To do this is, above all, to grasp what human will and human reason can do, and what they cannot. How can this be known? Not by a specific enquiry and discovery, but by an awareness, not necessarily explicit or conscious, of certain general characteristics of human life and experience. And the most important and most pervasive of these is the crucial line that divides the ‘surface’ from the ‘depths’ – on the one hand the world of perceptible, describable, analysable data, both physical and psychological, both ‘external’ and ‘inner’, both public and private, with which the sciences can deal, although they have in some regions – those outside physics – made so little progress; and, on the other hand, the order which, as it were, ‘contains’ and determines the structure of experience, the framework in which it – that is, we and all that we experience – must be conceived as being set, that which enters into our habits of thought, action, feeling, our emotions, hopes, wishes, our ways of talking, believing, reacting, being. We – sentient creatures – are in part living in a world the constituents of which we can discover, classify and act upon by rational, scientific, deliberately planned methods; but in part (Tolstoy and Maistre, and many thinkers with them, say much the larger part) we are immersed and submerged in a medium that, precisely to the degree to which we inevitably take it for granted as part of ourselves, we do not and cannot observe as if from the outside; cannot identify, measure and seek to manipulate; cannot even be wholly aware of, inasmuch as it enters too intimately into all our experience, is itself too closely interwoven with all that we are and do to be lifted out of the flow (it
Nevertheless, though we cannot analyse the medium without some (impossible) vantage-point outside it (for there is no ‘outside’), yet some human beings are better aware – although they cannot describe it – of the texture and direction of these ‘submerged’ portions of their own and everyone else’s lives; better aware of this than others who either ignore the existence of the all-pervasive medium (the ‘flow of life’), and are rightly called superficial; or else try to apply to it instruments – scientific, metaphysical – adapted solely to objects above the surface, the relatively conscious, manipulable portion of our experience, and so achieve absurdities in their theories and humiliating failures in practice. Wisdom is ability to allow for the (at least by us) unalterable medium in which we act – as we allow for the pervasiveness, say, of time or space, which characterises all our experience; and to discount, less or more consciously, the ‘inevitable trends’, the ‘imponderables’, the ‘way things are going’. It is not scientific knowledge, but a special sensitiveness to the contours of the circumstances in which we happen to be placed; it is a capacity for living without falling foul of some permanent condition or factor which cannot be either altered, or even fully described or calculated; an ability to be guided by rules of thumb – the ‘immemorial wisdom’ said to reside in peasants and other ‘simple folk’ – where rules of science do not, in principle, apply. This inexpressible sense of cosmic orientation is the ‘sense of reality’, the ‘knowledge’ of how to live.
