A man -- a viewing-point man -- while he will love the abstract good qualities and detest the abstract bad, will nevertheless envy and admire the person who through possessing the bad qualities has succeeded economically and socially, and will hold in contempt that person whose good qualities have caused failure. When such a viewing-point man thinks of Jesus or St. Augustine or Socrates he regards them with love because they are the symbols of the good he admires, and he hates the symbols of the bad. But actually he would rather be successful than good. In an animal other than man we would replace the term "good" with "weak survival quotient" and the term "bad" with "strong survival quotient." Thus, man in his thinking or reverie status admires the progression toward extinction, but in the unthinking stimulus which really activates him he tends toward survival. Perhaps no other animal is so torn between alternatives. Man might be described fairly adequately, if simply, as a two-legged paradox. He has never become accustomed to the tragic miracle of consciousness: Perhaps, as has been suggested, his species is not set, has not jelled, but is still in a state of becoming, bound by his physical memories to a past of struggle and survival, limited in his futures by the uneasiness of thought and consciousness.

 John Steinbeck,  The Log from the Sea of Cortez

It ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things. Because the innovator has for enemies all those who have done well under the old conditions, and lukewarm defenders in those who may do well under the new. This coolness arises partly from fear of the opponents, who have the laws on their side, and partly from the incredulity of men, who do not readily believe in new things until they have had a long experience of them.
