It is not always best, all things considered, to believe the truth. That does not mean truth is not intrinsically valuable. Rather, it means that truth's intrinsic value is finite.

Is truth a value?
In classical logic, with its intended semantics, the truth values are true (denoted by 1 or the verum ⊤), and untrue or false (denoted by 0 or the falsum ⊥); that is, classical logic is a two-valued logic. This set of two values is also called the Boolean domain.
