Origin Path

1
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)..
➔ "Internal World (The Self)" (W1)
"External World (Interaction)" (W2)
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)
➔ "Cognitive Sphere" (W3)
"Somatic Sphere" (W5)
3
From: "Cognitive Sphere"
Split Justification: Cognition operates via deliberate, logical steps (**Analytical Processing**) and faster, intuitive pattern-matching (**Intuitive/Associative Processing**). (Ref: Dual Process Theory)
➔ "Analytical Processing" (W7)
"Intuitive/Associative Processing" (W11)
4
From: "Analytical Processing"
Split Justification: Analytical thought engages distinct symbolic systems: abstract logic and mathematics (**Quantitative/Logical Reasoning**) versus structured language (**Linguistic/Verbal Reasoning**).
➔ "Quantitative/Logical Reasoning" (W15)
"Linguistic/Verbal Reasoning" (W23)
5
From: "Quantitative/Logical Reasoning"
Split Justification: Logical reasoning can be strictly formal following rules of inference (**Deductive Proof**) or drawing general conclusions from specific examples (**Inductive Reasoning Case Study**). (L5 Split)
➔ "Deductive Proof." (W31)
"Inductive Reasoning Case Study" (W47)
6
From: "Deductive Proof."
Split Justification: Deductive systems can be analyzed based on the relationship between whole statements (**Propositional Logic**) or the properties of objects and their relations (**Predicate Logic**). (L6 Split)
➔ "Propositional Logic" (W63)
"Predicate Logic" (W95)
7
From: "Propositional Logic"
Split Justification: Propositional logic involves determining the validity of arguments (**Truth Table Construction**) and applying rules of inference (**Using Modus Ponens/Tollens**).
➔ "Truth Table Construction" (W127)
"Using Modus Ponens/Tollens" (W191)
8
From: "Truth Table Construction"
Split Justification: The process is divided into defining the table's structural framework (Table Structuring) and the subsequent, row-by-row calculation of truth values based on logical operators (Truth Value Computation).
"Table Structuring" (W255)
➔ "Truth Value Computation" (W383)
9
From: "Truth Value Computation"
Split Justification: Truth value computation requires first identifying the values of the simplest statements (Atomic Proposition Evaluation) and then combining them using the rules of logical operators (Logical Connective Application).
➔ "Atomic Proposition Evaluation" (W639)
"Logical Connective Application" (W895)
10
From: "Atomic Proposition Evaluation"
Split Justification: This split differentiates between determining a proposition's truth value from external observation (Empirical Verification) versus accepting a value given by the rules of a formal system (Stipulated Assignment).
➔ "Empirical Verification" (W1151)
"Stipulated Assignment" (W1663)
11
From: "Empirical Verification"
Split Justification: This split distinguishes between verification through one's own firsthand sensory experience (Direct Observation) and verification through an intermediary, such as instrumentation, testimony, or records (Indirect Confirmation).
"Direct Observation" (W2175)
➔ "Indirect Confirmation" (W3199)
12
From: "Indirect Confirmation"
Split Justification: Indirect confirmation is achieved either by demonstrating that the opposite position leads to an empirical or logical absurdity (Proof by Contradiction) or by validating the logically equivalent inverse conditional statement (Proof by Contrapositive).
➔ "Proof by Contradiction" (W5247)
"Proof by Contrapositive" (W7295)
