Excerpt from The American Presbyterian and Theological Review, 1863, Vol. 1 Is there an external world? Certainly, says Dr. Hickok, there is such a reality, beyond all question. Certainly, says Dr. Hallf - nu external world there is, and of hard matter too; are we not every day coming in contact with it? But how do we know it that is, how do we know it as external? Here is another question, and on this they differ. How do we know it, says Dr. Hickok; Why, we know it from our rea son. It stands to reason that there is something outside of us, when there are effects produced within us of which we are conscious, but which we are sure did not come from any will ing, or any internal self-originated activity of our own. The reason, as a higher comprehending, overlooking faculty, com prehends the one universal time and space which never could have been found in the chaotic sea of individual sensations.
