Hume's Conclusion

[...]there is a direct and total opposition betwixt our reason and our senses; or more properly speaking, betwixt those conclusions we form from cause and effect, and those that persuade us of the continud and independent existence of body. [...]he must explain how it can be that the philosophers are so satisfied with their lousy explanations.Ordinary people take their perceptions to be objects. Usually called the argument from the variability of perception, the argument maintains that in different states of awareness or attention, in different positions, or under different conditions, we have varying, sometimes incompatible, impressions, while the external object, to all appearances, remains the same (T 226). Since all these impressions cant resemble the object, we conclude that many of our impressions have no external model or archetype. [...]knowledge reduces to probability, and becomes at last of the same nature with that evidence, which we employ in common life (T 181).Hume then moves to consider probable reasoning, to see on what foundation it stands.
