Observational terms/Theoretical Terms/TT/Peacocke: Square: has to be experienced as such - an X-ray tube not.
>Observation terms, >Observation language.
For scientists, the X-ray tube can be constructed entirely different, for lay persons not - different term.
Sensitivity for the property: necessary but not sufficient condition.
E.g. "tomato-like": appearance or taste, no theory is required.
Square: a minimal theory of perspective is required.
There is nothing "square-like" what would correspond to "tomato-like".
>Properties, >Predicates, >Perception, >Seeing, >Knowledge,
>Categorization, >Perspective, >Terms.
Without square term no sensation of square, (not only no representation).
A perspectively distorted square is perceived as a square, but not perceived as distorted.
Higher order; >description levels.
Not so with "tomato-like": something that is tomato-like cannot be known as a tomato.
>Forgeries.
"Tomato-like" is not a criterion, otherwise tomato is an observation term. - Representation: tomato, not "tomato-like"
>Representation, >Criteria, >Knowledge.

Theoretical Terms/Peacocke: every perception has representational content - e.g. "The particle collision produced the track".
>Representational content, >Conceptual content, >Content, >Perception, >Causality, cf. >Measurement.
Problem: then the causality is in the representational content, then we have a priori knowledge.
Solution: observational terms and perception must be characterized simultaneously - applying only for observed content (not for theoretical terms). - The experience must also be made if the object is not covered by these theoretical terms.

Particle pair/observation terms/theoretical terms/Peacocke: here, not the same conditions apply for changing angle, etc. - one can imagine here that the track of the particle pair in the cloud chamber does not result from a particle collision. - Unlike e.g. square - but that does not mean that squareness would be a secondary quality in the sense of power to evoke a feeling.
I 101
Theoretical Term: when a perceived object falls below a theoretical concept, then there must be a level of representational content on which the experience could be made, even if the object does not fall under this theoretical term - just thereby "track caused by a particle collision" turns into a theoretical term.

'As'/seeing-as/perception/thinking/Peacocke: E.g. 'This acid burns the table': only liquid is seen, not 'as acid'.},
