How do you bristle when you here about Truth?
It is not Becuase you are so intelligent or philosophically apt.
It is because the notion of Truth informs the core of an offense which holds up your system of sense and ability.
A logic of ideas supported by a fundamental and basic offense is called, in one instance, ideology, and in another, religion.
Ponder, great souls and great minds, how intelligence, ethics, and indeed the whole world itself, is contained by a knowledge that is nothing less than a religious theology. Less a system in which individuals of various cultures persist, than a manner which is the universe itself arising to be known.
