The author is an internationally known economist. An Austrian by birth, he was director of the Austrian Institute for Economic Research and lecturer in economics at the University of Vienna during the years of the rise of fascism in Central Europe.He has lived in England since 1931 when he became Professor of Economic Science at the University of London, and is now a British citizen. Professor Hayek, with great power and rigour of reasoning, sounds a grim warning to Americans and Britons who look to the government to provide the way out of all our economic dif? culties. He demonstrates that fascism and what the Germans correctly call National Socialism are the inevitable results of the increasing growth of state control and state power, of national ‘planning’ and of socialism.

Toward a better world To build a better world, we must have the courage to make a new start. We must clear away the obstacles with which human folly has recently encumbered our path and release the creative energy of individuals. We must create conditions favourable to progress rather than ‘planning progress’. It is not those who cry for more ‘planning’ who show the necessary courage, nor those who preach a ‘New Order’, which is no more than a continuation of the tendencies of the past 40 years, and who can think of nothing better than to imitate Hitler.

Investigation the Importance of Surface Area to Volume Ratio

Investigation the Importance of Surface Area to Volume Ratio BackgroundCells rely on the diffusion process to gain nutrients and to dispel waste. Because of this, the surface area to volume ratio of cells is very important. As a object becomes smaller, its surface area to volume ratio becomes greater allowing fast diffusion for cells. Though as a object becomes larger, it's surface area to volume ratio becomes smaller and diffusion would no longer be effective for cells as the process would take too long. This is why there is a limit to the size of cells.Research QuestionHow does the surface area to volume ratio effect the time it takes for a object to diffuse?HypothesisThe higher the surface area to volume ratio is, the faster the agar jelly will become clear.VariablesFor this experiment, the independent variable was the surface area to volume ratio of the cubes while the dependent variable was the time it took for the cube to become transparent.Image d'un dodà ©caà ¨dreThe controlled variables were the type and concentration of the acid, t he indicator (phenolphthalein), the process of how acid was added to the beaker, the use of the stopwatch as well as how much of the cubes were covered with acid.MaterialsAgar jelly containing:- 0.1 M NaOH- Phenolphthalein0.1 M H2SO4100 ml or 250 ml beakerCeramic tilePlastic spoonKnifeGloveStopwatchMethodOnce all materials were gathered, the glove was put on and a 2 cm x 2 cm x 2 cm, 1 cm x 1 cm x 1 cm or 0.5 cm x 0.5 cm x 0.5 cm cube was cut with the knife of the ceramic tile.

Countries Analysis - Assignment Example SOUTH AFRICA LABOUR ISSUES Labor force in South Africa has increased since the days of Apartheid. During Apartheid, most of the Blacks were working in the informal sector and mostly provided unskilled labor. In 1994 and 1995, officials revised employment statistics to join into national accounts employment in the former black homelands which were home to almost one-half of the black South African population subject to the revisions, in mid 1995, the government estimated the national work force to 14.3 million people.1 Section 23 of the Constitution of South Africa2 provides for labor relations that everyone has the right to fair labor practices, right to join a trade union and the right to engage in collective bargaining. In 1997, the country3 adopted a new constitution which set out the regulations and basic conditions of employment and the labor laws were to comply with the Republic. The Act applies to all employees save for the members of the National Defense Force, the National I ntelligence Agency, the Secret Service and unpaid volunteers. Section 7 of the Act gives the proviso for regulation of working times. It goes ahead to provide for the allowed rest period to include a rest period of at least 12 hours between ending and recommencing works daily. WAGES An employee must provide written particulars of employment before commencing employment which include place of work; designation of job; the rate payable for overtime and the employee wages. An employer has a duty to pay an employee remuneration that is paid in form of money, the payment has to be calculated by reference to the several hours the employee works, that is 45 hours a week, or 9 hours a day. Notice of termination has to be given to the employee some months or days before an employee is dismissed, this is provided for in the Act. The state enacted Labor Relations Acti which has undergone numerous amendments to change the law governing labor relations and, to give effect to section 27 of the Co nstitution. The Act regulates the rights of the organization; it regulates the rights of the trade unions; it promotes and facilitates collective bargaining at the workplace and at the sector level. The Labor Act also provides for the legal effect of collective agreements, Disputes about collective agreements, Agency shop agreements, Closed shop agreements, Establishment of bargaining councils, Powers and functions of bargaining council, Registration of bargaining councils and the Constitution of bargaining council. LABOR AND POLITICS South African Industrial development had relied on an abundance of low-wage labor for centuries in order to ensure profits,4 but as time went by, economic and social problems associated with implementing apartheid emerged. The development of new technologies during the 1960s and 1970s made most industries to increase their capital stock so that they could invest in machinery and employ a few skilled technicians rather than adopt a labor intensive metho d that would need training and managing a large work force. The trend towards capital-intensive operations led to a lower labor costs and increased productivity. As a result, there was an increased rate of unemployment and poverty which fueled resentment and this made the government to raise the costs of preserving apartheid. Congress of South African Trade Unions (COSATU) was establishment in 1985 by 1990ii more than

