THE DESCENT OF MAN.

“ which, by continued transmission and accumulation* 
“ have become in us certain faculties of moral intuition — •

to mention the various dispositions and habits trans- 
mitted by many of our domestic animals, I have heard 
of cases in which a desire to steal and a tendency to lie 
appeared to run in families of the upper ranks; and 
as stealing is so rare a crime in the wealthy classes* 
we can hardly account by accidental coincidence for the 
tendency occurring in two or three members of the 
same family. If bad tendencies are transmitted, it is 
probable that good ones are likewise transmitted. Ex- 
cepting through the principle of the transmission of 
moral tendencies, we cannot understand the differences 
believed to exist in this respect between the various 
races of mankind. We have, however, as yet, hardly 
sufficient evidence on this head. 
Even the partial transmission of virtuous tendencies 
would be an immense assistance to the primary impulse 
derived directly from the social instincts, and indirectly 
from the approbation of our fellow-men. Admitting 
for the moment that virtuous tendencies are inherited, 
it appears probable, at least in such cases as chastity* 
temperance, humanity to animals, &c., that they become 
first impressed on the mental organisation through 
habit, instruction, and example, continued during several 
generations in the same family, and in a quite subor- 
dinate degree, or not at all, by the individuals pos-
