Transcendental Idealism and Knowledge | Immanuel Kant #1

Summary

This video explores Immanuel Kant's transcendental idealism, a philosophy that bridges empiricism and rationalism. Kant argues for a combination of sensory experience and reason to achieve synthetic a priori judgments, offering universal yet new knowledge. He introduces the concepts of sensibility and understanding, with the mind's innate categories shaping our experience into a comprehensible phenomenal world. The video also discusses the limitations of human reason, suggesting that while some questions may be unanswerable, we should focus on what is within our scope, making science out of what we can experience and understand.

Q & A

What is the main debate in the philosophy of knowledge between 1750 and 1900s?

The main debate was between empiricism, which claimed that all knowledge comes from experience and the senses, and rationalism, which argued that reason and thought alone are sufficient for learning.

What is the problem with empiricism according to Immanuel Kant?

The problem with empiricism is that it suggests absolute knowledge is not possible, as we can never be certain that observed patterns will continue in the future, only that they tend to repeat.

How does rationalism limit our understanding according to the script?

Rationalism limits our understanding because our minds are not entirely independent from experience; we cannot know about things like penguins through pure reason without any sensory input.

What is Immanuel Kant's transcendental idealism?

Transcendental idealism is Kant's theory that combines the strengths of empiricism and rationalism. It suggests that our minds come pre-equipped with concepts that help us understand the world, and that reality is shaped by these concepts into a comprehensible form.

What are the two types of judgment Kant defines in his theory?

Kant defines two types of judgment: analytic judgment, which analyzes a concept and is universal but does not add new knowledge, and synthetic judgment, which adds new information but is not necessarily universal.

Why is a synthetic a priori judgment important in Kant's philosophy?

A synthetic a priori judgment is important because it combines the new information aspect of synthetic judgments with the universality of analytic judgments, which is essential for scientific knowledge.

What is the role of sensibility and understanding in Kant's theory?

Sensibility is the means of contact with the outside world, providing raw data, while understanding uses concepts to process this data into comprehensible and useful information.

What are the three stages in shaping information according to Kant?

The three stages are the transcendental aesthetic, which deals with space and time as tools for organizing our perception; transcendental analytics, which involves applying categories of understanding to organize experience; and transcendental dialectics, where reason builds upon these concepts to create new knowledge.

How does Kant explain the reliability of mathematics?

Kant explains the reliability of mathematics by stating that our minds order everything in space and time, making everything measurable and thus our calculations reliable.

What is the role of categories of understanding in Kant's philosophy?

Categories of understanding are concepts like unity, plurality, causality, and necessity that help organize our experience and make connections between different pieces of knowledge.

Why does Kant consider physics a real science?

Physics is considered a real science by Kant because it connects mathematical principles, which are partly based on internal concepts, with empirical observations, thus fulfilling the criteria for scientific knowledge.

What is the limitation of metaphysics according to Kant?

Metaphysics is limited because it attempts to go beyond our perception and does not have direct empirical support, making it uncertain whether its theories are correct.

📚 Immanuel Kant's Transcendental Idealism

This paragraph delves into Immanuel Kant's philosophy of transcendental idealism, which aims to reconcile the empiricist and rationalist views on knowledge acquisition. Kant critiques empiricism for its inability to guarantee absolute knowledge, as it can only rely on observed patterns without certainty of future occurrences. Rationalism, he argues, is limited by the mind's dependence on experience. Kant introduces the concept of 'transcendental idealism,' suggesting that our minds come pre-equipped with categories that shape our understanding of the world. He distinguishes between analytic and synthetic judgments, the former being universal but uninformative, and the latter providing new information but lacking universality. Kant's theory posits that knowledge is a combination of sensibility (our contact with the world) and understanding (our capacity to use concepts), leading to the possibility of synthetic a priori judgments that are both new and universal.

🌌 Kant's Framework for Knowledge Acquisition

The second paragraph explains Kant's framework for how knowledge is shaped and understood. It outlines three stages: transcendental aesthetic, which uses space and time as tools for organizing sensory input; transcendental analytics, where the mind applies categories of understanding to organize information and form connections; and transcendental dialectics, where reason uses these concepts to create new knowledge. The paragraph emphasizes the interdependence of experience and concepts for generating knowledge, and it discusses the limitations of applying these concepts to ideas beyond experience, such as the self, the world, and God. It concludes by differentiating science, which is based on experience and internal concepts, from metaphysics, which attempts to go beyond perception and lacks empirical support.

Keywords

💡Transcendental Idealism

Transcendental Idealism is a philosophical concept introduced by Immanuel Kant. It suggests that our perception of the world is shaped by the mind's inherent structures, rather than being a direct reflection of reality. In the video, this concept is central to understanding Kant's philosophy, which posits that there are two worlds: the world of experience and the world as it is in itself. Kant argues that our knowledge is limited to the phenomenal world, which is structured by our cognitive faculties, and thus we cannot know the noumenal world, or things as they are independently of our perception.

