“ For the decision "aether or non-aether?", all rotating systems are failing according to the relativity-theoretical view. The existence of the aether is proven, as soon as the following is proven: an inertial system is preferred over another inertial system; thus as soon as one – in the comparison of inertial frames among each other – finds an "effect" of the discussed or of similar kind. On the other hand, every inertial system is preferred over rotating systems from the relativity standpoint, and vice versa ”

“ The rotating relative aether wind of § 4 shall not be used at all from the anti-aether standpoint; the rotating system is, in the sense of the terminology of relativity, no "valid" system at all, i.e., nobody can of course be prohibited to illustrate the actually arising effect by a "relative aether wind", but this is only an image from the standpoint of relativity, like "the sun is rising". ”

“ A potential influence of a possible temporal duration of the reflection process itself, is of course neglected (as it was also done by Sagnac) . My conclusions are also based on the assumption, that the often disputed process of rotation of a rigid system as such, constitutes no problem for the relativity principle. ↑ For example, also for that one (changing continuously) , in which point is present at every moment (in the direction of the circle tangent, the velocity relative to the "rest"-inertial system is as given above) . ”
