When we perceive something new for the first time we cannot really perceive it because we lack the appropriate structure that allows us to perceive it. Our brain is like a lock maker that makes a lock whenever a key is deemed interesting enough. But when a key—for example, a new poem, or a new species of animal—is first met, there is no lock yet ready for such a key. Or to be precise, the key is not even a key since it does not open anything yet. It is a potential key. However, the encounter between the brain and this potential key triggers the making of a lock. The next time we meet or perceive the object/key it will open the lock prepared for it in the brain.
