Pure practical reason (German : reine praktische Vernunft) is the opposite of impure (or sensibly-determined) practical reason and appears in Immanuel Kant's Critique of Practical Reason and Groundwork of the Metaphysics of Morals .
Practical reason is reasoning (or the use of reason) that deals with what ought to be (viz., what actions we ought to do). Thus, pure practical reason is the reason that drives actions without any sense-dependent incentives. Human reasoning chooses such actions simply because those actions are good in themselves; this is the nature of good will, which Kant argues is the only concept that is good without any justification, it is good in itself and is a derivative of a transcendental law which affects the way humans practically reason (see practical philosophy). The possibility of pure practical reason is explored in the Critique of Practical Reason where he tackles the question of whether reason by itself, independently of empirical conditions, can be a source of knowledge about what we ought to do, or whether the knowledge about what we ought to do that is given by reason can only be empirically conditioned.

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. He has been called the "father of modern ethics", the "father of modern aesthetics", and for bringing together rationalism and empiricism has earned the title of "father of modern philosophy".
Reason is the capacity of consciously applying logic by drawing valid conclusions from new or existing information, with the aim of seeking the truth. It is associated with such characteristically human activities as philosophy, religion, science, language, mathematics, and art, and is normally considered to be a distinguishing ability possessed by humans. Reason is sometimes referred to as rationality.
Will, within philosophy, is a faculty of the mind. Will is important as one of the parts of the mind, along with reason and understanding. It is considered central to the field of ethics because of its role in enabling deliberate action.
In philosophy, a noumenon is knowledge posited as an object that exists independently of human sense. The term noumenon is generally used in contrast with, or in relation to, the term phenomenon, which refers to any object of the senses. Immanuel Kant first developed the notion of the noumenon as part of his transcendental idealism, suggesting that while we know the noumenal world to exist because human sensibility is merely receptive, it is not itself sensible and must therefore remain otherwise unknowable to us. In Kantian philosophy, the noumenon is often associated with the unknowable "thing-in-itself". However, the nature of the relationship between the two is not made explicit in Kant's work, and remains a subject of debate among Kant scholars as a result.
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.
A hypothetical imperative is originally introduced in the philosophical writings of Immanuel Kant. This sort of imperative is contrasted with a categorical imperative.
The Critique of Pure Reason is a book by the German philosopher Immanuel Kant, in which the author seeks to determine the limits and scope of metaphysics. Also referred to as Kant's "First Critique", it was followed by his Critique of Practical Reason (1788) and Critique of Judgment (1790). In the preface to the first edition, Kant explains that by a "critique of pure reason" he means a critique "of the faculty of reason in general, in respect of all knowledge after which it may strive independently of all experience" and that he aims to decide on "the possibility or impossibility of metaphysics". In this context, a "critique" means a systematic analysis, rather than finding fault, unlike the term's colloquial use.
Compatibilism is the belief that free will and determinism are mutually compatible and that it is possible to believe in both without being logically inconsistent. As Steven Weinberg puts it: "I would say that free will is nothing but our conscious experience of deciding what to do, which I know I am experiencing as I write this review, and this experience is not invalidated by the reflection that physical laws made it inevitable that I would want to make these decisions." The opposing belief, that the thesis of determinism is logically incompatible with the classical thesis of free will, is known as "incompatibilism".
Transcendental idealism is a philosophical system founded by German philosopher Immanuel Kant in the 18th century. Kant's epistemological program is found throughout his Critique of Pure Reason (1781). By transcendental Kant means that his philosophical approach to knowledge transcends mere consideration of sensory evidence and requires an understanding of the mind's innate modes of processing that sensory evidence.
The Critique of Judgment, also translated as the Critique of the Power of Judgment, is a 1790 book by the German philosopher Immanuel Kant. Sometimes referred to as the "third critique", the Critique of Judgment follows the Critique of Pure Reason (1781) and the Critique of Practical Reason (1788).
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.
Prolegomena to Any Future Metaphysics That Will Be Able to Present Itself as a Science is a book by the German philosopher Immanuel Kant, published in 1783, two years after the first edition of his Critique of Pure Reason. One of Kant's shorter works, it contains a summary of the Critique‘s main conclusions, sometimes by arguments Kant had not used in the Critique. Kant characterizes his more accessible approach here as an "analytic" one, as opposed to the Critique‘s "synthetic" examination of successive faculties of the mind and their principles.
"Critique of the Kantian philosophy" is a criticism Arthur Schopenhauer appended to the first volume of his The World as Will and Representation (1818). He wanted to show Immanuel Kant's errors so that Kant's merits would be appreciated and his achievements furthered.
In Kantian philosophy, a transcendental schema is the procedural rule by which a category or pure, non-empirical concept is associated with a sense impression. A private, subjective intuition is thereby discursively thought to be a representation of an external object. Transcendental schemata are supposedly produced by the imagination in relation to time.
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 "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 it is motivated by a sense of duty, and its maxim may be rationally willed a universal, objective law.
A priori and a posteriori are Latin phrases used in philosophy to distinguish types of knowledge, justification, or argument by their reliance on experience. A priori knowledge is independent from any experience. Examples include mathematics, tautologies and deduction from pure reason. A posteriori knowledge depends on empirical evidence. Examples include most fields of science and aspects of personal knowledge.
Natural Law and Natural Rights is a book by John Finnis first published by Oxford University Press, as part of the Clarendon Law Series. Finnis develops a philosophy of Law in the tradition of Aristotle and Thomas Aquinas – Natural Law. His presentation and defence of Natural Law can be explored from three perspectives. First, polemical, by contradistinction with other philosophies of Law. Second, through its particular methodology, based on practical reasoning. Third, through its substantive content in the form of basic human goods. In addition, his 2011 edition included an extensive postscript, which is briefly discussed in the fourth section. The book is written as a collection of essays on a wide range of topics guided by an overall theme.
Transcendental humanism in philosophy considers humans as simultaneously the originator of meaning, and subject to a larger ultimate truth that exists beyond the human realm (transcendence). The philosophy suggests that the humanistic approach is guided by "accuracy, truth, discovery, and objectivity" that transcends or exists apart from subjectivity.
