The Demon-Haunted World: Science As A Candle In The Dark
by
Carl Sagan

Science is not only compatible with spirituality; it is a profound source of spirituality. when we recognize our place in an immensity of light-years and in the passage of ages, when we grasp the intricacy, beauty and subtlety of life, then that soaring feeling, that sense of elation and humility combined, is surely spiritual. p. 29

When man has so far corrupted and prostituted the chastity of his mind, as to subscribe his professional belief to things he does not believe, he has prepared himself for the commission of every other crime. p. 207

The cure for the fallacious argument is a better argument not the suppression of ideas. p. 429
