I will be concerned in these pages with the views that Gilbert Harman puts forward in his immensely stimulating paper Self-Reflexive Thoughts.<sup>1</sup> Harman maintains that self referential thoughts are possible, and also that they are useful. I applaud both of these claims. An example of a self referential thought is the thought that every thought, including this present one, has a logical structure. I feel sure that this thought exists, for I have entertained it on a number of occasions. Moreover, I feel that it is extremely useful. Without deploying it, how could we tell the whole truth about the nature of thoughts?
