It doesn't seem to me that any kind of long-term social enterprise could be carried out without some sort of "fixed principles" simply as a matter of maintaining sufficient coherence to know that what had been done before was connected to what was done after; if God were not in the grammar (and the vocabulary as well) we would have to have invented her if only in order to recognize ourselves. The insincerity of hiding her will multiply our labors.
The prohibition against fixed principles looks mighty like a fixed principle, in any case. _Panta_rhei_ -- compared to what?

This looks like a moral judgement, although it might be hidden under a thin veneer of utilitarianism. If there is no moral order, why not betray Marxism?
