The reckoning with idealism as a view of life is universal, but it also touches on something central in art-its life's substance. One must understand that it is impossible to distinguish between a picture's form and its substance. As the flower's structure is governed by the intentional tension (when it loses the sap the form is lost), so also with art the substance creates the tension. Form and substance are one and the same. Form is the life expression and substance the living painting.
