If you were stranded in an ocean, the only way to survive would be to float. You would struggle to float—and if you lost that struggle you would sink to your death. And if you refused to float, for fear of sinking, you would surely sink and die. You must float to survive. This logic applies also to the analysis of human knowledge—for we float unsupported in an ocean of ignorance. We seek foundations for our knowledge, solid ground, to escape the terror of floating. But in regard to knowledge, there are no foundations. The only solid ground is the ocean floor. To live is to float. To refuse to float is to die.
