"Self-pity does not appreciate pedantry" suggests that when someone is consumed by feelings of self-pity, they often overlook or dismiss detailed, critical analysis or explanations. This statement indicates that in moments of emotional distress, people may prioritize their feelings over reasoned discussions or intricate nuances, highlighting the struggles of those facing personal challenges.

In Alexander McCall Smith's "Bertie Plays the Blues," this quote can reflect the larger themes of the narrative, where characters grapple with their emotions. It emphasizes the need for empathy and understanding rather than getting caught up in minor details, as those experiencing self-pity are often looking for connection and validation rather than intellectual debates.
