How does it feel to be human? A human you say? It feels like emptiness through knowledge. Brains within the heads of man retain facts and fiction, eating the information that makes it hungry. Knowledge is a powerful tool, the one that creates the others. The hammer and nail create the house, yet the man creates the hammer. What is the price of thought? What is the drawback to acceleration of growth? Knowledge. Knowledge is its own downfall. The more one knows, the less he knows. The more one searches, the less he finds.
Should we stop in our pursuit? Should we halt our progress to shorten the despair? No. Though knowledge is lost when knowledge is gained, no knowledge forfeits the progress of man. Man progresses to aid and insure the wellness of ages to come. The feeling of fulfillment is an exciting pleasure only explorers of the mind can understand. Whether you are an explorer or not depends on your pursuit of knowledge.
Just be prepared to know nothing.
