Transcendental Idealism and Knowledge | Immanuel Kant #1
Summary
TLDRThis 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.
Outlines
📚 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.

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
