Micro-entities were metaphysical speculations in Kant's era --a history also key to why Mach still abhorred granting realism status to later atomistic theories, preferring his "phenomenalism". What Nordmann refers to is science today, and thus part of the study of the phenomenal world. Kantians, however, can still contend that our detections and technical descriptions of atoms / particles in experience are not what they are as things-in-themselves (their "external" existence as not processed into knowledge / experience / comprehension).chaz wyman wrote:thalarch wrote:Daniel1974 wrote:I will just say
But first, it's "time" to render this sub-topic moot by my not straying into or further accomodating its error. In Kant's critical philosophy, science studies and researches the phenomenal world, not the noumenal world that speculative and dogmatic metaphysics projected doctrines upon (which is the one Kant leaves a blank, neutral placeholder deprived of the Aristotlean categories, time and space, etc.). Alfred Nordmann of the
Darmstadt Technical University expresses this neatly:
"If you want to know what noumena or things-in-themselves are, consider things like atoms or molecules. After all, we cannot directly experience them and yet our phenomenal world of experience is composed of them. This interpretation is obviously incorrect because we formulate and test scientific theories about atoms and molecules.
No this is exactly correct and very perceptive. Kant would have approved. Whatever way you look at it, atoms and sub atomic particles are just models, and all models are subject to change as we are continually seeing in atomic physics.
Such things are beyond our phenomenal understanding and are imperceptible; against common sense. We can never conceive of a atom which is supposedly empty space with virtually invisible particles. Kant meant exactly this.
These are therefore objects of knowledge and it was precisely for all objects of knowledge that Kant showed how we constitute them as phenomena in time and space, as subject to causality, etc. As far as science is concerned, atoms and molecules are definitely no things-in-themselves that are unstructured by our minds. As objects of knowledge they come with, they are part and parcel of our theoretical representations."
Atoms are exactly things in our minds. This does not mean that they are not part of the external real world, but it does mean that they are conceptualised reality; models by which our understanding of the world is enhanced.
