What did aquinas maintain concerning the human soul?

Aquinas maintained that the human soul is the form of the body, meaning it gives life and purpose to the physical being. He believed that the soul is immaterial and immortal, capable of existing independently of the body after death. Additionally, he posited that the soul has intellectual and rational capacities, distinguishing humans from other living beings. Ultimately, for Aquinas, the soul's ultimate goal is to achieve union with God.
