The closing illustration also mentions people overwhelmed by entrenched suspicions and doubts while neglecting the Hereafter. The two deficiencies can reinforce each other: careless reasoning undermines confidence in evidence, while indifference to accountability weakens conduct.
Intellectual defect: allowing vague suspicions to replace fair inquiry and established evidence.
Behavioral defect: making choices with little regard for their moral consequences, trust or justice.
A sincere question should not be confused with deliberate evasion of evidence. Questioning is constructive when one is willing to seek and assess an answer honestly. Remembering the Hereafter likewise requires attention to the consequences of both one's beliefs and one's actions. The lesson links intellectual integrity and moral accountability.
