Why expect a false theory of the world, i.e. classical physics, to yield a true account of consciousness? - David Pearce

... our descendants may recognize that we are the sociopathic emotional primitives in the grip of an affective psychosis. Jealousy, envy, resentment, ridicule, hate, anger, disgust, spite, contempt, schadenfreude and a whole gamut of nameless but mean-spirited states we undergo each day are a toxic legacy of our Darwinian past. More commonly, perhaps, our genetic make-up ensures we simply feel indifference to the plight of all but a handful of significant others in our lives. Right now, for instance, one knows dimly at some level that there is frightful and preventable suffering in the world. Yet most of us feel no overpowering moral urgency to do anything about it.

The functional regions of the brain which subserve physical agony, the "pain centres", and the mainly limbic substrates of emotion, appear in phylogenetic terms to be remarkably constant in the vertebrate line. The neural pathways involving serotonin, the periaquaductal grey matter, bradykinin, dynorphin, ATP receptors, the major opioid families, substance P etc all existed long before hominids walked the earth. Not merely is the biochemistry of suffering disturbingly similar where not effectively type-identical across a wide spectrum of vertebrate (and even some invertebrate) species. It is at least possible that members of any species whose members have more pain cells exhibiting greater synaptic density than humans sometimes suffer more atrociously than we do, whatever their notional "intelligence".

Humans are prone to status quo bias. So let's do a thought-experiment. Imagine we stumble across an advanced civilisation that has abolished predation, disease, famine, and all the horrors of primitive Darwinian life. The descendants of archaic lifeforms flourish unmolested in their wildlife parks – free living, but not "wild". Should we urge scrapping their regime of compassionate stewardship of the living world – and a return to asphyxiation, disembowelling and being eaten alive? Or is a happy biosphere best conserved intact?
