In his early works, Steiner sought to overcome what he perceived as the dualism of Cartesian idealism and Kantian subjectivism by developing Goethe's conception of the human being as a natural-supernatural entity, that is: natural in that humanity is a product of nature, supernatural in that through our conceptual powers we extend nature's realm, allowing it to achieve a reflective capacity in us as philosophy, art and science.

While he was assimilating the Kantian philosophy and preparing to develop it, fate dealt him a blow: the Rahn family had suffered financial reverses, and his impending marriage had to be postponed.

Though Anstoss plays a similar role as the thing in itself does in Kantian philosophy, unlike Kant, Fichte's Anstoss is not something foreign to the I.

* Anschauung, a related " sense-perception " concept in Kantian philosophy

However, Kant's opinions about the nature of physical objects pervaded the protocol sentence debate, and Kantian opinions of the relationship between philosophy and science were shared by the positivists to some degree.

By the end of the 1870s, a major change had taken place: philosophy of the rationalist or eclectic kind, generally Kantian, had taken over rhetoric as the true end stage of secondary education ( the so-called Class of Philosophy bridged secondary and university education ).

In addition to systematic work in moral theory, Gauthier's main philosophical interests are in the history of political philosophy, with special attention to Hobbes and Rousseau, and in the theory of practical rationality, where he begins from an attempt to understand economic rationality, rather than from Kantian or Aristotelian antecedents.

His other notable university teachers were Christian Philipp Karl Snell ( 1806 – 1886 ) ( subjects: use of infinitesimal analysis in geometry analytical geometry of planes, analytical mechanics, optics, physical foundations of mechanics ); Hermann Karl Julius Traugott Schaeffer ( 1824 – 1900 ) ( analytical geometry, applied physics, algebraic analysis, on the telegraph and other electronic machines ); and the famous philosopher Kuno Fischer ( 1824 – 1907 ) ( Kantian and critical philosophy ).

Though Nietzsche was critical of theories concerning what could not be observed, he believed that theories ought to be capable of being falsified: while arguing against what he held to be the negative influence of the Kantian noumenon in the philosophy and science of his day, Nietzsche roughly approximated the scientific philosopher Karl Popper's assertion that falsifiability was the basis of scientific knowledge:

* Schopenhauer's criticism of the Kantian philosophy

Elias also attempts to refute particular interpretations of his philosophy, such as the notion that much of his thinking was rooted in Kantian secular philosophy.

He was critical of Kantian idealism and proposed his own system of philosophy known as logical ( or rational ) realism.

He dissented strongly from the Kantian distinction between matter and form of thought, and urged that philosophy should consider only thought in itself, pure thought, the ground or possibility of being.

The term " transcendentalism " sometimes serves as shorthand for transcendental idealism, which is the philosophy of Immanuel Kant and later Kantian and German Idealist philosophers.

Supervised by John Rawls, Nagel has been a long-standing proponent of a Kantian and rationalist approach to moral philosophy.

The Wolffian philosophy held almost undisputed sway in Germany until it was displaced by the Kantian revolution, due partly to his distinctive habit of writing in both Latin and German.

In the Biographia this " Theistic faith " appears in its full development ( see the concluding chapter ), and is especially important as perhaps the nearest approach to Kantian ethics made by original English philosophy.

One of the first philosophers to attempt to grapple with Kant's philosophy was Johann Gottlieb Fichte, whose development of Kantian metaphysics became a source of inspiration for the Romantics.

While Mind and World represents an important contemporary development of a Kantian approach to philosophy of mind and metaphysics, one or two of the uncharitable interpretations of Kant's work in that book receive important revisions in McDowell's later Woodbridge Lectures, published in the Journal of Philosophy, Vol.

His best-known work is The Human Intellect, with an Introduction upon Psychology and the Human Soul ( 1868 ), comprehending a general history of philosophy, and following in part the " common-sense " philosophy of the Scottish school, while accepting the Kantian doctrine of intuition, and declaring the notion of design to be a priori.

