“As far as immediate material production is concerned, the decision whether an object is to be produced or not, i.e., the decision on the value of the object, will depend essentially on the labor time required for its production. For it depends on that time whether society has time to develop in a human way. And even as far as intellectual production is concerned, must I not, if I proceed reasonably in other respects, consider the time necessary for the production of an intellectual work when I determine its scope, its character and its plan? Otherwise, I risk at least that the object that is in my idea will never become an object in reality, and can therefore acquire only the value of an imaginary object, i.e., an imaginary value.”
