Din fråga i rubriken är ju inte besvarad: "Vad består Kants storhet i?"
Bra grejer kanske, men hur kan sådana enkla och självklara teser finna berömmelse?
Det står nog att finna i tidsandan och att det var inte så vanligt att ifrågasätta och vara kritisk på den tiden det begav sig. okey det var upplysningstid och många ifrågasättanden, men hans sätt var väl lite originellt och genomgripande å sitter det från början hänger det med - Pythagora är ju världskändis även idag för sin gamla sats.
Chatgpt är bra men det var kul att få tänka till.
Hmm bra där. Fick ut lite mer av chatgpt, då jag frågade just hur hans tankar står sig mot modern vetenskap:
Great question! Kant’s idea that the human mind actively structures experience has had a lasting impact on science, particularly in physics, neuroscience, and cognitive psychology. While some aspects have been challenged or refined, the core insight remains influential. Let’s break it down:
1. Einstein and Modern Physics: Kant’s Influence and Challenges
Kant’s View (1781, Critique of Pure Reason)
Space and time are not objective, independent realities but forms of human perception.
We cannot access the “thing-in-itself” (noumenon), only appearances (phenomena) structured by the mind.
Einstein’s Theory of Relativity (1905, 1915)
Space and time are not fixed structures imposed by the mind; they are relative and dependent on motion and gravity.
Challenged Kant’s idea that space and time are universal categories of perception.
However, Einstein agreed with Kant’s idea that knowledge is shaped by the observer (e.g., time dilation means time flows differently for different observers).
🔹 Implication: Kant was partially right—our perception of space and time is not absolute, but it is still structured by the observer’s position. Einstein's relativity replaces Kant's "a priori space and time" with a physical, but observer-dependent, model.
2. Neuroscience and Cognitive Science: Does the Mind Structure Reality?
Kant’s View: The Mind Structures Experience with Categories
The mind imposes structures like causality, space, time, and substance on raw sensory input.
Modern Neuroscience: The Brain is a Predictive Machine
The brain does not passively record reality but actively constructs it.
Predictive coding models (Friston, 2010s): The brain constantly predicts sensory input and adjusts based on errors.
Gestalt psychology (early 20th century) shows the brain organizes raw data into meaningful patterns (e.g., we "fill in" missing visual information).
Studies in perception and hallucinations show how the brain imposes structure even when data is absent.
🔹 Implication: Neuroscience has strongly validated Kant’s claim that the mind is an active constructor of experience rather than a passive receiver.
3. Quantum Mechanics: Can We Know the "Thing-in-Itself"?
Kant’s View: We Cannot Access Reality Directly (Noumenon)
We can only know phenomena (appearances shaped by human cognition).
Quantum Mechanics (20th Century)
Heisenberg’s Uncertainty Principle (1927): The observer affects the observed system—we can’t measure both position and momentum with perfect accuracy.
Copenhagen Interpretation (Bohr, 1920s): The quantum world does not have definite properties until it is measured.
Some interpretations suggest reality does not exist independently of observation.
🔹 Implication: This echoes Kant’s phenomena/noumena distinction—quantum mechanics suggests we may never access an observer-independent reality.
Final Verdict: Is Kant Still Relevant?
✅ What Science Confirms
The brain actively structures experience (validated by cognitive science & neuroscience).
Knowledge is observer-dependent (Einstein’s relativity & quantum mechanics support this).
❌ What Science Challenges
Space and time are not fixed structures imposed by the mind (relativity refutes Kant’s view of space & time as purely mental).
We may access reality in new ways through science (Kant thought noumena were unknowable, but quantum mechanics suggests we might probe deeper).
Conclusion: Kant Was Ahead of His Time
His epistemology (theory of knowledge) is largely confirmed, but his specific categories (e.g., space/time as mental constructs) have been refined.
Science still wrestles with the limits of human knowledge, just as Kant did.
His ideas remain central in philosophy of science, especially in debates on perception, consciousness, and reality.
