|Sense Data Theory||Hintikka I 78
Sense data/Russell/Hintikka: a) given by the senses, therefore deception possible - b) at the same time they do not belong to the psychic process of perception - but they are their objects, their content.
Sense data/WittgensteinVsRussell/Hintikka: no physical objects. - Much broader: he needs them for semantic purposes: as the building blocks of all logical forms - as well as the substance of all possible situations. - Subject: is itself not an object.
Whether an object is simple or complex, is empirically not question the logic.
Sense data/Moore/Hintikka: makes a difference between spot and its color. Only the spot belongs to the sense data. WittgensteinVsRussell: they are logical constructions - they simplify laws but are not necessary for them. - Later: (note § 498): "private object before my soul."
Sense data/Russell/Hintikka: fails to uphold a strict distinction between a sense datum as a naked individual thing and a sense datum as a complex object.
Sense data/Wittgenstein/Hintikka: middle and late period: the world in which we live is the world of sense data.
Sense data/Wittgenstein: the sentence is a judgement on the sense data, a reading of one's own sense-data, for example, this is red. Here, there is no need for further verification, that is a priori.
Sense data/physical event/Wittgenstein: the physical sound has a duration, the corresponding sense datum not - Listening and remembering are quite different. - Pointless: to say that one hears something and also recalls it - as e.g. one is seeing while one uses the thermometer at the same time.
Sense data/WittgensteinVsRealism: sense data and physical objects are not in a causal relationship with each other.
The relationship between objects and sensations is linguistically - and therefore necessary.
Sense data/term/Wittgenstein: sense data is the source of our terms.
The world in which we live, is the one of sense data - but the one of which we speak is that one of physical objects.
Sense data/Wittgenstein: it is nonsense to speak of the relationship between object and sense datum.
Senseless: to speak of the causes of my sense data.
