By this time the advocate had cut into the heart of his subject. In a few swift yet unemphasized sentences he had proved the existence of a doubt in the case. He pressed home the significance of that fact with a power that was so perfectly disciplined that it did not appear to exert itself, yet it carried a qualm into the camp of the enemy. He was content to indicate that the doubt was there, and with apparent magnanimity differentiated it from that which in his view must ever accompany circumstantial evidence. Every gesture that he used in the demonstration of its presence, each vibration of a voice which had become marvellously flexible, was a living witness of the dynamic quality he had in his possession. “He will be wise to let it go at that,” was the opinion of Mr. Weekes. “He has done quite as well as was to have been expected. We shall just get home, and for a beginner he will have done very nicely.” “It wouldn’t surprise me if he is only just starting,” said Mr. Topott mournfully. “I have done now, gentlemen,” Northcote continued, “with the legal aspect of this case. That aspect, as I have shown, makes an acquittal necessary. But whenever we are content to base our judgment upon technicalities, we tie our hands. We furnish room for one of those sophistries which trained intellects, the intellects of those who are far more learned in the law than we are, find it so easy to introduce. There is always the danger that a body of laymen, however unimpeachable their integrity, may be led from the plain and obvious path of their duty by a cunning stratagem. Again, in all those matters that seek ascertained fact for their basis, we must not forget that its supply is partial. Science is doing stupendous things for the world, but even it cannot yet supply mankind with anything beyond half-truths. There is no field of man’s activities--philosophy, religion, politics, law--which does not depend upon these. Science can furnish us with sufficient evidence to hang a fellow creature, but the time is at hand when it will also have furnished us with such abundant knowledge of our eternal fallibility, that we shall cease to exact these reprisals. For are not all reprisals, which we include under the comprehensive term ‘justice,’ the fruit of an imperfect apprehension of the nature of man? It has been said truly that a little knowledge is dangerous, for in looking at the history of human opinion in all the phases through which it has passed, we see how the habit of basing our actions upon half-truths has been the cause of the manifold wounds of the world.
