Modern man - although a unity of body, mind, and soul - exhibits a changed consciousness: every expression of his life has today a different aspect, … - Piet Mondrian

Vertical and horizontal lines are the expression of two opposing forces; they exist everywhere and dominate everything; their reciprocal action constitutes 'life'. I recognized that the equilibrium of any particular aspect of nature rests on the equivalence of its opposites.

I believe that in our period it is definitely necessary that, as far as possible, the paint is applied in pure colours, set next to each other in a pointillist or diffuse manner. This is stated strongly, and yet it relates to the idea which is the basis of meaningful expression in form, as I see it. It seems to me that the clarity of ideas should be accompanied by a clarity of technique.

When I first saw the work of the Impressionists, Van Gogh, Van Dongen and the Fauves, I admired it. But I had to seek the true way alone.
