The horizon is what makes philosophy such a perpetually humiliating discipline. Schopenhauer said it most succinctly: “Every man takes the limits of his own field of vision for the limits of the world.” Nietzsche also spoke of the horizon myriad times in myriad ways, but always with fathomless irony: “One day we reach our goal — and now we point with pride to the long journeys we took to reach it. In truth we did not notice we were traveling. But we got so far because at each point we believed we were at home.”
