"The juvenile sea squirt wanders through the sea searching for a suitable rock or hunk of coral to cling to and make its home for life. For this task, it has a rudimentary nervous system. When it finds its spot and takes root, it doesn't need its brain anymore so it eats it!"

This quote by Daniel Dennett speaks with the idea of purpose and the power of adjustment. The juvenile sea squirt is searching for a location to call house, and it has a simple nerve system to help it in its search. Once it discovers the perfect spot, it no longer requires its brain, so it consumes it. This is a powerful metaphor for how we, as people, can adjust to our environment and find our function. We can use our brains to help us find our location on the planet, and once we do, we can dispose of the parts of ourselves that no longer serve us. This quote speaks with the concept that we can all discover our place in the world, which we can use our brains to assist us get there.
