The truth is undeniably a basic condition for any form of understanding or communication.
Every utterance assumes the existence of some truth and is judged according to it.
It is thanks to this fact that, for example, sarcasm is possible. The realization that truth is present in all spoken words lies at the heart of the philosophical tradition that concentrates on truthful judgment. All attempts at defining the truth emerge from this conception. The most famous of those attempts states that truth is an agreement between the understanding and the object. The weakness of this theory lies in the fact that it cannot say what this agreement is based on.
