Public reason requires that the moral or political rules that regulate our common life be, in some sense, justifiable or acceptable to all those persons over whom the rules purport to have authority. [1] [2] It is an idea with roots in the work of Thomas Hobbes, Immanuel Kant, and Jean-Jacques Rousseau, and has become increasingly influential in contemporary moral and political philosophy as a result of its development in the work of John Rawls, Jürgen Habermas, and Gerald Gaus, among others.
The phrase "public use of one's reason" (Vernunft in allen Stükken öffentlichen Gebrauch) was used by Immanuel Kant in his 1784 editorial piece responding to the question "What Is Enlightenment?," where he distinguished it from private usage of reason, by which he meant reasoning offered from a specific civic office or post. [3] This Kantian conception was further developed by American philosopher John Rawls to refer to the common reason of all citizens in a pluralist society and identified it as a component of political liberalism. [4] Although Rawls cited the Kantian origin of his concept, his understanding is distinguished by the way he explained how public reason embodies the shared fund of beliefs and reason of those who constitute a democratic polity—those who are concerned with the good of the public and matters of basic justice. [4]
Public reason giving, in the Rawlsian sense, involves justifying a particular position by way of reasons that people of different moral or political backgrounds could accept. Although in his later writings he added what is known as the proviso, meaning that non-public reasons could be given assuming that public reasons would be provided in due course. [5] In order to accomplish this, however, one must overcome what he refers to as the burdens of judgment, which can produce disagreement among reasonable citizens. These burdens include conflicting evidence, giving differing weights to considerations, conceptual indeterminacy, differing experiences and value conflicts. Private reason, by contrast, is the exercise of an individual's reason to the constrained norms and interests of some sub-set of the public as a whole (such as a business, a political party, the military or the family).
Rawls also classified the concept into public reason for "liberal peoples" and public reason for "society of peoples". The former involves public reason of free and equal liberal peoples who debate their mutual relations while the latter involves equal citizens of domestic society debating political issues and justice concerning their government. [6]
Immanuel Kant was a German philosopher and one of the central Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential figures in modern Western philosophy.
Justice, in its broadest sense, is the concept that individuals are to be treated in a manner that is equitable and fair. These individuals are to receive that which they deserve, with the interpretation of what then constitutes "deserving" being impacted upon by numerous fields, with many differing viewpoints and perspectives, including the concepts of moral correctness based on ethics, rationality, law, religion, equity and fairness. The state will sometimes endeavor to increase justice by operating courts and enforcing their rulings.
Political philosophy or political theory is the philosophical study of government, addressing questions about the nature, scope, and legitimacy of public agents and institutions and the relationships between them. Its topics include politics, liberty, justice, property, rights, law, and the enforcement of laws by authority: what they are, if they are needed, what makes a government legitimate, what rights and freedoms it should protect, what form it should take, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever.
In ethics and the social sciences, value theory involves various approaches that examine how, why, and to what degree humans value things and whether the object or subject of valuing is a person, idea, object, or anything else. Within philosophy, it is also known as ethics or axiology.
In moral and political philosophy, the social contract is a theory or model that originated during the Age of Enlightenment and usually, although not always, concerns the legitimacy of the authority of the state over the individual.
John Bordley Rawls was an American moral, legal and political philosopher in the liberal tradition. Rawls received both the Schock Prize for Logic and Philosophy and the National Humanities Medal in 1999. The latter was presented by President Bill Clinton in recognition of how his works "revived the disciplines of political and ethical philosophy with his argument that a society in which the most fortunate help the least fortunate is not only a moral society but a logical one".
In the 19th century, the philosophers of the 18th-century Enlightenment began to have a dramatic effect on subsequent developments in philosophy. In particular, the works of Immanuel Kant gave rise to a new generation of German philosophers and began to see wider recognition internationally. Also, in a reaction to the Enlightenment, a movement called Romanticism began to develop towards the end of the 18th century. Key ideas that sparked changes in philosophy were the fast progress of science, including evolution, most notably postulated by Charles Darwin and Jean-Baptiste Lamarck, and theories regarding what is today called emergent order, such as the free market of Adam Smith within nation states, or the Marxist approach concerning class warfare between the ruling class and the working class developed by Karl Marx and Friedrich Engels. Pressures for egalitarianism, and more rapid change culminated in a period of revolution and turbulence that would see philosophy change as well.
