Louie found the raft offered an unlikely intellectual refuge. He had never recognized how noisy the civilized world was. Here, drifting in almost total silence, with no scents other than the singed odor of the raft, no flavors on his tongue, nothing moving but the slow porcession of shark fins, every vista empty save water and sky, his time unvaried and unbroken, his mind was freed of an encumbrance that civilization had imposed on it. In his head, he could roam anywhere, and he found that his mind was quick and clear, his imagination unfettered and supple. He could stay with a thought for hours, turning it about.
