The reason why a critical thinker should bracket metaphorical, proverbial, and other forms of symbol language is because, if they are not, they may cause misconceptions and misunderstandings hence defeating the purpose which they were used.
What are the scenarios that exemplify the above?
Metaphor:
"We are all pencils in the hand of the creator." This was hung above the door in the stationery shop.
Proverb:
"A stich in time saves nine" why not start on time?
Symbolic language:
When in need, run to the cross.
As you can see these statements should not be mixed with other parts of the text. Hence the reason why they should be separated using a bracket.
