Spirits around me were insisting that it was they individually that aroused life in themselves, supposing that they aroused the objects of thought and so, lived from themselves. But I was prompted to tell them that nothing stirs up thought if there is not an object, so this happens through the eye and the ear, and then from the memory-otherwise there would be a confusion of everything-and that these objects can come from no other source than the one only fountain of life, the Lord, and that they are varied according to the natural characters of the spirits. From one to the other there pass the objects of ideas, or mental imagery, so that they suppose them to be from the others and from themselves, which is most false. The eye cannot see without light, nor the ear hear without sound, and so on. 1748, 4 Aug.
