The nematode enters the insect's mouth, anus, or spiracle and migrates into the hemocoel. There the nematode injects millions of bacterial symbionts from its own intestine into the insect's circulatory system. These bacteria, though harmless to the nematode, kill the insect within hours.

And yet I think that the Full House model does teach us to treasure variety for its own sake—for tough reasons of evolutionary theory and nature's ontology, and not from a lamentable failure of thought that accepts all beliefs on the absurd rationale that disagreement must imply disrespect. Excellence is a range of differences, not a spot. Each location on the range can be occupied by an excellent or an inadequate representative—and we must struggle for excellence at each of these varied locations. In a society driven, often unconsciously, to impose a uniform mediocrity upon a former richness of excellence—where McDonald's drives out the local diner, and the mega-Stop & Shop eliminates the corner Mom and Pop—an understanding and defense of full ranges as natural reality might help to stem the tide and preserve the rich raw material of any evolving system: variation itself.

Phony psychics like Uri Geller have had particular success in bamboozling scientists with ordinary stage magic, because only scientists are arrogant enough to think that they always observe with rigorous and objective scrutiny, and therefore could never be so fooled—while ordinary mortals know perfectly well that good performers can always find a way to trick people.
