"I can look back . . . at two distinct periods of opinion whose foundations I have successively come to distrust - a period before 1919 or so, when the weight of classic authority unduly influenced me, and another period from 1919 to about 1925, when I placed too high a value on the elements of revolt, florid colour, and emotional extravagance or intensity."

In his anti-Darwinian book... (and eponymously named The Neck of the Giraffe ), Francis Hitching tells the story... "The need to survive by reaching ever higher for food is, like so many Darwinian explanations of its kind, little more than a post hoc speculation." Hitching is quite correct, but he rebuts a fairy story that Darwin was far too smart to tell - even though the tale later entered our high school texts as a "classic case" nonetheless.
