"I am the way and the truth" said Jesus. Also "speak truth to you neighbor and put away false hood".
This reverence for truth in Christianity also leads to its undoing in the information age of science and technology.
Nihilism is often associated with the German philosopher Friedrich Nietzsche, who provided a detailed diagnosis of nihilism as a widespread phenomenon of Western culture. Though the notion appears frequently throughout Nietzsche's work, he uses the term in a variety of ways, with different meanings and connotations. Karen Carr describes Nietzsche's characterization of nihilism "as a condition of tension, as a disproportion between what we want to value (or need) and how the world appears to operate." When we find out that the world does not possess the objective value or meaning that we want it to have or have long since believed it to have, we find ourselves in a crisis. Nietzsche asserts that with the decline of Christianity and the rise of physiological decadence,[clarification needed] nihilism is in fact characteristic of the modern age, though he implies that the rise of nihilism is still incomplete and that it has yet to be overcome. Though the problem of nihilism becomes especially explicit in Nietzsche's notebooks (published posthumously), it is mentioned repeatedly in his published works and is closely connected to many of the problems mentioned there.
Nietzsche characterized nihilism as emptying the world and especially human existence of meaning, purpose, comprehensible truth, or essential value. This observation stems in part from Nietzsche's perspectivism, or his notion that "knowledge" is always by someone of some thing: it is always bound by perspective, and it is never mere fact. Rather, there are interpretations through which we understand the world and give it meaning. Interpreting is something we can not go without; in fact, it is something we need. One way of interpreting the world is through morality, as one of the fundamental ways that people make sense of the world, especially in regard to their own thoughts and actions. Nietzsche distinguishes a morality that is strong or healthy, meaning that the person in question is aware that he constructs it himself, from weak morality, where the interpretation is projected on to something external. Regardless of its strength, morality presents us with meaning, whether this is created or 'implanted,' which helps us get through life.
Nietzsche discusses Christianity, one of the major topics in his work, at length in the context of the problem of nihilism in his notebooks, in a chapter entitled "European Nihilism". Here he states that the Christian moral doctrine provides people with intrinsic value, belief in God (which justifies the evil in the world) and a basis for objective knowledge. In this sense, in constructing a world where objective knowledge is possible, Christianity is an antidote against a primal form of nihilism, against the despair of meaninglessness. However, it is exactly the element of truthfulness in Christian doctrine that is its undoing: in its drive towards truth, Christianity eventually finds itself to be a construct, which leads to its own dissolution. It is therefore that Nietzsche states that we have outgrown Christianity "not because we lived too far from it, rather because we lived too close". As such, the self-dissolution of Christianity constitutes yet another form of nihilism. Because Christianity was an interpretation that posited itself as the interpretation, Nietzsche states that this dissolution leads beyond skepticism to a distrust of all meaning.
