I just asked my rabbits this question for you. Do they count as who?<p>They continued chomping down celery tops and coriander.<p>One of them likes to watch planes. It sits on its hutch in the afternoon watching planes from a local airport fly away, more interested in them on days when the wind's blowing such that when nearby they're taking off rather than days when the wind means they're approaching. The other one doesn't care for planes, but stamps whenever a wasp's nearby. This second one also likes to observe, then crush with a front paw, any ants it comes across or that come across it.<p>Remarkably human behaviour, though I know not what they think. Is it curiosity. Is it fear? Is something in-built and there is no 'thinking'? And what of us? Do we really comprehend? An Area51 alien is to me as a flying celery-rabbit on a magical boat with radish tops for wings is perhaps to these rabbits, if they've ever thought to imagine. They do seem to dream. That is, it's completely within bounds of their known reality. As outlandish as the very real, lived, imaginations of a schizophrenic delusion may be, and my observing it based on my 'norms', it's still somewhat based on the individual's experience, or imagination, of their reality, their experiences.<p>Perhaps there are aliens. Perhaps they exist in differing dimensions. Perhaps they exist as stars blinking to one another, perhaps they exist in my underpants or in fact are my underpants, what do I know, we are all in our (bounded?, there is always a bound...) existence, as Spinoza pointed out, of "Substance, its attributes, and modes".
