Immanuel Kant is the turning point in modern philosophy where the previous controversies of rationalism and empiricism are renewed. Their question is how is the experience possible? The Limits of the Level of Knowledge What is the basis of a moral duty? How it is possible to make an aesthetic decision How can a human being think independently? 30.1 Changes to the Copernican System Kant proposes that in knowledge the mind is not merely a passive receptacle of material coming from outside. Knowing contributes to the structure of perception. Space and time organize experiences into forms of perception and categories of intelligence. For this reason, I know things as they appear to me in my experience. the knowledge of what things are in themselves is limited. 30.2 Before and after the experience Kant gives new depth to the distinction between a priori and a posteriori knowledge. Also, discussing the difference between analytic and synthetic judgments, synthetic a priori asks for the possibility of knowledge. His project of understanding the universality of mathematics and natural sciences deals with this question. 30.3 The phenomenon and the noumenon The phenomenal world is known in terms of experience. The concept of noumenon or object-in-itself marks the limit of knowledge: no direct knowledge of the simple, invisible world. Without this nuance, it would be misleading to summarize Kant as saying that we cannot know reality. 30.4 Causality and the challenge of Hume The Causality of Hume had a profound effect on Kant. Kant considers causality to be the necessary intellectual category of not only habits formed later from experience, but also experiences understood in an objective order. In this way, he seeks to preserve the universality of scientific knowledge but also to clarify the limits of knowledge. 30.5 Ethics: Autonomy and the Duty of In Kant 's moral philosophy, man himself is a law-making rational being. Ethics is not based solely on external rewards or desires. The categorical imperative demands that individuals act on rules that can become universal laws. Another popular version says to treat humanity as always, not just a means to oneself or another person. The modern notion of human dignity is deeply connected to this idea. 30.6 Universality and equality Kant 's moral universals are powerful because they can challenge moral privilege. If the rules are the same for rational persons, it is difficult to have separate moral rules based on birth, rank, or personal gain. Parallel philosophies regard this universal urge as an important agent of a dignity-based morality. 30.7 But the Sovereign is of human origin. Many times throughout history, universal language assumed the experiences of particular social groups to be normal human experiences. The experience of female colonized societies, racially excluded communities, laborers, slaves, or racialized communities remained outside the definition of philosophical humanities. So giving up universalism is not the solution. universalism must be filled with more real inclusion. The Historical Limits of the 30.8 Kant Some ideas about race and human diversity in Kant 's writing are the subject of serious criticism today. It is not right to hide this fact from philosophical history. A thinker 's great moral principles and his historical prejudices can coexist in the same person. The parallel method makes these contradictions the subject of study rather than removing inconvenient facts. Freedom of speech 30.9 The natural world seems to be subject to the laws of causation; moral responsibility demands the notion of freedom. Kant tries to handle this tension through the phenomenon / noumenon distinction. This solution is widely debated, but the question remains: if every action of mine is determined by a chain of causes, then what is moral responsibility? 30.10 Public Conscience and the Enlightenment Kant links enlightenment to the courage of individuals to make public use of their intellect. The exercise of free conscience, coming out of a state-directed puberty, constitutes the crucial norm for modern citizenship. But for the real exercise of public conscience, education must entail freedom of expression and social equality. It is insufficient to say that hunger, ethnic oppression, gender inequality or colonial subjugation can only be exploited. 30.11 Comparative Dialogues with Indian Philosophy Kant 's questions of the limits of knowledge and the conditions of experience can open a dialogue with many traditions of Indian philosophy, such as Nyaya 's objective knowledge, Buddhist epistemology, and Vedanta 's epistemological questions. But it is not right to make a direct equivalence. Comparison is fruitful when the problem- structure is clear, not just word-for-word similarity. Pūrvapakṣa (Prima Facie View): Kant 's universal morality is highly abstract. The objection is that real social relations, emotions, history and inequality are not adequately encapsulated in abstract laws. Uttarapakṣa (Response): Criticism is appropriate, but universality itself is not. Without universal dignity, powerful groups can make their own special rules. What is needed is a solid analysis of the universal moral criterion + historical inequality. 30.12 The decision of the synthesizing antecedent Kant 's fundamental question is how it is possible to have knowledge that enhances experience, but not merely generalizes specific experiences. Some basic decisions in mathematics and the natural sciences are examples of synthetic precedents for them. While adding new things to the subject of empirical methods, these empirical methods do not derive their necessary justification from experience alone. Not every example of this classification is without controversy. The question arose again after the development of modern mathematics and science. The philosophical significance, however, is that it can be difficult to reconcile knowledge with only semantic truth and empirical fact. The very fact that knowledge is possible makes it a subject of investigation. 30.13 The Form of Sensation: Space and Time Kant considers space and time to be the antecedents of human consciousness, rather than independent entities. What is found in experience is found in spatial or temporal settings; therefore, we cannot directly claim the objectivity of space-time outside of experience. To call this a prediction of the modern theory of relativity is incorrect. Kant 's questions concern transcendental conditions of knowledge. the questions of modern physics concern the empirical-mathematical theories of motion and gravity. Dialogue is possible, historical equality is not. 30.14 Degree of intelligence and experience The senses provide the material, but experience as objects requires unity of intellect and conceptual quality. For matter and unity are not mere marks copied from outside; they make experience decisive. Here the mind is not the arbitrary creator of the world but the active organizer of experience. The objection is to how Kant proves the completeness of the given quotas. Whether the concept of a different language or culture changes the organization of experience. Parallel philosophy acknowledges Kant 's active Enlightenment but adds socio-linguistic diversity more explicitly. 30.15 Autonomy and the ethical rules Moral autonomy does not mean doing whatever the mind wants; it means accepting rules that apply equally to all reasoning individuals. A person is not just a means but a goal in itself. This was because coercion and exploitation degraded a person 's rational status. But the critique of whether abstract rationality adequately captures body dependence, care and social inequality is significant. Dignity-based ethics associate autonomy with suffering, interdependence, and equal status and fair opportunity. 30.16 The Purpose of Beauty and the Common Decision Beauty judgments claim shared acceptance, beginning with personal pleasure. Just because it 's beautiful is not the only thing you like to say; however, it cannot be forced by perceptual evidence. Kant finds the basis for this strange universal claim in the free harmony of imagination and intellect. Aesthetics are not exempt from social training and authority. The question of what art should be considered prestigious, whose language should be literature, and whose craft should be relegated to the margins gives Kant 's abstract structure a historical test. Common judgment requires open criticism, not dominant standards. Chapter Conclusion Kant posits the active role of knowledge, the limits of experience, and the structure of causality as powerful forms of moral autonomy and universal dignity. Parallel philosophies, while acknowledging their universality, question their historical limits. Universalism would be just if the word human truly included all humans.