A Theory of Justice is a 1971 work of political philosophy and ethics by the philosopher John Rawls (1921–2002) in which the author attempts to provide a moral theory alternative to utilitarianism and that addresses the problem of distributive justice. The theory uses an updated form of Kantian philosophy and a variant form of conventional social contract theory. Rawls's theory of justice is fully a political theory of justice as opposed to other forms of justice discussed in other disciplines and contexts.
Virtue ethics is an approach to ethics that treats the concept of moral virtue as central. Virtue ethics is usually contrasted with two other major approaches in ethics, consequentialism and deontology, which make the goodness of outcomes of an action (consequentialism) and the concept of moral duty (deontology) central. While virtue ethics does not necessarily deny the importance of goodness of states of affairs or moral duties to ethics, it emphasizes moral virtue, and sometimes other concepts, like eudaimonia, to an extent that other ethical dispositions do not.
In most contexts, the concept of good denotes the conduct that should be preferred when posed with a choice between possible actions. Good is generally considered to be the opposite of evil and is of interest in the study of ethics, morality, philosophy, and religion. The specific meaning and etymology of the term and its associated translations among ancient and contemporary languages show substantial variation in its inflection and meaning, depending on circumstances of place and history, or of philosophical or religious context.
"Answering the Question: What Is Enlightenment?", often referred to simply as "What Is Enlightenment?", is a 1784 essay by the philosopher Immanuel Kant. In the December 1784 publication of the Berlinische Monatsschrift, edited by Friedrich Gedike and Johann Erich Biester, Kant replied to the question posed a year earlier by the Reverend Johann Friedrich Zöllner, who was also an official in the Prussian government. Zöllner's question was addressed to a broad intellectual public community, in reply to Biester's essay entitled: "Proposal, not to engage the clergy any longer when marriages are conducted" and a number of leading intellectuals replied with essays, of which Kant's is the most famous and has had the most impact. Kant's opening paragraph of the essay is a much-cited definition of a lack of enlightenment as people's inability to think for themselves due not to their lack of intellect, but lack of courage.
Kantianism is the philosophy of Immanuel Kant, a German philosopher born in Königsberg, Prussia. The term Kantianism or Kantian is sometimes also used to describe contemporary positions in philosophy of mind, epistemology, and ethics.
Karl Leonhard Reinhold was an Austrian philosopher who helped to popularise the work of Immanuel Kant in the late 18th century. His "elementary philosophy" (Elementarphilosophie) also influenced German idealism, notably Johann Gottlieb Fichte, as a critical system grounded in a fundamental first principle.
Rechtsstaat is a doctrine in continental European legal thinking, originating in Dutch and German jurisprudence. It can be translated into English as "rule of law", alternatively "legal state", state of law, "state of justice", or "state based on justice and integrity".
The Law of Peoples is American philosopher John Rawls' work on international relations. First published in 1993 as a short article, in 1999 it was expanded and joined with another essay, "The Idea of Public Reason Revisited" to form a full-length book. Rawls's basic distinction in international politics is that his preferred emphasis on a society of peoples is separate from the more conventional discussion of international politics as based upon relationships between states. It is an attempt to show "how the content of a Law of Peoples might be developed out of a liberal idea of justice similar to, but more general than, the idea I call justice as fairness".
Overlapping consensus is a term coined by John Rawls in A Theory of Justice and developed in Political Liberalism. The term overlapping consensus refers to how supporters of different comprehensive normative doctrines—that entail apparently inconsistent conceptions of justice—can agree on particular principles of justice that underwrite a political community's basic social institutions. Comprehensive doctrines can include systems of religion, political ideology, or morality.
The Metaphysics of Morals is a 1797 work of political and moral philosophy by Immanuel Kant. It is divided into two sections: the Doctrine of Right, dealing with political rights, and the Doctrine of Virtue, dealing with ethical virtues.
Kantian ethics refers to a deontological ethical theory developed by German philosopher Immanuel Kant that is based on the notion that: "It is impossible to think of anything at all in the world, or indeed even beyond it, that could be considered good without limitation except a good will." The theory was developed in the context of Enlightenment rationalism. It states that an action can only be moral if (i) it is motivated by a sense of duty and (ii) its maxim may be rationally willed a universal, objective law.
Liberalism and the Limits of Justice is a book about liberalism by the philosopher Michael Sandel. The work helped start the liberalism-communitarianism debate that dominated Anglo-American political philosophy in the 1980s.
