Descartes' goal, as stated at the beginning of the meditation, is to suspend judgment about any belief that is even slightly doubtful. The skeptical scenarios show that all of the beliefs he considers in the first meditation—including, at the very least, all his beliefs about the physical world, are doubtful. So he decides to suspend judgment. He will henceforth give up all of his beliefs about the physical world. He also decides to continually remind himself to avoid habitually falling into accepting beliefs without support, a habit to which he is susceptible.
