Final Answer:
The author believes cultural perceptions of courage should change because they prevent potential heroes from acting (Option d).
Step-by-step explanation:
The crux of the author's belief lies in the idea that prevailing cultural perceptions of courage act as barriers to potential heroes taking action (option D). The author likely argues that certain societal norms and expectations regarding courage may discourage individuals from stepping into heroic roles. This could be due to fear of judgment, societal backlash, or the perceived inadequacy of their actions in the context of current cultural ideals.
The rationale behind this belief might be rooted in the recognition that courage is not exclusively manifested in grand, heroic deeds but can also be found in everyday acts of bravery. By changing cultural perceptions of courage, the author may advocate for a more inclusive and diverse understanding that encourages and appreciates the varied forms of courage displayed by individuals in different circumstances.
In essence, the author's perspective implies a call for a cultural shift that acknowledges and values the diverse expressions of courage, thus empowering a broader spectrum of individuals to act heroically in their own capacities. This nuanced understanding aims to break down the barriers that might prevent potential heroes from contributing to positive change in society.
