superseded Hippokrates and Galen: yet, on the negative side and particularly in metaphysics, definite progress has been made.
Descartes' Cogito ergo sum —'I think; therefore I exist' —has been criticized not because its assumptions are top modest, but because they are too large. Logically it can be reduced to cogito, and even that has been shorn of the implied ego. That is to say, the momentary fact of consciousness is the only reality that cannot logically be doubted; for the mere act of doubting, being an act of consciousness, is of itself immediate proof of the existence of that which was to be the object of doubt.
Consciousness is therefore the fundamental reality, and all metaphysical systems or dogmas which found themselves on any other basis are demonstrably fantastic. In particular, materialistic philosophies of every kind and degree are fantastic.
But, because demonstrably fantastic, they are not therefore demonstrably false. We cannot, for instance, be reasonably driven to admit that some external substance called 'matter' is prior to or condition of consciousness; but just as little can we reasonably deny the possibility of such a state of th ings. For, logically, denial is as inadmissible as assertion, when we face the ultimate problems of existence outside the strait moment of consciousness which is all that certainly remains to us after the Cartesian analysis. Descartes, it is true, did not leave it at that. But he had cleared the way for Hume and Kant to show that, briefly, every assumption which he himself or any other metaphysician might produce like a rabbit from the hat must have been put into the hat before being brought out. In other words, the scientific method, applied to these problems and pressed to its logical implications, leads to an agnosticism which must go to the whole of experience, as Pyrrho's did, and not arbitrarily stop short at selected limits, as did the agnosticism of the nineteenth century. It leads, therefore, to an attitude of complete and speechless scepticism.
If we think this conclusion a reductio ad absurdum, and would seek yet some touchstone for the false and the true, we must seek it elsewhere than in pure reason. That is to say (confining the argument to serious attitudes of speculation on the ultimate problems of existence), we must at that stage abandon the scientific attitude and adopt the poet's. By the poet's I mean that attitude which says that ultimate truths are to be attained, if at all, in some immediate way: by vision rather than by ratiocination.
How, then, is the poet to go to work, voyaging now in alternate peril of the Scylla and Charybdis which the Cartesian-Kantian criticism has laid bare—the dumb impotence of pure reason on the one hand, and on the other a welter of disorganized fantasy through which reason of itself is powerless to choose a way, since to reason (in these problems) 'all things are possible' and no fantasy likelier than another to be true?
Reason, as we have seen, reached a certain bed-rock, exiguous but unshakable, by means of a criticism based on credibility: it cleared away vast superfluities of baseless system and dogma by divesting itself of all beliefs that it was possible to doubt. In the same way, may it not be possible to reach a certain bed-rock among the chaos of fantasy by means of a criticism based not on credibility but on value?
No conscious being, we may suppose, is without desire; and if certain philosophies and religions have set up as their ideal of salvation and beatitude a condition of desirelessness, to be attained by an asceticism that stifles and starves every desire, this is no more than to say that those systems have in fact applied a criticism of values to dethrone all minor values, leaving only this state of blessedness which (notwithstanding their repudiation of desire) remains as (for their imagination at least) the one thing desirable. And in general, it can be said that no religion, no philosophy, no
