I fail to see how the author of this piece is the one who called those things “perversity”, here is a direct quote from the piece that refutes your claim:
> he wrote about what he called perverseness: the “unfathomable longing of the soul to vex itself”—the mysterious desire he felt, and believed we all feel, to get in our own way.
> Perverseness, Poe thought, was as fundamental a drive as hunger or libido, with its own dedicated region of the brain. When we are perverse, we turn not only against our better judgment but also against what are apparently our desires. “The Imp of the Perverse” begins with an essay defining the concept and giving examples that range from the harmless to the unsettling; Poe classes as perverse both procrastination and the impulse to kill oneself by jumping from a great height.
Where does the author define the things that are perverse? All are attributed to Poe.
