One potential implication from the quote could be that all deception roots from some aspect of the real. Lies are not constructed out of a vacuum. There is some condition in realistic consciousness that causes the person to construct the lie. One lies because their reality necessitates it or because the lie is more preferable to the realistic condition in which one is immersed. This would mean that there is some level of "truth" within a lie. While it is human nature to dismiss lies and deception and not find anything relevant in them, the quote compels us to examine the conditions in reality that might be reflected in lies and acts of deception.
