«Science in the works has two aspects: what could be called day science and night science. Day science employs reasoning that meshes like gears, and achieves results with the force of certainty.....

Night science, on the other hand, wanders blindly....... What guides the mind, then, is not logic. It is instinct, intuition. It is the need to see clearly. It is the stubborn desire to live. In the endless interior dialogue, among the innumerable suppositions, connections, combinations, associations that constantly pass through the mind, a beam of light sometimes rends the obscurity.»
