Thus such an one will exultingly go forth in the full pride of scientific attainment, esteeming all things as certain when he has ascribed them to the laws of nature; not thinking of the mysterious agency ever at work to maintain those laws. Such a mind has no wonder, because it has no powers to carry it forward into the mysterious and illimitable in the universe. Another feeling of the great mind in view of great objects, is that of simple ignorance. It has gone forth, and seen its own narrow limits, and then it pauses and is humble, conscious how like a child it is. Such are some of the features which a great mind exhibits, and such the results to which it tends, the expression of which is marked by that simplicity of which we have spoken.
