Who this book is for

For students beginning epistemology through a focused question about ordinary speech. Turri’s short study brings a contemporary research programme into reach without requiring formal logic. It is useful alongside a broader knowledge survey, especially for asking how experimental findings can inform philosophical reasoning without automatically deciding it.

Prerequisites

No prior philosophy or cognitive-science training is required. Know the everyday difference between believing something and telling another person that it is true. Be ready to distinguish evidence about people’s judgments from a normative claim.

What it covers

The chapters introduce evidence and argument for a knowledge norm of assertion, explore extensions and connections, consider objections and replies, and discuss future research. The book combines philosophical discussion with psychological and biological considerations. Its central proposal gives readers a concrete claim to assess: what condition should govern an assertion and why should that condition be knowledge?

How to use it

Start with the introductory question and write down several ordinary assertion cases. Predict how the proposed norm would assess them before reading the evidence. Separate a study’s reported judgments, the explanation of those judgments and the philosophical conclusion. For one objection, reconstruct both sides and design a new case that could distinguish their predictions. Discuss what an experiment could establish and what would remain an argumentative question.
