Answer:
These are the lines of "Robert Graves" of the poem "In Broken Images" in this stanza the poet says that the person becomes dull trusting his clear images and contradictory to that another person becomes sharp mistrusting his broken images . So nothing should be taken for granted and one should remain thoughtful and considerate about the fact of life . In this way one can understand his confusion while the other who do not inquire and trust every thing then hast makes the waste.
