"I was promised on a time - to have reason for my rhyme; From that time unto this season, I received nor rhyme nor reason"

This quote by Edmund Spenser is a reflection on the absence of satisfaction of a pledge. It suggests that the speaker was assured something, however has not gotten it. The speaker is dissatisfied and frustrated that they have not gotten what they were guaranteed. The phrase "rhyme nor reason" is a metaphor for the absence of fulfillment of the pledge. It suggests that the speaker has not gotten any explanation or justification for why the promise was not satisfied. The quote is a reminder that pledges are not constantly kept which sometimes we are left without a description. It is a pointer to be careful when making guarantees and to be conscious of the effects of not fulfilling them. The quote also functions as a tip to be patient and understanding when promises are not kept, as sometimes there is no rhyme or reason for why they are not satisfied.
