The Folarians (such was their name) were a pacifistic people who believed in free will, free thought, free love, free land, free living, free rides, freeloading and freebies of all kinds. Bitter enemies of the Vegetarians, the Fruitarians (who lived exclusively on raw fruit), the Pietarians (or “New Fruitarians,” as they were sometimes called, who ate only raw fruit pies) and the Breatharians (who subsisted on air alone), the Folarians promoted a doctrine wherein eternal life was achieved by abstaining from all food sources save foliage—thus their name. Moreover, this foliage—whether leaves, stems or flowers—must already have fallen to the ground of its own accord. This way, eating only nature’s leftovers, the Folarians lived in perfect harmony with Mother Earth.
