What tone does the author create by referring to himself as "a butterfly
chaser, googly eyed bleeding heart, and wild conservative"?
One should admit at the outset to a certain bias. Indeed I
am a "butterfly chaser, googly eyed bleeding heart and wild
conservative." I take a dim view of dams; I find it hard to
learn to love cement; I am poorly impressed by concrete
aggregates and statistics in the cubic tons. But in this
weakness I am not alone, for I belong to that ever-growing
number of Americans, probably a good majority now, who
have become aware that a fully industrialized, thoroughly
urbanized, elegantly computerized social system is not
suitable for human habitation. Great for machines, yes. But
unfit for people.
