“How significant is the enormous heightening, under mescalin, of the perception of color! … Man's highly developed color sense is a biological luxury—inestimably precious to him as an intellectual and spiritual being, but unnecessary to his survival as an animal. … Mescalin raises all colors to a higher power and makes the percipient aware of innumerable fine shades of difference, to which, at ordinary times, he is completely blind. It would seem that, for Mind at Large, the so-called secondary characters of things are primary.”

version in original Dutch (citaat van Johannes Bosboom, in Nederlands): De romantische beweging onder aanvoering van den genialen nl:Wijnand Nuijen trok ook mij aan tot volgen. En al verviel men langs dien weg in gekleurdheid en opgesmuktheid, vaak ontaardend in chic; er ontsproot daaruit later een meer verstandig zoeken naar verlevendiging van coloriet, verhooging van effect, vermeerdering van reliëf.
