The If Machine

How It Works

A typical session starts with the parent reading a 2-5 minute story or presenting a 'thought experiment' (e.g., 'The Ring of Gyges'). Following the reading, the parent uses the provided 'Question Quadrant' to guide a discussion that tests the child's logic and definitions. Sessions usually last 20 to 40 minutes depending on the child's engagement. There are no worksheets; the focus is entirely on verbal reasoning, listening, and articulating complex ideas.

Switching to This?

No placement test is required as the inquiries are designed to be 'age-indifferent.' Families typically start at the beginning of the book and move through the stories chronologically, though you can easily jump to topics that interest your child. It is very easy to start mid-year as a supplement.

How This Compares

Philosophy for Kids (David White) uses a similar inquiry-based approach but is slightly more academic and structured. The Critical Thinking Co.'s 'Building Thinking Skills' is workbook-heavy and focuses more on puzzles than philosophical dialogue. 'The Philosophy Shop' (also by Worley) is a more advanced companion with more varied prompts.
