I demonstrate that post-truth and fake news, as well as less frequently discussed in philosophy dis-information, mis-information, certain types of propaganda and other related pseudo-news, have the character of pragmatic truth in William James’s understanding. I call these phenomena, which form a family, instrumental messages. It is not correct to explain them as lies, or equivalently as falsehoods in the common sense, i.e. as negations of classical truth, i.e. truth that objectively represents reality. Although, which may seem paradoxical, instrumental messages are usually such falsehoods. These messages are means of action, or more specifically, means of realizing the interests of their beneficiaries by means of cognitive camouflage. The camouflage is correspondence truth. The current eruption of post-truths, fake news and other instrumental messages is a result of the spread of a pragmatic system of values. This eruption manifests a profound civilizational change, consisting in the instrumentalization of the social world and in this also in the adjustment of values to particular interests, non-universal, variable, not subordinated to „eternal” guiding ideas.
