"And for me Michelangelo's greatest work is one that was in his studio partly finished, partly unfinished when he died 'The Rondanini Pietà'. I don't know of any other single work of art by anyone that is more poignant, more moving. It isn't the most powerful of Michelangelo's works – it's a mixture, in fact, of two styles.. ..the changing became so drastic that I think he knocked the head off the sculpture.. .So the figure must originally have been a good deal taller. And if we see also the proportion of the length of the body of Christ compared with the length of the legs, there's no doubt that the whole top of the original sculpture has been cut away. Now this to me is a great question. Why should I and other sculptors I know, my contemporaries – I think that Giacometti feels this, I know Marino Marini feels it – find this work one of the most moving and greatest works we know of when it's a work which has such disunity in it?.. .But that's so moving, so touching: the position of the heads, the whole tenderness of the top part of the sculpture, is in my opinion more what it is by being in contrast with the rather finished, tough, leathery, typical Michelangelo legs. The top part is Gothic and the lower part is sort of Renaissance."

“The violent quarrel between the abstractionists and the surrealists seems to me quite unnecessary. All good art has contained both abstract and surrealist elements, just as it has contained both classical and romantic elements – order and surprise, intellect and imagination, conscious and unconscious. Both sides of the artist’s personality must play their part. And I think the first inception of a painting or a sculpture may begin from either end.”

“This is what the sculptor must do. He must strive continually to think of, and use, form in its full spatial completeness. He gets the solid shape, as it were, inside his head - he thinks of it, whatsoever its size, as if he were holding it completely enclosed in the hollow of his hand. He mentally visualizes a complete form..”

“Mexican sculpture, as soon as I found it, seemed to me true and right, perhaps because I at once hit on similarities in it with some eleventh-century carvings I had seen as a boy on Yorkshire churches. Its 'stoniness', by which I mean its truth to material, its tremendous power without loss of sensitiveness, its astonishing variety and fertility of form-invention and its approach to a full three-dimensional conception of form, makes it unsurpassed in my opinion by any other period of stone sculpture.”

“Since the Gothic, European sculpture had become overgrown with moss, weeds – all sorts of surface excrescences which completely concealed shape. It has been Brancusi's special mission to get rid of this overgrowth, and make us once more shape-conscious. To do this he has had to concentrate on very simple direct shapes, to keep his sculpture, as it were, one-cylindered, to refine and polish a single shape to a degree almost too precious.. ..it may now be no longer necessary to close down and restrict sculpture to the single form unit. We can now begin to open out. To relate and combine together several forms of varied sizes, sections, and directions into one organic whole.”

“One room after another in the British museum took my enthusiasm. The Royal College of Art meant nothing in comparison. Every Wednesday, Saturday, and Sunday I would go to the British Museum. But not till after three months did things begin to settle into any pattern of reality for me. Till then everything was wonderful – a new world at every turn. That is the value of the British Museum: you have everything behind you; you are free to try to find out your own way and, after a while, to find what appeals to you most. And after the first excitement it was the art of ancient Mexico that spoke to me most – except perhaps Romanesque, or early Norman. And I admit clearly and frankly that early Mexican art formed my views of carving as much as everything I could do.”