Women and Mysticism Essay Example | Topics and Well Written Essays - 500 words

Women and Mysticism - Essay Example Sometimes death is easier than life and possession is easier than death. No matter what your religion, the teachings for that religion refer to demons. These demons are able to possess those that lack strength and are vulnerable to that possession (Bengtsson &Saveman, 2). Women who have been abused and beaten especially by an intimate partner are vulnerable and lack the strength to protect themselves, thus the possession. This is not an effort to show power in a way that is acceptable, this is a direct result of the pain in their lives because of their powerlessness. Distress of the proportions that these women experience bring depression, as well as post-traumatic stress disorder (ptsd) (Goodman, Smyth, Borges, 1). Goodman states that the combination of violence and poverty lead to stress, powerlessness, social isolation, ptsd, depression and other emotional problems. It is not hard to put this damage into perspective when demonization or possession occurs. Who can know whether the demonization they then feel is real or not real. To the victim it is real just like spiders on the wall are very real to the psychotic patient (Goodman, et.al., 2). The Bourguignon paper (559) argues that possession normally affects women in such a way as to allow them to assume a powerful presence or to somehow get what they want.

Is closure of the high street businesses a key factor in the drop of Dissertation

Is closure of the high street businesses a key factor in the drop of Yell's share price - Dissertation Example Its lending operations were limited to the large corporations that could issue bonds to secure loans. When some of the money supply reached those big businesses, the owners and management utilized additional funds to similarly strengthen their balance sheets. In a survey about the SME Access to Finance conducted by the Scottish Government Chief Economic Adviser (2011, p.2), the importance of SMEs was emphasized. They made up 99% of all businesses in Scotland. â€Å"The results showed that the demand for finance (working capital) had increased but that approval rates for applications had fallen. Many firms also perceived the costs of credit to have risen†¦(p.2).† And the â€Å"Overall lending to Scottish SMEs in 2010 is lower than in 2009, reflecting a combination of weak demand and constraints in supply of lending (p.4)†. In another survey by Dr. Fraser, Stuart (2009, p.5), 2,500 SMEs were surveyed in UK. It was discovered that SMEs in UK utilize credit cards (55.3 % of SMEs from 2001-2004 and 54.4 % of SMEs in 2005-2008). Their other sources of financing were as follows: a. Invoice Financing – â€Å"3 % of SMEs in 2001-04 to 2.2 % in 2005-08† (p.5) b. Equity Finance – 3 % c. Credit from Suppliers – 33 % d. Loans from Friends – â€Å"5.6% in 2001-4 to 7.0% in 2005-08† (p.5) e. ... In the results of survey, it was discovered that 62 % had to resort to self-finance or savings to fund a business. Only 26 % borrowed from banks. (p. 19) Following are the charts showing low consumer spending, low consumer confidence, and high unemployment compared to the time before the recession. All are relevant because SMEs could not do well as a result of a poor economic climate. Yell will also feel the crunch because its customers are SMEs. (Source: Oxford Economics: UK Forecast in Detail 2011, p. 63) (Source: Oxford Economics: UK Forecast in Detail 2011, p. 62) ( Source: Bank of England Inflation Report 2011) Note that Velocity of Circulation refers to the time it takes for the banks to make funds available to the public, including SMEs, large corporations, and private individuals. Objectives: 1. To determine why the Share Price of Yell Group PLC has been declining since 2010 up to the present; 2.

