The Spider in the Urinal This one’s reminiscent of Plato’s Cave, another classic (and disturbing) thought experiment. Proposed by Thomas Nagel in his essay, “Birth, Death, and the Meaning of Life,” it addresses issues of non-interference and the meaningfulness of life. He got the idea when he noticed a sad little spider living in a urinal in the men’s bathroom at Princeton where he was teaching. The spider appeared to have an awful life, constantly getting peed on, and “he didn’t seem to like it.” He continues: Gradually our encounters began to oppress me. Of course it might be his natural habitat, but because he was trapped by the smooth porcelain overhang, there was no way for him to get out even if he wanted to, and no way to tell whether he wanted to...So one day toward the end of the term I took a paper towel from the wall dispenser and extended it to him. His legs grasped the end of the towel and I lifted him out and deposited him on the tile floor. He just sat there, not moving a muscle. I nudged him slightly with the towel, but nothing happened . . . . I left, but when I came back two hours later he hadnt moved. The next day I found him in the same place, his legs shriveled in that way characteristic of dead spiders. His corpse stayed there for a week, until they finally swept the floor. Nagel acted out of empathy, assuming that the spider would fare better — and perhaps even enjoy life — outside of its normal existence. But the exact opposite happened. In the end, he did the spider no good. This thought experiment forces us to consider the quality and meaningfulness of not just animal lives, but our own as well. How can we ever know what anyone really wants? And do our lives actually do us any good? It also forces us to question our policies of intervention. Despite our best intentions, interference can sometimes inflict unanticipated harm. It’s a lesson embedded within Star Trek’s Prime Directive — but as the Trolley Problem illustrated, sometimes inaction can be morally problematic.
