I left out these last few sentences. I urgently need you to check them. Thank you.

1) Completely cut off from social life, his characters develop an exceptional acuteness of the senses which makes them lose their sanity.
2) Another common theme of the tales is that of perverseness, which characterizes the narrators’ personality.
3) All the narrators seem to be dominated by emotions, but above all by a perverse impulse to dissolution (annihilation) which leads them to act as they should not act and to confess their crime in the end.
4) Poe believes (or believed?) that this impulse, which is hidden in every material and spiritual portion of the universe, rules the dark side of human behaviour.
5) Linked to the theme of perverseness in that of the double, which foreshadows the modern idea of “split personality”.

2) two or more narrators = "narrators’ "

but only one narrator = narrator's

4) believes in the tale
believed when he wrote the tale

5) in that OR is th at of the double?

1) The sentence seems grammatically and logically correct. "Completely cut off from social life, his characters" suggests that the characters in the tales are isolated from society, and as a result, they develop heightened senses that eventually drive them to madness.

2) The sentence is well-constructed. It states that another common theme in Poe's tales is "perverseness," which is a characteristic of the narrators' personalities.

3) The sentence is coherent and grammatically sound. It implies that all the narrators in Poe's tales are driven by emotions, particularly a perverse urge to self-destruction, causing them to behave improperly and eventually confess their wrongdoing.

4) The sentence seems accurate, but the tense needs clarification. If Poe is no longer alive, it would be appropriate to use "believed" to reflect his past beliefs. If Poe is still alive (which is not the case), then "believes" would be more appropriate.

5) The sentence is well-structured. It explains that there is a connection between the theme of perverseness and the concept of duality in Poe's tales. The idea of the "double" in his stories hints at the modern understanding of "split personality."
