It's easy to support the status quo if one is not another of its victims. - David Pearce

More controversially, technology can accelerate the transition from harming to helping free-living sentient beings: mankind's fitfully expanding "circle of compassion". The civilising process needn't be species-specific but instead extend to free-living dwellers in tomorrow's wildlife parks. Every cubic metre of the biosphere will soon be computationally accessible to surveillance, micro-management and control. Fertility regulation via immunocontraception can replace Darwinian ecosystems governed by starvation and predation. Any species of obligate carnivore we choose to preserve can be genetically and behaviourally tweaked into harmlessness. Asphyxiation, disembowelling, and agonies of being eaten alive can pass into the dustbin of history.

Human intuitions are systematically biased. Evolutionary psychology explains how our moral intuitions and the rationalisations they spawn have been shaped by millennia of natural selection to maximise the inclusive fitness of our genes, not to track the welfare of other sentient beings impartially conceived. Many human cultures have found nothing intuitively wrong with aggressive warfare, slavery, wife-beating, infanticide or female genital mutilation. Ultimately, folk morality is a doomed enterprise as hopeless as folk physics. A mature posthuman ethics, I'd argue, must be committed to the well-being of all sentient life; and mature posthuman technology offers the means to deliver that commitment.

Confusion of sapience with sentience can be ethically catastrophic.
