thought laboratory
Thought Laboratory is a collection of interactive experiments built on canonical philosophy. Not essays to read. Not arguments to follow at arm's length. Positions to take, under conditions that make taking them difficult.
Each experiment is drawn from a thought experiment that changed how philosophers reason — and rebuilt so that you have to reason through it yourself.

Thirty statements. Two choices each. The test does not judge whether your beliefs are right or wrong — it finds where they contradict each other.
Most people are surprised by how many tensions their beliefs contain. The question is not whether you are consistent — but where you are not.
