Notes

The 12 TOK Concepts are the conceptual vocabulary of the course. They orbit the central question: How do we know?

Concept Sample question

What counts as evidence?

How certain is our knowledge?

Can we ever be certain of the truth?

What makes a justified interpretation?

Should we accept knowledge by authority?

What distinguishes a good justification?

What makes an explanation convincing?

What does it mean to be unbiased?

Are some viewpoints more justified?

Does knowledge depend on community?

Is knowledge influenced by ethics?

Where do our duties as knowers end?

These concepts are not independent — they connect in rich ways. The Exhibition asks you to show those connections through real-world objects.
