I don't think this analogy places the right items on the scales of balance, so to speak.
You don't need to know a desert in order to enjoy the taste of water. But, you do need a dry throat and a feeling of thirst in order to know that you need water, let alone to enjoy it.
point taken, I agree.
Ok, does a baby need to be told how to be happy, filled with joy?
I'm not expert, but from what I know, no. It is an innate emotion.
So why would the absence of 'pain', sadness stop that being an emotion it feels?
If a baby didn't know sadness would it still know joy, happiness..?
Ergo, you do not need to comprehend 'the negative', to enjoy the positive.
I hope my clumsy attempts to put my point across are okay -
I don't posses your education in philosophy, I think.
But my points are still valid, as I see.
