“ The demonstration of the ‘thorough-going subjectivity of all the elements of our cognition,’—sensations, pure intuitions, and pure notions of the understanding,—is in no respect decisive against the assumption of the existence of ‘a world of Things outside ourselves.’ For it is clear that this ‘subjectivity of cognition’ must in any case be true, whether ‘Things’ do, or do not exist. For even if ‘Things’ exist, still our cognition of them cannot consist in their actually finding an entrance into us, but only in their exerting an action upon us. ”
