"The Thorn" and Moss

"The Thorn" is about the energy that resists change, and how that energy can be found both in nature and in society.  The first natural example Wordsworth uses is that of the moss pulling down the thorn: "With plain and manifest intent/To drag it to the ground."  Here the moss acts on behalf of nature; there is almost a natural drive for the thorn to be with ground yet again.  Wordsworth then extends this metaphor to the baby by having the moss cover it in a similar way.  The baby offered change for the woman by bringing "Her senses back again".  The woman's reputation in society was momentarily lifted, but the moss, red with the baby's blood, has laid claim to something again, and has returned that thing with the earth.  Wordsworth may be arguing that, at least at the time, equality for woman was 'out of tune' with the society he lived in, but at the very least he is stating that the same energy, the energy that resists change, can be found in nature as well as in society.