💡Empiricism

Empiricism is a philosophical theory that asserts all knowledge is based on experience and the senses. In the video, empiricism is contrasted with rationalism as one of the two main currents in the debate over how we acquire knowledge. Empiricists like David Hume argue that absolute knowledge is not possible because we can never be certain that observed patterns will continue in the future. The video uses the example of predicting the future based on past observations to illustrate the limitations of empiricism.

💡Rationalism

Rationalism is the philosophical view that reason and innate knowledge are the primary sources of knowledge. The video explains that rationalism is limited because our minds are not entirely independent from experience. It suggests that without experience, we cannot deduce the existence of things like penguins through reason alone. Rationalism is juxtaposed with empiricism to show the shortcomings of relying solely on reason for knowledge acquisition.

💡Analytic Judgment

Analytic judgment is a type of judgment that analyzes a concept and does not add new knowledge. In the video, it is explained through the example of saying 'Penguins are birds,' which is analytic because the predicate (being a bird) is already contained within the subject (penguin). This judgment is universal and a priori, meaning it is true regardless of experience, highlighting the universality but lack of novelty in analytic judgments.

💡Synthetic Judgment

Synthetic judgment is a type of judgment that adds new information, as opposed to analytic judgment. The video uses the phrase 'The penguin is happy' to illustrate a synthetic judgment, which provides new information about the penguin's state of mind. However, synthetic judgments are a posteriori, meaning their truth depends on experience and are not universally true, unlike analytic judgments.

💡A Priori

A priori knowledge is knowledge that is independent of experience and is known to be true prior to experience. The video explains that analytic judgments are a priori because they are universally true regardless of whether we test them with our experience. This concept is integral to understanding Kant's view on the nature of knowledge and how it can be acquired.

💡A Posteriori

A posteriori knowledge is knowledge that is derived from experience and observation. The video contrasts a priori knowledge with a posteriori knowledge, using synthetic judgments as examples. A posteriori knowledge is not universally true and must be confirmed through experience, such as observing a penguin to determine its emotional state.

💡Sensibility

Sensibility, in Kant's philosophy, refers to the human faculty of receiving impressions from the external world through our senses. The video describes sensibility as the means of contact with the outside world, which provides raw information. It is the first stage in Kant's process of shaping information from the universe, where our minds use space and time to organize our sensory input.

💡Understanding

Understanding, in the context of Kant's philosophy, is the capacity to use concepts to structure and interpret experience. The video explains that understanding works in conjunction with sensibility to create knowledge. It involves the use of categories of understanding, which are concepts that help us make sense of the world and form the basis for synthetic a priori judgments.

💡Categories of Understanding

Categories of understanding are a set of fundamental concepts that organize our experience and make knowledge possible. The video lists categories such as unity, plurality, totality, and causality, and explains how they give coherence and order to our experience. These categories are used to interpret the raw data provided by sensibility and are essential for the creation of synthetic a priori judgments.

💡Transcendental Aesthetic

Transcendental Aesthetic is the first stage in Kant's process of shaping our understanding of the world. The video describes it as the stage where our minds use space and time to organize sensory input, making the world comprehensible. This stage is crucial for the application of mathematics and the reliability of our calculations because it allows us to perceive objects in a spatial and temporal context.

Philosophy, the age of revolution. From  1750 to the 1900s. "There are two worlds:  

The world of experience sensed by our  bodies, and the world as it is in itself".  

Transcendental idealism and knowledge. Immanuel  Kant's analysis. One of the many goals of  

philosophy throughout history has been to define  the way we get to know about things and learn. For  

a long time, the debate had been dominated by two  main currents. On one side there was empiricism  

which claimed that we can only learn through  experience and our senses. On the other hand,  

rationalism proposed that reason and thoughts are  enough to let us learn. Nevertheless, according to  

german philosopher Immanuel Kant both theories  were limited. The problem with empiricism,  

represented by David Hume, is that it inevitably  suggests that absolute knowledge is not possible.  

No matter how much we observe that a situation is  repeating itself, we'll never be able to ensure  

that it is a law. We can't predict the future we  can only stick to the tendency of expecting it to  

happen again, which is a little problematic.  Regarding rationalism, the problem is that  

our minds are limited; therefore, they cannot  be entirely independent from our experience.  

If we have never seen a penguin it would be fairly  impossible to realize that they exist through mere  

reason. None of the options seemed to be complete.  Kant's quest was to create a new and more complete  

theory taking the best of both. He named it  "transcendental idealism". The name might sound  

slightly exaggerated, but it is actually simple.  For Kant, transcendental only means that it is an  

idealism that already comes from our inside. Let's  explain the theory step by step. First, we can all  

agree that our goal is to achieve knowledge  or trustworthy information. That's why we  

have science, right? But, what type of knowledge  can we obtain from it? Kant starts defining two  

types of judgment; That is, two ways in which we  can express knowledge. The first one is analytic  

judgment. As its name suggests it just analyzes a  concept. For example, saying "Penguins are birds".  

