The sculptor carves because he must. He needs the concrete form of stone and wood for the expression of his idea and experience, and when the idea forms the material is found at once. .... I have always preferred direct carving to modelling because I like the resistance of the hard material and feel happier working that way. Carving is more adapted to the expression of the accumulative idea of experience and clay to the visual attitude. An idea for carving must be clearly formed before starting and sustained during the long process of working; also, there are all the beauties of several hundreds of different stones and woods, and the idea must be in harmony with the qualities of each one carved; that harmony comes with the discovery of the most direct way of carving each material according to its nature.
