Pebbles and rocks show nature's way of working stone. Smooth, sea-worn pebbles show the wearing away, rubbed treatment of stone and principles of asymmetry.
Rocks show the hacked, hewn treatment of stone, and have a jagged nervous block rhythm.
Bones have marvelous structural strength and hard tenseness of form, subtle transition of one shape into the next and great variety in section. They give the ideal for wood sculpture, upward twisting movement. My aim in work is to combine, as intensely as possible, the abstract principles of sculpture along with the realization of my idea. Abstract qualities of design are essential to the value of a work, but to me of equal importance is the psychological, human element. On the principle of the arch, it can remain just as strong.
