ThinkAboutit: How Do You Know What You Know?

$12.00

A playful children's philosophy book about knowledge, truth, evidence, perception, and how we know what we know — for curious kids ages 9–12.

How do you know what you know?

Can you trust your five senses?

How do you know when something is true?

Can you be certain about something and still be wrong?

What counts as good evidence?

And how can we tell the difference between knowing something, believing something, and simply thinking something is true?

ThinkAboutIt: How Do You Know What You Know? takes young readers on a philosophical adventure into knowledge, truth, evidence, perception, and reasoning.

Follow Sophia the Wise as she explores some of the biggest questions in philosophy: How do we know what we know? Can our senses be trusted? What makes evidence convincing? And is it possible to know anything for certain?

Along the way, young philosophers meet fascinating thinkers from throughout history and around the world, explore different ideas about knowledge and truth, and try out kid-friendly thought experiments for themselves.

But this isn't a book that simply gives children the answers.

It's an invitation to question, investigate, compare ideas, examine evidence, and think carefully about how we know what we think we know.

With activities, worksheets, conversations, and philosophical experiments, readers get to explore these questions themselves.

Because sometimes the most important question isn't:

“What do you know?”

It's:

“How do you know?”
