Logic is the attempt on our part to understand the actual world according to a scheme of Being devised by ourselves; or, more exactly, it is our attempt at making the actual world more calculable and more susceptible to formulation, for our own purposes.... 33 "Truth" is the will to be master over the manifold sensations that reach consciousness; it is the will to _classify_ phenomena according to definite categories. In this way we start out with a belief in the "true nature" of things (we regard phenomena as real). The character of the world in the process of Becoming _is not susceptible of formulation;_ it is "false" and "contradicts itself." _Knowledge_ and the process of evolution exclude each other. _Consequently,_ knowledge must be something else; it must be preceded by a will to make things knowable, a kind of Becoming in itself must create the _impression_ of _Being._ 33-34. _The chief error of psychologists:_ they regard the indistinct idea as of a lower _kind_ than the _distinct;_ but that which keeps at a distance from our consciousness and which is therefore _obscure, may_ on that very account be quite clear in itself. _The fact that a thing becomes obscure is a question of the perspective of consciousness._ 42 The criterion of truth lies in the enhancement of the feeling of power. 49 Logic was intended to be a method of facilitating thought: _a means of expression,_--not truth.... Later on it got to _act_ like truth.... 50 In a world which was essentially false, truthfulness would be an _anti-natural tendency:_ its only purpose would be to provide a means of attaining to a _higher degree of falsity._ 51 We have absolutely no experience concerning _cause;_ viewed psychologically we derive the whole concept from the subjective conviction, that _we_ ourselves are causes. 55 "Truth" is not something which is present and which has to be found and discovered; it is something _which has to be created_ and which _gives_ its name _to a process,_ or, better still, to the Will to overpower, which in itself has no purpose.... 60 The absolute is even an absurd concept: an "absolute mode of existence" is nonsense, the concept "being," "thing," is always _relative_ to us. The trouble is that, owing to the old antithesis "apparent" and "real," the correlative valuations "little value" and "absolute value" have been spread abroad. 83 Man seeks "the truth": a world that does not contradict itself, that does not deceive, that does not change, a _real_ world--a world in which there is no suffering: contradiction, deception, variability--the causes of suffering. He does not doubt that there is such a thing as a world as it ought to be; he would fain find a road to it.... Obviously, the will to truth is _merely_ the longing for a _stable world._ The senses deceive; reason corrects the errors: _therefore,_ it was concluded, reason is the road to a static state; the most _spiritual_ ideas must be nearest to the "real world." 88
