Change is always subjective. All through evolution you find that the conquest of nature comes by change in the subject. Apply this to religion and morality, and you will find that the conquest of evil comes by the change in the subjective alone. That is how the Advaitic system gets its whole force, on the subjective side of man.
The intelligent person is not one who merely knows what is good and what is bad. The intelligent person is one who, when he sees what is good, follows it, and when he sees evil, shuns it.

Many a reformer perishes in his removal of rubbish,--and that makes the offensiveness of the class. They are partial; they are notequal to the work they pretend. They lose their way; in the assault on the kingdom of darkness, they expend all their energy on some accidental evil, and lose their sanity and power of benefit.
