why did the peddler think that the world was a rattrap?
Peddler used the metaphor rattrap for the world because as the rattrap is a small cage sort of structure in which the BAIT (temptation) is put and the rats get tempted or attracted towards it and as a result get caught in it ,similarly in this world there are many baits or temptations for us in which we get caught because o our temptations.
