A durable learning method
Context, clarity, and curiosity.
Serious study can be approachable without being simplistic. Every lesson returns to three repeatable habits.
Read sources closely
Notice genre, audience, purpose, vocabulary, and silence before rushing to conclusions.
Map the context
Place a text among communities, institutions, relationships, conflicts, and the limits of surviving evidence.
Compare voices
Hold continuity and difference together, especially where later labels can flatten earlier diversity.
From the blog
History for the questions you are already asking.
