``The sun lights up space, as much at midnight as at midday.

She walked with him along the street; then she disappeared. Surprised, startled, and terrified, he telegraphed to his son, and learned both the sickness and the death of his daughter-in-law.
``We are absolutely obliged to admit that SOMETHING emanated from the dying woman and touched her father-in-law. This thing unknown may have been an ethereal movement, as in the case of light, and may have been only an effect, a product, a result; but this effect must have had a cause, and this cause evidently proceeded from the woman who was dying.

One feels that there is a force unknown, proceeding, not from our physical organization, but from that in us which can think.