Hazards In Sewage Treatment Plants Biology Essay

Hazards In Sewage Treatment Plants Biology Essay Wastewater consists of a mixture of domestic sewage which includes waste from sinks, household toilets, showers, washing machines. It also consists of industrial effluent, occasional run-off of surface water and ground water which has infiltrated into the sewers. 99.99% of wastewater consists of water, and 0.01 % of it comprises of dissolved or suspended solid matter (www.fairfield-city.org/wastewater.cfm Date Accessed 14.02.13) 2.1 Wastewater Biology Untreated sewage may contain a number of disease causing organisms including bacteria, viruses, fungus, worms and protozoa (McCunney, 1986; Weldon et al, 2000; Schlosser et al, 1999). Airborne bacteria concentrations are usually very high where sewage is agitated, such as near incoming wastewater inlets and sludge treatment areas (Laitinen et al, 1994). Compare to other areas of a WWTP, a few airborne bacteria have also been found in clean areas such as control rooms (Laitinen et al, 1994). The major route of exposure to these microorganisms is the foecal-oral route (McCunney, 1986). This commonly occurs during eating, drinking, smoking or by touching the face with contaminated hands or gloves (HSE, 1998). Inhalation of aerosols containing microorganisms is not so common. Nevertheless it is an essential method of entry. Skin absorption is less frequent since pathogens only enter skin damaged by cuts, burns, blisters, or puncture wounds (Laitinen et al 1994; McCunney, 1986). The mucous membranes such as in the eyes and nose may also provide a pathway of entry for certain disease causing microorganisms. 2.2 Hazards in sewage treatment plants 2.2.1 Biological Hazards in wastewater Diseases are caused by infectious agents such as bacteria, viruses, protozoa, helminths and fungi which are present in the raw domestic wastewater mainly from human origin and in agricultural wastes. Diseases are also caused by contact with the toxins released by the infectious organisms, by insects or rodents thriving in the sludge drying beds (ILO Encyclopedia of Occupational Health and Safety, 1983). The following infectious agents can be found in raw wastewater: Table 2.1: The biological organisms in wastewater Organism Signs Symptoms Bacteria Salmonella Nausea, headache, diarrhea and vomiting; almost always with a fever. Tetanus (lockjaw) Muscular stiffness in jaw, neck. Sweating, fever, difficulty swallowing. Shigella Cramps, diarrhea, fever, bloody stool, nausea, vomiting. Leptospirosis (Weils Disease) Intestinal problems, liver and kidney disease, jaundice. E. coli Diarrhea, vomiting, little or no fever, blood often seen in stool. Tulareisis Chills, fever, swollen lymph nodes, stomach pain, diarrhea, vomiting. Yersinia Diarrhea, fever, abdominal pain that resembles appendicitis. Viruses Hepatitis A Fever, abdominal pain, nausea, jaundice, dark-colored urine. Hepatitis B Nausea, vomiting, loss of appetite, jaundice, joint pain. Hepatitis C Develops slowly, loss of appetite, stomach pain, nausea and vomiting. Jaundice is less common. HIV Destroys immune system, prone to opportunistic infections. Polio Fever, headache, nausea, muscle pain and stiffness, paralysis. Parasites Entameoebahistolytica (amebiasis) Mild nausea, loose stool, abdominal tenderness. In severe cases can spread throughout the body and attack other organs, especially the liver. Giardia lamblia Cramps, weight loss, loose/greasy stool, bloating. Fever is rare. Sources: AFSCME; Utah Dept. of Health. 2.2.2 Virus 2.2.2.1 Hepatitis A A study was carried out to determine whether or not occupational exposure to sewage is associated with a higher seroprevalence of hepatitis A virus. In order to carry out the study about 600 sewage workers in Singapore were tested. The study showed that sewage workers had an increased occupational risk of acquiring HAV infection and should be protected by active immunisation (B. H. Heng, K. T. Goh, S. Doraisingham, and G. H. Quek, 1994). 2.2.3 Bacteria 2.2.3.1 Helicobacter pylori Several studies have shown that there was an increased risk for gastric cancer among sewage workers. During the last decade, the bacterium Helicobacter pylori has appeared as one important risk factor for gastric cancer and is now considered a class I carcinogen by the International Agency for Research on Cancer (Rajnarayan R. Tiwari, 2008). 2.2.3.2 Legionella Legionella pneumophiliais usually spread by water aerosols caused either pneumonia or a no pneumonic disease (Pontiac fever). An investigation on American sewage workers found that there was no increased risk of infection with L pneumophilia. But recently some cases of Pontiac fever have been reported in workers exposed to aerosols from a sewage plant in the food industry treating only organic industrial waste. L pneumophilia, similar to that present in the infected workers was cultured from the sludge (Gregersen P, Grunnet K, Uldum SA, Andersen BH, Madsen H. 1999). 2.2.4 Parasites There has been a significant positive association between the finding of protozoa in faeces from sewage workers and the duration of exposure to sewage, (Knobloch J,Bialek R,Hagemann J. Intestinaler Protozoenbefall durchberufsbedingten Abwasserkontakt,1983). It has been reported that the prevalence of infestation with intestinal parasites was decreased by adopting good hygienic practices (Schlosser, O., et al, 1999). An increased risk for giardiasis has been reported among workers in France and Germany (Schlosser et al, 1999; Knobloch J, Bialek R, Hagemann J. Intestinalerb Protozoenbefallb durchberufsbedingtenb Abwasserkontakt,1983; Doby JM, Duval JM, Beaucournu JC.Amibiase, 1980; Clark CS, Linnemann CC, Clark JG, Gartside PS.1984; Sullivan R, LinnemannJr CC, Clark CS, Walzer PD.1987).An increased incidence of Entamoebahistiolytica has been reported in sewage exposed workers in France, but not in Germany (Bialek R, Hagemann J. Intestinaler Protozoenbefalldurchberufsbedingten Abwasserk ontakt. Dtsch Med Wochenschr, 1983; Doby JM, Duval JM, Beaucournu JC.Amibiase, 1980). 