_Apology for my change of opinion and belief in the existence and agency of Spirits._ 660. I do not conceive that in my change of opinion I have been involved in any inconsistency of principle. It always appeared to me that in explaining the planetary movements, after arriving at the Newtonian boundary made by momentum and gravitation, there could be no alternative between appealing to the spiritual power of God, or resorting to atheism. An appeal to the power of God has always been my choice; nevertheless holding that wondrous power to be of a nature wholly unintelligible to finite man. (57 to 87.) 661. Confining the range of my philosophy to the laws of motion, magnificently illustrated by the innumerable solar systems, but no less operative in every minute mechanical movement, I hold that I could only come to the same conclusion as Faraday, that if tables _when associated with human beings_ moved, it must in some way be due to those beings, since, agreeably to all experience of the laws of matter in the _material_ world, inanimate bodies cannot originate motion. But as when the planetary motions are considered, any hypothesis fails which does not account for the rationality of the result, and therefore involves the agency not only of a powerful but a rational cause; so the manifestations of Spiritualism, involving both reason and power, might consistently justify me in looking for agents endowed with the reason and power manifested by the phenomena. This power being _invisible_ and _imponderable_, and at the same time _rational_, there was no alternative but to consider it as _spiritual_, no less than that to which planetary motion is due. In its potentiality the power thus manifested might be extremely minute as compared with the potentiality of the Creator; still it had to be of the same spiritual nature. 662. It has not appeared unreasonable to infer that the soul in assuming the spirit form should acquire a power of which material beings are destitute, and of which they can only conceive an idea from its necessity to the operations of God. Parting with its material attributes, were the soul not to acquire others, even if it could exist, it would be perfectly helpless. Hence, in becoming an immaterial spirit, it must acquire powers indispensable and appropriate to that state of existence. 663. Since we know that the animal frame for the most part after death, on the exposure to the air, warmth, and moisture, returns to the atmosphere whence it is mainly derived, it follows that on undergoing that awful change the soul must take the spirit form, unless it perish with its material tenement. So far, then, all who believe in the immortality of the soul, must concur with spiritualists that on dying we become spirits.
