Hegel

“One word more about giving instruction as to what the world ought to be. Philosophy in any case always comes on the scene too late. As the thought of the world, philosophy makes its first appearance at a time When the actual fact has consummated its process of formation, and is now fully matured ... When philosophy paints its grey in grey, a shape of life has meanwhile grown old. And though philosophy can bring it into knowledge, it cannot make it young again. The owl of Minerva does not start upon its flight, until the evening twilight has begun to fall.” (p.20) - Hegel, Philosophy of Right
