Truth is that which is. That which is happening now and that which has happened. It is that which exists, inkluding all seen and unseen laws of nature.
The existence of truth is affirmed through the contradiction that arises when attempting to deny it. For instance, if one asserts “there is no truth,” this statement itself is presented as a truth claim. For this claim to be valid, it paradoxically requires its own negation to be true, implying that there is, in fact, one objective truth.
