These are the two complementary functions proper to the traditional sciences: on the one hand, as applications of the doctrine, they make it possible to link the different orders of reality and to integrate them into the unity of a single synthesis, and on the other, they constitute, at least for some, and in accordance with their individual aptitudes, a preparation for a higher knowledge and a way of approach to it - forming by virtue of their hierarchical positioning, according to the levels of existence to which they refer, so many rungs as it were by which it is possible to climb to the level of pure intellectuality.
It is only too clear that modern sciences cannot in any way serve either of these purposes; this is why they can be no more than 'profane science', whereas the 'traditional sciences', through their connection with metaphysical principles, are effectively incorporated in 'sacred science'.
The ways leading to knowledge may be extremely different at the lowest degree, but they draw closer and closer together as higher levels are reached. This is not to say that any of these preparatory degrees are absolutely necessary, since they are mere contingent methods having nothing in common with the end to be attained; it is even possible for some persons, in whom the tendency to contemplation is predominant, to attain directly to true intellectual intuition without the aid of such means; but this is a more or less exceptional case, and in general it is accepted as being necessary to proceed upward gradually.
The whole question may also be illustrated by means of the traditional image of the 'cosmic wheel': the circumference in reality exists only in virtue of the center, but the beings that stand upon the circumference must necessarily start from there or, more precisely, from the point thereon at which they actually find themselves, and follow the radius that leads to the center. Moreover, because of the correspondence that exists between all the orders of reality, the truths of a lower order can be taken as symbols of those of higher orders, and can therefore serve as 'supports' by which one may arrive at an understanding of these; and this fact makes it possible for any science to become a sacred science, giving it a higher or 'anagogical' meaning deeper than that which it possesses in itself.
Every science, we say, can assume this character, whatever may be its subject-matter, on the sole condition of being constructed and regarded from the traditional standpoint; it is only necessary to keep in mind the degrees of importance of the various sciences according to the hierarchical rank of the diverse realities studied by them; but whatever degree they may occupy, their character and functions are essentially similar in the traditional conception.
What is true of the sciences is equally true of the arts, since every art can have a truly symbolic value that enables it to serve as a support for meditation, and because it’s rules, like the laws studied by the sciences, are reflections and 'applications of fundamental principles: there are then in every normal civilization 'traditional arts', but these are no less unknown to the modern West than are the 'traditional sciences'. The truth is that there is really no 'profane realm' that could in any way be opposed to a 'sacred realm'; there is only a 'profane point of view', which is really none other than the point of view of ignorance.
This is why 'profane science', the science of the moderns, can as we have remarked elsewhere be justly styled 'ignorant knowledge', knowledge of an inferior order confining itself entirely to the lowest level of reality, knowledge ignorant of all that lies beyond it, of any aim more lofty than itself, and of any principle that could give it a legitimate place, however humble, among the various orders of knowledge as a whole. Irremediably enclosed in the relative and narrow realm in which it has striven to proclaim itself independent, thereby voluntarily breaking all connection with transcendent truth and supreme wisdom, it is only a vain and illusory knowledge, which indeed comes from nothing and leads to nothing.
This survey will suffice to show how great is the deficiency of the modern world in the realm of science, and how that very science of which it is so proud represents no more than a deviation and, as it were, a downfall from true science, which for us is absolutely identical with what we have called 'sacred' or 'traditional' science. Modern science, arising from an arbitrary limitation of knowledge to a particular order-the lowest of all orders, that of material or sensible reality-has lost, through this limitation and the consequences it immediately entails, all intellectual value; as long, that is, as one gives to the word 'intellectuality' the fullness of its real meaning, and refuses to share the 'rationalist' error of assimilating pure intelligence to reason, or, what amount to the same thing, of completely denying intellectual intuition.
The root of this error, as of a great many other modern errors - and the cause of the entire deviation of science that we have just described - is what may be called 'individualism', an attitude indistinguishable from the anti-traditional attitude itself and whose many manifestations in all domains constitute one of the most important factors in the confusion of our time; we shall therefore now study this individualism more closely.