Schopenhauer's criticism of the Kantian philosophy expresses doubt concerning the absence of egoism in the Categorical Imperative.

According to José Ortega y Gasset, with Post – Kantian German Idealism, "… never before has a lack of truthfulness played such a large and important role in philosophy.

The statement above tells us one more thing: Peirce, having started out in accord with Kant, is here giving notice that he is parting ways with the Kantian idea that the ultimate object of a representation is an unknowable thing-in-itself.

On the other hand, in contrast to Fouillée, he does not see this unknowable itself as able to contribute a " principle practically limiting and restricting conduct ," i. e. of " mere justice " which, he states, comes too close to Kantian notions of duty ; for this, in turn, would bring us back to a theory of moral obligation, which, as the title suggests, he wishes to free moral theory from.

Fichte denied Kant's noumenon and held that consciousness constitutes its own foundation, that the mental life of the Ego, of pure selfhood, relies upon nothing wholly external to itself and that the hypothesis of an outer world of any kind is the same thing as admitting a Kantian realm.

From this perspective, much literary critical theory, since it is focused on interpretation and explanation rather than on social transformation, would be regarded as positivistic or traditional rather than critical theory in the Kantian or Marxian sense.

Derrida states that deconstruction is not a critique in the Kantian sense. This is because Kant defines the term critique as the opposite of dogmatism.

For Derrida it is not possible to escape the dogmatic baggage of the language we use in order to perform a pure critique in the Kantian sense.

" Whereas Aristotle states that one or other of two contradictory propositions must be false, the Kantian law states that a particular kind of proposition is in itself necessarily false.

According to the Stanford Encyclopedia of Philosophy, the " deep tension between the Kantian moral imperatives and a Nietzschean diagnosis of the modern cultural world is apparently what gives such a darkly tragic and agnostic shade to Weber's ethical worldview.

Secular humanism affirms that with the present state of scientific knowledge, dogmatic belief in an absolutist moral / ethical system ( e. g. Kantian, Islamic, Christian ) is unreasonable.

Central to this problem, Habermas argues, is the way Foucault seemingly attempts to remain both Kantian and Nietzschean in his approach.

" t is high time to replace the Kantian question, ' How are synthetic judgments a PRIORI possible?

Mathematics, which at a first sight seems an example of necessarily valid synthetic knowledge derived from pure reason alone, has instead a tautological character, that is its statements are analytical statements, thus very different from Kantian synthetic statements.

* Finally, CLS questions law's central assumptions, one of which is the Kantian notion of the autonomous individual.

Free will, seen this way, is about freedom to make decisions without duress ( and so is a version of Kantian positive practical free will, i. e., Kantian autonomy ), as opposed to an impossible and unnecessary freedom from causality itself.

This concept was called a “ Metaphysical principle ” by Fétis, though Dahlhaus argues that the term is used in this case to denote an anthropological, culturally relative sense in his 1990 book Studies on the Origin of Harmonic Tonality, and theorist Rosalie Schellhous posits that the Kantian term “ transcendental ” might be more appropriate.

Continental philosophers often argue that science depends upon a " pre-theoretical substrate of experience " ( a version of the Kantian conditions of possible experience or the phenomenological concept of the " lifeworld ") and that scientific methods are inadequate to fully understand such conditions of intelligibility.

Jaspers is too often seen as the heir of Nietzsche and Kierkegaard to whom he is in many ways less close than to Kant ... the Kantian antinomies and Kant's concern with the realm of decision, freedom, and faith have become exemplary for Jaspers.

This is often called the Kantian peace theory since it is similar to Kant's earlier theory about a perpetual peace ; it is often also called " liberal peace " theory, especially when one focuses on the effects of trade and democracy.

He preached " positive subversion " and, in a Kantian manner, tried to convince people that using their own intelligence was the right thing to do.

Lonergan is reputed to have integrated classical philosophy with contemporary science and, in the process, to have resolved the Kantian problem of knowing any " thing in itself.
