Rationality means setting rational

That sounds circular to me.

The adjective ‘rational’ is just superfluous there; the grandparent should simply remove it.

"Rational," as an adjective for goals, typically means something like "internally consistent" or "long-sighted" or "wise," and so in general "rational goals" and "goals" mean different things. In a definition for rationality, though, it's inappropriate.

I didn't mean that it was superfluous in front of ‘goals’ but that it was superfluous in a definition of ‘rationality’, so we agree about that. And Pringlescan's definition makes sense if it's removed.
