Abstract

“Hume’s Problem” is one of those great theoretical problems in modern ethics and axiology studies, the essence of which is the logical relationship between value and fact. The legal ground and rational route from “fact” to “value” lie in the revealing of the relationship of negative unity between value and fact. The basis and medium of this relationship are the “factual contradiction” and “actual dilemma” faced by us. The means of negative unity between value and fact in study is one kind of “factual epistemic means”, which is one general study means both different and relevant to “value expression means”.
