The one-sidedness, inherent in the education for one calling, stamps man with a peculiar character. A clergyman or a schoolmaster is generally and easily recognized by his carriage and mien; likewise an officer, even when in civilian dress. A shoe maker is easily told from a tailor, a joiner from a locksmith. Twin brothers, who closely resembled each other in youth, show in later years marked differences if their occupations are different, if one had hard manual work, for instance, as a smith, the other the study of philosophy for his duty. Heredity, on one side, adaptation on the other, play in the development of man, as well as of animals, a decisive _role_. Indeed, man is the most bending and pliable of all creatures. A few years of changed life and occupation often suffice to make quite a different being out of the same man. Nowhere does rapid external change show itself more strikingly than when a person is transferred from poor and reduced, to materially improved circumstances. It is in his mental make-up that such a person will be least able to deny his antecedents, but that is due to the circumstance that, with most of such people, after they have reached a certain age, the desire for intellectual improvement is rarely felt; neither do they need it. Such an upstart rarely suffers under this defect. In our days, that look to money and material means, people are far readier to bow _before the man with a large purse, than before a man of knowledge and great intellectual gifts, especially if he has the misfortune of being poor and rankless_. Instances of this sort are furnished every day. The worship of the golden calf stood in no age higher than in this,--whence it comes that we are living "in the best possible world."
