Knowledge is limited to human perceptions and experiences from "summary" of A Treatise of Human Nature by David Hume
Human knowledge is, without a doubt, confined within the limits of our perceptions and experiences. It is through our senses that we acquire information about the world around us. Our perceptions of objects and events are the foundation upon which our understanding of reality is built. We can only know things that we have directly experienced or observed through our senses. When we see an object, we form a mental image of it based on the information provided by our senses. This mental image is the only knowledge we can have of the object. We cannot know anything about the object that is not derived from our sensory experience. Our knowledge is limited to what we can perceive and experience firsthand. Even when we reason about abstract concepts or engage in philosophical speculation, our knowledge is ultimately rooted in our perceptions and experiences. We may think about things beyond the reach of our senses, but our thoughts are still shaped by our sensory experiences. Our understanding of the world is constrained by the limitations of our senses. It is important to recognize the boundaries of human knowledge and to be humble in the face of our limitations. We cannot claim to have knowledge of things that lie beyond the scope of our perceptions and experiences. Our understanding is necessarily limited to what we can observe and sense.- Human knowledge is circumscribed by the boundaries of our perceptions and experiences. We can only know things that we have directly perceived or experienced through our senses. Our understanding of the world is constrained by the limitations of our sensory faculties. It is essential to acknowledge these constraints and to be mindful of the fact that our knowledge is always contingent upon our sensory experiences.
