The principle of objectivity can, I think, be applied to every human experience, but is often quite out of place. For instance: what is a fugue by Bach? Is it the invariant cross-section, or the common content of all printed or written copies, gramophone records, sound waves at performances, etc., of this piece of music?
Unanimity of opinion may be fitting for a church, for the frightened or greedy victims of some (ancient, or modern) myth, or for the weak and willing followers of some tyrant. Variety of opinion is necessary for objective knowledge. And a method that encourages variety is also the only method that is comparable with a humanitarian outlook.
The function [of objective thinking] is to reduce all phenomena which bear witness to the union of subject and world, putting in their place the clear idea of the object as in itself and of the subject as pure consciousness. It therefore severs the links which unite the thing and the embodied subject.
