To be "meek and lowly in heart," so as to seek help in learning what is right from every source, however humble or however imperfectly offered, is the surest indication that a mind is under the entire control of a ruling purpose to do right, and is thus _a perfect mind_. Such a mind, it must be seen, has _tendencies_ that _fit_ it to that great system of things in which we find ourselves. Such a mind can not trace out these tendencies by the light of reason alone without a conviction that _somewhere_ in the progress of ages it will attain to a _perfect commonwealth_, where the great end and object of the Creator in forming mind will be carried to entire perfection in each individual mind and in the all-perfect whole! CHAPTER XXX. ON THE PROBABLE EXISTENCE AND CHARACTER OF DISEMBODIED SPIRITS. We have considered the mode by which, without revelation, we arrive at a knowledge of the existence and character of one eternal, self-existent Creator, and of other _eternal beings_ endowed with all the attributes of the human mind. We will next inquire as to the existence of other created minds in addition to those whose existence is manifested by a material body. There are several principles of reason to aid us in this inquiry. The first is that which establishes the existence of mind and matter as two distinct and diverse causes or existences. By this we decide that every human being has a body and a soul. The second principle of reason to guide us is that which teaches us to believe that things continue to exist as they are and have been, unless there is some known cause to destroy or change them. The other principles to guide us are, that nothing is to be assumed to be true unless there is some evidence that it is so, and, in case of conflicting evidence, the _balance_ of evidence is to decide what is right and true. These principles being assumed, we find that at the death of every human being we have evidence, first, that the body ceases to be connected with the spirit, and is dissolved. Next, we have evidence at the period of this dissolving of soul and body that the soul exists without a body, and no evidence that it is changed in any of its powers, or habits, or character. Thus we arrive at the conclusion that the spirits that have existed in this life connected with bodies are still existing with all the powers, habits, and character which they possessed in this life, except as they are modified by causes and tendencies that experience in this life has disclosed. We thus infer that all minds who have left this world have continued in the upward or downward tendencies of character which existed when they were disconnected with the body. This is all the knowledge we can gain by reason and experience alone in reference to other created beings, and their character and mode of existence.
