Spirit  

"Thus we must not be astonished if the world is filled with vain and ridiculous opinions, and nothing is more capable of making them current than ignorance, which is the sole source of the false ideas that exist regarding the Divinity, the soul, and the spirit, and all the errors depending thereon." --Treatise of the Three Impostors

I know it is in you
And it won't leave you alone
I'm talking about the spirit

--"The Spirit's in It" (1981)

"After having forged these Gods they were curious to know of what matter they consisted, and finally imagined that they should be of the same substance as the soul. Then being persuaded that the latter resembled the shadows which appear in a mirror, or during sleep, they believed that some Gods were real substances but so thin and subtle that to distinguish them from bodies they called them Spirits. So that bodies and spirits were in effect the same thing, and differed neither more nor less, and to be both corporeal and incorporeal is a most incomprehensible thing. The reason given is that each spirit has a proper form, and is included within some limit, that is to say that it has some boundaries, and consequently must be a body however thin and subtle it might be." --Treatise of the Three Impostors

"I cannot conclude these details of some very singular passages in a life at all times sufficiently eventful, without again recalling to the attention of the reader the merits of that indiscriminate philosophy which is a sure and ready shield against those shafts of calamity which can neither be seen, felt nor fully understood. It was in the spirit of this wisdom that, among the ancient Hebrews, it was believed the gates of Heaven would be inevitably opened to that sinner, or saint, who, with good lungs and implicit confidence, should vociferate the word "Amen!" It was in the spirit of this wisdom that, when a great plague raged at Athens, and every means had been in vain attempted for its removal, Epimenides, as Laertius relates, in his second book, of that philosopher, advised the erection of a shrine and temple "to the proper God.""--"Loss of Breath" (1832) by Edgar Allan Poe
