"If somebody thinks they're a hedgehog, presumably you just give 'em a mirror and a few pictures of hedgehogs and tell them to sort it out for themselves"

This quote by Douglas Adams is a funny method of stating that people must be enabled to figure out who they are on their own. He is recommending that rather of attempting to inform somebody who they are, it is better to provide them with the tools they need to discover it for themselves. He is indicating that it is not our location to inform someone who they are, however rather to supply them with the resources they need to make that choice for themselves. This quote is a tip that everyone must be permitted to explore and find their own identity without judgement or disturbance from others. It is a pointer that we should appreciate the individual's right to self-determination and enable them to find their own path.
