"Ah Bartleby! Ah humanity!

Early on the narrator describes himself as "an eminently safe man.". He admittedly takes the path of least resistance, he is perfectly satisfied with the way his life is going and largely unconcerned with the welfare of others. Bartleby's plight brings out the narrator's humanity. He even leaves his office rather than have Bartleby removed. He even goes o far at one time tp offer Bartleby a place in his own home. When Bartleby ends up in jail, the narrator bribes one of the jailers to make sure that Bartleby is properly fed and cared for, something he would not have considered doing previously. He, the narrator, has realized his connection to humanity, hence the famous final lines,"Ah Bartleby! Ah humanity!"
