"Not the completeness of the motif, the theme, the form: but the completeness of the painting is what makes the picture! And: it is the space created by the nature and quality of color and form, a flowing, halting, fleeting, limited, clear, blurred space, that becomes a picture. Space, then, and with that we would (for me) be back to Picasso and Beckmann." - Herrfurth in a diary entry from February 26, 1965
