Commentary Par IV 19-27

Beatrice addresses the nature of Dante's questions.  The first concerns the apparent fact that even a person who never ceases willing the good, and who ceases doing good only by virtue of the force of others, is in some way responsible for that failure.  The second, zeroing in on a problem that we frequently encountered throughout the previous canto (see C.Par.III.29-30), concerns the ultimate abode of the blessed: whether or not they return to dwell forever in the stars that most shaped their personalities.  This is the more pernicious of these two dangerous questions and will thus be addressed first, if at lesser length, in vv. 28-63 (Beatrice's answer to the first question will be found at vv. 64-114).
