Final answer:
The irony of the blind man's movement is the challenges and ridicule faced by someone who gains sight. This can be seen in Plato's allegory of the cave and the story of the blind men and the elephant.
Step-by-step explanation:
In the context of the provided texts, the irony of the blind man's movement refers to the paradoxical situation where someone who was blind and then gained sight would face challenges and suffer ridicule.
In Plato's allegory of the cave, the prisoner who was freed from the chains and exposed to the reality outside the cave would initially struggle with the painful sensations and overwhelming new experiences.
Similarly, in the story of the blind men and the elephant, the blind men are unable to see the full truth of the elephant because of their limited perspectives.
