Specifically it focuses on his discussion in the Third Part Of The Transcendental Problem: How is metaphysics in general possible? Specifically this bears upon his discussion about how the ideas of reason involve and aim at a completeness to experience that can never be found in experience itself. He discusses what use these ideas of reason are, and also clarifies the term "noumena"

Immanuel Kant, Prolegomena - Syllogisms And Pure Ideas Of Reason - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Third Part Of The Transcendental Problem: How is metaphysics in general possible? Specifically this bears upon Kant's discussion of the ideas or pure concept of reason, derived from his consideration of three main types of syllogisms (Verstandschlüsse): categorical, hypothetical, and disjunctive. These correspond to the psychological, cosmological, and theological ideas, which figure into the dialectic of reason.

Immanuel Kant, Prolegomena - Phenomena And Noumena - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon the distinction between phenomena and noumena, that is things of sense or appearances, and beings of the understanding. Kant argues that we cannot have any determinate knowledge of the noumena, but we also can know that the phenomena are grounded upon the noumena

Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible?

Immanuel Kant, Prolegomena - Principles Of Possible Experience - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon what Kant calls "principles of possible experience". Principles (Grundsatze) are rules that are not determined by other rules, and these correspond to pure concepts of the understanding. Taken as a totality, they comprise a system which provides the laws of nature, and a pure natural science

Immanuel Kant, Prolegomena - Pure Concepts Of The Understanding - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon his exposition of what he identifies as pure concepts of the understanding (Verstandsbegriffe), which, as he tells us, make possible for us universal, objectively valid judgements. These correspond to the logical table of judgements and to the transcendental table of the concepts of the understanding

Immanuel Kant, Prolegomena - Judgements Of Perception And Experience - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon the distinction Kant makes between two kinds of judgements, those of perception (Wahrnehmungsurteile) and those of experience (Erfarhungsurteille). The latter involve the addition of pure concepts of the understanding, and can yield us a priori cognitions

Immanuel Kant, Prolegomena - Nature And Pure Natural Science - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on his discussion in the Second Part Of The Transcendental Problem: How Is Pure Natural Science Possible? Specifically this bears upon what 'nature" means, what the extent and scope of pure natural science is, and an explanation of how pure natural science is possible. Kant argues that pure natural science cannot be cognition of things as they are in themselves, but rather as falling within the domain of our possible experience, and governed by laws that can be known a priori.

Immanuel Kant, Prolegomena - Avoiding Non-Critical Idealism - Sadler's Lectures
This lecture discusses key ideas from the 18th century philosopher Immanuel Kant's work, The Prolegomena to Any Future Metaphysics.
Specifically it focuses on Kant's defense of his own transcendental or critical idealism from accusations that he turns the spatio-temporal world of sense-experience into mere "illusion" (Schein). Kant explains how illusions do arise out of other philosophical positions and their key assumptions.
