This article focuses on singularities, that is, rare, abnormal, exceptional, or unusual things throughout the history of Philosophy, science, or arts. Considered in the light of the principle according to which, there is no science of the particular, the singularities, however at the source of many discoveries, have long been ignored or rejected on the side of the Wonders before being, rather belatedly , regarded as the origin of forms, of the very life of the universe. This article reports on this major epistemological reversal.
