Voice: Fictional character · Lord Henry Wotton
Definitions clarify ideas but can also narrow them, especially when a label is treated as the complete reality of a person or experience.

“The world is my idea.”

“I neither know nor think that I know.”
Voice: Dialogue speaker · Socrates
Socrates locates a small advantage in recognizing the boundary of his own knowledge: uncertainty is intellectually healthier than possessing the same ignorance while mistaking it for wisdom.
Source note: Plato, Apology, Benjamin Jowett translation, Project Gutenberg #1656. Socrates says this after examining a politician whom others considered wise; the wording is dialogue speech attributed to Socrates within Plato’s work, not a claim that Socrates knew literally nothing.
