San Miguel De Unamuno

But the truth is that my work--my mission, I was about to say--is to shatter the faith of men, left, right, and center, their faith in affirmation, their faith in negation, their faith in abstention, and I do so from faith in faith itself. My purpose is to war on all those who submit, whether to Catholicism, or to rationalism, or to agnosticism. My aim is to make all men live a life of restless longing.

~ Unamuno, The Tragic Sense of Life, p. 349.
