Yet in speaking of the light of faith, we can almost hear the objections of many of our contemporaries. In modernity, that light might have been considered sufficient for societies of old, but was felt to be of no use for new times, for a humanity come of age, proud of its rationality and anxious to explore the future in novel ways. Faith thus appeared to some as an illusory light, preventing mankind from
PAINTING: G. ROUAULT boldly setting out in quest of knowledge. The young Nietzsche encouraged his sister Elisabeth to take risks, to tread "new paths… with all the uncertainty of one who must find his own way", adding that "this is where humanity’s paths part: if you want peace of soul and happiness, then believe, but if you want to be a follower of truth, then seek". Belief would be incompatible with seeking. From this starting point Nietzsche was to develop his critique of Christianity for diminishing the full meaning of human existence and stripping life of novelty and adventure. Faith would thus be the illusion of light, an illusion which blocks the path of a liberated humanity to its future.
In the process, faith came to be associated with darkness. There were those who tried to save faith by making room for it alongside the light of reason. Such room would open up wherever the light of reason could not penetrate, wherever certainty was no longer possible. Faith was thus understood either as a leap in the dark, to be taken in the absence of light, driven by blind emotion, or as a subjective light, capable perhaps of warming the heart and bringing personal consolation, but not something which could be proposed to others as an objective and shared light which points the way. Slowly but surely, however, it would become evident that the light of autonomous reason is not enough to illumine the future; ultimately the future remains shadowy and fraught with fear of the unknown. As a result, humanity renounced the search for a great light, Truth itself, in order to be content with smaller lights which illumine the fleeting moment yet prove incapable of showing the way. Yet in the absence of light everything becomes confused; it is impossible to tell good from evil, or the road to our destination from other roads which take us in endless circles, going nowhere.
