War is so unjust and ugly that all who wage it must try to stifle the voice of conscience within themselves. Leo Tolstoy
The voice of conscience is so delicate that it is easy to stifle it; but it is also so clear that it is impossible to mistake it. Anne Louise Germaine de Staël
We should listen to the voice of conscience. It does not take nearly as much courage as one might think to admit to our mistakes and learn from them. Human beings are in this world to learn and to change themselves in learning. Traudl Junge
... There's a joy, To the fond votaries of fame unknown, To hear the still small voice of conscience speak In whisp'ring plaudit to the silent soul. Hannah More
The human voice can never reach the distance that is covered by the still small voice of conscience. Mahatma Gandhi
