From: "Human Potential & Development."
Split Justification: Development fundamentally involves both our inner landscape (**Internal World**) and our interaction with everything outside us (**External World**). (Ref: Subject-Object Distinction)..
2
From: "Internal World (The Self)"
Split Justification: The Internal World involves both mental processes (**Cognitive Sphere**) and physical experiences (**Somatic Sphere**). (Ref: Mind-Body Distinction)

From: "Somatic Sphere"
Split Justification: The Somatic Sphere encompasses all physical aspects of the self. These can be fundamentally divided based on whether they are directly accessible to conscious awareness and subjective experience (e.g., pain, touch, proprioception) or whether they operate autonomously and beneath the threshold of conscious perception (e.g., heart rate, digestion, cellular metabolism). Every bodily sensation, state, or process falls into one of these two categories, making them mutually exclusive and comprehensively exhaustive.
4
From: "Conscious Somatic Experience"
Split Justification: Conscious somatic experiences can be fundamentally divided based on whether their primary focus is on the body's internal condition, physiological state, or spatial configuration (e.g., hunger, proprioception, pain from an organ, fatigue) or whether they are primarily concerned with the body's interaction, contact, or perception of stimuli from the external environment (e.g., touch, temperature, pressure, pain from an external source). These two categories are mutually exclusive as an experience's primary referent is either internal or external to the body's boundary, and comprehensively exhaustive as all conscious somatic experiences fall into one of these two fundamental domains.
5
From: "Awareness of External Bodily Interactions"
Split Justification: ** All conscious somatic experiences focused on external interactions can be fundamentally categorized by whether the body is actively initiating and controlling the interaction with the environment (e.g., touching, grasping, applying pressure, manipulating objects) or whether it is passively receiving stimuli or impacts from the external environment (e.g., being touched, feeling ambient temperature, experiencing external pressure or impact). This distinction precisely separates experiences by the primary locus of agency in the interaction, making the categories mutually exclusive, and together they cover the entire scope of awareness of external bodily interactions, thus being comprehensively exhaustive.
6
From: "Awareness of Passive External Bodily Reception"
Split Justification: All conscious experiences of passive external bodily reception can be fundamentally divided based on whether they arise from direct physical forces causing deformation of the body's surface (e.g., touch, pressure, vibration) or from environmental properties (temperature, chemical presence) and potentially harmful stimuli (pain from external sources, regardless of its primary cause). This creates two categories that are mutually exclusive in their primary sensory modality and comprehensively exhaustive for all such passive receptions.
7
From: "Awareness of External Mechanical Contact"
Split Justification: All conscious experiences of external mechanical contact can be fundamentally distinguished by whether the mechanical force or deformation is relatively constant and steady over the period of perception (e.g., sustained pressure, an object resting on the skin), or if it involves variability, movement, or change in intensity, frequency, or location over time (e.g., vibration, brushing, light taps, friction). These categories are mutually exclusive, as an external mechanical contact is either perceived as steady or as changing, and together they comprehensively cover all forms of awareness of external mechanical contact.
8
From: "Awareness of Steady External Mechanical Contact"
Split Justification: All conscious experiences of steady external mechanical contact are fundamentally distinguished by whether the contact is perceived as occurring at a distinct, confined point or very small area on the body's surface, or as being spread across a larger, more diffuse region. This dichotomy precisely categorizes the perceived spatial extent of the steady external mechanical interaction, making the categories mutually exclusive, and comprehensively exhaustive as all such experiences fall into one of these two fundamental spatial configurations.
9
From: "Awareness of Localized Steady External Mechanical Contact"
Split Justification: ** All conscious experiences of localized steady external mechanical contact are fundamentally distinguished by whether the mechanical force applied is primarily perpendicular to the body's surface, causing indentation (normal pressure), or primarily parallel to the body's surface, causing distortion or stretching of the skin (tangential shear). These two categories are mutually exclusive as a steady localized force is either perceived as acting predominantly normally or tangentially to the surface, and they are comprehensively exhaustive as all mechanical forces on a surface can be decomposed into these two fundamental components.
10
From: "Awareness of Localized Steady Normal Pressure"
Split Justification: ** All conscious experiences of localized steady normal pressure are fundamentally distinguished by whether the perceived intensity of the pressure triggers a sensation of potential tissue damage or harm, classifying it as noxious (painful), or if it remains below this threshold, perceived as non-noxious pressure. These two categories are mutually exclusive, as a specific sensation of localized steady normal pressure is either experienced as noxious or non-noxious, and comprehensively exhaustive, as all such conscious experiences fall into one of these two fundamental qualitative outcomes.
11
From: "Awareness of Noxious Localized Steady Normal Pressure"
Split Justification: ** All conscious experiences of noxious localized steady normal pressure are fundamentally distinguished by their qualitative character: whether the pain is perceived as sharp, pricking, or piercing, indicating a precise and acute sensation, or as dull, aching, or throbbing, indicating a more diffuse, sustained, or deeper sensation, even within the localized area. These two categories represent primary qualitative differences in the perception of mechanical noxious stimuli, often associated with distinct neural pathways (e.g., Aδ vs. C fibers), making them mutually exclusive and comprehensively exhaustive for describing the fundamental quality of this specific type of pain.
12
From: "Awareness of Dull/Aching Localized Steady Normal Pressure"
Split Justification: All conscious experiences of dull/aching localized steady normal pressure are fundamentally distinguished by their perceived temporal character: whether the sensation itself exhibits a rhythmic pulsation or throbbing quality, or whether it is experienced as a continuous, unvarying ache. This distinction addresses a fundamental qualitative difference in the temporal presentation of the pain, even when originating from a steady external stimulus, and directly reflects the 'throbbing' characteristic previously grouped with 'dull/aching'. These two categories are mutually exclusive as a dull/aching sensation is either perceived as pulsating or constant, and comprehensively exhaustive as all such experiences fall into one of these two fundamental temporal perceptions.
