“ Anyone who breaks new paths and who has led many others onto new paths, discovers with some amazement how clumsy and poor these people are in their capacity for expressing gratitude—and how rarely gratitude achieves expression at all It almost seems that whenever gratitude wants to speak, she begins to gag, clears her throat, and falls silent before she has got out a word. ”
 Friedrich Nietzsche, The Gay Science (1882). copy citation
