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: "Operational Constructs and Discrete Objects"
Split Justification: This dichotomy separates physical constructs based on their primary mode of function. The first category encompasses objects designed for active task performance, transformation, mobility, or direct operational use (e.g., tools, machinery, vehicles, active appliances). The second category includes objects designed primarily to provide a static environment, shelter, storage, or passive containment for living or holding other objects (e.g., individual dwellings, furniture, containers, sheds). These two categories are mutually exclusive in their primary intent and comprehensively cover the scope of operational constructs and discrete objects.
8
From: "Dynamic Operational Devices and Vehicles"
Split Justification: ** This dichotomy fundamentally separates dynamic operational constructs based on their primary mode of function. The first category encompasses physical constructs designed primarily for self-propulsion and the movement of people, goods, or information across distances. The second category includes physical constructs designed primarily to perform active tasks involving transformation, manipulation, or processing of materials, information, or energy, often within a more localized or task-specific operational context, even if they possess internal or limited external movement for task execution. These two categories are mutually exclusive in their primary intent and comprehensively cover the scope of dynamic operational devices and vehicles.
9
From: "Vehicles for Transport and Mobility"
Split Justification: This dichotomy fundamentally separates vehicles based on the primary physical medium in which they operate for transport and mobility. Terrestrial vehicles are designed to operate exclusively or primarily on land surfaces. Aquatic, aerial, and space vehicles are designed to operate in water, air, or the vacuum of space, respectively. These categories are mutually exclusive, as a vehicle primarily operates within one fundamental environmental medium, and comprehensively exhaustive, covering all possible environments for human-engineered transport and mobility.
10
From: "Terrestrial Vehicles"
Split Justification: This dichotomy fundamentally separates terrestrial vehicles based on their primary source of propulsion. The first category includes all vehicles that generate their own power for movement, typically using an onboard engine or motor (e.g., cars, trains, motorcycles, trucks). The second category encompasses vehicles that rely on external muscle power for propulsion, whether from humans or animals (e.g., bicycles, wagons, rickshaws). These two categories are mutually exclusive, as a vehicle either generates its own propulsion or is propelled externally, and comprehensively exhaustive, covering all terrestrial vehicles whose primary function is transport.
11
From: "Human/Animal-Powered Terrestrial Vehicles"
Split Justification: This dichotomy fundamentally separates terrestrial vehicles based on whether their primary external power source is human muscle or animal muscle. These two categories are mutually exclusive, as a vehicle's primary motive force is derived from one or the other, and comprehensively exhaustive, covering all forms of human or animal-powered terrestrial transport.
12
From: "Human-Powered Terrestrial Vehicles"
Split Justification: This dichotomy fundamentally separates human-powered terrestrial vehicles based on the primary bodily posture and mode of interaction the human employs for propulsion. The first category includes vehicles where the human is primarily seated or otherwise substantially supported by the vehicle's structure while generating motion. The second category encompasses vehicles where the human primarily propels it while standing on or within the vehicle, or by actively pushing or pulling the vehicle while walking or running alongside it. These two categories are mutually exclusive in their primary mode of operation and comprehensively exhaustive of human-powered terrestrial vehicles.
