Bernardino Telesio (1509–1588) “The ethics exposed in the 9th book of De rerum natura is strictly naturalist. The only objective which Telesio ascribes to the spirit is self-preservation and self-improvement …”. The importance of knowledge comes from the self-preservation and- improvement.
- Self-preservation and self-improvement characterize spirit.
- Knowledge is a component of spirit.
- Natural philosophy and medicine are theoretical knowledge.
- Knowledge to control is subkind of knowledge and terminates emotion and desire.
- Emotion and desire can be provoked and suppressed.
