No, he didn’t give the source. Confucius have books attributed to him, a source would include the book and a precise location. It’s seems indeed misattributed.

For example: « The people may be made to follow a path of action, but they may not be made to understand it. » Analects, VIII, 9. [1]

Also Confucius didn’t speak nor write English, which didn’t exist at the the time, so it’s better to give the translator name when there is various interpretations. (James Legge in this case).
