|Sensory Impressions||Sensory Impressions/Sellars: distinguished from pieces of the given. No direct relationship with the knowledge.
Active receptivity. But the receptivity cannot cooperate itself in a rational manner with the spontaneity. (VsQuine). (Where?)
Sellars: no renunciation of sensations in toto. (Unlike Quine).
Sensory Impressions/Quine: manifolds, which are to be structured through various theory drafts. (SellarsVs).
Sellars: Physical and mental are not in a causal relationship, but belong to different world views. Only conveyed by structure of world views. (Vs above). The frames are related by their structure and not by content. It is simply a wrongly asked question how impressions and electromagnetic fields can tolerate each other.
Theory of sensory impressions does not speak of inner objects.
Sellars: sensory impressions only have causal consequences of external physical objects. A red sensation can also occur if the external object only seems to be red. Both concepts explain why the speaker always speaks of something red. Only, the sensation is according to Sellars no object of knowledge, and even the category of the object is questioned by Sellars.
First, however, these states are states of a person. Not of a brain. In any case, they are imperceptible.
Sensory Impressions: neither they have a color, nor do they have a shape. (> Perception).
Impressions: that these are theoretical entities, is shown to us by how to characterize them in an intrinsic way: not only as descriptions: "entity as such, that looking at a red and triangular object under such and such circumstances has the standard cause." But rather as predicates.
These are no abbreviations for descriptions of properties. Example if one says that molecules have a mass, then the word "mass" is not an abbreviation of a description of the form "the property that ...".
"Impression of a red triangle" does not only mean "impression like he ... through red and triangular objects ...." although it is a truth, namely a logical truth about impressions of red triangles.
Impressions need to be inter-subjective, not completely dissolvable impressions in behavioral symptoms: states (but not physiological) - impressions are not objects.
Sellars: Rylean Language: actual explanation, is more than just a code: conceptual framework public objects in space and time - Language of impressions: embodies the discovery that there are such things, but it is not specifically tailored to them (individual things no antecedent objects of thinking).
VsHume: because he does not clearly distinguish between thoughts and impressions, he can assume that a natural derivative corresponds not only to a logical but also a temporal sequence. His theory must be extended so that it also includes cases such as the above or backwards: Thunder now, before a moment of lightning.
Hume does not see that the perception of a configuration is also the configuration of perceptions.
