In Vladimir Nabokov's book "Despair," the character Orlovius represents individuals who are easily manipulated due to their strong moral compass and emotional tendencies. The phrase "old birds like Orlovius" suggests that those who are experienced or wise can still fall prey to simplicity in judgment when their decency and sentimental feelings cloud their reasoning.

This quote highlights the vulnerability that accompanies having a good heart and being empathetic. While these qualities can be admirable, they can also lead to foolish decisions, emphasizing the delicate balance between being compassionate and being taken advantage of. Nabokov warns of the dangers inherent in such emotional traits, showcasing how they can render even the most seasoned individuals susceptible to deception.
