"Value is this lacking-being of which freedom makes itself a lack; and it is because the latter makes itself a lack that value appears. It is desire which creates the desirable, and the project which sets up the end. It is human existence which makes values spring up in the world on the basis of which it will be able to judge the enterprise in which it will be engaged. But first it locates itself beyond any pessimism, as beyond any optimism, for the fact of its original springing forth is a pure contingency. Before existence there is no more reason to exist than not to exist. The lack of existence can not be evaluated since it is the fact on the basis of which all evaluation is defined. It can not be compared to anything for there is nothing outside of it to serve as a term of comparison."
