I started above all by producing still-lives because in nature there is a tactile space, I would say almost manual. - Georges Braque

What greatly attracted me – and it was the main line of advance of Cubism – was how to give material expression to this new space of which I had an inkling. So I began to paint chiefly still life's, because in nature there is a tactile, I would almost say a manual space. I wrote about this moreover 'When a still-life is no longer within reach, it ceases to be a still-life...'. For me that expressed the desire I have always had to touch a thing, not just to look at it. It was that space that attracted me strongly, for that was the earliest Cubist painting – the quest for space.

The only valid thing in art is that which cannot be explained. To explain away the mystery of a great painting – if such a feat were possible – would be irreparable harm.. .If there is no mystery then there is no 'poetry', the quality I value above all else in art. What do I mean by 'poetry'? It is to a painting what life is to man.. .For me it is a matter of harmony, of rapports, of rhythm and – most important for my own work – of 'metamorphosis'

Take the birds which you'll have noticed in so many of my recent paintings. I never thought them up, they just materialized of their own accord, they were born on the canvas; that is why it is absurd to read any sort of symbolic significance into them.
