Depend on no man, on no friend but him who can depend on himself. He only who acts conscientiously toward himself, will act so toward others.
— Johann Kaspar Lavater

A soiled baby, with a neglected nose, cannot be conscientiously regarded as a thing of beauty.
Mark Twain conscientiously quote

It is curious how there seems to be an instinctive disgust in Man for his nearest ancestors and relations. If only Darwin could conscientiously have traced man back to the Elephant or the Lion or the Antelope, how much ridicule and prejudice would have been spared to the doctrine of Evolution.
— Havelock Ellis

If, for instance, they have heard something from the postman, they attribute it to a semi-official statement; if they have fallen into conversation with a stranger at a bar, they can conscientiously describe him as a source that has hitherto proved unimpeachable. It is only when the journalist is reporting a whim of his own, and one to which he attaches minor importance, that he defines it as the opinion of well-informed circles.
— Evelyn Waugh

I could not accept the academic idea that the purpose of music was communication, because I noticed that when I conscientiously wrote something sad, people and critics were often apt to laugh. I determined to give up composition unless I could find a better reason for doing it than communication. I found this answer from Gira Sarabhai, an Indian singer and tabla player: The purpose of music is to sober and quiet the mind, thus making it susceptible to divine influences. I also found in the writings of Ananda K. Coomaraswammy that the responsibility of the artist is to imitate nature in her manner of operation. I became less disturbed and went back to work.
