comment Infinitely many primes, and Mobius randomness in sparse sets
Dear Joro, Yes, I think we need to regard it as artificial. Probably Problems 2 and 3 are more "imune" against such examples.

comment Logic in mathematics and philosophy
Many thanks Joel, for your answer. As a graet fan (albeit rather ignorant) of both areas (and also of Y. Gurevich) I am certainly happy to hear on stengthening relations between philosophy and set theory/logic.
