Thus the process of professional evolution betrays throughout the same traits. In stages like that described by Huc[45] as still existing among the Tibetans, where "the Lama is not merely a priest, he is the painter, poet, sculptor, architect, physician," there are joined in the same individual, or group of individuals, the potentialities out of which gradually arise the specialized groups we know as professions. While out of the one primitive class there come by progressive divergences many classes, each of these classes itself undergoes a kindred change: there are formed in it subdivisions and even sub-subdivisions, which become gradually more marked; so that, throughout, the advance is from an indefinite homogeneity to a definite heterogeneity. [Footnote 45: Evariste Regis Huc, a French missionary and traveler in China, born in 1813 and died in 1860. He published several books based on his experiences in Asia.] In presence of the fact that the immense majority of mankind adhere pertinaciously to the creeds, political and religious, in which they are brought up; and in presence of the further fact that on behalf of their creeds, however acquired, there are soon enlisted prejudices which practically shut out adverse evidence, it is not to be expected that the foregoing illustrations, even joined with kindred illustrations previously given, will make them see that society is a growth and not a manufacture, and has its laws of evolution. From prime ministers down to plowboys there is either ignorance or disregard of the truth that nations acquire their vital structures by natural processes and not by artificial devices. If the belief is not that social arrangements have been divinely ordered thus or thus, then it is that they have been made thus or thus by kings, or if not by kings, then by parliaments. That they have come about by small accumulated changes not contemplated by rulers is an open secret which only of late has been recognized by a few, and is still unperceived by the many,--educated as well as uneducated. Tho the turning of the land into a food-producing surface, cleared, fenced, drained, and covered with farming appliances, has been achieved by men working for individual profit, not by legislative direction--tho villages, towns, cities, have insensibly grown up under the desires of men to satisfy their wants--tho by spontaneous cooperation of citizens have been formed canals, railways, telegraphs, and other means of communication and distribution, the natural forces which have done all this are ignored as of no account in political thinking.
