The work of the sculptors of my age & somewhat older – Brancusi – Arp – Lipschitz – Laurens – Giacometti – has gradually approached a freedom & moved into space, compared with the sculptors of earlier period – Rodin – Maillol [. And] & the young sculptors of today all have the tendency to work with space – to model rather than carve – but it is very necessary in my opinion to have been able to get the refinement & completeness of a single form before going on to space form with no body.
