Instinct reveals itself as self-concentrating, self-edifying it is limitation. Intuition produces self-denial, self-destruction； it is expansion. Cul… - Piet Mondrian

It may be noted that in Neo-Plastic art the crucial thing is the right angel, that is, the right-angle lines. And not whether the position of the lines is vertical or horizontal.. .So it is possible to make very beautiful things while placing the lines in a diagonal position.

In his later works Doesburg tried to destroy static expression by diagonal position of his lines. But in this way the feeling of physic equilibrium which is necessary to enjoy a work of art is lost.

For when I construct lines and colour combinations on a flat surface, it is with the aim of portraying 'universally beauty' as consciously as possible. Nature (or that which I see) inspires me, provides me – as it does every painter – with the emotion by which I am moved to create something, but I want to approach the truth as closely as possible, abstracting everything until I come to the foundation – still only an outward foundation! – of things. It is for me a clear truth that one does not want to say something 'specific', it is then that one says what is most specific: the truth (which is of great universality).
