Which generalization does the speaker make in the last stanza of to a louse

In the last stanza Burns wishes that we were able to see ourselves as others see us. If we could, we might be able to see ourselves with a little less importance. In the poem the narrator is observing a louse in a woman's bonnet. At first he is disgusted but through the poem he realizes that the individual woman does not matter to the louse--to bugs people are all equal. In this last stanza he thinks about how we would appear if we could see ourselves from that unbiased standpoint. 

Seeing ourselves as others see us would free us from blundering.
