मनुस्मृति - धर्मिष्टः

आर्षं धर्मोपदेशं च वेदशास्त्राविरोधिना ।
यस्तर्केणानुसंधत्ते स धर्मं वेद नेतारः ॥

- मनुस्मृति

The preachings of sages regarding the moral code of conduct are on one side. The ancient scriptures are the other side. Both supplement each other. But only the person who reconciles both of them with sound logic can be called as "righteous". If not, he would just be another blind follower.
