The fact that pure space is not a quality of things in themselves but a form of our sensuous faculty of representation, renders all objects in space as mere appearances, or representations of our sensuous intuition.
#ImmanuelKant
#Prolegomena
For Kant, geometry rests on the pure intuition of space, and arithmetic on the successive addition of units in time. Space and time are a priori intuitions underlying all empirical intuition. A priori intuition concerns not the matter of appearance, but its form—space and time.
#Prolegomena
I don't think I can type out the full name of this demo, and I can't copy-paste because it only shows up as JP text in my steam, but the exe called it simply #Prolegomena
While analytic propositions and synthetic #aposteriori judgments are easily understood—the former grounded in contradiction, the latter in experience—the real problem remains: how are synthetic propositions #apriori possible?
#Kant
#Prolegomena
Kant: Although Hume did not formally differentiate between analytic and synthetic judgements, what he said was equivalent to that pure mathematics contains only analytic, but metaphysics synthetic, a priori judgments, in which, however, he was greatly mistaken.
#Kant
#Prolegomena
i.e., either our five fingers or five points; and we must add successively the units of the five given in the intuition to the concept of seven.
Arithmetical judgments are therefore synthetic, and the more plainly according as we take larger numbers.
#Kant
#Prolegomena
#SyntheticJudgments require a different principle from that principle of analysis, or, namely, Contradiction. — There are synthetic a #posteriori judgments of empirical origin; but there are also others which are certain a #priori, and which spring from pure understanding and reason.
#Prolegomena
Then, to say “some bodies are not extended,” is to contradict the concept of the body.
Nothing can both be and not be in the same respect (A and not-A cannot both be true together) – the Principle of Contradiction, the ground of all analytic judgments in Kant’s system.
#Kant
#Prolegomena
There is a distinction in #judgments, according to which they are either merely #explicative, adding nothing to the content of the cognition, or #ampliative, increasing the given cognition: the former may be called #analytic, the latter #synthetic, judgments.
#ImmanuelKant
#Prolegomena
In order to present metaphysical cognition as a science, it's necessary to differentiate its sources, which cannot be empirical and whose principles must never be derived from experience.
#ImmanuelKant
#Prolegomena
I offer in the #Prolegomena such a plan of a general critique of pure reason which is sketched out after an #analytical method, while the #Critique itself had to be executed in the #synthetical style, so the science may present all its articulations in their natural combination.
#ImmanuelKant
Most readers will set out by expecting nothing else from the #Critique, but these #Prolegomena is a perfectly new science, of which no one has ever even thought, and for which nothing hitherto accomplished can be of the smallest use, except it be the suggestion of Hume’s doubts.
#ImmanuelKant
Having tried to put #Hume’sObjection into a general form, #Kant concluded that the concept of the connection of cause and effect was not the only one by which the understanding thinks the connection of things #a_priori, but rather that #metaphysics consists altogether of such concepts.
#Prolegomena
#CommonSense can remain sound by critical reason keeping it in check. #CriticalReason prevents common sense from speculating, or, if speculations are under discussion, restrains the desire to decide because it cannot satisfy itself concerning its own principles.
#ImmanuelKant
#Prolegomena
Hume's question was whether the concept of #cause and #effect could be thought by reason a priori, whether it possessed an inner truth, independent of all experience, not limited merely to objects of experience.
#ImmanuelKant
#Prolegomena
#DavidHume
The analytical method of the #Prolegomena proceeds regressively from conditioned to condition: starts with some uncontested pure knowledge (arithm,etc), needs not inquire as to whether such knowledge IS possible (since it's already actual), but needs to inquire as to HOW such knowledge is possible.
