“This smorgasbord of eyes brings with it a dizzying medley of visual Umwelten. Animals might see crisp detail at a distance, or nothing more than blurry blotches of light and shade. They might see perfectly well in what we’d call darkness, or go instantly blind in what we’d call brightness. They might see in what we’d deem slow motion or time-lapse. They might see in two directions at once, or in every direction at once. Their vision might get more or less sensitive over the span of a single day. Their Umwelt might change as they get older. Jakob’s colleague Nate Morehouse has shown that jumping spiders are born with their lifetime’s supply of light-detecting cells, which get bigger and more sensitive with age. “Things would get brighter and brighter,” Morehouse tells me. For a jumping spider, getting older “is like watching the sun rising.”

“There is a wonderful word for this sensory bubble—Umwelt. It was defined and popularized by the Baltic-German zoologist Jakob von Uexküll in 1909. Umwelt comes from the German word for “environment,” but Uexküll didn’t use it simply to refer to an animal’s surroundings. Instead, an Umwelt is specifically the part of those surroundings that an animal can sense and experience—its perceptual world. Like the occupants of our imaginary room, a multitude of creatures could be standing in the same physical space and have completely different Umwelten. A tick, questing for mammalian blood, cares about body heat, the touch of hair, and the odor of butyric acid that emanates from skin. These three things constitute its Umwelt. Trees of green, red roses too, skies of blue, and clouds of white—these are not part of its wonderful world. The tick doesn’t willfully ignore them. It simply cannot sense them and doesn’t know they exist.”

“Normal is often treated as a moral judgment, when it is often simply a statistical matter. The question of what everyone else is doing is less important than the question of what works for the two people in the actual relationship. It matters that everyone’s needs are carefully considered and respected, not that everyone is doing the same thing.”

“I still don’t have any idea what this energy is. This may be the unifying ace call, one I have heard again and again from aces, whether they are sex-favorable or sex-replused, irrespective of their romantic orientation and aesthetic types. Regardless of whether we have sex, we don’t relate to sexuality the way that, seemingly, allos do. We do not center sexuality in our lives.

And, so, aces spend an inordinate amount of time wondering about this energy that other people are detecting, and experiencing, and expressing, that we are not. People think about sex even if they don’t want to? What makes one person sexually attractive on that visceral level and not another? Allos can even be sexually attracted to people they find ugly? What? Like anthropologists after a day of fieldwork, we commiserate about the mysteries of the local culture, even though it is actually the culture that we were born into—just one that, for a long time, had no room for us and our way of being. There is room now.”
