To the mentality that assumes, more or less consciously, that we must of necessity find a solution to every problem, belongs the argument based on the disastrous consequences of a thing. Take any book of apologetics-that is to say, of theological advocacy-and you will see how many times you will meet with this phrase-"the disastrous consequences of this doctrine." Now the disastrous consequences of a doctrine prove at most that the doctrine is disastrous, but not that it is false, for there is no proof that the true is necessarily that which suits us best. -from "The Rationalist Dissolution" This is the masterpiece of Miguel de Unamuno, a member of the group of Spanish intellectuals and philosophers known as the "Generation of '98," and a writer whose work dramatically influenced a wide range of 20th-century literature. His down-to-earth demeanor and no-nonsense outlook makes this 1921 book a favorite of intellectuals to this day, a practical, sensible discussion of the war between faith and reason that consumed the twentieth century and continues to rage in the twenty-first century. de Unamuno's philosophy is not the stuff of a rarefied realm but an integral part of fleshly, sensual life, metaphysics that speaks to daily living and the real world.
