The mature person becomes able to differentiate feelings into as many nuances, strong and passionate experiences, or delicate and sensitive ones, as in the different passages of music in a symphony. Unfortunately, many of us have feelings limited like notes in a bugle call.
Rollo May... what the artist or creative scientist feels is not anxiety or fear; it is joy. I use the word in contrast to happiness or pleasure. The artist, at the moment of creating, does not experience gratification or satisfaction... Rather, it is joy, joy defined as the emotion that goes with heightened consciousness, the mood that accompanies the experience of actualizing one's own potentialities.
