Again, if these designs were found to involve powerful and magnificent results, the immediate belief would follow that the author was wise and powerful as well as benevolent. This illustrates the method by which this implanted principle of reason enables us to learn the design and character of the Author of the universe by the works of creation. The fifth intuitive truth is, that NO RATIONAL MIND WILL CHOOSE EVIL WITHOUT ANY HOPE OF COMPENSATING GOOD. The fact that any person was seeking pain and evil without hope of compensating good would prove to all that "reason was lost." No sane mind ever acts thus. It is by the aid of this intuitive truth that we rely on human testimony. The surest mode of establishing the reliability of a witness is to show that by false testimony he would knowingly incur evil and gain no good. In such circumstances no one would believe that a witness would be false. The sixth intuitive truth is, that THINGS WILL CONTINUE AS THEY ARE AND HAVE BEEN TILL THERE IS EVIDENCE OF A CHANGE OR OF A CAUSE FOR A CHANGE. All the business of this life rests on a belief in this implanted truth, and equally so do our inferences in regard to the immortality of the soul and a future state. The belief that the sun will continue to rise, or that the seasons will return, rests solely on the fact that these events have been uniform in past time, and that we know of no cause for a change from this uniformity. And were any person to talk and act as if destitute of this belief, he would be deemed insane. Bishop Butler's celebrated argument on the immortality of the soul is founded entirely on this principle. It is briefly this: Things will continue as they are and have been unless there is some evidence of some change or cause for a change. At death the soul exists. The dissolution of the body is no evidence of the destruction of the soul, and there is no kind of evidence that it is destroyed. Therefore we infer that the soul continues to exist after the dissolution of the body. The main point in this argument is to show that there is no evidence that the act of death involves the destruction of the soul. If this can be established, then the belief must follow that the soul exists after death. By the same method Butler establishes several other doctrines of the Bible. It is by the aid of this principle that what are called the laws of nature are established. By means of human testimony we learn what has been the uniform course of nature. And then men conclude that what has been will continue to be until some new cause intervenes to change this uniformity. The seventh intuitive truth is, that the NEEDLESS DESTRUCTION OF HAPPINESS OR INFLICTION OF PAIN IS WRONG, and THAT WHATEVER TENDS TO PRODUCE THE MOST HAPPINESS IS RIGHT.
