If you think about it, a lie is in no respect a positive affirmation, when you know you are lying. You are merely contributing, if we want to use that word, an alternative version of the truth, one which you know to be inaccurate, but also know to be different from the currently accepted, or most obvious, one.
A lie, in other words, is a subversion of the truth. It is something which serves to obscure the truth. A lie, in Gramscian terms, might be termed a “counter-hegemonic narrative”, if we understand the dominant “hegemonic narrative” to be everything which a given society has always understood to be true.
And perhaps the most structurally important lie being told nowadays is that there is no truth. Of course there is truth. Jim, for example, might reliably be shown to have shot Sally last Tuesday in their apartment after a fight heard by numerous neighbors. It is always possible to be wrong about the truth, but that something happened is epistemologically a certainty as long as we grant this world exists, which all of these nearly universally atheistic materialists do.
And one can assert that the Notre Dame Cathedral is beautiful and the Centre Georges Pompidou is ugly as well. By and large, the people who will oppose you are those who oppose everything which was. And they do this by lying. They do not lack aesthetic taste, but, rather like the Underground Man, find themselves compelled to embrace everything ugly.
Certain truths are found in silence. Certain truths emerge from deep waters after long contemplation. These truths become impossible when people will not stop talking, will not stop lying, will not stop pushing. This is our current situation.
I am not entirely sure I am thinking clearly here, but perhaps there is something of use to someone. I have to run.