2.3 Chemical Hazard Wastewater contains a great amount of industrial contaminants which may harm those people who come into contact with sewage. According to the Pennsylvania DEP, methane and carbon dioxide were the most common chemical byproducts of wastewater. If found in a small enclosed space with a quantity of sewage, these gases could crowd out oxygen and asphyxiate anyone trapped in the area (Nellie J.Brown, 1997). Sewage workers were also exposed to gases such as hydrogen disulfide, methane, ammonia and carbon monoxide. Watt and his colleagues carried out a study on 26 sewer workers exposed to smell and it was found that 53.8% developed sub-acute symptoms including sore throat, cough, chest tightness, breathlessness, thirst, sweating and irritability. Severity of symptoms seemed to be dose related (Watt MM, Watt SJ, Seaton A. 1997). 2.4 Physical Hazard Physical hazards were caused due to exposures to excessive noise levels from mechanical equipment, UV radiation and adverse weather such as low or high temperature, and rain. (ILO Encyclopedia of Occupational Health and Safety, 1998) 2.5 Ergonomic Factors Musculoskeletal injuries were caused by over exertion during handling heavy loads, such as containers of chemicals, or by awkward working postures including frequent bending (ILO Encyclopedia of Occupational Health and Safety, 1983). Sewage workers have reported osteoarthritic problems and intervertebral disc herniation which are the common spinal disorders (ILO Encyclopedia of Occupational Health and Safety, 1970). An investigation was carried out by Friedrich on 255 sewage workers to determine the occurrence of spinal troubles (i.e., neck, upper back and lower back pain [LBP]). He reported that the 12-month prevalence rates of neck, upper back and LBP were 52.4%, 54.8% and 72.8%, respectively. He concluded that the occurrence of spinal troubles and work disability due to LBP increased with age, weekly duration of stooping, lifting and higher abnormal illness-behavior scores (Friedrich M, Cermak T, Heiller I, 2000). 2.6 Psychosocial and organizational factors Discomfort and psychological problems were related to prolonged wearing of protective clothing, the bad smells of the wastes, the feeling of working with soiled liquids in a dirty and not too respectable occupation, and to the worries caused by awareness of the dangers of the workplace (ILO Encyclopedia of Occupational Health and Safety, 1983). 2.7 Accidental hazards Accidental hazards which occurred in wastewater treatment plants included the followings: Slips and falls on floors made slippery by water, aqueous solutions or solvents. Falls into ponds, pits, clarifiers or tanks causing injuries or drowning. Hazards related to entry into confined spaces. Suffocation can occur due to oxygen shortage, poisoning such as hydrogen sulfide. Burns, by steam or hot vapors, by splashes of hot plating baths, solvent sand other liquids, by contact with hot surfaces (e.g., annealing ovens), Electric shock caused by contact with faulty electrical equipment and cables. Cuts and pricks by sharp tools sharp edges. Injuries especially of eyes caused by flying particles, in particular from rotating brush cleaning or wheel grinding. Fire and explosions due to the formation and release of flammable gases such as methane, hydrogen during processing. Strong chemical reactions caused by uncontrolled mixing of chemicals For example when mixing water with concentrated sulfuric acid during the preparation of reagents for wastewater treatment. Acute poisoning caused by various chemicals such as gaseous chlorine present in the wastes which is used as reagents, or released during the treatment. Acute intoxication caused if mistakenly drank untreated wastewater. Poisoning by phosgene, this may be formed if a worker smokes in the presence of chlorinated-solvent vapors, or if welding or other flames or arcs are used. Chemical burns by corrosive liquids. Damage to eyes by splashes of irritating or corrosive liquids (ILO Encyclopedia of Occupational Health and Safety, 1998). At a sewage treatment plant in Homeballe in Kimberley,five men aged between thirty and fifty who were repairing the pipes had lost their lives after drowning in a bay. It was believed that they may have gone unconscious due to the toxic fumes from the sewage and the area that they were in then filled up with water and sewage causing all five men to then drown (Jonckie on November 6th, 2012). 2.8 Health problems of workers at the treatment plant 2.8.1 Effects on skin and mucous membranes among the workers Many sewage workers have reported skin disorders (Lundholm M, Rylander R, 1983; Scarlett-Kranz JM, Babish JG, Strickland D, Lisk DJ, 1987) and inflammation of the eyes (Lundholm M, Rylander R, 1983; Mattsby I, Rylander R., 1978).After an accidental exposure to dust containing sludge, several incinerator workers at a sewage treatment plant in Toronto, Canada were affected by irritant contact dermatitis (Nethercott JR, 1981). 2.8.2 Effects on the nervous system Studies have also revealed that central nervous system symptoms such as headache, unusual tiredness, and concentration difficulties have been found among the sewage workers. In addition, an increased risk for non-specific work related gastrointestinal symptoms was found among the sewage workers (J Thorn, L Beijer, R Rylander, 2002). 2.8.3 Respiratory symptoms Several studies have been done to study the respiratory function of sewage workers. All of them demonstrated that respiratory symptoms such as chronic bronchitis and toxic pneumonitis were common among these workers (J Thorn, L Beijer, R Rylander, 2002). Moreover, abnormal respiratory functions which arose due to exposure to endotoxins and airborne bacteria by way of bio aerosols were also discovered in those sewage workers. Furthermore, Zuskin et al. reported that sewage workers were exposed to different occupational noxious agents, which may lead to the development of chronic lung function changes (Zuskin E, Mustajbegovic J, Schachter EN, 1993). 