But the experience which yields this useful and pseudo-useful knowledge is got under the impulsion and guidance of one and another of the instincts with which man is endowed, and takes the shape and color given it by the instinctive bias in whose service it is acquired. At the same time, whatever its derivation, the knowledge acquired goes into the aggregate of information drawn on for the ways and means of workmanship. Therefore the habits formed in any line of experience, under the guidance of any given instinctive disposition, will have their effect on the conduct and aims of the workman in all his work and play; so that progress in technological matters is by no means an outcome of the sense of workmanship alone. It follows that in all their working the human instincts are in this way incessantly subject to mutual “contamination,” whereby the working of any one is incidentally affected by the bias and proclivities inherent in all the rest; and in so far as these current habits and customs in this way come to reënforce the predispositions comprised under any one instinct or any given group of instincts, the bias so accentuated comes to pervade the habits of thought of all the members of the community and gives a corresponding obliquity to the technological groundwork of the community. So, for instance, addiction to magical, superstitious or religious conceptions will necessarily have its effect on the conceptions and logic employed in technological theory and practice, and will impair its efficiency by that much. A people much given to punctilios of rank and respect of persons will in some degree carry these habitual predilections over into the field of workmanship and will allow considerations of authenticity, of personal weight and consequence, to decide questions of technological expediency; so that ideas which have none but a putative efficiency may in this way come in for a large share in the state of the industrial arts. A people whose culture has for any reason taken on a pronounced coercive (predatory) character, with rigorous class distinctions, an arbitrary governmental control, formidable gods and an authoritative priesthood, will have its industrial organisation and its industrial arts fashioned to meet the demands and the logic of these institutions. Such an institutional situation exerts a great and pervasive constraint on the technological scheme in which workmanship takes effect under its rule, both directly by prescribing the things to do and the time, place and circumstance of doing them, and indirectly through the habits of thought induced in the working population living under its rule. Innovation, the utilisation of newly acquired technological insight, is greatly hindered by such institutional requirements that are enforced by other impulses than the sense of workmanship.
