In a sense, ignorance has now become the order of the day after "three hundred years of slavery."

So pathos is when you try to persuade someone using emotions. An example of it used here is when he talks about the fatigue of travel but no rest. This is effective because everyone can relate to being in need of sleep and hotels should be accessible to everyone.
