All the pictures [in the exhibition, 1910] include a plus-factor, which robs the public [in Munich] of her pleasure but which is in every case the principal merit of the work; the completely spiritualized, de-materialized awardness of perception, which our fathers, the artists of the nineteenth century, never even tried to achieve in their 'pictures'. This bold undertaking, to take the 'matiere', which Impressionism sank its teeth into, and spiritualize it, is a necessary reaction, which began with Gauguin in Pont-Aven, and has already fostered innumerable experiments... The way the Munich public condemns the exhibition is almost amusing.
