Hume seeks to explain our understanding of the world rather than try to justify our beliefs or prove anything. Here, he does not address the existence of necessary connections between events but states merely that we cannot know what those connections are. Ultimately, Hume argues for a mitigated skepticism. We have no good reason to believe much of what we believe about the world, but human nature helps us function in all the ways that reason cannot. However, we must limit ourselves by accepting that matters of fact are our sole source of true information. If past experience cannot teach us about the future, it becomes difficult to function on a practical level. The elimination of causation would make it impossible for us to function, if it meant that we began to act as if causation didn’t exist. Whether or not we can know of a necessary connection between two events is not worth arguing about. Similarly, Hume does not think we should spend time and energy on questions such as whether God exists, what the soul is, or whether the soul is immortal. He claims that because the mind is not meant to help us discover and define truths, we will never be able to come to any definite and rational conclusions about abstract matters.
