Core Concepts in Logic, Cognitive Bias, and Epistemology
Logic and Argumentation
An argument is deductively valid when it is impossible for its conclusion to be false if its premises are true. If the premises provide complete support for the conclusion, the argument is valid, regardless of whether the premises themselves are true.
Common Logical Forms
- Modus Ponens (Affirming the Antecedent): If P, then Q. P is true; therefore, Q is true.

Linguistic Development: From Old English to Modern English
Linguistic Change and Classification
Linguistic change involves the substitution of one linguistic element for another. All languages are constantly changing in a gradual process that speakers often perceive as a “decline.”
Classification Methods
- Genealogical: Traces ancestry (e.g., Germanic → Anglo-Frisian → OE → English). Sister languages share an origin, while cognates share an ancestor (father/pater). False friends are similar words with different meanings.
- Typological: Focuses on how languages
