In one of its numerous meanings “mind” has long represented, and popularly still to some extent does represent, a special non-spatial type of entity transcending and ideally complementing the world of matter. More particularly it has stood for an innate “rational faculty” characterizing men as men; an immaterial substance radically differentiating human beings from animals and by the same token serving to bind them to one another, as brothers are bound by the tie of common blood. Thus conceived, mind traditionally has justified, and so strengthened, the ingenuous a priori regard and appreciation which unlearned persons extend to their fellows for the sole reason that they are human. Upon this conception of mind numerous popular doctrines of “personal dignity,” “human equality”, “individual liberty”, “freedom of conscience”, “inalienable rights”, and so forth, have been rationally grounded. And without it as an inspiration—to name but one dependent consequence—“the American dream”, which Adams describes in The Epic of America, would doubtless never have been dreamt.
