Epistemology is described as the branch of philosophy that concerns itself with questions regarding human knowledge. One particular epistemological question relates to the Object - Subject distinction and asks whether the objective world is subjectively knowable at all. It has been proposed that the real (objective) world and our (subjective) perception of the real world are not the same. Descartes (1641) argued that all that we can know of the real world is tainted by our senses and abilities of understanding. Kant (1998 [1781]) distinguished between the unknowable Ding an sich (German: The thing in itself) and the knowable Erscheinung (German: Phenomenon). Postmodernism contends that the notion of reality is an illusion. Quine (1964) described physical objects as mere cultural posits, and cognitive psychology and neuroscience have presented evidence that sense experience, the 'bedrock of empirical knowledge', is actively edited by human perception. Such 'editing' renders sense experience subjective to the particular observer.
