"There are moments in our lives, there are moments in a day, when we seem to see beyond the usual – become clairvoyant. We reach then into reality. Such are the moments of our greatest happiness. Such are the moments of our greatest wisdom. 

At such times, there is a song going on within us, a song to which we listen. It fills us with surprise. We marvel at it. We would continue to hear it. But few are capable of holding themselves in the state of listening to their own song. Intellectuality steps in and as the song within us is of the utmost sensitiveness, it retires in the presence of the cold material intellect . . . yet we live in the memory of these songs . . . They are the pinnacles of our experience and it is the desire to express these intimate sensations, this song from within, which motivates the masters of all art."

Robert Henri, The Art Spirit
