In regard to the relatively trivial examples of aesthetic objects treated so far, our pleasure rested in each case on an intuitive presentation of something external (on the presentation of `physical phenomena' in Brentano's sense). We have now, however, reached a point where we must turn inward and consider the feelings of higher order aesthetic pleasure which are provoked by our presentations of mental, and particular emotional, phenomena themselves. That is we must turn to those aesthetic experiences which are provoked by what Brentano, Meinong and Witasek called the `inner perception' of psychic phenomena and by the peculiar modifications.
