Сторінка 8 - A luminous and helpful idea is that time is but a relative mode of regarding things ; we progress through phenomena at a certain definite pace, and this subjective advance we interpret in an objective manner, as if events moved necessarily in this order and at this precise rate. But that may be only one mode of regarding them. The events may be in some sense in existence always, both past and future, and it may be we who are arriving at them, not they which are happening.
Сторінка 8 - May there not also be an immaterial (perhaps an ethereal) medium of communication ? Is it possible that an idea can be transferred from one person to another by a process such as we have not yet grown accustomed to, and know practically nothing about ? In this case I have evidence. I assert that I have seen it done ; and am perfectly convinced of the fact.
Сторінка 8 - The event may be in some sense existent always, both past and future, and it may be we who are arriving at them, not they which are happening. The analogy of a traveller in a railway train is useful. If he could never leave the train nor alter its pace, he would probably consider the landscapes as necessarily successive, and be unable to conceive their co-existence. The analogy of a solid cut into sections is closer. We recognise the universe in sections, and each section we call the present.
Сторінка 8 - A vulnerable spot on our side seems to be the connection between life and energy. The conservation of energy has been so long established as to have become a commonplace. The relation of life to energy is not understood. Life is not energy, and the death of an animal affects the amount of energy no whit; yet a live animal exerts control over energy which a dead one cannot.
Сторінка 60 - Puffballs, which some of our friends have not inaptly compared to sweet-bread for the rich delicacy of their unassisted flavour ; Hydna as good as oysters, which they somewhat resemble in taste ; Agaricus...
Сторінка 8 - And if we once grasp the idea that past and future may be actually existing, we can recognize that they may have a controlling influence on all present action, and the two together may constitute the 'higher plane...
Сторінка 200 - This very materially assists in the process during the night, and leaves the tissues fresh and strong, ready for the active work of the day. Hot water is one of our best remedial agents. A hot bath on going to bed, even in the hot nights of summer, is a better reliever of insomnia than many drugs. Inflamed parts will subside under the continual poulticing of real hot water. , Very hot water, as we all know, is a prompt checker of bleeding, and besides, if it is clean, as it should be, it aids in...
Сторінка 8 - And after all, when we have grown accustomed to it, it will not seem altogether strange. It is, perhaps, a natural consequence of the community of life or family relationship running through all living beings. The transmission of life may be likened in some ways to the transmission of magnetism, and all magnets are sympathetically connected, so that if suitably suspended a vibration from one disturbs others, even though they be distant ninety-two million miles.
Сторінка 60 - I have this Autumn myself witnessed, whole hundred-ioeights of rich wholesome diet rotting under trees ; woods teeming with food and not one hand to gather it ; and this perhaps in the midst of potato blight, poverty and all manner of privations, and public prayers against imminent famine.
Сторінка 8 - ... a body may not be moved without ordinary material contact by an act of will ? I have no evidence that such a thing is possible. I have tried once or twice to observe its asserted occurrence, and failed to get anything that satisfied me. Others may have been more fortunate. In any case, I hold that we require more knowledge before we can deny the possibility. If the conservation of energy were upset by the process, we should have grounds for denying it ; but nothing that we know is upset by the...
