The Importance of Sensation in the Natural World

In Telezio's view, sensation is really just the ability to respond to being affected. The mere fact that cold and heat flee one another shows that they are in a very crude way,. while stones and plants have yet more sophisticated forms of sensation. In humans, sensation occurs when the warm spirit that flows through the body is affected by things in the person's environment. This soul is no longer a substantial form, but warm air or spirit circulating through the body.
