Avicenna (Philosopher)

Avicenna, also known as Ibn Sina, was a Persian philosopher and polymath active in the 10th and 11th centuries. He made significant contributions to philosophy, medicine, and the sciences. His most notable work, "The Book of Healing," explores logic, natural sciences, and metaphysics. Avicenna is often considered a key figure in the development of Islamic philosophy, linking Greek thought with later European philosophy. He is also credited with early ideas about the nature of the soul and the concept of "existence" versus "essence." His influence shaped both Islamic and Western intellectual traditions for centuries.
