Final answer:
X contains itself and all the x, and changing the parameter P does not generate a revenge version of the Russell paradox.
Step-by-step explanation:
X contains itself and all the x
In this scenario, X is defined as a set that includes all elements x that satisfy some parameter P. However, X itself is not included as an element of X because it is manually inserted into itself, separate from satisfying P. So X contains itself and all the x, with the x being noncircular sets.
Changing the parameter P
Even without the manual insertion procedure, if we change the parameter P from noncircular to noncircular or identical to X, then an element x that is noncircular or x = X would be considered an element of X. This would result in X being a set that includes all noncircular sets and also contains itself, but without generating the Russell paradox.
Revenge version of Russell paradox
In this case, there isn't a revenge version of the Russell paradox that can be formulated. The disjunctive properties are not omitted from the naive comprehension principle, and the set X is guaranteed to be noncircular and free from paradoxes.
