The poem gives close resemblance to human life. The images used in the poem describe human

The human tendencies are: 

1. to create unnecessary dispute without accepting the obvious fact – ‘To which the said spectacles ought to belong.’ 

2. To be unreasonable, just to prove one’s point and be a winner. One does not even need to know the validity of the argument – ‘That the Nose had spectacles always in war’. 

3. Quickly shift the side even after knowing that it can cause a big damage – ‘He pleaded again in behalf of the Eyes’.

4. To pass a judgement without considering the adverse effect it can lead to – ‘By daylight or candlelight – Eyes should be shut’.
