The following line from Utopia is an example of an analogy:

They supply or are supplied from one another, so that indeed the whole island is, as it were, one family.

An analogy is whenever there is a similarity between two things and therefore a comparison can be easily made. In this case, the people "supply and are supplied from one another", this is similar to a family. A family is characterized because all the members of the family aim for the wellbeing of each other, and as a result, all the members contribute and share.