This phrase doesn't really add new knowledge  because being a penguin already means being  

a bird. Properly said, the predicate is already  contained in the subject. But the most important  

part is that it is universal knowledge. We'll  never find a penguin that isn't a bird. This  

is a priori knowledge, which means that we can be  completely sure that it is true, even if we don't  

test it with our experience. This is all thanks  to the definition that we humans established for  

the word "penguin". Then, we can conclude that  all information from an analytic judgment will  

be universal but will not add any new knowledge.  On the other side, we have synthetic judgments,  

which do add new information. For example,  "The penguin is happy". This phrase tells us  

something we didn't know about the penguin, but  it has a little problem. It won't always be true.  

The penguin could be sad. To know how our penguin  really is, we'll have to find out by observing  

it. That's why this is a posteriori knowledge.  We cannot affirm it unless our experience tells  

us so. Then, information in a synthetic judgment  is not universal, but it does provide new facts.  

Now, none fulfills the needs of science. We need  judgments that provide new facts, but that are  

universal at the same time. In other words, a  combination. A synthetic a priori judgment. But,  

is this possible? Of course! You see, experience  alone is not universal, and reason alone cannot  

provide new knowledge. But, what if they help  each other? Experience can provide new knowledge,  

and reason can develop it to discover a universal  fact. more rigorously stated for khan the two  

elements that make up knowledge are sensibility  as the means of contact with the outside world and  

understanding as the capacity of using concepts  that is the amazing part of kant's theory but how  

does this collaboration happen according to kant  the human mind already comes programmed with some  

concepts that mold our experience of the world to  make it comprehensible this means that reality or  

the nominal world could be a little different but  thanks to those concepts we can understand it as  

a phenomenal world the outside world provides  raw information without a comprehensible shape  

and our minds provide the tools to give it a shape  and transform it into useful information of course  

this has a process for kant there are three  formality levels or three stages in which we shape  

the information we get from the universe the first  one called transcendental aesthetic is in charge  

of helping our sensibility everything that our  senses can reveal about the world at this point  

the tools that our mind provides are space  and time this means that our minds allow us  

to imagine objects in a place and in a moment  it doesn't really matter if outside ourselves  

space and time aren't real what really matters is  that they are inside ourselves to make possible  

our understanding of the world it is as if time  and space were the lines in a notebook that help  

us write they are just a useful reference that  make the world seem a little more organized  

that's why it is called aesthetic as a  matter of fact can't believe that this  

is the reason why mathematics work since our  brains order everything in space and time they  

also make everything measurable that's why our  calculations are reliable and we can trust them  

once this happens we can move on to the next  level transcendental analytics which deals  

with understanding here our brain will add some  extra concepts that will leave information ready  

to interact with the things we know and become new  knowledge all these concepts are what can't called  

categories of understanding which are 12 unity  plurality totality reality negation limitation  

inverse and subsistence causality and dependence  community possibility existence and necessity  

each of these concepts give a little more  coherence and order to our experience for  

example causality and dependence allow us to get  the cause and effect relation between two events  

the previous stage made perception easier but this  one makes connection easier just as if we were to  

pack our knowledge into bricks that together  can become something bigger these blocks are  

concepts here we have to notice something if  we didn't have experience we wouldn't be able  

to generate concepts but if we weren't able to  generate concepts our experience would be useless  

that is why i can't believe that knowledge  is only possible when we connect sensibility  

to understanding according to kant due to that  physics can also be considered a real science  

since it connects math to experience now that  our knowledge has been packed it can be used  

that is the job of the next level transcendental  dialectics here is where reason comes in in a way  

recent takes the blocks that we created in the  previous level and with them it built something  

new the only problem here is that reason doesn't  always stay limited to the concepts that come from  

our experience for example when we use imagination  or fantasy we work with unreal or false concepts  

sometimes the mind forgets a little about  experience and that is inevitable but we can be  

careful when we watch stars in the sky they seem  to be small but we know that it is an illusion  

they are massive that's how we should deal  with the so-called transcendental ideas  

they include concepts such as oneself the world  and god you see kant never says they are not real  

he just says they are not in our scope the problem  is that they do not come out of experience and if  

we try to apply the categories of understanding  to them it would be like trying to screw using  

a harbor in other words we are not made to turn  this knowledge into measurable science but surely  

we can believe in them for kant although we cannot  prove their existence through a theoretical reason  

these ideas are useful for our minds because  they play an important role in stimulating  

our curiosity and research moreover can't  believe they are also important for morals  

in everything we mentioned previously we have  the key to know what is science and what not  

all knowledge we can derive from and prove  through experience can be science but things  

we can't experiment simply can't be scientific as  we said previously maths and physics are backed up  

partly by experience and partly by our internal  concepts so they are acceptable as science  

but metaphysics isn't as lucky since it tries  to go beyond our perception it simply doesn't  

have a direct backup and we won't ever be sure  that its theories are right to summarize human  

science might be limited since there are things we  cannot perceive but as humans we are not required  

to know about them the best we can do is try to  get the most of the things that are in our scope

human reason is burdened with questions it  cannot dismiss but which it also cannot answer
