"In some sense, man must forgo his purely personal preference and submit to the machine before he can achieve good results in the limited province of choice that remains to him. This curtailment of freedom is not unknown even in the pure arts...material and process play this part everywhere." (81)
Indeed, not "unknown" but frequently denied or willfully ignored. The "fundamental vanity" of the infant and the "irrationality" of the savage are archetypes to which Mumford has already appealed, psychological barriers to conscious acceptance of any "curtailment of freedom" as may be threatened. These barriers are presented as pathologies or deviations, failures of normative development; as with so-called Uncommon Sense, the norm is also an achievement, not a given. If there is any sympathy due the vain and irrational, it might be grounded in the observation that many curtailments are simply imposed upon us, accepted on our behalf, or perfectly untransparent to us at pivotal moments. I will forever be envious of trombonists for the potential (not to say the certainty) of the trombone to be both in-tone and in-tune where players of valved brass face ineluctable conflicts between those two ideals. Then again, if as an adolescent this had been explained to me intellectually, I would most certainly have ignored it. Immaturity is at best half the reason why.