2.9 Health Safety of workers According to OSHA, the employer should give the worker: Training and education about the hazards present at the wastewater treatment plant. A place onsite with clean water for washing hands A place to wash and clean up after work. The right PPE, such as gloves, goggles, a face shield, water-resistant suit, or respirator, depending on the job type. Clean areas for eating and smoking. Cleaning facilities or services for clothing and equipment. (If clothing is badly soiled, change out of it. Keep equipment clean to limit your exposures to the disease-causing agents (Anon, 2004). 2.9.1 Safety of workers In wastewater treatment plants, engineering controls and work practices are the best ways to protect workers from exposures to disease. When engineering controls are not possible, the use personal protective equipment (PPE) is encouraged (Anon, 2004). 2.9.1.2 Engineering controls Engineering controls remove or reduce the hazard either by initial engineering design specifications or by applying methods such as substitution, isolation or ventilation (Raterman, 2002). 2.9.1.3 Administrative control Administrative controls that minimise employees exposures by scheduling reduce work times in contaminant areas, good work practices and employee training. Appropriate training which includes hazard recognition and work practices specific to the employees job that can help reduce exposures are given (Raterman, 2002). 2.9.1.4 Personal Protective Equipment (PPE) Personal Protective Equipment means any equipment intended to be worn or held by an employee and which protects him against risk to his health or safety. It includes: (a) Any addition or accessory designed to meet that objective; and (b) Clothing affording protection against the weather; (Occupational Safety and Health act, 2005) Workers handling sewage are provided with proper PPE. The following PPE are recommended for workers handing sewage: Goggles: to protect eyes from splashes of human waste or sewage. Protective face mask or splash-proof face shield: to protect nose and mouth from splashes of human waste or sewage. Liquid-repellent coveralls: to keep human waste or sewage off clothing. Waterproof gloves: to prevent exposure to sewage. Rubber boots: to prevent exposure to sewage.(Centers for Disease Control and Prevention, 2002). 2.9.1.5 Training for Workers All workers who handle sewage receive training. The training should include information on basic hygiene practices; use and disposal of personal protective equipment; proper handling of sewage; signs and symptoms of the different types of diseases present; and ways in which diseases can be transmitted. Workers are also advised to immediately seek medical attention if displaying any signs or symptoms such as vomiting, stomach cramps and watery diarrhea (Centers for Disease Control and Prevention, 2002). 2.10 Hygiene Practices 2.10.1 Hygiene Hygiene is the association of human sciences, professions, technologies and disciplines for the purpose of protecting the health of individuals and community from any harmful exposure (Goldner, 2009). The science of hygiene comprises of disciplines, microbiology, parasitology, immunology, toxicology, entomology, pharmacology, environmental health including geography, topography, and engineering, all with a view to limit, inhibit, or block sources and characteristics that deter from normal living. 2.10.2 Hygiene at Work Protecting workers against disease, ill-health or impairment due to chemical, microbiological and physical health hazards, not only during, but after work, has been the traditional goal of occupational hygiene. Prevention of occupational diseases emanating from the workplace due to toxic exposures has been one of the primary roles (Pityn, 2007). A well planned and properly executed sanitation program for the workplace is of great importance for both the workers and the employers as it helps a company to attain better productivity in a safer work place and it ensures good working conditions for the workers. 2.11 Medical surveillance According to Occupational Safety and Health act, health surveillance should be provided to employees who are exposed to potentially hazardous substance. The medical surveillance should be free of charge and should be carried out at intervals of not less than once every 6 months or at shorter intervals as the medical practitioner may advise. (Occupational Safety and Health act 2005). 2.12 The role of Waste Water Management Authority (WMA) The WMA manages the public sewerage system which consists of 515 km of sewer network, 19 treatment plants and 50 pumping stations with the main treatment plants located at St-Martin, Grand-Baie, Baie-du-Tombeau, and Montagne Jacquot. The Wastewater Management Authority (WMA) has been established as a corporate body under the Wastewater Management Authority Act to be responsible for all matters relating to the collection, treatment and disposal of wastewater. It operates as an autonomous organization under the aegis of the Ministry of Renewable Energy and Public Utilities. The WMA thus plays an important role in the protection of the environment and in ensuring the countrys sustainable development by the provision of appropriate water pollution standards, wastewater control systems and management services to the entire population of Mauritius (www.gov.mu Accessed on 16.12.12). 2.13 The purpose of this study The general aim of the present study is to identify the general conditions of workers, the possible communicable and non-communicable disease which may affect the workers, the different types of symptoms experienced by the workers at the workplace, the personal protective equipment provided to the workers and the potential risk that can affect the workplace. In addition, information collected from the survey shall broaden the knowledge of sewage workers in regards to the harmful effects of sewage on health.

