Or is everyone else acting like us and just doing a lot of listening? Maybe we need to be louder. Maybe we need to send more messages out there.

Are our brains capable of comprehending the cosmos in all of its complexity and splendor?.

An abandoned orphan's dream opened the way to understanding the architecture of thought.
