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: "External World (Interaction)"
Split Justification: All external interactions fundamentally involve either other human beings (social, cultural, relational, political) or the non-human aspects of existence (physical environment, objects, technology, natural world). This dichotomy is mutually exclusive and comprehensively exhaustive.
3
From: "Interaction with the Non-Human World"
Split Justification: All human interaction with the non-human world fundamentally involves either the cognitive process of seeking knowledge, meaning, or appreciation from it (e.g., science, observation, art), or the active, practical process of physically altering, shaping, or making use of it for various purposes (e.g., technology, engineering, resource management). These two modes represent distinct primary intentions and outcomes, yet together comprehensively cover the full scope of how humans engage with the non-human realm.
4
From: "Modifying and Utilizing the Non-Human World"
Split Justification: This dichotomy fundamentally separates human activities within the "Modifying and Utilizing the Non-Human World" into two exhaustive and mutually exclusive categories. The first focuses on directly altering, extracting from, cultivating, and managing the planet's inherent geological, biological, and energetic systems (e.g., agriculture, mining, direct energy harnessing, water management). The second focuses on the design, construction, manufacturing, and operation of complex artificial systems, technologies, and built environments that human intelligence creates from these processed natural elements (e.g., civil engineering, manufacturing, software development, robotics, power grids). Together, these two categories cover the full spectrum of how humans actively reshape and leverage the non-human realm.
5
From: "Creating and Advancing Human-Engineered Superstructures"
Split Justification: ** This dichotomy fundamentally separates human-engineered superstructures based on their primary mode of existence and interaction. The first category encompasses all tangible, material structures, machines, and physical networks built by humans. The second covers all intangible, computational, and data-based architectures, algorithms, and virtual environments that operate within the digital realm. Together, these two categories comprehensively cover the full spectrum of artificial systems and environments humans create, and they are mutually exclusive in their primary manifestation.
6
From: "Engineered Physical Constructs and Infrastructures"
Split Justification: This dichotomy distinguishes between the large-scale, often fixed, and interconnected physical systems that form the fundamental backbone and enabling environment for human activity and society (e.g., transportation networks, utility grids, major public facilities), versus the more discrete, often mobile, and purpose-specific physical constructs and objects designed for direct operational use, individual function, or localized habitation within or upon these foundational systems (e.g., vehicles, tools, machinery, appliances, individual dwellings).
7
From: "Foundational Infrastructure Systems"
Split Justification: This dichotomy fundamentally separates foundational infrastructure systems based on their primary function. The first category encompasses systems dedicated to the provision, distribution, and treatment of essential physical resources (e.g., energy, water) and core services (e.g., waste management, physical communication backbones). The second category comprises systems primarily designed to facilitate the physical movement of people and goods, and to structure broad physical access and connectivity within human settlements and across regions (e.g., transportation networks, public access infrastructure). These two functions are distinct, mutually exclusive, and together comprehensively cover the scope of foundational infrastructure.
8
From: "Mobility and Spatial Access Systems"
Split Justification: This dichotomy fundamentally separates mobility and spatial access systems based on their primary purpose: facilitating the physical movement and access of human beings versus facilitating the transportation and distribution of physical goods and resources. These distinct primary functions lead to differing infrastructure design, operational priorities, and network configurations, yet together they comprehensively cover the entire scope of engineered systems enabling mobility and spatial access.
9
From: "Human Mobility and Access Systems"
Split Justification: This dichotomy differentiates human mobility and access systems based on the typical geographical range and purpose of the movement they facilitate. "Local Human Mobility Systems" are designed for daily commutes, access within communities, and movement within confined geographical areas (e.g., pedestrian networks, urban public transport, building access infrastructure). "Long-Distance Human Mobility Systems" are engineered to facilitate travel between distinct cities, regions, or countries (e.g., intercity highway networks, high-speed rail, commercial aviation infrastructure). This fundamental distinction leads to different infrastructure designs, operational requirements, and planning considerations, yet together these two categories comprehensively cover the entire scope of human mobility and access systems.
10
From: "Local Human Mobility Systems"
Split Justification: This dichotomy fundamentally separates local human mobility systems based on their primary mode of supporting movement. The first category encompasses infrastructure designed to facilitate direct human locomotion (e.g., walking, cycling) and integral movement within built structures (e.g., elevators, escalators). The second category comprises infrastructure engineered to support the movement of people via distinct, often powered vehicles operating on dedicated or shared networks (e.g., roads for private cars, public transport tracks and lanes). These two categories represent distinct design principles, operational characteristics, and typical user interfaces for local movement, yet together they comprehensively cover the full scope of local human mobility systems.
11
From: "Infrastructure for Vehicular Local Mobility"
Split Justification: This dichotomy fundamentally separates infrastructure for vehicular local mobility based on its physical design and operational principle. The first category encompasses systems that provide a physically constrained, predefined path for vehicles (e.g., rails, dedicated guideways, enclosed tunnels). The second category comprises systems that facilitate flexible, shared movement of vehicles over open surfaces and networks (e.g., general-purpose roads, streets, parking facilities). This distinction is mutually exclusive, as a piece of infrastructure is either fixed or open in its primary design, and together these two categories comprehensively cover the full scope of local vehicular mobility infrastructure.
12
From: "Fixed-Guideway and Tracked Infrastructure for Local Mobility"
Split Justification: This dichotomy fundamentally separates fixed-guideway and tracked infrastructure based on its spatial relationship with the surrounding environment and other modes of transport. The first category encompasses infrastructure designed with an exclusive right-of-way, physically separated from other vehicular traffic and pedestrian flow (e.g., subways, elevated rail, monorails). The second category comprises infrastructure that shares space or is integrated within the existing urban street network, often interacting directly with road traffic, pedestrians, or adjacent land uses (e.g., streetcars, light rail operating at-grade, tram systems). This distinction is mutually exclusive in design and operational principle, and together these two categories comprehensively cover the full scope of fixed-guideway and tracked infrastructure for local mobility.