Understanding Human Nature: Examples from Philosophy and the Arts :: Philosophy

Understanding Human Nature: Examples from Philosophy and the Arts ABSTRACT: Ours is not the first time philosophers have looked to art for examples to illustrate their arguments. One example would be Kierkegaard, who turned to Mozart's operas in an attempt to expose what he called the aesthetic realm of existence. I hold that if Kierkegaard lived today, he would consider the main character of Nikita Mikhalkov's Dark Eyes (1987) as a prototype of the aesthetic way of existence. In order to support my thesis, I first discuss Kierkegaard's theory of the three spheres of existence. I look especially at what he considers to be the main feature of the aesthetic stage, as well as the figure of Don Giovanni in Mozart's opera. Second, I will look at the character of Romano Podroni in Dark Eyes. Finally, I will point out what makes these two characters prototypes of the aesthetic existence: the inhuman way in which they live the temporal dimension of human existence. 1. Kieregaard's theory of the spheres of existence The question of human existence is the focal point of all Kierkegaard's thought. For Kierkegaard, existing meant becoming more and more individual, but this is not given to all human beings in the same measure, because we may be living in an inauthentic way. The fact that someone belongs to the species homo sapiens does not guarantee that that person leads a human existence. In fact, Kierkegaard seems to think that few people — or at least, a minority of people — genuinely live as human beings. So, what does Kierkegaard mean by living in a fully human way? In his view, existence is above all something that has to be shaped. People must make themselves if they want to be themselves. "A man cannot evade this self-realisation; that would be as impossible as evading one's very self — wich is really the same thing, as the self is the same as self-realisation". (1) The self cannot be itself unless it is creating itself. So, the fact that people have to form themselves means that human existence is a task. (2) Kierkegaard writes of three basic stages in this process of self-realisation: the aesthetic stage, the ethical stage and the religious stage. (3) All human beings are currently at one of this stages, depending on the extent to which they have achieved their life-project. Each stage is a way of seeing life, a way of understanding the world.
