The love of simplicity, precision and clarity, is totally Western. Today's rational plastic form does not come from the Mediterranean or the Orient; … - Fernand Léger

It is a true, incorruptible purism.. .It is a religion that cannot be argued about. It has its saints, its disciples and its heretics. Modern life with its speed and tumult, dynamic and full of contrasts, beats furiously against this light, luminous, delicate structure, which emerges coldly from the chaos. Do not touch it, it is an accomplished fact. It had to be, it is there to stay. [quote, 1945]

Of the various plastic orientations developed over the past twenty-five years, abstract art is the most important, the most interesting.. .It is an extreme state which only a few creators and admirers are capable of achieving. The danger of this formula lies in the very elevation of its intention. Modelings, contrasts, objects have disappeared, leaving only very pure, very precise relations, and a few colors, a few lines; blank spaces, without depth. Add to this a respect for the vertical plane – thin, rigid, sharp. It is a true, incorruptible purism.

An example: if I compose a picture using as objects a scrap of bark, a scrap of butterfly wing and a purely imaginary form, you probably won't recognise the bark, or the butterfly wing, and you'll say: 'What does this stand for? It is an abstract picture. No it's a representational picture'.. .There is no such thing as 'abstract', or 'concrete' either. There is a good picture and a bad picture. There is the picture that moves you and the picture that leaves you cold.. .A picture has a value in itself, like a musical score, like a poem.
