Schopenhauer essentially suggested that the world as we know and experience it is exclusively a representation created by our mind through our senses and forms of cognition. Consequently, we cannot access the true nature of external objects outside our mental, phenomenological experience of them. Deviating from Kant, Schopenhauer would go on to argue that not only can we not know nor access the varying objects of the world as they really are outside of our conscious experience, but there is, in fact, no plurality of objects beyond our experience at all.
