That's here. That's home. That's us. On it, everyone you ever heard of, every human being who ever lived, lived out their lives. The aggregate of all our joys and sufferings, thousands of confident religions, ideologies and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilizations, every king and peasant, every young couple in love, every hopeful child, every mother and father, every inventor and explorer, every teacher of morals, every corrupt politician, every superstar, every supreme leader, every saint and sinner in the history of our species, lived there – on a mote of dust, suspended in a sunbeam. --Carl Sagan
The Greek word from which we derive our word "heresy" is hairesis, which in simplistic terms means a distinctive, personally chosen opinion. . . . Nowadays, the word is used to denote a view or belief that is beyond the pale of orthodoxy or outside the mainstream of thought. As a general rule, it is a pejorative, used to identify thoughts or ideas that are perceived to be illegitimate or pernicious.
