Into the scales of justice a person throws weights from his store of knowledge, and it is his own ideas about the values of things that weigh and balance them. But as opinions change at every step in evolution what may seem just or unjust today is not likely to seem so tomorrow. What a person calls wrong at one time will seem at another time in his life to be right, and it is the same with regard to what at one period of his evolution he considers right. No wonder that the prophets, reformers, and poets have so often contradicted themselves in their writings! One can find contradictions in all the scriptures of the world, and it needs a perfect development of the faculty to look at this idea with a perfect view.
