The process of perception begins with an object in the real world, known as the distal stimulus or distal object. By means of light, sound, or another physical process, the object stimulates the body’s sensory organs. These sensory organs transform the input energy into neural activity—a process called transduction. This raw pattern of neural activity is called the proximal stimulus. These neural signals are then transmitted to the brain and processed. The resulting mental re-creation of the distal stimulus is the percept.
To explain the process of perception, an example could be an ordinary shoe. The shoe itself is the distal stimulus. When light from the shoe enters a person’s eye and stimulates the retina, that stimulation is the proximal stimulus. The image of the shoe reconstructed by the brain of the person is the percept.
-Wikipedia, Perception
Regardless of what anyone believes about the nature of reality or the world, it is an irrefutable fact that existence—as it actually and constantly appears—appears only in the form of someone experiencing and the things that someone experiences.
This is it; bada bing, bada boop; no two ways around it, no dancing around it, this is the form in which existence manifests. Existence does not appear in any other form.
“Someone” or a person, moreover, consists or is composed of the material substance of that person’s experience, i.e. that person’s experience is a substance: it is the substance of that particular person and that which that person experiences as opposed to the experience of any being that is not that person.
Everything you see around you, a desk; the sky; street signs, the bodies of every person in your visual field; every blade of grass seen on the side of the highway as you travel from one city to another; each of these are made up of your subjective experience as opposed to something that is not/is other than subjective experience, and the existence of their “you-absent” (through unconsciousness or death) or “you-independent” doppelgangers are actually entirely fictional entities made up by one’s consciousness in the form of thought in the form of that thought thinking up the idea of “you-independent” doppelgangers of objects, environments, and people that come from you and that are actually made up of you, that is, your subjective experience.
When you think about it, everything said above is actually a logical consequence of the belief that the brain creates consciousness and that consciousness ceases to exist when the brain ceases to function.
For those like yours truly that do not believe brains create consciousness or that consciousness ceases to exist at death, the above is the most simple induction about the nature of reality: that the only thing that exists is consciousness, distal objects and stimuli do not exist, and existence can only take the form of persons.
For as far as existence indicates itself in terms of the invariant nature in which it appears…
…All is Percept, and Distal Objects are imaginary fictions.
Even if they existed, they could not have any rational relation which subjective experience if they are not made up of subjective experience and more importantly, if distal objects are not made up of/can magically transform into the subjective experience of a particular person as opposed to any other being that is not that person.
