Over against the statement that people cannot see things alike, I put the indisputable statement that they cannot possibly see things _unlike_ if they see them at all. Every person on earth sees red as red, unless, indeed, he is color blind, and then he does not see it at all, in the proper sense of the word. Two and two make four to every mind in the universe. Given the same premises, every logical mind will come to the same conclusion and cannot possibly come to any other conclusion. The whole law and order of the universe is based upon this fact, and without it no science or order would be possible. We will discover that the differences of opinion among men are not to be ascribed to the intellect so much as to the will and sensibilities. We wish to refer now to a chief cause of division of opinion, and the only one that involves blame; viz.: the human will. Multitudes of people are divided who see things alike and are of the same opinion so far as the intellect is concerned, but the trouble lies in the will power. They deliberately do that which they know is not right, for selfish reasons. If this were the only cause of division, our problem would be an easy one. For then the only proper attitude of the righteous towards those who differ from them, would be that of unqualified opposition. Indeed, we are always tempted to act on this basis by trusting in ourselves that we are right, and treating those who differ from us as wrong and guilty and as deserving nothing but our condemnation. If guilt were the only cause of division, we would have but two political parties, the one containing all the righteous and the other all the wicked. From a religious standpoint there would be but two classes; viz., saints and sinners. But the problem before us is not such an easy one. The causes that lead to differences of opinion are numerous and complex. It is not an easy matter to get at the truth, although we might think at first thought that it is. Every one seems to be surrounded by an atmosphere that reflects, refracts, bends, twists, distorts and colors the rays of truth as they come to him. Neither age, talent, experience, education, piety nor honesty make a man error-proof; as may be readily discovered even by a child. For the people around us who possess these qualities are divided among all the different religious and political parties. And when people are divided into different parties, that teach contradictory doctrines, they cannot possibly all be right, although they may all be wrong. Inquiring more particularly into the causes of division of opinion, aside from guilt, we shall discover the following to be among them: finite, limited faculties, limited and false ideas, obtained through heredity and ignorance, preconceived ideas and prejudices.
