Cuando se lucha contra monstruos hay que tener cuidado de no convertirse en mostruo uno mismo. Si hundes demasiado tiempo tu mirada en el abismo, el abismo acaba por penetrar en ti.
Arrogance as the last means of comfort. If a man accounts for a misfortune, or his intellectual inadequacies, or his illness by seeing them as his predetermined fate, his ordeal, or mysterious punishment for something he had done earlier, he is thereby making his own nature interesting, and imagining himself superior to his fellow men. The proud sinner is a familiar figure in all religious sects.
Conviction is the belief that in some point of knowledge one possesses absolute truth. Such a belief presumes, then, that absolute truth exists; likewise, that the perfect methods for arriving at them have been found; finally, that every man who has convictions makes use of these perfect methods. All three assertions prove at once that the man of convictions is not the man of scientific thinking; he rands before us still in the age of theoretical innocence, a child, however grow-up he might be otherwise.
Friedrich Nietzsche, “Man Alone with Himself”.
Whoever thinks more deeply knows that he is always wrong, whatever his acts and judgments.
