Answer: intellect (or understanding)
Step-by-step explanation:
According to Descartes, humans have an infinite or unlimited will (free will) but limited intellect (or understanding). Descartes believed that the human mind or soul possesses free will, is not subject to external influences or determinism, capable of making decisions independent of causal factors. However, Descartes also recognized that the human intellect, or mind, has limitations and is limited in its ability to comprehend the
complexities of the world. Descartes argued that our senses and perceptions can be misleading and that true knowledge can only be attained through clear and unambiguous ideas derived from rational thought and deductive reasoning. Descartes' philosophy of dualism, which separates the mind or soul from the body, posits that the will is unlimited while understanding is limited and fallible.
