“The soul seems to reside in the judgment, and the judgment would seem to be seated in that part where all the senses meet; and this is called the Common Sense and is not all-pervading throughout the body, as many have thought. Rather is it entirely in one part. Because, if it were all-pervading and the same in every part, there would have been no need to make the instruments of the senses meet in one centre and in one single spot; on the contrary it would have sufficed that the eye should fulfil the function of its sensation on its surface only, and not transmit the image of the things seen, to the sense, by means of the optic nerves, so that the soul — for the reason given above — may perceive it in the surface of the eye.”

Letter to Thomas Poole (16 October 1797).
Letters
Context: From my early reading of Faery Tales, & Genii &c &c — my mind had been habituated to the Vast — & I never regarded my senses in any way as the criteria of my belief. I regulated all my creeds by my conceptions not by my sight — even at that age. Should children be permitted to read Romances, & Relations of Giants & Magicians, & Genii? — I know all that has been said against it; but I have formed my faith in the affirmative. — I know no other way of giving the mind a love of "the Great," & "the Whole." — Those who have been led by the same truths step by step thro' the constant testimony of their senses, seem to me to want a sense which I possess — They contemplate nothing but parts — and are parts are necessarily little — and the Universe to them is but a mass of little things. It is true, the mind may become credulous and prone to superstition by the former method; — but are not the experimentalists credulous even to madness in believing any absurdity, rather than believe the grandest truths, if they have not the testimony of their own senses in their favor? I have known some who have been rationally educated, as it is styled. They were marked by a microscopic acuteness; but when they looked at great things, all became a blank, and they saw nothing, and denied that any thing could be seen, and uniformly put the negative of a power for the possession of a power, and called the want of imagination judgment, and the never being moved to rapture philosophy.

1961, Speech to Special Joint Session of Congress
Context: I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth. No single space project in this period will be more impressive to mankind, or more important for the long-range exploration of space; and none will be so difficult or expensive to accomplish. We propose to accelerate the development of the appropriate lunar space craft. We propose to develop alternate liquid and solid fuel boosters, much larger than any now being developed, until certain which is superior. We propose additional funds for other engine development and for unmanned explorations — explorations which are particularly important for one purpose which this nation will never overlook: the survival of the man who first makes this daring flight. But in a very real sense, it will not be one man going to the moon — if we make this judgment affirmatively, it will be an entire nation. For all of us must work to put him there.
