More and more it seems to me that the philosopher, being of necessity a man of tomorrow and the day after tomorrow, has always found himself, and had to find himself, in contradiction to his today: his enemy was ever the ideal of today. So far all these extraordinary furtherers of men whom one calls philosophers, though they themselves have rarely felt like friends of wisdom but rather like disagreeable fools and dangerous question marks, have found their task, their hard, unwanted, inescapable task, but eventually also the greatness of their task, in being the bad conscience of their time.

Act without doing; work without effort. Think of the small as large and the few as many. Confront the difficult while it is still easy; accomplish the great task by a series of small acts.

For this reason sages never do what is great, and this is why they achieve greatness.
