APPENDIX D: GLOSSARY OF 500 KEY CONCEPTS ACROSS ALL SUBJECTS

PART 1: FOUNDATIONAL PHILOSOPHY & EPISTEMOLOGY (How We Know)

1. Epistemology – The study of knowledge: what justifies belief, how we know what we claim to know, and the difference between opinion and truth.

2. Ontology – The study of being and reality: what exists, what it means for something to exist, and the categories of existence.

3. Axiology – The study of values: ethics (what is good) and aesthetics (what is beautiful).

4. Justified True Belief – The classic (but flawed) definition of knowledge: you know something if you believe it, it is true, and you have good reasons for it.

5. Skepticism – The position that certain knowledge is impossible or that we should doubt all claims until proven otherwise.

6. Empiricism – The theory that all knowledge comes from sensory experience, not from innate ideas or pure reason.

7. Rationalism – The theory that reason, not sensory experience, is the primary source of knowledge.

8. A Priori – Knowledge that is independent of experience, such as “all bachelors are unmarried.”

9. A Posteriori – Knowledge that depends on experience, such as “the sky is blue.”

10. The Regress Problem – The infinite chain of “how do you know that?” – every justification seems to require another justification, leading to infinite regress, circularity, or an arbitrary stop.

11. Foundationalism – The solution to the regress problem that says some beliefs (self‑evident or basic) do not need further justification.

12. Coherentism – The solution to the regress problem that says beliefs are justified by how well they fit together in a web, not by basic foundations.

13. Phenomenology – The philosophical method that studies conscious experience from the first‑person perspective, suspending assumptions about an external world.

14. Hermeneutics – The theory and practice of interpretation, especially of texts, symbols, and human actions.

15. Paradigm – In Kuhn’s philosophy of science, a shared set of assumptions, methods, and exemplars that defines normal science within a community.

16. Incommensurability – The idea that competing scientific paradigms are so different that they cannot be directly compared or translated into each other.

17. Verstehen – The interpretive understanding of human action from the actor’s point of view, central to Weber’s sociology.

18. Intersubjectivity – Shared understanding between multiple subjects; knowledge that is neither purely objective nor purely private.

19. The Hermeneutic Circle – The paradox that we understand a text’s parts only in light of the whole, but the whole only in light of the parts – a circular but productive process.

20. Reflexivity – The capacity of a system (or a researcher) to turn back on itself; the fact that theories of society are produced within society.

24. Syllogism – A three‑part logical argument consisting of a major premise, a minor premise, and a conclusion.

25. Modus Ponens – A valid deductive form: if P implies Q, and P is true, then Q is true.

26. Modus Tollens – A valid deductive form: if P implies Q, and Q is false, then P is false.

33. Confirmation Bias – The tendency to seek out and interpret information that confirms existing beliefs while ignoring disconfirming evidence.
