I found Robert Faggen's criticism on "The Road Not Taken" to be very enlightening. He stresses the idea that the word "taken" is used instead of the word "chosen" to suggest that a choice was made on impulse and not through careful consideration. I didn't really pick up on this when I read the poem, but it makes complete sense to me when he explains it in his criticism and helped me to look at the poem in a new light. However, one point he makes at the end of his criticism is a bit unclear to me. He states that since the roads already exist, this implies that human possibility is limited. In my opinion, aside from the occasional dead end, all roads connect and do not end.
