These two categories of knowledge, or of _cognoscenda_, are incongruous, of course, and they seem incompatible when applied to the same phenomena, the same external objects. But such incongruity does not disturb anyone who is at all content to take facts at their face value,--for both ways of apprehending the facts are equally given in the face value of the facts apprehended. And on the known lower levels of culture it appears that in the workman’s apprehension of the facts with which he has to do there is no evident strain due to this twofold nature and twofold interpretation of the objects of knowledge. So, for instance, the Pueblo potter (woman) may (putatively) be aware of certain inherent, quasi-spiritual, pragmatic qualities, claims and proclivities personal to the clay beds from which her raw material is drawn: different clay beds have, no doubt, a somewhat different quasi-personality, which has, among other things, to do with the goodness of the raw material they afford. Even the clay in hand will have its pragmatic peculiarities and idiosyncracies which are duly to be respected; and, notably, the finished pot is an entity with a life-history of its own and with temperament, fortunes and fatalities that make up the substance of good and evil in its world.[28] But all that does not perceptibly affect the technology of the Pueblo potter’s art, beyond carrying a sequence of ceremonial observance that may run along by the side of the technological process; nor does it manifestly affect the workmanlike use of the pot during its lifetime, except that the pragmatic nature of the given pot will decide, on grounds of ceremonial competency, to what use it may be put.[29] Matter of fact and matter of imputation run along side by side in inextricable contact but with slight apparent mutual interference across the line. The potter digs her clay as best she has learned how, and it is a matter of workmanlike efficiency, in which empirical knowledge of the mechanical qualities of the material is very efficiently combined with the potter’s trained proficiency in the discretionary use of her tools; the tools, of course, also have their (putative) temperamental idiosyncracies, but they are employed in her hands in uncritical conformity with such matter-of-fact laws of physics as she has learned. The clay is washed, kneaded and tempered with the same circumspect regard to the opaque facts known about clay through long handling of it. What and how much tempering material may best be used, and how it is to be worked in, may all have a recondite explanation in the subtler imputed traits of the clay; a certain clay may have a putative quasi-spiritual affinity for certain tempering material; but the work of selection and mixing is carried out with a watchful regard to the mechanical character of the materials and without doubt that the given materials will respond in definite, empirically ascertained ways to the
