Although strictly speaking philosophy is not specialized in studying problems of facts
(typical philosophical problems are conceptual, normative, and/or textual problems
rather than factual problems), it not only should take problems of facts into considerations
when it is studying conceptual, normative, and textual problems, but also
should take the concept of “fact” as one of its most important subject matters.
“Fact” is not a purely technical term in the field of philosophy; it is also a concept
frequently used in everyday life. One way of making philosophical sense of this
concept is to understand the relation between the concept “fact” and other relevant
concepts, such as “fiction,” “value,” “theory,” “statement,” “things,” “events,” “the
given,” “existents,” “truth,” “evidence,” and so on.
