Final answer:
Maimonides, along with Socrates and Indian philosophers, argues that the primary source of all evil is ignorance, as people always choose what seems good to them, and only do harm out of a mistaken belief that it will bring them good.
Step-by-step explanation:
According to Maimonides, the primary source of all evil is ignorance. He concurs with other philosophers like Socrates and the Indian philosophers that evil actions stem from a lack of knowledge or understanding. People always desire what they believe to be good, and they only choose what they perceive as harmful because they mistakenly believe it will yield some benefit to them. This incorrect belief is due to ignorance. If individuals were fully aware of the consequences of their actions, they would not choose to do evil. The connection between ignorance and suffering is also notable in Indian philosophy, where suffering is linked to attachment, which is again a product of ignorance.
