maybe that's too extreme of an example, but it illustrates the point that the hedonist notion of good and bad is vastly ambiguous and can lead to undesirable situations, most notably in cases where people try to optimize for the afterlife, but also in varying degrees in other cases. so i think it ultimately it fails in practice as a moral philosophy.
I also think hedonism tends to stigmatize pain to an impractical degree. i think experiencing and accepting pain is an important part of life, not because it leads to greater pleasure, but because pain is a part of the human condition and there's value in observing it and recognizing its importance. in regards to art, there can't be catharsis without pain, so it doesn't make sense to me to say that pleasure is somehow better than pain in that sense. i think pain and pleasure are two sides of the same coin.
i don't know. maybe i'm just crazy
