I think if you type Oscar Wilde as anything but ENTP, then you don't really know what an ENTP is. It's kind of like saying Einstein is an INFJ or Michael Jordan is an INTJ. Some people really embody what a certain type is supposed to be. I can't think of anyone that embodies ENTP better than Oscar Wilde.
This is not really a good argument, The_Liquid_Laser. I could easily turn it against you and tell you that if you think Oscar Wilde was anything but an NF, you don't really know what an NF temperament is.
I think I understand where you're coming from because my mental image of an ENTP is often very "Wildean". I think it's somewhat ingrained in people's minds that ENTP = charming person with sharp wit. But that doesn't mean that in reality, another type cannot possess the exact same qualities and not be an ENTP. To be honest, even though I can easily "imagine" a Wildean ENTP, the ENTP males I know in real life don't remind me of Wilde in the slightest, and the ENTP females I know are easily comparable when it comes to their intellect, but they aren't comparable when it comes to their feeling side. Why? Because their Feeling is just in a "supporting role" for their Thinking, whereas Wilde's Thinking was in a supporting role for his Feeling. In my opinion, Wilde was primarily an idealist, not an intellectual, which is something one normally cannot tell about NTs because they would just cease to be NTs. (Likewise, Einstein clearly belonged to intellectuals, not idealists, and Michael Jordan can be hardly seen as anything else but an SP.)
Curiously enough, the only person in my circle of acquaintances who really somewhat reminds me of Wilde is an ENFJ gay male, an aspiring writer with ideas and style very similar to Wilde's and truly impeccable wits.
The main thing that rules out an NT for me, though, is again the fact that Wilde was so comfortable and skillfull in writing about deep emotions.
The Happy Prince is one of the most "feeling" books I've ever read (easily comparable to INFP Andersen's fairy-tales, but more symbolic), and I would have yet to encounter another NT who would be able of this (they usually don't
aspire to do this in the first place). INTJs and ENTPs do come close sometimes, but still, not quite. The whole point of
The Happy Prince is to
provoke strong emotions and subsequent change, which is an NF, specifically NFJ, area. I think that
The Picture of Dorian Gray is primarily based on emotions as well. However, NTs primarily want to provoke
thoughts, feeling tends to be secondary.
