Given the question: Information:  - In epistemology, rationalism is the 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".  - A capital market is a financial market in which long-term debt or equity-backed securities are bought and sold. Capital markets are defined as markets in which money is provided for periods longer than a year. Capital markets channel the wealth of savers to those who can put it to long-term productive use, such as companies or governments making long-term investments.  Financial regulators, such as the Bank of England (BoE) or the U.S. Securities and Exchange Commission (SEC), oversee the capital markets in their jurisdictions to protect investors against fraud, among other duties.  - Medicine (British English ; American English ) is the science and practice of the diagnosis, treatment, and prevention of disease. The word "medicine" is derived from Latin "medicus", meaning "a physician". Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.  - The University of Siena (abbreviation: UNISI) in Siena, Tuscany is one of the oldest and first publicly funded universities in Italy. Originally called "Studium Senese", the institution was founded in 1240. It had around 20,000 students in 2006, nearly half of Siena's total population of around 54,000. Today, the University of Siena is best known for its Schools of Law and Medicine.  - Latium is the region of central western Italy in which the city of Rome was founded and grew to be the capital city of the Roman Empire. Latium was originally a small triangle of fertile, volcanic soil on which resided the tribe of the Latins or Latians. It was located on the left bank (east and south) of the Tiber river, extending northward to the Anio river (a left-bank tributary of the Tiber) and southeastward to the Pomptina Palus (Pontine Marshes, now the Pontine Fields) as far south as the Circeian promontory. The right bank of the Tiber was occupied by the Etruscan city of Veii, and the other borders were occupied by Italic tribes. Subsequently, Rome defeated Veii and then its Italic neighbors, expanding Latium to the Apennine Mountains in the northeast and to the opposite end of the marsh in the southeast. The modern descendant, the Italian "Regione" of Lazio, also called "Latium" in Latin, and occasionally in modern English, is somewhat larger still, but not as much as double the original Latium.  - Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.   - Marxism is a method of socioeconomic analysis that analyzes class relations and societal conflict using a materialist interpretation of historical development and a dialectical view of social transformation. It originates from the mid-to-late 19th century works of German philosophers Karl Marx and Friedrich Engels.  - Kantian ethics refers to a deontological ethical theory ascribed to the German philosopher Immanuel Kant. The theory, developed as a result of Enlightenment rationalism, is based on the view that the only intrinsically good thing is a good will; an action can only be good if its maximthe principle behind itis duty to the moral law. Central to Kant's construction of the moral law is the categorical imperative, which acts on all people, regardless of their interests or desires. Kant formulated the categorical imperative in various ways. His principle of universalizability requires that, for an action to be permissible, it must be possible to apply it to all people without a contradiction occurring. His formulation of humanity as an end in itself requires that humans are never treated merely as a means to an end, but always also as ends in themselves. The formulation of autonomy concludes that rational agents are bound to the moral law by their own will, while Kant's concept of the Kingdom of Ends requires that people act as if the principles of their actions establish a law for a hypothetical kingdom. Kant also distinguished between perfect and imperfect duties. A perfect duty, such as the duty not to lie, always holds true; an imperfect duty, such as the duty to give to charity, can be made flexible and applied in particular time and place.  - Vatican City , officially Vatican City State or the State of Vatican City, is a walled enclave within the city of Rome. With an area of approximately 44 hectares (110 acres), and a population of 842, it is the smallest State in the world by both area and population, but formally it is not sovereign, sovereignty being held by the Holy See, the only entity of public international law that has diplomatic relations with almost every country in the world.  - Friedrich Engels (or  28 November 1820  5 August 1895) was a German philosopher, social scientist, journalist, and businessman. He founded Marxist theory together with Karl Marx. In 1845, he published "The Condition of the Working Class in England", based on personal observations and research in Manchester.  - Karl Marx (5 May 1818  14 March 1883) was a German-born scientist, philosopher, economist, sociologist, journalist, and revolutionary socialist. Born in Trier to a middle-class family, he later studied political economy and Hegelian philosophy. As an adult, Marx became stateless and spent much of his life in London, England, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and published various works, the most well-known being the 1848 pamphlet "The Communist Manifesto". His work has since influenced subsequent intellectual, economic, and political history.  - Capitalism is an economic system based on private ownership of the means of production and their operation for profit. Characteristics central to capitalism include private property, capital accumulation, wage labor, voluntary exchange, a price system, and competitive markets. In a capitalist market economy, decision-making and investment is determined by the owners of the factors of production in financial and capital markets, and prices and the distribution of goods are mainly determined by competition in the market.  - Economic determinism is a theory that economic relationships (such as being an owner or capitalist, or being a worker or proletarian) are the foundation upon which all other social and political arrangements in society are based. The theory stresses that societies are divided into competing economic classes whose relative political power is determined by the nature of the economic system. In the version associated with Karl Marx, the emphasis is on the proletariat who are considered to be locked in a class struggle with the capitalist class, which will eventually end with the revolutionary overthrow of the capitalist system and the gradual development of socialism. Marxist thinkers have dismissed plain and unilateral economic determinism as a form of "vulgar Marxism", or "economism", nowhere included in Marx's works.  - Economism is reduction of all social facts to economic dimensions. The term is often used to criticize economics as an ideology, in which supply and demand are the only important factors in decisions, and outstrip or permit ignoring all other factors. It is believed to be a side effect of neoclassical economics and blind faith in an "invisible hand" or "laissez-faire" means of making decisions, extended far beyond controlled and regulated markets, and used to make political and military decisions. Conventional ethics would play no role in decisions under pure economism, except insofar as supply would be withheld, demand curtailed, by moral choices of individuals. Thus, critics of economism insist on political and other cultural dimensions in society.  - Law is a system of rules that are created and enforced through social or governmental institutions to regulate behavior. State-enforced laws can be made by a collective legislature or by a single legislator, resulting in statutes, by the executive through decrees and regulations, or established by judges through precedent, normally in common law jurisdictions. Private individuals can create legally binding contracts, including arbitration agreements that may elect to accept alternative arbitration to the normal court process. The formation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and serves as a mediator of relations between people.  - Italy, officially the Italian Republic, is a unitary parliamentary republic in Europe. Located in the heart of the Mediterranean Sea, Italy shares open land borders with France, Switzerland, Austria, Slovenia, San Marino and Vatican City. Italy covers an area of and has a largely temperate seasonal climate and Mediterranean climate; due to its shape, it is often referred to in Italy as "lo Stivale" (the Boot). With 61 million inhabitants, it is the fourth most populous EU member state.  - Determinism is the philosophical position that for every event there exist conditions that could cause no other event. "There are many determinisms, depending on what pre-conditions are considered to be determinative of an event or action." Deterministic theories throughout the history of philosophy have sprung from diverse and sometimes overlapping motives and considerations. Some forms of determinism can be empirically tested with ideas from physics and the philosophy of physics. The opposite of determinism is some kind of indeterminism (otherwise called "nondeterminism"). Determinism is often contrasted with free will.  - Competition is, in general, a contest or rivalry between two or more organisms, animals, individuals, economic groups or social groups, etc., for territory, a niche, for resources, goods, for mates, for prestige, recognition, for awards, for group or social status, or for leadership and profit. It arises whenever at least two parties strive for a goal which cannot be shared, where one's gain is the other's loss (a zero-sum game).  - The concept of universalizability was set out by the 18th-century German philosopher Immanuel Kant as part of his work "Groundwork of the Metaphysic of Morals". It is part of the first formulation of his categorical imperative, which states that the only morally acceptable maxims of our actions are those that could rationally be willed to be universal law.   - A market economy is an economic system where decisions regarding investment, production, and distribution are based on the interplay of supply and demand, which determines the prices of goods and services. The major defining characteristic of a market economy is that investment decisions, or the allocation of producer good, are primarily made through capital and financial markets. This is contrasted with a planned economy, where investment and production decisions are embodied in an integrated plan of production established by a state or other organizational body that controls the factors of production.  - A revolution (from the Latin "revolutio", "a turn around") is a fundamental change in political power or organizational structures that takes place in a relatively short period of time when the population rises up in revolt against the current authorities. Aristotle described two types of political revolution: Revolutions have occurred through human history and vary widely in terms of methods, duration, and motivating ideology. Their results include major changes in culture, economy, and socio-political institutions.  - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency.  - Ernesto Screpanti ( born 1948 , Rome ) is a professor of Political Economy at the University of Siena .
