Our skin is what stands between us and the world.
Fear is danger to your body, but disgust is danger to your soul.
Who you are isn't tied solely to what you say, even though it may feel that way to you now.
Nature neither gives nor expects mercy.
We try to exile ourselves more and more from nature - not always consciously: We build houses; we dismiss nature; nature has to be outside, because we're inside. God forbid something like a cockroach comes inside, or some dust.
We're dabbling in eugenics all the time, breeding ideal crops to replace less aesthetic or nutritious or hardy varieties; leveling forests to graze cattle or erect shopping malls and condos; planting groves of a few familiar trees that homeowners and industries prefer.
