OK, I admit that the position taken by Hegel in the Preface to The Philosophy of Right (see last post) is probably logically indefensible. In fact, when I first read it I thought it might be an example of that wonderful old-school genre of the Disingenuous Introduction to a big book of philosophy, an introduction intended to confuse the censors, appease the powerful, and partially conceal the radical implications of the philosopher's critique.
I don't think it is that, actually; rather I think it represents a position which Hegel believes is true but which he can't prove. Specifically, Hegel's argument is that moral and political philosophy should not be based on sentiment but rather on the existing social facts, yet his reasons for taking this view seem openly sentimental--he justifies this point of view based on his anger at the social effects of what he considers to be bad philosophy (which is, precisely, philosophy based on appeals to sentiment and/or appeals to possibility rather than fact). Basically, he is angry that such positions are discrediting philosophy. And yet, an appeal to the social status of philosophy is not a strong grounding for his position, since the high or low social status of philosophy has no intrinsic relation to whether philosophy is valid, or even to whether it should be done. It is easy to imagine scenarios in which valid philosophy would be rejected by state power (and of course, history is full of such scenarios, though Hegel could have argued the point by claiming that all of the historical examples of a philosophical position being sanctioned by a state are examples of invalid philosophy that the state was correct in sanctioning. I suspect he might have thought that, considering his comments about Plato in the Preface.)
I think a moral philosophy that is not based on sentiment is probably impossible, though it's exciting for Hegel to try to argue the possibility. Part of it is the tendency for German idealistic philosophers to write as if they hadn't read Hume--the weird "pre-Hume" character of German philosophy is one of the strangest things about it. (This means, basically, that they write about reason as if there were no such idea as "instrumental reason"--as if reason were always an end rather than merely another means--whereas Hume pointed out that reason was totally manipulable by the manipulation of premises--but the Germans just kept going on as if reason were an unerring road to truth rather than just a convenient multi-purpose tool.) In other words, German philosophy is based on a much more restricted definition of reason, in which the infinite possible manifestations of "instrumental reason" are, in the light of true reason, discoverable as distortions. This would imply that there's only one set of genuine premises, and, in this Preface, Hegel argues that those genuine premises are the existing social facts.
If we accept the polymorphous utility of reason (a main premise of the English philosophical tradition) than we are stuck basing moral reasoning on sentiment. Thus, morality becomes an opinion, of no more intrinsic weight than any other opinion. This is exactly what Hegel's Preface wants to save philosophy from. But his attempt to radically restrict the available premises is (IMHO) logically flawed.
Philosophy of government, law, or economics has to depart from existing social facts in order to theorize about the general cases (fields of possibility) of which the specific case (existing social facts) is only one manifestation. If philosophy doesn't do this, then it cannot act like experimental science; a field of possibility has to be conjectured and then tested by the attempt to act upon theorizing.
So Hegel, at least in that Preface, can't be right. And yet, for trying so hard, with such solemnity and scorn for whippersnappers, I still find him very Christmassy. To quote George Oppen, Hegel's "trying to be so good."
