In this paper I discuss possibility of finding sense to difference, stated by Hannah Arendt, between facts and factual truths. One consequence of difficulty in distinguishing these two terms is that it turns equally difficult to see if it is factual truth, instead of facts, that can be substituted by power of lies. From this derives an additional problem related to first, i.e.: what does Arendt understand under what she calls the stubbornness of facts. To show these difficulties I use an example from Colombian history and trace path which leads from systematically denying a series of facts, talking about them as if they were unimportant and finally allow them to be entirely replaced by pieces of fantastic literature until they lose their stubbornness.
