"And now about architects in general – I have to say it, Does , when 'De Stijl' was founded I left it up to you, but I never did agree with you when you ranked the architects alongside us, alongside our 'N.B.'

“Culture produces relative consciousness of the changeable expression of reality. When this consciousness is attained, a revolt takes place: the beginning of the deliverance from that expression of reality. Destruction of its limitation follows. The culture of the intuitive faculties has conquered. A clearer perception of constant reality is possible. A new realism appears.”

“..the elements of form have a particular aspect; every fragment, every plane, every line has its proper character.”
