From the moment a person is born, is there ever a point where they actually tell the truth?
Socrates, upon realizing the axiomatic nature of knowledge, was famously credited as saying "The only true wisdom is in knowing you know nothing". And so he would probably say no, but then paradoxically he actually tells the truth.
Everyone else would say yes, because they don't understand how they are lying. And so by believing they are telling the truth, they also, paradoxically, actually tell a lie.
The truth is a lie and the lies are the truth.
Long live insanity.
