 speaking of perception here [that is, of perception as applied to mental states] is just as correct as speaking of perception in the case of three-dimensional objects. […] The sympathizer [der Sympathisierende] perceives that the other expresses certain mental experiences and, therefore, also perceives these experiences, but he does not live through them himself, which just means that he does not have an adequate inner perception [of these experiences]. (1908: 46f)
