the imagined effect of this reflection upon
another's mind. This is evident from the fact that the
character and weight of that other, in whose mind we see
ourselves, makes all the difference with our feeling.[56]

Veblen has made a subtle analysis of the way in which conduct is
controlled by the individual's conception of his social role in his
analysis of "invidious comparison" and "conspicuous expenditure."[57]

d) _Biological and social inheritance._--The distinction between
biological and social inheritance is sharply made by the noted
biologist, J. Arthur Thomson, in the selection entitled "Nature and
Nurture." The so-called "acquired characters" or modifications of
original nature through experience, he points out, are transmitted not
through the germ plasm but through communication.

Thorndike's "Inventory of Original Tendencies" offers a detailed
classification of the traits transmitted biologically. Since there
exists no corresponding specific analysis of acquired traits, the
following brief inventory of types of social heritages is offered.

TYPES OF SOCIAL HERITAGES

(a) means of communication, as language, gesture, etc.;
(b) social attitudes, habits, wishes, etc.;
(c) character;
(d) social patterns, as folkways, mores, conventions, ideals,
etc.;
(e) technique;
(f) culture (as distinguished from technique, formal organization,
and machinery);
(g) social organization (primary group life, institutions, sects,
secondary groups, etc.).

On the basis of the work of Mendel, biologists have made marked progress
in determining the inheritance of specific traits of original nature.
The selection from a foremost American student of heredity and eugenics,
C. B. Davenport, entitled "Inheritance of Original Nature" indicates the
precision and accuracy with which the prediction of the inheritance of
individual innate traits is made.

The mechanism of the transmission of social heritages, while more open
to observation than biological inheritance, has not been subjected to as
intensive study. The transmission of the social heritage takes place by
communication, as Keller points out, through the medium of the various
senses. The various types of the social heritages are transmitted in two
ways: (a) by tradition, as from generation to generation, and (b) by
acculturation, as from group to group.

In the communication of the social heritages, either by tr
