 Thus the importance of Descartes’ First Meditation remark that “no danger or error will result” from the program of methodical doubt, “because the task now in hand does not involve action” (AT 7:22, CSM 2:15). Methodical doubt should not be applied to practical matters. Prudence dictates that when making practical decisions I should assume I’m awake, even if I don’t perfectly know that I’m awake. Judgment errors made while mistakenly assuming I’m awake couldn’t have actual practical consequences, unlike those made while mistakenly assuming I’m dreaming.
