what rhetorical device is being used in the following: “...to convert our good words into good deeds, in a new alliance for progress, to assist the free men and free government in casting off the chains of poverty.”
The rhetorical device used on that excerpt is metaphor, as one can see on the use of freedom on one side and chains of poverty on the other side. As well, there is a metaphorical treatment on the case of good words to good deeds.
