'dialogue on the new plastic'

A(A singer):But I still don't understand why you favor the straight line and have come entirely to exclude the curved.
B(A painter): The search for the expression of vastness led to the search for the greatest tension:
the straight line; because all curvature resolves into the straight, no place remains for the curved.
