V 33
Perception/Similarity/Quine: transition from perception to perception similarity (perc.sim.) makes perception itself disappear - ontological clarity - similarity: three digit: Episode a resembles b more than c - perception similarity: in contrast, bundle of dispositions of 2nd order (to respond).
V 35
Similarity/Quine: bundle of behavioral dispositions of 2nd order - relative: e.g. red ball, yellow rose - red rose, red scarf: depends on reward whether ball and rose are similar - perception similarity: if four-digit relation, then "viewpoint" superfluous - learning: here, there must be different degrees of similarity! - Otherwise any enhanced relation would equally be conditioned on every future episode, because they would all be equally similar - from that follows that perception similarity standards are innate.
V 37
Classes: do not explain similarity: an object does not have any more class memberships in common with another one than with any third one.
V 39
Similarity/Quine: Episodes: three types of similarity: 1) reception similarity: has to do only with input variables - 2) behavioral similarity: ultimately definable by total quantity of fibers. - 3) perception similarity: somehow in the middle between 1st and 2nd inner state: may be determined by previous stimuli, but not by the present ones! - Reason: perceptual similarity standards are subject to change (through more reward).

VII 12ff
Meaning/Quine: problems: a) "having a meaning", b) equality of meaning: we can explore the latter via behavior, without having to adopt meaning as an entity.
IX 57
Definition "less than"/Quine: y.
XI 108f
Similarity/Logic/Set Theory/Classes/Quine/Lauener: similarity has a dubious logic status: sets do not help in explaining:
XI 109
Things can be freely combined to sets - any two things are common elements of the same number of classes as any other two things - therefore it is not possible to reflect "a is more similar to b than to c" by "a and b together belong to more sets than a and c".
