As for primary truths of fact, these are inner experiences which are immediate with the immediacy of feeling. This is where the first truth of the Cartesians and St Augustine belongs: I think, therefore I am. That is, I am a thing which thinks. But . . . not only is it immediately evident to me that I think, but it is just as evident that I think various thoughts: at one time I think about A and at another about B and so on.
