This chapter considers, relying in part upon comparative semantic evidence from English and Romanian, two contrasting dimensions of the sense in which the authors' thoughts, including the contents of imagination and memory, and objects of fear, may be distinctively first-personal, or de se, to use the terminology introduced in Lewis, and exhibit the phenomenon of immunity to error through misidentification (IEM) in the sense of Shoemaker. There are de se triggers in Romanian, but they do not behave as uniformly as unpronounced (PRO) subject does in English. This difference suggests that context showing IEM or being intrinsically de se is to be explained by appealing to different linguistic considerations. The linguistic parameters of the de se are variable, and that elements of thought as reported in language may be de se, and so subject to IEM, where they are taken from other points of view than that of the experiencer.
