Passage from "The immortality of the soul" by David Hume
Where any two items x and y are so closely connected that all alterations we have ever seen in x are accompanied by corresponding alterations in y, we ought to conclude—by all the rules of analogy—that when x undergoes still greater alterations, so that it is totally dissolved, a total dissolution of y will follow.
How is that scientific? Does a strong correlation between two things imply that both things are always connected?
