Lao Tzu (6th and 5th Century BCE Daoist theologian and philosopher)
“In the world there is nothing more submissive and weak
than water. Yet for attacking that which is hard and strong
nothing can surpass it.”
- From Lao Tzu’s Tao Te Ching (Book Two, LXXVIII), translated by D. C. Lau (Penguin Classics edition, 1963).
