Mencius - Book 7, Part 1, Chapter 8

Mencius said, 'The able and virtuous monarchs of antiquity loved virtue and forgot their power. And shall an exception be made of the able and virtuous scholars of antiquity, that they did not do the same? They delighted in their own principles, and were oblivious of the power of princes. Therefore, if kings and dukes did not show the utmost respect, and observe all forms of ceremony, they were not permitted to come frequently and visit them. If they thus found it not in their power to pay them frequent visits, how much less could they get to employ them as ministers?'
