“If the artist is necessarily sensitive, does that sensitiveness form in its essence a state constantly liable to shade off into the morbid? Does this liability, moreover, increase in proportion as the effort is great and the ambition intense?”

Context: It's not the machine itself that does the trick. The machine merely acts as an intermediary between the sensitive and the spiritual force. It is an extension of the sensitive. It magnifies the capability of the sensitive and acts as a link of some sort. It enables the sensitive to perform his function.

Context: The very nature of intelligence is sensitivity, and this sensitivity is love. Without this intelligence there can be no compassion. Compassion is not the doing of charitable acts or social reform; it is free from sentiment, romanticism and emotional enthusiasm. It is as strong as death. It is like a great rock, immovable in the midst of confusion, misery and anxiety. Without this compassion no new culture or society can come into being. Compassion and intelligence walk together; they are not separate. Compassion acts through intelligence. It can never act through the intellect. Compassion is the essence of the wholeness of life.

Address to the Society for Psychical Research (1897)
Context: These rays, as generated in the vacuum tube, are not homogeneous, but consist of bundles of different wave-lengths, analogous to what would be differences of colour could we see them as light. Some pass easily through flesh, but are partially arrested by bone, while others pass with almost equal facility through bone and flesh.
It seems to me that in these rays we may have a possible mode of transmitting intelligence which, with a few reasonable postulates, may supply a key to much that is obscure in psychical research. Let it be assumed that these rays, or rays even of higher frequency, can pass into the brain and act on some nervous center there. Let it be conceived that the brain contains a center which uses these rays as the vocal chords use sound vibrations (both being under the command of intelligence), and sends them out, with the velocity of light, to impinge on the receiving ganglion of another brain. In this way some, at least, of the phenomena of telepathy, and the transmission of intelligence from one sensitive to another through long distances, seem to come into the domain of law and can be grasped. A sensitive may be one who possesses the telepathic transmitting or receiving ganglion in an advanced state of development, or who, by constant practice, is rendered more sensitive to these high-frequency waves. Experience seems to show that the receiving and the transmitting ganglions are not equally developed; one may be active, while the other, like the pineal eye in man, may be only vestigial. By such an hypothesis no physical laws are violated; neither is it necessary to invoke what is commonly called the supernatural.
