A Matter of Fact
, in the Humean
sense, is the type of knowledge that can be characterized as arising out of one's interaction with and experience in the external world (as compared to a Relation of Ideas
). In a Kantian
framework, it is equivalent to the synthetic a posteriori
-The sun will come out tomorrow. (Not reason but habitual)
-There are people outside the room. (One cannot know what is outside one's own experience)
How We Know:
-It is impossible to "know."
-Depend upon The Principles of Induction and The Uniformity of Nature.
-Denying these do not lead to a contradiction.
