 Nicholas then proposes some geometrical “exercises” to provide his readers some object lessons designed to teach how we might reach for the unlimited even while we are aware that we cannot grasp what the infinite God may be. For instance, we are to imagine a circle and a straight line or tangent that meets the circle. From a certain perspective, as the diameter or circumference of the circle increases, its circumference approaches the straight line and appears less and less curved. If we then imagine and extrapolate the circumference to the infinite, we can almost “see” that both straight tangent and curved circumference should coincide—a kind of “coincidence of opposites” that is a figure of how we may think beyond limited things toward the transcendent One. All this is mathematically impossible, of course, but it demonstrates some metaphorical steps for moving beyond the finite toward the infinite that might be transferred from geometrical figures to created beings and their Creator.
