-Frost, Robert Lee
  'Ten Mills,1. Precaution'.

The charge that an idea is radical, impractical, or long- haired is met by showing that a prominent businessman has favored it†an additional tactic in this strategy of defense†is to assert that Winston Churchill once sponsored the particular idea. If one is challenged, a sufficiently careful investigation will show that he did.

-Galbraith,John Kenneth
  Economics and the Art of Controversy.

A conservative is a man with two perfectly good legs who hasnever learned towalk forwards. A reactionary is a somnambulist walking backwards. A radical is a man with both feet planted firmly in the air.

-Roosevelt, Franklin D(elano)

Radical chic invariably favors radicals who seem primitive, exotic and romantic.
