When one is gripped by excruciating physical pain, one is always shock — David Pearce (philosopher)

"Too many of our preferences reflect nasty behaviours and states of mind that were genetically adaptive in the ancestral environment. Instead, wouldnt it be better if we rewrote our own corrupt code?"

"Confusion of sapience with sentience can be ethically catastrophic."

"Suffering exists only because it was good for our genes. Conditionally-activated negative emotions were fitness-enhancing in the ancestral environment. In the current era, apologists for mental pain are serving as the innocent mouthpieces of the nasty bits of code which spawned them."

"The reason for sketching whats technically feasible with the tools of synthetic biology is that only after human complicity in the persistence of suffering in the biosphere is acknowledged can we hope to have an informed socio-political debate on the morality of its perpetuation. No serious ethical discussion of free-living animal suffering can begin in the absence of recognition of human responsibility for nonhuman well-being."

"[L]ike nonhuman animals in human factory farms, free-living nonhumans who are starving - or being disembowelled, asphyxiated or eaten alive - cannot console themselves by chanting the Four Noble Truths of Buddhism. The moral case for helping other sentient beings, regardless or race or species, does not rest on the distress their plight does (or doesnt) cause spectators."

"Today, empathetic intelligence entails sharing the sorrows of other sentient beings. In our posthuman future, will empathy consist entirely in sharing each others joys?"
