The Abolition of Man - C. S. Lewis [10]
The truth finally becomes apparent that neither in any operation with factual propositions nor in any appeal to instinct can the Innovator find the basis for a system of values. None of the principles he requires are to be found there: but they are all to be found somewhere else. ‘All within the four seas are his brothers’ (xii. 5) says Confucius of the Chün-tzu, the cuor gentil or gentleman. Humani nihil a me alienum puto says the Stoic. ‘Do as you would be done by,’ says Jesus. ‘Humanity is to be preserved,’ says Locke.4 All the practical principles behind the Innovator’s case for posterity, or society, or the species, are there from time immemorial in the Tao. But they are nowhere else. Unless you accept these without question as being to the world of action what axioms are to the world of theory, you can have no practical principles whatever. You cannot reach them as conclusions: they are premisses. You may, since they can give no ‘reason’ for themselves of a kind to silence Gaius and Titius, regard them as sentiments: but then you must give up contrasting ‘real’ or ‘rational’ value with sentimental value. All value will be sentimental; and you must confess (on pain of abandoning every value) that all sentiment is not ‘merely’ subjective. You may, on the other hand, regard them as rational—nay as rationality itself—as things so obviously reasonable that they neither demand nor admit proof. But then you must allow that Reason can be practical, that an ought must not be dismissed because it cannot produce some is as its credential. If nothing is self-evident, nothing can be proved. Similarly if nothing is obligatory for its own sake, nothing is obligatory at all.
To some it will appear that I have merely restored under another name what they always meant by basic or fundamental instinct. But much more than a choice of words is involved. The Innovator attacks traditional values (the Tao) in defence of what he at first supposes to be (in some special sense) ‘rational’ or ‘biological’ values. But as we have seen, all the values which he uses in attacking the Tao, and even claims to be substituting for it, are themselves
