This might be appeal to ethics if its not then im sorry. The reason I think its ethics is because its the persuasion made on the basis of the character and credibility of the persuader (Abraham Lincoln).
<span>In Dr. Jekyll and Mr. Hyde, the theme “evil
can never truly hide itself” is the underlying theme that connects all the details
together. For some time, the good attributes of the Jekyll/Hyde character were
the only ones people around him see. He was able to hide his evil side in the darkness
of the night. However, a secret that is so hideous cannot be forever hidden
especially that it had consequences that affected the people around him. When his
evil side was beginning to take more control of himself, he could not hide it
anymore.</span>
