Two puny words shoulder a substantial, if diffuse, philosophical outlook: as if. Epicurus was perhaps the first to put this unexceptional construction to good use. He felt that life was about attaining whatever passing happiness we might find, while avoiding as much pain and suffering as we can. In neither endeavour will we be very successful, but one strategy he suggested was to adopt values that increase our joy and diminish our sorrow, and live as if those values were actually true, though they may not be.
