That we do not simply stand within these boundaries, but by virtue of our awareness of them have passed beyond them—this is the sole consideration which can save us from despair over them, over our limitations and finitude. That we are cognizant of our knowing and our not-knowing, and are likewise aware of this broader cognizance, and so forth into the potentially endless—this is the real infinity of vital movement on the level of intellect.

Georg Simmel, on individuality and social…, loc. 795
