Nietzsche also argues that living without falseness is impossible. To function at all in life, we have to use logic, simple maths and geometry etc. regardless of them being true or not. The "falseness" of such judgements is "no objection to them." "Untruth is a condition of life.".
The distinctions between the True and the false, or the apparent and True in terms of oppositions is to Nietzsche one of the main prejudices of philosophers. They would not be able to accept that truth may have its origin in error, or that something like selflessness may have stemmed from selfishness. So they invent a pure, godly, origin for the virtues the value. Plato is accused of being the first to make this move. Nietzsche accuses language of making us believe in simple oppositions, when in reality there is only "degrees and many subtleties of variation". For Nietzsche, language does not neutrally reflect the world, nor does thought in some way transcend language. Rather, language fixes and determines the way in which we perceive.
Due to Nietzsche's firm belief that humans have a natural will to power or to live, he believes that truth and falsity of a belief is less important compared to its life-advancing quality. Nietzsche argues if something has the ability to improve or extend life, what difference does it make if it is true or not? It improves our lives regardless.
With such arguments against Truth, Nietzsche feels that it is necessary that we re-evaluate the definition we have for Truth. Nietzsche proposes that we change the model of Truth, to Truth being equal to interpretation. Again this relates to his idea of Perspectivism, where as there is no being that affirms absolution, we are only left with our views and perspectives. But it also leads to Nietzsche's view of immediate certainties. Immediate certainties are mainly associated with Descartes" foundationalist theories, most importantly the famous Cogito argument.
