- Title
The KK principle and rotational symmetry.

- Abstract
The proposition that the clock is in O( I w i ) SP c sp is just { I w i : C( I w i ) is a determinate of O( I w i ) SP c sp }. For any other determinate C of O( I w i ) SP c sp , O( I x i ) = O( I w i ) and C( I x i ) = C for some normal world I x i (so R I wx i and R I xw i ). This also means that for any worlds I w i and I x i in the same orbit, there is a unique rotation I r i of the circle such that I r i *( I w i ) = I x i . Moreover, P SB sb = { }, so I z i HT <math altimg="urn:x-wiley:21539596:media:phib12203:phib12203-math-0019" xmlns="http://www.w3.org/1998/Math/MathML"><mo> </mo></math> ht K(W-P SB sb ), so < , > satisfies (1d). But, even though the comparison class is held constant, it by no means follows that one I knows i X in every world in the comparison class for I w i , since the comparison class for a world I x i in the comparison class for I w i may include a world I y i not in the comparison class for I w i (that is just to restate non-transitivity).
