A reasonable watchfulness against conformity will not lead a man to spurn the aid of other men, still less to reject the accumulated mental capital of ages. It does not compel us to dote upon the advantages of savage life. We would not forego the hard-earned gains of civil society because there is something in most of them which tends to contract the natural powers, although it vastly aids them. We would not, for instance, return to the monosyllabic utterance of barbarous men, because in any formed language there are a thousand snares for the understanding. Yet we must be most watchful of them.
