Consider This Quote: Rodin on The Thinker

Nature gives me my model, life and thought;
the nostrils breathe, the heart beats, the lungs inhale,
the being thinks, and he feels and has pains and joys,
ambitions, passions and emotions. These I must express.
What makes my Thinker think is that he thinks not only with his brain,
with his knitted brow, his distended nostrils and compressed lips,
but with every muscle of his arms, back and legs,
with his clenched fist and his gripping toes.

— Auguste Rodin, French sculptor, speaking of his most famous art work Le Penseur (also known as The Thinker)
