Who were the three men sleeping at the bottom of the hill and what do they represent? How does each respond to Christians warning?

Christian warns three men sleeping at the bottom of the hill for incumbent danger, their names were: Simple, Sloth and Presumption and they responded by ignoring his warning.

Explanation:

the three men represent a vice in people who choose not to believe in the christian faith according to the book 'The Pligrim's Progress' by John Bunyan.

Simple represents the lack of spirituality and thought and so he responds with utter indifference, not heading what Christian says. Sloth means lethargy in accepting God, so he does not heed Christian and keeps on sleeping.

Presumption means the belief of self assurance that the man does not need God, so he remains alone and apart from the others while telling Christian he does not need his warning.
