Epistemic justification theories

I. Foundations of Reasoning

Core types of reasoning

  1. What are the core types of reasoning, and how do they differ in structure, certainty, and use?

    [Philosophical anchor: Humans seek truth, but operate under constraints of time, knowledge, and uncertainty. These reasoning modes are tools for navigating epistemic limits.]

  2. What distinguishes deductive, inductive, and abductive reasoning in mechanism and reliability?

    [Deduction aims for certainty; induction and abduction trade certainty for applicability. Philosophers debate whether induction is rationally justifiable at all — see Hume’s problem of induction.]

  3. What other reasoning modes exist (e.g. analogical, Bayesian, reductive), and when are they used?

    [These modes reflect the fact that real-world reasoning often blends formal logic with pragmatism — a key tension in philosophy of mind and AI.]

  4. What is the relationship between truth, validity, soundness, and belief in a logical argument?

    [Raises foundational epistemological questions: Can we ever know truth? Must valid reasoning lead to true beliefs?]

  5. What roles do heuristics, axioms, and first principles play in human and formal reasoning systems?

    [Explores the origins of reasoning. Is it innate, constructed, or system-relative? What do we assume without proof, and why?]

II. Structure and Mechanics of Arguments

  1. What is the basic structure of an argument, and how are premises and conclusions distinguished?

    [This is the minimal unit of rational discourse. Knowing how arguments work is necessary for evaluating claims.]

  2. How can we determine whether an argument is logically valid or logically sound?

    [Logic is about preserving truth — but soundness demands both form and factual truth. This introduces the link between logic and reality.]

  3. What is a syllogism, and how does it function in formal deductive logic?

    [An early formalism from Aristotle — foundational to Western philosophical logic.]

  4. What are modus ponens and modus tollens, and how are they used in conditional logic?

    [These are the backbone of rigorous reasoning — but are often misapplied in practical settings.]
