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 and controversial figures in modern Western philosophy, being called the "father of modern ethics", the "father of modern aesthetics", and for bringing together rationalism and empiricism earned the title of "father of modern philosophy".
The categorical imperative is the central philosophical concept in the deontological moral philosophy of Immanuel Kant. Introduced in Kant's 1785 Groundwork of the Metaphysics of Morals, it is a way of evaluating motivations for action. It is best known in its original formulation: "Act only according to that maxim whereby you can at the same time will that it should become a universal law."
Groundwork of the Metaphysics of Morals is the first of Immanuel Kant's mature works on moral philosophy and the first of his trilogy of major works on ethics alongside the Critique of Practical Reason and The Metaphysics of Morals. It remains one of the most influential in the field. Kant conceives his investigation as a work of foundational ethics—one that clears the ground for future research by explaining the core concepts and principles of moral theory, and showing that they are normative for rational agents.
Virtue ethics is an approach that treats virtue and character as the primary subjects of ethics, in contrast to other ethical systems that put consequences of voluntary acts, principles or rules of conduct, or obedience to divine authority in the primary role.
In moral philosophy, deontological ethics or deontology is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules and principles, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, utilitarianism, virtue ethics, and pragmatic ethics. In this terminology, action is more important than the consequences.
The Critique of Practical Reason is the second of Immanuel Kant's three critiques, published in 1788. Hence, it is sometimes referred to as the "second critique". It follows on from Kant's first critique, the Critique of Pure Reason, and is one of his major works on moral philosophy. While Kant had already published one significant work in moral philosophy, the Groundwork of the Metaphysics of Morals (1785), the Critique of Practical Reason was intended to develop his account of the will as determinable by the moral law alone, place his ethical views within the larger framework of his system of critical philosophy, and expand on certain themes in his moral philosophy such as the feeling of respect for the moral law and the concept of the highest good.
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.
The concept of universalizability was set out by the 18th-century German philosopher Immanuel Kant as part of his work Groundwork of the Metaphysics 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 maxim is simply a moral rule or principle, which can be considered objective or subjective, or both, or neither, and dependent on one's philosophy. A maxim is often pedagogical and motivates specific actions. The Oxford Dictionary of Philosophy defines it as:
Generally any simple and memorable rule or guide for living; for example, 'neither a borrower nor a lender be'. Tennyson speaks of 'a little hoard of maxims preaching down a daughter's heart, and maxims have generally been associated with a 'folksy' or 'copy-book' approach to morality.
The Kingdom of Ends is a part of the categorical imperative theory of Immanuel Kant. It is regularly discussed in relation to Kant's moral theory and its application to ethics and philosophy in general.
Ethical formalism is a type of ethical theory which defines moral judgments in terms of their logical form rather than their content. The term also often carries critical connotations. Kant, for example, has been criticized for defining morality in terms of the formal feature of being a "universal law", and then attempting to derive from this formal feature various concrete moral duties.
On the Basis of Morality or On the Basis of Morals is one of Arthur Schopenhauer's major works in ethics, in which he argues that morality stems from compassion. Schopenhauer begins with a criticism of Kant's Groundwork of the Metaphysic of Morals, which Schopenhauer considered to be the clearest explanation of Kant's foundation of ethics.
Kantian ethics refers to a deontological ethical theory developed by German philosopher Immanuel Kant that is based on the notion that "I ought never to act except in such a way that I could also will that my maxim should become a universal law.” It is also associated with the idea that “[i]t 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 it is motivated by a sense of duty, and its maxim may be rationally willed a universal, objective law.
The political philosophy of Immanuel Kant (1724–1804) favoured a classical republican approach. In Perpetual Peace: A Philosophical Sketch (1795), Kant listed several conditions that he thought necessary for ending wars and creating a lasting peace. They included a world of constitutional republics by establishment of political community. His classical republican theory was extended in Doctrine of Right (1797), the first part of Metaphysics of Morals. At the end of the 20th century Kant's political philosophy had been enjoying a remarkable renaissance in English-speaking countries with more major studies in a few years than had appeared in the preceding many decades.
Moral rationalism, also called ethical rationalism, is a view in meta-ethics according to which moral principles are knowable a priori, by reason alone. Some prominent figures in the history of philosophy who have defended moral rationalism are Plato and Immanuel Kant. Perhaps the most prominent figure in the history of philosophy who has rejected moral rationalism is David Hume. Recent philosophers who have defended moral rationalism include Richard Hare, Christine Korsgaard, Alan Gewirth, and Michael Smith.
Radical evil is a phrase used by German philosopher Immanuel Kant, one representing the Christian term, radix malorum. Kant believed that human beings naturally have a tendency to be evil. He explains radical evil as corruption that entirely takes over a human being and leads to desires acting against the universal moral law. The outcome of one's natural tendency, or innate propensity, towards evil are actions or "deeds" that subordinate the moral law. According to Kant, these actions oppose universally moral maxims and display self-love and self conceit. By many authors, Kant's concept of radical evil is seen as a paradox and inconsistent through his development of moral theories.
Mary J. Gregor was an American author, translator, and professor.
Allen William Wood is an American philosopher specializing in the work of Immanuel Kant and German Idealism, with particular interests in ethics and social philosophy. One of the world's foremost Kant scholars, he is the Ruth Norman Halls professor of philosophy at Indiana University, Ward W. and Priscilla B. Woods Professor, emeritus, at Stanford University, and has held professorships and visiting appointments at numerous universities in the United States and Europe. In addition to popularising and clarifying the ethical thought of Kant, Wood has also mounted arguments against the validity of trolley problems in moral philosophy.
Aristotle defined inclination in the first paragraph of Metaphysics with the statement "all men by their nature, desire to know." Thomas Aquinas proposed that humans have four natural inclinations - a natural inclination to preservation (life), an inclination to sexual reproduction (procreation), sociability, and knowledge. Inclination in the modern philosophy of ethics is viewed in the context of morality, or moral worth.
Jens Timmermann is a German philosopher and the Professor of Moral Philosophy at the University of St Andrews. He is best known for his research on Kant’s ethics, political philosophy and philosophy of law.
