superior knowledge in the science of mind. If the Gospel had never reached us we would have been as great dreamers in mental science as the mystics of India. The doctrine of one Creator, who is a perfect spirit, and the father of our spirits, and that he presides over all nature for the good of the whole; that matter is inert, and moves not unless as it is moved; that all life and force is in mind or spirit; that all spirits are free agents, and act from choice; that all spirits have the same essential attributes; and that man is of the divine "_genos_" kind or sort, and, as an intellectual being, is therefore in the image of God, has simplified and extended our researches in the science of mind, and based them on reason and common sense as well as revelation. From such considerations the doctrine of universal brotherhood has proceeded along with the equal, civil, political and religious rights of all mankind. The ultimate fruit of all is the abolition of oppression and slavery throughout the world, and the desire to see all men elevated to their proper rank as intellectual and moral beings. Thus our views of God and nature, of mind and matter, are of immense practical value to our race. Do you say mind or spirit does not belong as a real factor to science? Well, we are astonished! Science is correct, or certain knowledge arising from a deep and rational inquiry into the object or subject of investigation. The question therefore comes back again, have we any knowledge of mind? This is to ask, whether consciousness is knowledge! The term comes from the Latin "_con_," which signifies together, and "_scio_," I know, and is used to convey the idea that we know the thing altogether, that is, have perfect or full knowledge. It is the mind's testimony concerning itself. Now, if I can become acquainted with external and material objects through my senses, certainly my consciousness of my own mental operations is, and must be, more certain and self-evident. In judging, reasoning, reflecting, choosing, desiring, remembering, loving, hating and hoping, along with all other operations of mind, I must know the operation intimately, perfectly and altogether. If I am reflecting, I know it, and this consciousness is science, is certain knowledge, is the very thing from which no man can escape so long as he is a rational being. Here is my individuality, my personality, in that which is the indivisible unit of my nature, from which I can not emigrate, and one attribute of which I can not amputate--the _I_! The thief may escape from justice, but he can not escape from the dishonest wretch--_himself_.
