If we wish a change to be as deep and radical as possible, we must apply the remedy in minute doses, but unremittingly for long periods. What great action can be performed all at once?
– Friedrich Nietzsche, The Dawn of Day (1881)
When a man turns his back upon someone and walks away, it is easy to see that he walks away, but when a man hits upon a method of turning his face towards the one he is walking away from, hits upon a method of walking backwards while with appearance and glance and salutations he greets the person, giving assurances again and again that he is coming immediately, or incessantly saying “Here I am” although he gets farther and farther away by walking backwards, then it is not easy to become aware.
– Søren Kierkegaard, Works of Love (1847)
