A true conscience is not one that never needs to be corrected. On the contrary, the conscience grows in purity as it discovers more impurities. Its accuracy is measured by its demands and rigors. No one can apply himself assiduously to the meditation of the Gospel without noting with sorrow the distance between him and the ideal he is pursuing. We have already said that certain imperfections of conduct are unfortunately combined with a sincere wish to be good. From this contradiction is born the remorse that stimulates our progress.
