Sincerity is the way of Heaven. The attainment of sincerity is the way of men. He who possesses sincerity is he who, without an effort, hits what is right, and apprehends, without the exercise of thought - he is the sage who naturally and easily embodies the right way. He who attains to sincerity is he who chooses what is good, and firmly holds it fast. To this attainment there are requisite the extensive study of what is good, accurate inquiry about it, careful reflection on it, the clear discrimination of it, and the earnest practice of it.
