had laid her eggs into a silken egg sac the size of a Milk Dud and then protected that sac vigilantly, keeping it warm, fending off any threats, as black widow mothers do. While she was waiting for the eggs to come to term, she would have been particularly edgy, particularly unforgiving, and my hand would have been in particular danger each time I reached for a fallen pencil. Then the great day arrived. The spiderlings hatched from their individual eggs, chewed their way out of the sac, and started crawling, brothers and sisters together, up toward the orange tensor lamp that was giving off heat and light on the desk of the nitwit who was their landlord.
By the time I stumbled in, fifty or sixty of them had reached the lampshade and rappelled back down on dainty silk lines, leaving a net of gossamer rigging between the lamp and the Darwin book (it happened to be an old edition of Insectivorous Plants, with marbled endpapers) that sat on the desk. Somedozen others had already managed dispersal flights, letting out strands of buoyant silk and ballooning away on rising air, as spiderlings doâin this case dispersing as far as the bookshelves. It was too late for one man to face one spider with just a pickle jar and an index card and his two shaky hands. By now I was proprietor of a highly successful black widow hatchery.
And the question was, How should a human behave toward the members of other living species?

The Jain religion of India has a strong teaching on that question. The Sanskrit word is ahimsa, generally rendered in English as ânoninjuryâ or the imperative âdo no harm.â Ahimsa is the ethical centerpiece of Jainism, an absolute stricture against the killing of living beingsâ any living beingsâand it led the traditional Jains to some extreme forms of observance. A rigorously devout Jain would burn no candles or lights, for instance, if there was danger a moth might fly into them. The Jain would light no fire for heating or cooking, again because it might cause the death of insects. He would cover his mouth and nose with a cloth mask, so as not to inhale any gnats. He would refrain from cutting his hair, on grounds that the lice hiding in there might be gruesomely injured by the scissors. He could not plow a field, for fear of mutilating worms. He could not work as a carpenter or a mason, with all that dangerous sawing and crunching, nor could he engage in most types of industrial production. Consequently the traditional Jains formed a distinct socioeconomic class, composed almost entirely of monks and merchants. Their ethical canon was not without what you and I might take to be glaring contradictions (vegetarianism was sanctioned, plants as usual getting dismissive treatment in the matter of rights to life), but at least they took it seriously. They lived by it. They tried their best to do no harm.
And this in a country, remember, where 10,000 humans died every year from snakebite, almost a million more from malariacarried in the bites of mosquitoes. The black widow spider, compared to those fellow creatures, seems a harmless and innocent beast.
But personally I hold no brief for ahimsa, because I donât delude myself that itâs even theoretically (let alone practically) possible. The basic processes of animal life, human or otherwise, do necessarily entail a fair bit of ruthless squashing and gobbling. Plants can sustain themselves on no more than sunlight and beauty and a hydroponic dietâbut not we animals. Iâve only mentioned this Jainist ideal to suggest the range of possible viewpoints.
Modern philosophers of the âanimal liberationâ movement, most notably Peter Singer and Tom Regan, have proposed some other interesting answers to the same question. So have writers like Barry Lopez and Eugene Linden, and (by their example, as well as by their work) scientists like Jane Goodall and John Lilly and Dian
