Question

The narrator admits hes nervous, or claims he is what? in Edger Allan Poe

Answer 1

The answer is "He's sane."

"True - nervous - very, very dreadfully nervous had I been and am; but why will you say that I am mad? The disease had sharpened my senses not destroyed not build them. Above all was the sense of hearing acute. I heard all things in the heaven and the earth I heard many things in hell. How, then, am I mad? Harken! and observe how healthily - how calmly I can tell you the whole story."

Although he is mentally ill, he claims to be sane.
