..the elements of form have a particular aspect; every fragment, every plane, every line has its proper character. - Piet Mondrian

A form must be of its own time if it is to be recognized: one cannot relate to what one is not or does not have – Thus all that is of the past is to be rejected.

Only through intuition does a work rise above more or less subjective expression. Different periods produce different feelings and conceptions, and in each period men differ. Consequently different art expressions even in a single period are not only logical but a tribute to the general development of art. Intuition always finds the way of progress, which is continuous growth toward a clearer establishment of the content of art: the unification of man with the universe.

[the double line in his paintings] is still one line, as in the case of your grooves [= the wide sunken lines in the relief's, the artist Gorin made then].. .In my last things the double line widens to form a plane, and yet it remains a line. Be that as it may, I believe that this question is one of those which lie beyond the realm of theory, and which are of such subtlety that they are rooted in the mystery of 'art'. But all that is not yet clear in my mind.
