L ocke's Reply to the Skeptic

Given his representationalism how can L ocke claim we have sensitive knowledge of the external world? We can see the skeptic as asking two different questions: how we can know the existence of external things, or more specifically how we can know inferentially of the existence of external things. L ocke's account of sensitive knowledge, a form of non‐inferential knowledge, answers the first question. All we can achieve by inference is highly probable judgment. Because L ocke's theory of knowledge includes both first order psychological and second order normative conditions, sensitive knowledge can be non‐inferential and less certain than intuitive and demonstrative knowledge.
