Perception/ChisholmVsTradition: Appearance rather than feeling - adverbial speech: "feels reddish" - cannot be comparative - hallucination: here it depends on the mode of experience - appearance: divisible> sense data language is permissible. See also
phenomenological language., >
Sense data. - perception: it is epistemically evident to me that the object is there - transcendent evidence: judgment about the object is related to me - perceptible properties: secondary qualities - 1. primary qualities: indirect attribution of a property, 2. non-propositional: the subject takes possession of the property true, self-presenting - does not imply the object .

Perception/Knowledge/Theory of Knowledge/Chisholm: Epistemic Principle 9 de re: x is such that it is evident to x that it is F (less pure) - not applicable if thing does not exist - not to reveal existence non-reflectively, not self-presenting.

Negative perception: seems to demand incompatibility, but it does not have to - Russell: negative perception: empirical propositions, directly known, not developed - Chisholm: e.g. hear nothing: psychological state - negative perception/Whitehead: creates consciousness in first place. - Chisholm pro: Awareness of one's own intentional attitudes.

Perception/Rutte: more than experience: taking an external through the senses - experience: could also be purely immanent.

II 24
Aporia of perception/Hartmann: how is correspondence possible if the one is consciousness-immanent and the other consciousness-transcendent? - Causing of experiences has very different properties than having experiences.
II ~ 25
Perception problem: not whether we perceive things as they are, but whether we can infer from our experiences a causer. - Rutte: experience-like core of the immediate given (SellarsVs) - perception/Rutte: effect of the object evokes a legal order of experience which causally determines the experiences and provokes expectations.
II 27
Perception/Helmholtz: not as an image of properties but their "indications". These are interpreted on the basis of hypotheses - the mode of appearance of a thing is structurally reflected in a certain regular order of our sensory experiences. Hypothetical realism: Schlick, Kraft, Popper, Konrad Lorenz et al.
II 34
Perception/Rutte: success/failure already presupposes realism. - linguistic analytical philosophy: criteria for deception - Berkeley: does not exist. VsBerkeley: then there is not even a conceptual distinction of hallucination, but this is presupposed by Berkeley himself.
II 36
Realism/Truth/Rutte: whoever wants to know whether there are outside things can perhaps guess the truth about it - there is no truth-oriented way to find it out because no successes or failures can be demonstrated that might speak for or against the assumptions.
