Each human being has the right to seek out joy, joy being understood as something which makes one content - not necessarily that which makes others content.
PAIN was no longer a cause of suffering, but a source of pleasure, Because they were redeeming humanity from its sins. Pain becomes joy, the meaning of life, pleasure.
There is little that separates humans from other sentient beings - we all feel joy, we all deeply crave to be alive and to live freely, and we all share this planet together.
