In the Minister's Black Veil by Nathaniel Hawthrone.

What reasons does Hooper give for not wanting to remove his veil?

I came up with one reason: that there is a Black Veil on everyone

But what will the other reasons be?

"Why do you tremble at me alone?" cried he, turning his veiled face round the circle of pale spectators. "Tremble also at each other! Have men avoided me, and women shown no pity, and children screamed and fled, only for my black veil? What, but the mystery which it obscurely typifies, has made this piece of crape so awful? When the friend shows his inmost heart to his friend; the lover to his best beloved; when man does not vainly shrink from the eye of his Creator, loathsomely treasuring up the secret of his sin; then deem me a monster, for the symbol beneath which I have lived, and die! I look around me, and, lo! on every visage a Black Veil!"

That's the paragraph where I have to find the reasons

I have never understood this story very well. Maybe it's because I have never understood why the New England colonists did what they did, believed what they believed, etc.

There may be something in one of these sites that can help you with this:

Read especially the second and third articles. Skip all the cheat sites (those that provide essays for you to buy)!!

Frankly, I never understood it either. He claimed it represented a cloak of sin covering him, and others as well. At the maidens funeral, he claimed it prevented the dead maiden from looking on him.

I suspect Hawthorne had something in mind, but I know it not.

The hint is that he "sinned" with the maiden and his guilt would be written across his face.

Aha! I don't remember that, but it'd make sense. Maybe I should read that story again!

In "The Minister's Black Veil" by Nathaniel Hawthorne, the reasons the character Hooper gives for not wanting to remove his veil are as follows:

1. The Black Veil represents the sin and darkness that is present in all individuals: Hooper believes that everyone wears a symbolic black veil, meaning that every person has secrets, guilt, and hidden sins. By wearing the physical black veil, he is making this hidden truth visible to others. He suggests that people should not only fear him and his veil but also their own inner darkness, emphasizing the idea that no one is truly free from sin.

2. The Black Veil is a reminder of the secret and hypocritical nature of society: Hooper challenges the spectators by questioning why they tremble and avoid him alone. He questions whether people's fear and avoidance are truly caused by his black veil or if it is because they are reminded of their own hidden sins and guilt. He believes that society is full of hypocrisy and he himself is a reflection of this truth.

3. The Black Veil symbolizes the mystery and awe of the human condition: Hooper suggests that the black veil is not just about his own personal guilt but represents a deeper mystery that everyone should contemplate. He believes that when individuals open up and reveal their true selves to one another, when they face their own sins and fears, only then can they truly understand and accept the human condition.

Overall, Hooper's reasons for wearing the black veil go beyond his own personal guilt and are intended to provoke introspection and self-reflection among those who observe him.
