It is possible to identify the use of explicit comparison, in the text above, when the author uses the words "like" or/and "as" to establish the comparisons. Implicit comparison, on the other hand, is identified when the author makes comparisons without the use of these two words.
In this regard, we can see two examples of implicit and explicit comparisons, in the lines below, which were taken from the text:
- "The sister arts enjoy the use of a plastic and ductile material, like the modeller's clay, literature alone..."
- "Nor Is this all; for since these blocks, or words, are the acknowledged currency of our daily affairs, there are here possible none of those suppressions..."
It is important to emphasize that implicit and explicit comparisons are made from figures of speech. These figures are:
Simile: Establishes an explicit comparison between two elements that have similarities.
Metaphor: Establishes the implicit comparison between two elements that do not have direct similarities.
