you can't have 'good' without 'bad' as a concept anymore than you can have left without right- they literally define each other.
This is ridiculous. "Left" and "Right" are mutually exclusive, polar opposing ideas. "Good" and "Bad" are
completely relative. In fact, Imagine a sliding scale where "cake" is on the end marked "good", a spanking is on the end marked "bad", and "standing still" appears in the middle of the two. If we take away the "bad" side, there are no more spankings, and you have only the mediocre state of "standing still" and receiving "cake". Now "bad" is "no cake". Done. "Bad" is gone, and there really isn't anything terrible about "standing still". There is no "good" defining "bad", there is only states of relative "good" in that frame of reference.
If we experienced nothing but good and better? Well the closest we can observe is a teenage rock star who has all the health, wealth, fame, fortune, love and adoration from the opposite sex and a brand new Lamborghini- not a care in the world- are they the happiest people on Earth, or do they tend to commit suicide before they turn 21?
One could argue that "fame", exceeding "wealth", less-than-sincere "adoration" and access to fast/luxury cars is not necessarily "good" - especially if a surfeit of said things ends in suicide of the person taking part (this seems sort of self evident, I would think - but maybe those are things you, yourself cherish above all others and believe to be "good"). I mentioned things like spending time doing things you love - spending time with family would be one for me, drawing, coding and doing art for my own, personal video-game projects, crafting archaic-looking objects like staffs, etc. etc. etc. I don't think I would ever tire of a life filled with these things - only the good.
You don't think the piglet would appreciate his comfort far more than he ever did before the factory farm?
Umm... I sort of said that it would in the instance of the piglet stuck in the factory farm. The other thing I meant was that the piglet who wasn't doesn't need to suffer a stint in the factory farm to appreciate his ongoing comfort.
Again Jellyfish experience no pain, grieving, worry, hate, fear- and hence no joy, love, glory, satisfaction either. Few would trade places
This has no bearing on what I am talking about. Again - living a life doing the things you enjoy EXCLUSIVELY. That is what I am talking about. There is no need to bash the jellyfish anymore.
